[88 gixxer 750]

Hi,

I was just wondering if some one could let me know what the intake and exhaust valves should be adjusted too on my 88 GSXR 750?

I am looking at doing this before I start riding her again.

Any other tips of other maintenance to do while i'm in there would be appreciated too!

Thanks,

Jason

hey klipsch..U ever have a problem with backfiring?? Let me know..I gotta an '88 7fitty

Would suggest you tighten up the tolerance to .004 to .0045 I know my 86 runs a lot better when I take the time to do a better valve set than the factory wider tolerance. I make sure that is not tighter than the .004 ie .0035 is not acceptable.

i did at one time that usually means your lean
you know those old gix r starved for fuel from the factory, you can gain an incredible amount of power out of a jet kit and full exhaust

were exactly is it backfiring at, like what gear what rpm range and such

 

[spike52]

It backfired twice at 80-90 mph at about 7k rpms. and both times on small bumps in the road..AT same speed on smooth roads nada....And at high speed but low rpm's nada...I posted this ???? in "Bike talk" and got a few responses.....

it'd be that much longer 'till the next adjustment.

valves on early gsxr's usually tend to tighten up over time....

For the back fire-

Check the side stand swithc: Put your bike on a rear stand and see if the kick stand is "loose" if it is there are three fixes

1) Disconnect the side stand switch - just connect the two wires.
2) Get a stronger spring
3) Spend the $110.00 for a new kick stand.
