CRF 450R modded air box

Recommended Posts

Hi:

I have a 2005CRF450R and did the Reil Engineering larger airbox box, with a Twin Air Power Flow kit...with more air flow, should I

1)decrease or increase the size of the main jet? Currently I have a 165 in the carb.

2)Do I move needle clip position? It is in the 2nd position.

Thx

I have exactly the same setup except I still have the stock 168 main. Mine is running like crap. Did you get any good advice?

i see nothing about it that would require jetting changes assuming it was running correctly before.
