i just got a uni airfilter for my 250ex, do i need to rejet it? thanks

 

proboboly not

 

anybody else???

 

If all you did was put the filter on then no. If you're intending on running with the airbox lid off then yes.

 

I would say no, because that ridiculous metal screen that Honda uses, is probably more restrictive than any air filter.

 

reconranger, how did you get all those bikes?
how old are you (if you dont mind my asking)
cuz im 15 and i could barely afford my 400ex lol

 

Yes If you want to feel any gain at all rejet your carb.. It will only take a second and its worth it.. buy single main jets 3 up and 3 down.. then try them all with spark plug check your looking for a light brown or a tanish color.. This way you can get a outerwear or pre filter and run no airbox or lid off and feel the gain's

 

A new air filter will not give you enough extra air flow to re-jet.
