My GZ Bobber - HARDTAILED!!!

[Kcarvajal]

Guys,

Updated pictures of my bike, hard-tailed using the Factory Metal Works Triumph universal kit.

First of all, thanks to Jonathan for the help with re-jetting the carb and the ideas of how to tone down the exhaust. Also to Kflint for the courage to tackle rejetting the carb.

As for the bike, I initially took it to a local fabricator. The end result however, wasn't to my liking. He offered to re-do it, but I'm not certain he can pull it off based on the end-result. So I tackled it myself, using the swingarm as a guide/jig. I wanted a 6" stretch, I got almost 7" from the fabricator. It worked to my advantage since I had to undo his work, and lost a couple inches along the way. It worked perfectly because the axle plates had a couple inches there also.

The universal kit matched since the GZ has a small frame. I originally ordered 34" top tubes thinking it needs to be mounted to the stem of the frame. The fabricator instead, attached it to the two top tubes from the original frame and used a slug to connect the new top tube to the frame. It works, but I didn't have to special order the extra length, I suppose. I took pics of the build process and will document it for those of you who are interested.

The front end is from a Savage. I originally used just the front wheel, but liked the forks since it's cleaner and longer by 2". I changed the rear wheel also with an 18" Kawasaki 650 (can't recall the model). Had to get a new chain for the length and the sprocket size.

I also re-wired it so the two rear tail/brake function as turn signals. I had to purchase a trailer light module, ($14 from AutoZone) to make it work. Quite simple actually. I used the original two front turn signals with dual filament sockets.

I also built a license plate mount as can be seen in one of the pics below.

The seat.. I removed the original cover and used an old leather jacket. I took pics of this process also and will compile them all.

It's still a work in progress. For instance, the exhaust, I would like to run down towards the bottom of the bike, instead of going straight back. I had to put it together so it's in riding condition to join my brother in law on a ride to a vintage british bike shop. With this setup, we were on the road for about 6 hours total.

Electronics are hidden in the fake oil tank (flour/Sugar container) and an ammo box.

Light indicators (Neutral/Turn) are installed on the top headlight since I lost the mounts from the original GZ Trees. It works well. :)

OK, back to work. More details later.

Thanks!
Ken




Previous Post:
Hi All, new here and new to riding. Just finished my MSF course yesterday as a matter of fact.

Anyway, I'm from Chicago and was recently given an approval to get a bike with a set budget. My research lead me to the GZ250, and found this site.

I lurked for a bit and knowing that I like a set style/look, I took some of the advice and procedures that others have done to customize their bikes.

That being said, below is my 2007 GZ250. I purchased this from Craigslist at a price that I couldn't refuse. Knowing the potential based on what I've seen here, I started ordering parts before even picking up the bike. A week later, this is how it looks and I can't be any more proud.

FYI, The exhaust came with the bike. I wasn't too crazy about it at first with the original stock parts, but with the exhaust you see here. However, knowing that I will be converting it into a bobber, I figured I'll see how it looks after. I'm pleased, and the sound is great!

Parts: New Handle Bar, rigid struts, new side mirrors (actually even lower since I used the parts from the original mirrors. I can see wider now.), solo seat, rear fender was the front fender that I cut and mounted using L brackets from Home Depot, License Plate and tail/break light is mounted on the opposite side, turn signals front and back.

Anyway, this is the pic of my bike. ;)

EDITED: Updated picture, with sporty tank, new side mirrors, and 19" Savage front wheel. Axle fits perfect, offset is also close to perfect with the caliper. Only issue is the speedo, but I have ideas of how to make it work.

Welcome to the forum.Your bike looks good.Nice clean job.
:) :cool:

[Water Warrior 2]

Welcome newbie. Glad to have you join us. I am not a bobber fan but there is something about your bike that really tickles my fancy. Well done.

[mole2]

Welcome aboard from South Carolina. I usually don't like bobbers but this one looks good. Ride safe.

Just noticed........ There appears to be only one exhaust pipe. How does this work, when there are two outlets from the engine? :??:

I'm betting he's got duel exhaust.We just can't see the pipe on the other side of the bike.You can just see the curve of the other header pipe.
:) :??:

[Kcarvajal]

Thanks all! Glad to be here.

Blaine is correct, the exhaust you see in the pic is mirrored on the opposite side.

BTW, I'm planning on taking my skills test tomorrow to get the M on my drivers license. I struggled with the sharp left U turns while taking the MSF course but practiced quite a bit yesterday on my own bike on an empty lot. I was using two parking spaces as markers and was able to get it 80% of the time (I think). I believe the U turn test is within a 20' distance. Parking spaces average 8' (as I was told) so I'm feeling better with this portion.

My concern is more with the stop and quick 90 degree right turn. I couldn't get it down for the life of me during the class. I intend to practice the U turns and cone weaving (12' distance x 2' off-set) and accepting that I will not make this 90 degree turn.

