Replace flat back tire

[GZ surfn]

Help! Help
Just got a flat on my back tire. New to bikes. I think I know what to do , except how to jack the bike up!. Feel lame saying that but I am not sure where to lift with a jack. That and any other main pointers would be much appreciated. Bought the bike used but only has 700 mi. Dont want to cause damage or more trouble.
Much abliged.
Still trying to get a pic on this site and become sponsor. Will keep at it.
Looking forward to that 16 tooth sprocket in the future. hope to help others

I use a small floor jack with a shop towel for padding. Put it under the right side of the frame and jack it up until the wheel is off the ground. It forms a tripod between the front wheel, side stand and the jack.

Located elsewhere in this forum are some home built jack stands.

For wheel removal see the service manual also located else where in the forum.

Google for tire repair. (http://tinyurl.com/2xve7o) Their is more info than you'll read.

Dan's Motorcycle Tires and Tubes (http://www.dansmc.com/tires1.htm) is a good practical place to start.

Your going got need some tools, a new tire, and a tube. The general consensus is that you should consider and repair to a motorcycle tire temporary and replace the tire and tube ASAP. On a motorcycle your life depends on your tire so I find this hard to argue with.

If you have never changed a tire get ready to work up a good sweat. I do all my tires myself.

Few people have your combination of mechanical ability and sheer guts ! :roll:

I've done it before but never again.

In addition to sweat, one should expect a lot of cussing, skinned knuckles and probably at least one ruined tube.........which you will notice BEFORE you get it all back together, if you are lucky. :cry:

If I understand your "jack triangle" method correctly, it's the same thing I do to oil the chain. I do not, however, think that is stable enough for anything more complicated that chain oiling or brake adjustment. Are you really saying that you recommend to others that this is appropriate blocking to change a rear tire? :??:

[Water Warrior 2]

Wrap a bungie or a strip of velcro around the front brake lever. Good way to help prevent the bike rolling. Be very careful cause even a smaller bike is heavy when you are pinned under it.

[Water Warrior 2]

Duh............I guess this would only work if you are dealing with the rear end of the bike.

Not recommending it. Just saying it can be done.

I have a motor cycle jack that I use. Not because its more stable but because I can get the the bike up to a more comfortable angle/height to work on it.

[Water Warrior 2]

And I just spent all afternoon crawling around on the floor doing oil changes.

401 miles and found my rear tire flat this morning.... Damn! of all of the bikes I have had, and all of the years driving, this is my first flat.!

So I want to take the bike in to have the tire changed/repaired... Wish I had a motorcycle jack... any ideas what type I can get for this?

[adrianinflorida]

Finally got around to putting the new rear tire on today, now that I've got that out of the way, not looking forward to the next time. :)

Seriously, not at all complex., just a nasty job. I did get to clean the chain thouroughly and lubed it, checked rear brakes, went ahead and replaced rear wheel bearings and took the black plastic mudflap/lower fender to repaint it black since it was faded. Time for a ride. :)

I am not sure where to lift with a jack.

I've noticed that under the bike there's a sort of metal plate with 2 holes in it. It looks to me as though it was placed there for a centre stand. Can anyone say if this is correct? If it is, has anyone seen an aftermarket centre stand, or can anyone suggest what it might be for? I'm mentioning this because it seems that a centre stand would raise the back wheel off the ground, or alternately, would this be a good jacking point? I'm thinking along the lines of adapting the top of the jack with a couple of pegs to fit the 2 holes, to keep the jack steady. I'd really appreciate any input on this before I try it.

[Sarris]

It probably is from the old GN-250 center stand from which the GeeZee was derived. An old GN centerstand may fit. No Promises.

Here is a photo of a 1991 GN-250 up on it's centerstand.

Thanks al for the info.. All good advise.... Had a buddy come over andwe used a car jack... Trickey, but it worked.... :2tup:

We used a car jack right under the the engine, just forward of the rear tire... Took some trial and error. Also used some plywood for added stability. And would have some act as a safety just in case. They can hold it all steady as you work. Be careful....

Adapting a hydraulic floor jack sounds feasible. I thought about it but was too lazy to persue the idea.

[adrianinflorida]

The welder at work made me a pair of jackstands. They look just like auto jackstands, but a bit narrower to fit side by side on a bike. I used the method you guys talked about, tilting the bike back on the sidestand, and sliding the first stand Unser the swingarm, etc

I use a motorcycle jack and strap it down good; got a low one (4 and 1/2 inches) and it just fits underneath. Have to balance it on the "black frame" under the bike, and also the exhaust pipe. To me, it seems like it can't be damaging the pipe at all (because of the weight on it), but does anyone think I'm wrong?

Now to see what the mounting part on the frame looks like

Instead of supporting the weight of the bike on the exhaust pipe, why don't you put a couple of pieces of 2x4 under there and rest the weight on the frame?

