| head kit & spark trouble
hi guys i thought i'd let ya know about my bike
and get you thoughts and comments...
i bought a 3D ported headkit and engine.. fitted it up
to my bike and it ran fantastic for a good 6 months
until the spark plug kept coming out..
i got the dome re threaded (helicoil)
worked great after that.. till i put in a ngk spark plug...
the bike ran for about five minutes and then would not
want to run.. it was acting like the jet was blocked
so i cleaned out the carb and tried again..
still did not work.. went over the whole bike including
the coil and anything it could be...
the last thing i tried was the plug again.. i took it out and
realised the plug tip was bent down and getting a very poor
spark...
i put back in the chinese plug that came with the kit.. and
the bike ran great again...
in the end i realised the ngk plug thread must have been a
slight bit longer as it looked like the plug was hitting the piston
and bending the plug tip...i have come to the conclusion that
when they did the helicoil they must put in a touch lower that
the original thread so it looks like that i can only run the chinese
plug or maybe put the ngk plug in with 2 spring washers from the plug...
what do you guys think ?
