Just about to fit a 28mm phbh Dellorto to my stage 4 tuned GP200, i have a 42mm Clubman exhaust fitted and i'm needing some advice with regards to what are the best settings etc for jet's and set up etc.
there should be loads of members with similar set ups around..dump the 28 and sling on a 30mm a few set up up for that.. or you could get it dynoed..?? you know its spot on then..
Ricspeed, gone but never forgotten RIP my friend #59
Scooterotica dyno centre (Housed in Sean Brady Scooters) in Ripon is not to far from the boro is it..good service..(but I would say that cause ive used it)
