With a br6es plug in there and it would run! Come on please? If I did not know better and ran out to the garage,buried my slide stop until it idled(john stu does!) put the devils plug in(many who ride trails believe this is the ticket!) ran the mix at 52:1(same theory)That said,my bike would be in the trash pile after running for 20 minutes without trans fluid!UNBELIEVABLE,but true!In any 2t owners manual I have ever seen,I am guessing 10-12,of mine THAT NO 2T MX BIKE's MANUAL or at the RACE TRACK HAS THE IDLE SET! IT GIVES YOU BETTER THROTTLE RESPONSE! Rule out mechanical issues,jet your bike,set your suspension and ride!
