Main jet - jetting on 250R ?

[ceaserthethird]

Well took the 250R out on the trails

Tryed different jetting size's , Not enuff gas -> 150 155 160 162 168 <- to much gas

Pain in the ass , Low to mid Run's awesome , mid to upper does nothing !!!:cry:

What the Hell is going on here ? :wondering

I have a Full - Bill's Pipes system on it with - K&N Filter & - Carbon Fiber Reed's !

I'll be parting it out soon ;)

What year R? Where's your needle? Is the slide opening all the way when the throttle is WOT? What does the spark plug look like? Open air box? Is the air filter clean?

What pre-mix ratio and brand you running?

Try a 150main and lean your mix to 50:1 and see what happens. Even remove your airbox lid and see how it runs then.
