His bikes run horribly. I have been searching like crazy to find the answers, but I'm on a short time table. I have to order parts tomorrow morning so they can make it to my friend who is coming down to Nicaragua.
Now here's the problem with the bike:
He has a procircuit t4 exhaust and pipe on it. He doesn't know if it was rejetted. As far as I know no free mods were done to it, but I really am not experience with these bikes.
It's a bear to start cold, and when it runs it pops and back fires like crazy, and has no throttle response. To me it sounds like a pilot jet/fuel screw adjustment. Also to make matters worse the fuel screw broke and he's got some sort of plug? glued/siliconed in.
I'm trying to help him, he was last years top endure rider in Nicaragua, unfortunately the only mechanic he has near him is horrible. And being in Nicaragua he can't get parts.
So what do you recommend. I want to make it run like it should. JD jetting kit? What size jets? Any suggestions for a fuel mixture screw? Free mods? He was worried that the free mods cause engine damage. Any validity to that? Bestow upon me the wisdom and guidance, and really quickly too!
