g2 that just quits

mncdriver · 08-25-2009, 08:43 PM

Please someone help me. have a 86 g2 that just quits after about 20 min. of run time. Seems to be when everything gets heat soaked. Had carb off and cleaned, needle and seat look fine. New spark plug and Igniter(200 bucks). could the coil be getting hot and giving up? any thoughts would be great.
thanks Mark

ok so today i drove it until it quit. just before it quit it started to back fire through the carb. pulled spark plug wire off and pluged it into 2nd plug that was grounded. showed to have good spark. put wire back to see if it would start. after spinning over for a few seconeds it started up and ran. then sounded like it was missing and shut off also back fired through the carb again. i hate to throw more parts at it for no reason. stumped

Try this....the negative battery cable bolts onto the starter/generator. Yamaha "pigtailed" a 18 gauge wire at the eye end terminal. Cut the electrical tape back and cut off the 18 gauge wire, put an eye end on it and reatatch the small wire to the starter post. Could be the connection is bad and if so, missed spark. Good luck dave

thanks for your help. i removed all the tape from the wires. Tracing them i found some wire exposed on that 18 guage wire. taped it up and tried it again. hopeing it was arcing to ground on the motor mount. same situation. it cut out after about 15 to 20 min. of run time. the connection looked good at the starter. should i still go ahead and splice a ring terminal on that wire? it really runs great for the 15/20 min. window.

I got it fixed I think. Found out when wiggeling wires I could make it cut out. I started tracing and wiggeling wires. There is a three wire conection next to the igniter. One of the pins was pushed back and not making a good connection. Fixed that and so far me and my sons have been riding all day and no issues.

thanks for the help.
