idle speed for a warmed over kat

[89katana750]

What would you guys think the idle speed should be for a kat with gsx-r cams and rockers?

uhhh, find out what a stock gsxr is that would be your best bet seeing as its almost hte same motor just a different stroke. also hte kat should be around 1100 stock so figure more lift and duration from the cams so maybe a lil higher??

Set it to 4000 so that you have all the power straight off the line 8) j/k

The Haynes says 1200 +/- 100 for GSXR 750 91-92, 1100 +/- 100 for the 85-90 if it's of any help.

That's what all the GP racer bikes are set to -- for that reason, too

Mine sits around 1500 and it is a 89 750 Kat. It was set up for drag racing when I bought it. So set it somewhere around 1500 and you will be fine. If mine is set lower it runs like crap.

Odd , mine's set at around 11-1200 .

That's odd... sounds like someone did some tinkering and as a result the stock idle circuits aren't working ideally.

Question: your ride profile says you're running a stage 2 jetkit... who offered a stage 2 for that engine? I thought the various vendors offered only stage 1 & 3 for the '89 Kat 750... (DynoJet is 1 & 3; Factory Pro is 1, 1.1 [titanium] & 3). Curious...

Mine does run better when it is a bit higher than 1100. 1500 sounds a bit too much, I need new spark plugs before I can fully test because I fouled them when I added a bit too much oil in the spark plug holes before i started it. It runs good when it is cool/cold, but once it warms up it wants to die sometimes.
