WHAT SHOULD COMPRESSION BE FOR GS400?

[Anonymous]

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.
