Center stand - GN250

[bpdchief]

Just bought a centerstand off a 1988 GN250. I'll post "how to" mounting pictures and this should answer the question of "can I put a centerstand on my GZ250". My wife is going to kill me if I don't stop buying things for this bike :whistle:

Looking forward to this. So far all searches for a GZ centerstand has been a no-go. There was some mention of a GN stand but never any actual results. Sure would make chain lubing a lot easier. Have at er.

From what I read, they used the same frame since 1982 and carried it over to use on the GZ. Waiting for it to arrive, but, what I can see is that on the GZ there are two frame connecting bolts under the swing arm - when a centerstand was offered the pivot tube was the spacer and one long bolt was used... we'll see if that theory pans out very soon. Stay tuned for News and Film at 11. Always heard that on the news teasers when I was a kid.

:lol: :lol: :lol: :lol: Oh my how times have changed since you and I were kids. Instant gratification is the theme and I want mine now or I'll hold my breath till I turn blue................Hmm, there's a flaw there somewhere. Carry on.

Doing more studying on this project... 1988 GN250 had a ground clearance of 6.3 inches compared to the 2007 GZ250's 4.9 inches. That tells me a little more lift and more rear tire clearance for chain oiling and other rear maintenance :)

The new TU250 is more based on the GN250 with its straight seat and 60's street bike appearance rather than the cruiser look of the GZ250.

My sister said I used to get mad and hold my breath til I passed out, but, I can't remember and she was always just a little :crazy: anyhow.

With less ground clearance the GZ will require a little more muscle to put it up on a center stand. Once you develop a routine it will be no problem. You may want to consider a handle of some sort near the left side of the seat so you can lift safely(right hand) while putting your weight(right foot)down on the centerstand foot tang thingy. The left hand is usually used to steady the bike holding the left grip. Until you are comfy you can always park it in gear so when you drop it down off the stand it will not try to roll away. Don't laugh, I've seen it happen.
When I had rear lowering links on the Vstrom it was a fair lift to get it up. I soon learned not to try for the centerstand with a full tank and all the luggage packed for travelling.

Granted it was made for it, but, I always used the centerstand on my GS1000E when packed for traveling (remember it was fully dressed like a H-D Roadking). It was a beast to get lifted that 1 inch... pushing down on the stand, lifting up one the grab bar and pulling the bike backwards to rock it up onto the stand. Of course, there is a difference between 900 lbs fully loaded big bike and 330 lbs little bike. It will be an interesting learning event.

The GN250 got its additional clearance from a 3.00-18 front tire and 4.60-16 rear compared to the 110-16 front and 130-15 rear in the GZ. I'd sure like to find a set of those GN cast wheels and try them out... as sharp looking as the fella on here with the chinese cast wheels on his GZ

Oops, my bad memory. :cry: I had forgotten you had the big Suzuki years ago. Oh well, hopefully my comment wil help some one who has no experience. :lol: :lol:

This is exciting...

There have been a couple of other projects using cross-over pieces in the past that didn't pan out.
Even if this is a little more involved, I hope you can nail it.

LOL. I think it will.

For what it's worth, it was a lot of work to get my 82 GS450 up on the center stand. It had been bobbed and lowered (frame cut and rewelded). The centerstand was shortened a bit, but not enough to make it easy. You either 1) really had to muscle that sucker with your upper body, or 2) try to leverage it back and forth, but in doing so almost always rack your shin on the footpeg once it got up on the centerstand. I often opted for #2 because I was face-beat-red dead tired after doing #1 a few times.

When I sold it, I warned potential buyers that they may want to plan to spend some money to get a kickstand installed. Most of them looked at me like it was not a big deal until they actually tried to put the bike up on the centerstand. After which they looked at me like, "Holy crap that's hard."

Back when the Earth was still cooling and I had my Suzuki GT750 I used the Center stand and it was easy. That is until I removed the OEM handy dandy lifting handle to install a rear rack. The long flat arm of the rack was like a cutting tool when lifting a full size bike. Shouda coulda kept that bike.

All right kids... the adventure starts in the morning. Stand arrived and I finally have two days off. Hopefully it goes smoothly, otherwise, it will be a drawn out affair done as pay permits O_o .

I'm going in boys... if I'm not back in three days. Hell forget it, none of you would wait three days for me anyway :neener:

You got that right. :poke2:

The GZ has 4.9 inch ground clearance, the GN had 6.3 . The center stand is 11 inches from foot to center of the pivot tube. Looks like after I get a mounting plate designed, cut and put in place I'll be cutting an inch or so off the legs. We'll see how hard it is to lift on the long legs (IF they're not too long which I think they will be). Pics of the beginning coming tomorrow.

Most of today was devoted to house cleaning :sad:, and I finally raised the needle in the carb - what a difference that made :2tup:

Yep!! Makes all the difference in the world!! :) :cool:

Started trying to figure out how to mount this center stand. Not being able to locate a GN250 to look at is putting a serious damper on my project. The ground clearances as previously stated are 6.3 for the GN and 4.9 for the GZ. The stand is 11 inches from pivot tube to the feet.

http://s13.postimage.org/7d7edmnhf/Just_Pictures_003_2.jpg (http://postimage.org/image/7d7edmnhf/)

Pictured below - 11 inches from the ground is a 5.25x5.25 hollow frame box incorporated into the swing arm mount. Once a 5x5 mounting plate with ears for the pivot pin is fabricated, this box is the only place to mount said plate, and then, for the stand to offer any lift and stability it would have to be bolted through a minimum 2 inch long tubes to give any lift to the back tire.

http://s11.postimage.org/glmowf5vz/Just_Pictures_004_2.jpg (http://postimage.org/image/glmowf5vz/)

Then there is the question of that odd shaped metal bracket sticking out with nothing attached.

Now.. 1. Do I make said mounting plate and see if it and the supporting legs can be bolted through the hollow box and use the whole center stand???

http://s12.postimage.org/bs9s6km3t/Just_Pictures_005_2.jpg (http://postimage.org/image/bs9s6km3t/)

2. Do I make a smaller plate, cut the legs down to 7 inches and bolt to the odd looking plate, or,
3. Do I say ya know, the side stand is working just fine and try to re-ebay the center stand?

Another issue is the chain is right in line with the stand spring, so the spring and foot bar would have to be relocated to the right side of the bike, making it necessary to lift from the right side of the bike to keep from the tension from the spring from tweaking the pivot tube.

Re-bay the stand and get one of these to be able to work on the chain or rotate either wheel -
