k5 compression ???

<< < (2/2)

I've always gotten high compression with a new top-end. Usally once the rings set, it goes a little and gives a little more room. Is the cylinder fresh too or just the piston? I don't see a need to run race gas with the KX unless you've done some serious work. I had my head and cylinder cut for race fuel and had to run it. I purchased barrells of C12 from VP Racing to keep it alive. Infact, I still have about 30 gallons of it sitting. I don't even know what to do with it. :-) Maybe run it in my street bikes or MX bikes? lol

Goodluck

yup , it's a fresh 88 mm milenium tech re-plated and new wiesco . But I'm unsure about the head gasket now as I see 3 different ones are available ? Top end runs great , low end runs rich , and the mid pings . I just put in the 58 pilot (had a 60 ) , and lowered the clip to the mid (was in 2nd from top )(stock needle) and put in a 168 main (has 170 ) . I hope to be close  :|

Keep playing with your jetting, if your lowend is rich and you are sure about your crank seals, ect. Try loweing the clip 1 more to see how it results. Believe me, even if it is running a little rich you are losing power and fuel.

PS: Check the forsale forum. I've got a few needles, pilot, & mains if you want some experimenting jets to help you.
