If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

WHAT SHOULD COMPRESSION BE FOR GS400?

Since my 1984 XS 650 died, I am thinking of getting a 1981 GS400. I am tired of buying bad bikes tho, so I need to know what the compression should be, and what the best way is to check it. Also, what size fork seals would I need? And what size chain? I do have the front end of my XS still with perfectly good new rubber.....I was wondering if I could swap the whole forks and all with the GS, though I guessed that wouldn't work. What about the wheel?

also, what chain does the gs 400 take? I went onlien to the suzuki site but there is no parts diagram.
 
Not sure about the GS400, but for the 81 GS1000, the compression is:

Normal range: 128-184 (180 something .. I think 184) PSI
Overhaul limit: 100 PSI

Don't make the same mistake I did when checking your compression. Make sure to hold open the throttle! :)
 
Re: WHAT SHOULD COMPRESSION BE FOR GS400?

My clymer manual lists compression as: 130-184psi. The service limit is 100psi. Max difference between cylinders is: 14psi.

The manual doens't list the chain specs. However, any self respecting suzuki dealer can look this up for you.

As for fork swapping, I doubt it would be easy. Its been said part A can be made to fit bike B with enough time and thought. If the tire sizes are the same you can probsbly swap those over easily enough, even if the wheels thenselves won't.
