I have 2 CRF230f's, I have just installed new jets to one of the bikes and noticed it didn't have the plastic baffle plate around the main jet. I checked the other bike and it had the baffle plate which I put into the other bike, it doesn't seem to make any difference to that bike but the bike I removed it from now runs rough on full throttle.
I cant find the part number for it and wondered if anybody knows what it does and what is its part number.
Many thanks.
