Have you ever riden in the sand befor. did you fill it up when there was sand by the gas cap if so there sand in the piston mine has it in it to theres a craking sound whn you get into the rpm it scratchs the piston up i need to get that fixed pretty soon.reply back asap

 

The jetting or pin clip position would be my first guess as far as the black plug, however, the clacking noise could be a piston slap which would indicate a worn piston or wrist pin. How long have you been on your current top end (piston, wrist pin, rings, & gaskets)?

 

i was thinging my piston would be worn i ride hard core alot of jumping only 3 1/2 feet but and riding in the sand will do it to well i guess i will buy a piston or a newer gasket.What are better the t-5 for a blaster or a bill's pipe.

Mine was not enough tight and on one wire I have to redo the soldering and now it run great ,no noise.

Before trying another coil check the resistance between the wire that go to this coil and the ground . I had 0 at the beginning and when i shacked the coil it always went up and down . At the end i now have 250 ohm. Try to check the soldering on the coil and if the coil is not enough tightened .


My english is very bad ....
