help with new kawi

[just_ride01]

just bought first kawie a 2004 kx250 i'm a suzuki boy lookin for a change. really like the bottom end pulls real nice out of cornering but top end feels weak and any other tips? it's jetted and piped with a FMF shorty but my 40:1 fuel mix ratio seems a lil' smoky anybody found a real science to make 'er run a lil cleaner i dont wanna start fouling plugs or nothin. I'd appreciate any helpful hints or insight

If you're running a good synthetic 2 stroke oil and it's jetted properly..........you really shouldn't get much smoke.

wat bout mixture ratio 32:1? 40:1? 50:1? which oil's best? amsoil? farmoyl? or is just any decent 2 stroke hy-performance good enuff?

yes amsoil works well and so does yamaha 2t or maxima 927 you could do 40:1 on a 250 because it doesnt need to be screaming like a raped ape for an extended period to keep it goin. just watch your jetting. spooge can be fuel related too. do you use race fuel.

wats a good octane to mix with?

The service manual says 90 + Octane...

But i would use the highest grade at an ordinary gas station.
