i recently got a 66cc kit and i installed everything to the book, after i go about 4 miles the spark plug is glowing hot and it feels like the bike is losing power, bogging out. any suggestions?
Do not ride the bike when the spark plug is glowing!
How many miles did you ride it like that?
Did you take the plug out and look at it?
what is the color of the porcelain? White?
Is the spark plug damaged? cracked?
Is it the original Chinese spark plug?
Is the spark plug loose? like the threads are messed up?
Try using a new plug like an NGK?
Or your mixture is running so lean that you are about to burn a hole in your piston.
Do you have massive air leaks?
Does the motor idle?
What setting is the clip on the needle in the carb?
Does full choking the idling motor make it stall quickly?
how about some pics?
Gas bike seems to like to blame their customers for everything
and they know very little about these motors. Good Luck!
I forgot to ask ya what oil ratio mix you are running?
PS : No insults intended, just a hella lot of questions.