I actually have a "platform" bike/atv jack but ended up using a scissor jack out of an old car. That was lots easier but still not very stable. Need to check out the platform jack closer I guess but it just doesn't seem like there is enough room to get it where it needs to be.

I would be willing to be the guinnea pig for the GN center stand......if anybody knows where to get one. A bike with a chain and WITHOUT a center stand is just a pain in the ass. :shocked:

[Water Warrior 2]

Easy, the old car scissors jack can work even better. Bolt a chunk of 1/2 inch plywood to the base to give it more stability. And I agree, a chain bike should have a center stand. A center stand makes life much easier.

[music man]

Not unless you want the whole bike to go with it, of course then you would have a GN250 with no center stand, so you would still be f@#$ed. I drove by one of these today, same color and everything, the guy also has a 70'somethin suzuki 250.

I will keep my eyes out for one since you volunteered to be the guinea pig.

Yes, I was serious about that........as long as the price isn't TOO outrageous, that is! :cool:

All the parts are listed for sale new here Center Stand (http://www.mrcycles.com/fiche_section_detail.asp?section=91615&category=Motorcycles&make=Suzuki&year=1988&fveh=2082) for about $65.

:)

[music man]

65 bucks plus shipping and tax and shit is a lot to drop on a project that may end up being a pile of scrap metal laying in your garage.

[adrianinflorida]

I haven't looked, but do our subframes even have the necessary mounting points for the centerstand? There needs to be a place for the pivot (Horizontal bar from side to side) to mount to, and a spring mount. I'll get under the bike after work if I get a chance and take a look.

[Easy Rider]

Well I think that pretty well blows the theory.
It is obvious that THAT ONE will not attach to our plate with the two holes.
:cry:

[Water Warrior 2]

Find a GN 250 and do a side by side comparison. Use a tape measure too. The stand in the up position would be the most critical. 65 and tax would be a dream come true if it works.

I know where one is, I think I will go look at it today if I can get a chance.

The news is not good. Went to the shop for my new air filter (which did NOT fix my idle problem, BTW) and there was a GN 250 parked by the building. Just like the parts drawing indicates, the center stand mounts in a long sleeve; nothing like the flat plate we have. :cry:

Looked at the plate again and I'm not sure it is strong enough to mount a center stand anyway.

I accept what you're saying - so what the hell is the plate for, anyway?

[Sarris]

California Evaporative Emissions Control Canister.

???????? :whistle: Just my guess.

[Easy Rider]

California Evaporative Emissions Control Canister.


Could be but I think that mounts up under the gas tank. Why else would the Calif. gas tank have a smaller capacity ??

[Sarris]

I'm pretty sure the cannister goes below. See here: Evap Emissions (http://fiche.ronayers.com/Index.cfm/Module/Main/TypeID/26/Type/Motorcycle/MakeID/2/Make/Suzuki/YearID/45/Year/2004/ModelID/6954/Model/GZ250/GroupID/298827/Group/EVAPO_SYSTEM_E33)

Maybe the CA petcock is larger (??), accounting for smaller capacity, perhaps. Just a guess.

Also, when you saw the GN, did it look like a simple weld on piece of tube to install the centerstand?

:)

If so, why the two holes in the GZ plate?

[trykemike]

I found a use for the plate. I cut a piece of 3/4 plywood to fit in it after tracing an outline. I painted it gloss black to match the bike frame. I attached it using 1/4 screws and nuts that are counter sunk into the wood. I can tilt the bike on the side stand then slide a 6 X 6 block under the new pad then tilt the bike back
up verticle and slide a 2 x 4 under the side stand . I put a wedge in front of the rear wheel to prevent forward roll and have used this method for chain lube and adjustment and rim cleaning.

No. It appeared to be an integrated frame component.

Because that plate has NOTHING to do with a center stand.
I think Sarris is right; probably is where the evap. canister goes for the Calif. model.

[Easy Rider]

I've been doing something similar with a scissor jack but it's pretty unstable.
Been thinking about making a big block like what you describe.
What do you gain by having the piece of wood bolted to the plate ??

trykemike, to prevent forward roll you need a park brake. Get a strip of velcro and wrap it around the front brake lever to apply the brake. Works really well and when not in use just wrap the velcro around a mirror stem where it will always be handy.

[Sarris]

As for the holes, please look at part #14 and you will see two mounting studs in the cannister bracket that looks like it may go in those holes.

I'm, still not convinced we can't install a center stand. I guess I need to look closely at one and put my architect's eye to work......

Hey Easy re: the wooden plate. It alows me to ensure that the 6x6 block clears the muffler.

Hey WW thanks for the idea re: using the front brake as a parking brake that would allow easier rear wheel rotation rather than moving the 2x4 wedge. I used the wedge because after tilting the bike up on the block I thought ?????
