hey all just got into trials n jus got my new bike..now some dude that had it before me needed to replace carb parts, but the mechanic he had workin on it changed out the choke jet with plyers and striped the numbers off the end , im jus wondering if anyone has the bike or knows what the number jet is i need to be running, the dealer said thers millions of diff ones and without the number its guessing blind, he sent me one he thought would be best suited to my bike, but still doesnt idle down correctly , bike works fine and is ride able its jus annoying listenin to the idle when i grab the clutch, thanks for your time also my bike is a 1994 montesa cota 314r 250cc if im not mistaken ?
