I can't keep the headgasket from blowing. After the first one blew using the supplied kit and torqueing 27lbs after 30 minutes breaking in at half throttle. Gasket blew at 3/4 hard throttle I looked at the Niche jug. It wasn't flat. The cylinder sat down just a hair below the rest of the jug. I thought this caused my first headgasket to go, so I got some 220/320 sand paper on a flat surface and after 30 minutes got the cylinder flat with rest of the jug. Then sanded surface of head to make sure it was flat too.
Resembled engine and rode for 20 minutes no problem till I started doing wide open throttle. Then the headgasket popped again. I am going to tear down again. I am so passed off.
The kit had thicker bolts than stock. I find it odd that everything works fine till I rev up the engine higher in the rpms and thats when the headgasket gives out.
