Hi all.
I have recently brought a motocross sidecar outfit with a Tr1 engine in it.I brought this bike from Finland and I am in the uk.The bike is running really badly ,which I think is fuel related.The bike is fitted with 38mm Mikunis with 52 slow jets 200 mains which may have been drilled bigger and K and N airfilters ,it also has small car silencers.It has been used with 36 dellortoes but I dont have these.
The question is are the 38 Mikuni to big?And what size jets should I start with?
Or I have 34 mm dellorto carbs of a big xs yam motor are these to small?
The carbs are roundslide ones.