I wanted to run it by you guys if you have any tips on any of the maneuvers, and how to calm the nerves prior to the test. :)

Thanks all!
Ken

Tighter turns and parking lot stuff is a lot easier if you look where you want to go. A bad habit I fight is looking down a bit too much just in front of the wheel. Turn your head and look where you want to go.

[Kcarvajal]

I agree, I tend to do the same thing. However, for me at this stage anyway, it's a lot easier than it sounds. Along with just turning your head, it seems I need to also have good control with the throttle so I don't stall in the middle of a turn, which happened twice and dropped the bike both times. Luckily I was able to catch it but got one minor scratch on my tank. :cry:

Is this the wrong approach or is it you set a good speed and just cruise through the turn sorta thing?

Anyway, I'll practice again later if it doesn't rain and will update you guys tomorrow afternoon, hopefully as a licensed motorcyclist.

Very slow manuevering can be easy with practice. You need to learn throttle control, clutch control and the use of the rear brake. Slipping the clutch at an increased RPM(not a whole bunch) and just dragging the rear brake will keep the bike steadier and more planted. This will help govern your speed while you look ahead to where you want to go. "Keep Your Head Up." Put some thought into it before trying it. It does work and works well. The clutch is oil cooled and will take some abuse without damage, just don't rev the engine to an overly high RPM. You can do it and the parking lot scene will become easier and easier with time.
Practice just going in a straight line as slow as possible with using the rear brake, clutch and throttle. When the confidence level is good add some turns and U turns. Word of warning: do not apply the front brake when in a slow turn or U turn as that will dump you promptly. Don't ask me how I know. :whistle:

Just remembered. Pick up a copy of Proficient Motorcycling by David Hough. The bible of motorcycling will teach you things of extreme value when it come to riding on 2 wheels.

[Kcarvajal]

Thanks Water Warrior! I will certainly pick up that book. I need as much knowledge as I can to help me with safety, etc.

I wasn't going to take the test this morning since I didn't get to practice last night. However, I decided to go for it and PASSED!!! :2tup: Went to DMV immediately after, got the M on my license, went home and went for a ride. It felt good riding around my area having the proper license.

Although, some dude was behind me while in the right lane, he sped up to me left, then kinda went into mine and slammed his breaks. I think he was trying to freak me out or something. I don't know. Didn't scare me, but just wasn't sure what that was all about. :??:

Anyway...

Thanks all!

Ken

[Water Warrior 2]

Sounds like a touch of road rage and stupidity. Best to practice some emergency braking too.

[geezer]

dude get used to that quick. its common for cagers to look right at you then pull out in front of you. always have an escape route planned! take this seriously!

Congratulations!!!

As for the dude. You were probably going to slow for him and road rage set in. He was trying to show you his displeasure...even if it kills you. It's common so get used to it and be defensive. They're ALL trying to kill you out there. You have to remember that on each ride.


:)

[Kcarvajal]

Guys, thanks!

I have since picked up a copy of Proficient Motorcycling and started reading it on the train this morning. Glad to have it.

Mole2, I think you might be right. I was coming out of a right turn into the lane, and then another right to go into Starbucks parking lot. He was behind me from the initial rturn and more than likely was upset that I slowed him down.

I will be going to another Starbucks for a while until I get more seat time. ;)

Thanks again!
Ken

Sweet Bike

[Kcarvajal]

Placement of the indicators. I sanded the headlight case to give it a patina look, matching the tank. Close anyway.

[Peachy140]

Ken the bike looks amazing. Have to admit Im a little bit jealous my technical expertise extends as far as changing spark plug and battery. Good job mate and as the old adage goes if you want it done right do it yourself :)

[Kcarvajal]

Thanks Peachy! Honestly, I too was intimidated. But the help of the folks here made it possible.

It's not quite as hard as you think, however. My suggestion, on a specific modification, either dig it up here if it already exists, or post your question. My experience has been someone is always either able to help, or give you pointers to try.

Send me a PM if you're interested in a specific one. If it's something I've done, I'd gladly document the steps for ya.

Good luck, and thanks!
Ken

[Peachy140]

Thanks Ken, thats exactly how i found the forum. I was looking for an answer to a question which i googled and the top 2 or 3 answers had links here and honestly im very happy to be here. I had my own idea as to a few remaining niggly issues on my Marauder, the forum folk suggested other possibilities and after speaking to the mechanic who worked on my bike last he actually confirmed what people on here said it would be...

