Im trying to tune a Yamaha 250cc 2 stroke I got it to start and idle but it dies at 1/8 throttle and wont rev smoothly its has the wrong main jet would that cause a problem but i can get it to redline and and it runs and revs fine in the power band.
its a 30 mm mikuni with a 35 or 45 slow jet 250 main
could it be the timing but it starts easy first or second kick
