I got pro curcuit pipes and a pro flow kit. I live near sea level. i need to know how to jet my machine. thanx

 

My guess, start at 260 or 270 mains and work your way down if you start fowling plugs. But thats a ball park guess.

If you're too rich the motor will be way underpowered.

To lean and it will be erratic on acceleration.

Remember lean is mean.

 

Thanx for the help. I am interested in aftermarket reed valves. how did your boysen valves work for you? It is a toss up for boysen, duncan, or vforce deltas.

 

If I had it to do over again I'd probably go with the DeltaVs, I hear really good things about them.

I can't say I can tell you how much the Boyseen Rads help, as I upgraded everything at once.
