alright...hesitation in the throttle is at all an time high.
You have a stock 250X.They bog,and are strangled from the factory.
The JD jet kit has an outstanding reputation in off-road motorcycling and about everyone on this board with a 250/450X has one along with the mandatory airbox mod you need to do.
The JD kit is cheaper than the F2 and works great.
Instead, rid yourself of the smog thing like this free, except for some JB weld :
http://www.crfsonly.com/forum/viewtopic.php?t=13482urlRead the 250X jetting database. You'll notice a pattern, because it works.Do a search, note how many guys posted what you did and now couldn't be happier.
See, you won't get a lot of responses sometime to a post like this because we all know what works, it's been proven a zillion times over 4 years and it's easy if you can follow simple directions.
A lot of folks don't want to get into 15 posts arguing what they know to be a fact, so they don't post at all if it's
another BOG question.
If you want rid of your bog buy the kit, install it as directed and modify the airbox like the directions clearly show you. Honda even thoughtfully molded in lines in the airbox to show you where to cut. No, you won't make the bike easier to drown.
and will the quickshot solve this problem?
NO
The Boyeson is a good product but will not rid the 250X of it's bog if the jetting is stock, period.
Everything Jaws (Joe) told you is on the money, go fix your bike. You'll be meeting the rest of it.
