hey… i am thinking of re-jetting my 250R to get some more power (as well as an exhaust)… the exhaust is super simple, but I am wondering if anyone has experience fiddling with carburetors?
if not, i’ll have to take it to the dealerJuly 10, 2008 at 12:18 am #8612megaspazParticipant
If all you’re doing is putting on a slip on, you won’t need to rejet. If you do the full exhaust you will. I’ve talked to a couple of people and was actually told don’t bother with the rejetting. it’s not needed… So unless you’re gonna get a full exhaust replacement, I wouldn’t even worry about it.
If there’s anything more important than my ego
around, I want it caught and shot now…July 10, 2008 at 12:26 am #8613JirikiParticipant
it is a full exhaust (area p, quiet option)… however, a ton of people are re-jetting their 250s for peak power, power @ lower rpm, and overall bike usability…
usable range goes from 6-10k to 3-12k or so…
it is also supposed to help with a cold engine…. right now, there is an unpredictable “will it move?” moment when you are leaving from a stop sign with a cold engine. This is kind of freaky when turning out in front of a car… about 60% of the time it will happily go quickly, but 40% of the time it will completely bog down and slowly chug you into traffic…
also, if you are going to change your sprockets to reduce RPM @ highways speeds, you’ll really want the extra 2-3hp you’d get from rejetting + exhaust…
anyways, trying to figure out finances.. if i could get help from a forum member, then i’d be able to install sooner…

I wouldn’t dream of rejetting my own carb. Fortunately I have a friend who’s brilliant with bikes and loves to tinker. My jet kit is on the way from Dynojet.