Havent had the time recently to do anything to the bike except ride it to and from work. Once Ive got the running problems sorted, ill give the bike a good clean up and am contemplating getting the chrome redone. Looking at your hard tail made me drool though I dont know if going that far on my little 250 is justifiable. I know for a fact i cant justify the cost to the Mrs. Oh well maybe I can offer her the option of pimping up my 250 or buying something a little bit bigger and shinyer :)

[Kcarvajal]

You know, there's always that where I should have just spent the cash in getting a bigger or another bike. However, I'm in a similar boat where getting this first bike OK'd by my wife was difficult as it is. A little over 5 months ago, I never thought I'd actually own one, let alone a bike that I would literally tear apart and re-build.

I'm a new rider, but love the style of bobbers. If I had gotten a bigger, more expensive bike, I would not have had the guts to tear it apart and make it into what it is today. I spent very little on the bike... considering. Sure it's only a 250cc, but I don't really foresee myself being on the highway much to need a larger motor and speed. At least not right now as it seems plenty for me as it is. I just enjoy cruising around, and not so much holding on to dear life down a highway.

Anyway, the hardtail wasn't that bad. If I had known I can pull it off from the beginning and not relied on the fabricator, it would have only cost me around $250. The rest of the parts I bought were either through ebay, or Craigslist. As for the whole project, I'd say, do it a bit at a time.

I won't encourage you to tackle the welding portion though, if you don't feel comfortable. The deal here is to ensure you get enough penetration to the pieces. Practice as much as you can before doing it to your frame. This is my first real welding project, the first being a Z style handle bar. Came out great, but I don't think I will be using it. I like the drag bar better. ;) But based on riding for most of the day this past Saturday, I'd say I'm in good shape. It's rigid, that's for sure! So get a comfy solo seat!

I will take more pics after I finish the exhaust.

Ken

[Peachy140]

Had a drag bar on both my Virago's and to be honest i didnt like it. I much prefer to be sat upright and in a comfortable relaxed cruising position.

I think re-chroming is definately a must on my marauder. My profile pic isnt great but you can see that the handle bars, forks and various other bits need some tlc.

[Kcarvajal]

I haven't been here in a while. Just wanted to share a few updates on my bike.

Since my last post, I have lowered the front forks by 3 inches, reduced the size of the battery box, installed a hexagon shaped pseudo oil tank that hides most of the electrical, moved my seat back a few inches, replaced the intake with a harley air cleaner/filter and installed a modified triumph exhaust pipes. Also installed inverted handlebars. Now I just wish I could ride the darn thing. Maybe tomorrow, upper 40's.

Still need to figure out how to properly place the ignition switch. Reading some of the posts, there's some sort of a security thing that prevents you from hot-wiring the bike. I wanted to run it to the oil tank, using a universal switch that I already purchased. Any suggestions on this, I'd greatly appreciate it.

Hope you guys like it. Any questions, let me know.

Thanks!

Awesome work! Congrats Kcarvajal! Master piece and porn for bobber-likers! ;)

[Kcarvajal]

Awesome work! Congrats Kcarvajal! Master piece and porn for bobber-likers! ;)

Thanks for the kind words PimpS! I meant to add the rear lighting updates also. My tail lights function as marker, signal and brake. I used a trailer light module. I also added a 9 LED strip that I JBWelded under the fender to add more brake lights. Pic below is just a mock up of the strip which is just sitting on the tire, before making it permanent with the JBWeld.

Thanks again!
Ken

[PimpS]

Whew! Wicked man! Just wicked! Looks like a octopus is lurking in the back of the road...
I take down a back seat and saddle bags and pretend to have a bobber! ;)
Creativity + technology = progress!

[Kcarvajal]

Yeah man. Need to be a little more visible at night besides just the tail lights I had. Can't wait for riding season. I plan to ride the heck out of it.

Ride safe!

Ken

[bpdchief]

Great job on the bike!! Congrats.

[Kcarvajal]

Just recently revisited and didn't see your post til now. Thanks bpdchief!

Here's the latest... I just can't leave this thing alone. First one is with the stock headlight, minus the edge on the DIY paint job. Second is from this past weekend ride, new smaller headlight. Just ran everything back tucked under the tank. Ignition key has been relocated to the fake oil tank.

Pardon the messy garage.

Damn Kcarvajal! You keep on making your GZ better and better! Your an inspiration! Keep it up!

[PimpS]

Kcarvajal! You outdid yourself! I wish i had enough money and specially your skills to buy one extra gz and do that... What a BEAUTY!!!

You rock, man! :rawk: :2tup:

[Kcarvajal]

Thanks guys! I'm seriously learning as I go. Folks on this site have been extremely helpful. If you have any questions or need pointers, feel free to ask and I'd gladly share my experience.

No more plans to make drastic changes, other than maybe a rear fender stay. I just want to ride it this season, but when the time comes to replace the tires, I'm thinking of getting those old firestones.

Thanks fellas!
Ken

[mithuth]

I'm kinda diggin this. Nice work, thanks for sharing.

edit to add: by sharing, I mean inspiring.

[joe]

wow...thats its a great job, really a beuty, cheers...
