Question -
I have a /86 suzuki GSXR250. Anyways I've noticed the chain has can lose, on more than one occation its even fallen off. I was looking to fix it myself by either taking some links off the chain or maybe moving the wheel/tranny to thighten the chain. Personally removing links sounds easier but I'm not sure if this is the right thing to do nor do I know the proper way to remove links off of a chain. I was eventually planning to increasing the size of my rear sproket if  that would help with the lose chain. Any suggestions you might have would help out a lot. But I would like to know how to remove or add links to a chain properly for future klnowledge.Thanks

Hi Gerald.
 You are aware that there are chain adjusters on the rear of the swingarm, right?

 Well, if those are adjusted all the way out, then the only thing to do is to replace the chain and sprockets.

 Any time that you replace the chain (due to wear), you must replace the sprockets or the new chain will wear more quickly.

 And be sure that you get the correct chain for your bike.  Not all bikes use the same type or length chain, so be careful of that.  Your repair manual has detailed instructions and specs for all of that, so you order the correct parts as well as a number of other related and unrelated things concerning the bike.

 Shortening a chain which has stretched is a formula for disaster.  At best, it will break or come off while you are riding.  At worst, it will snap and get caught up in your wheel, causing you to crash.

Let me know what happens.
Good luck.

Hay Falcon,

Thanks for the tip, I found the chain adjustors on the control arm. It worked out great. Now I have another concern...My bike is old and worn out, but its got a lot of kick still left in her.
Recently I've noticed that when I change gears its not as smooth as it use to be. As well as me brakes have started slipping a little, does it work like most cars were the clutch fluid is the same as the brake fluid?
Anyways if it is or isn't how do I go abouts draining the old fluids for both brakes and clutch and replacing it.
Oh ya I don't have a owners manual, I couldn't find one on the make or model of the bike. When I bought it used about 6yrs ago, the deller said it was an old race bike he imported in from Japan. Which for me, its made it hard, even next to impossible to find parts.
The engine is still ok for awhile, but I looking to re-fabricate a lot of the other parts. Do you know of any other SUZUKI makes that I could callobrate into this bike to make it better, Faster?
I've been working on the body, fabricating new ferrings, planning out the paint job and designing new decals. I just need help on the technical asspects of this bike. Its no point having a bike that looks good if it doesn't run great.
Anyways THANKS for the tips and I hope you can help me get this old race bike running like it should.

Much appreciated,
GERALD

Hi Gerald.
 You don't need the owner's manual.  You need the REPAIR manual.  You can get them online through any number of catalogs and websites.  Any Suzuki dealer should be able to order the repair manual as wel as (if you really want one) the owner's manual.  The repair manual will have specs to tune up and service the bike as well.

www.denniskirk.com

www.repairmanuals.com

Those are some of the places to order a manual online.

 The clutch on the bike is called a "wet-sump" clutch.  It is lubricated with the engine oil.  You can drain the oil from the drain, which is at the lowest point under the engine.  The exact amount of oil that you need is also in the repair manual.  You need that repair manual to properly service the bike.

Good luck.
