Where to order and what is the best high compression racing head to get? (66cc)

you can put the thread on the plug then screw it in the hole, then unscrew the plug. just put red loctite on the insert before installing in the head. take the plug out so it doesnt get loctited in. theres you tube videos on how to do it. maybe not on a motorized bike but the application is the same. search helicoil spark plug

ok thank you for helping with this i was so disappointed when i thought i had to replace the entire head when its still new specially after all the other problems iv had with this kit cause that company is a dirt bag and yea im not gonna go on about that... i did make a thread about what happened warning about that bike company and not to buy from them though... kingsmotorbikes.com and gasbike.net avoid them like the plague i had to open better business berau claims on th em and everything... they didn't even respond to them so they have bad reputation now

You also have to be very fast at putting the heli-coil in with lock-tite on it, it sets up pretty fast.
