Extended air-screw. That big carb can be a finicky bitch off-idle.

Gen 4 450x - natural, formed in the right places for conversion. Nice tank, cap, petcock. Speak up if interested, I'll get a pic or 2 to ya. $100 plus shipping. IMS 3.1 or 3.2 I forget which.

For all it has going for it RM250 = FLIMSY. I'd vote for an Al chassis.

Good setup info here.

5th gear, WFO, more power.... I'm buying you a beer - that's PROPER 500 talk.

Didn't really notice any difference in either performance or jetting, but I left it in place because the fitup is much better w/ the airbox boot. Have heard that on a 250 you need to space the pipe as well to get the benefit, wondered if any of that applies to the 5 zero zero.

Quite possible it's in the porting, the motor had " trail port " listed when I got it - which I think is code for " I mightta ruined it ". So the cylinder is not ruled out - even though I thought EG gave it a clean bill of health. I'm thinking there's something else at work - alw...

Gettin worked over by this on an '01. Has a low RPM miss at 1/8 throttle, blowing back lots of premix into boot. Black plug, putting down too much carbon. No spooge. The miss fades away with increasing RPM. Can not cure w/ jetting - tried it all. The motor rips everywhere but has that little stumble...

KTM dropped that motor because KTM drops everything. Even if last years whatever actually happened to kick ass - if they kept it then it wouldn't be NEW.
