GPR Jetting

Post by BigDaddy SnakeOiler »

Anyone here have the GPR exhaust? Any advice on jetting with a Ramair?

I have one, but I also have a 22mm carb. When I had the stock 18mm carb I remember having to go up a few on the main and idle, but the Stella uses a different idle jet than a standard Keihin PB. The standard PB idle jets caused erratic idle and bogging/stalling off idle. Others have had no problem using them, though.
