    Default running problems

    Can anybody help?? I have a 2001 Superjet - it will run flat out but won't run slowly (at 1/4 throttle). I have just fitted a Protec Mach 1 Exhaust, could this be the reason why? Also, which jet is which on the carburettor (stock carbs). Thanks.

    Default Re: running problems

    If You Install An Aftermarket Exhaust You Must Also Modify The Carburator. Pop Off Psi And Jetting Changes Are Required With This Type Of Modification. It Will Never Run Correctly Until These Changes Are Made. You Can Even Do Damage To The Engine If Ran Like This. Im Not Familiar With This Particular Pipe So Contact Pro Tec And Get The Recommended Jetting Changes For Your Application.
