Ok so I just bought the bike a week ago, it came with a full yoshimura rs-2 exhaust, 3x3 mod, and a twin air filter.
the bike was backfiring a decent amount so I pulled the spark plug to check it and it was a little lean based off that.
so I then ordered a dynojet kit and not paying attention got a stage one kit, so I then sourced a 160 main and 25 pilot locally to make up my jet kit.
pulled the carb apart and dun dun it's jetted already with:
different needle, looks like the new dynojet with 6 spaces
and the air fuel screw replaced
so what I did is put in all the new stuff:
New needle, on the 3rd from the top
air fuel screw out 3 turns
bike well only start full choke, stumbles on half and won't start or run with out the choke. off I try to give it gas it dies no matter where the choke is.
the other thing off the 160 main has a bigger head on it but it fit no problem in the little plastic clip thing.
any help, oh I'm at sea level.....0 altitude.
