You have to be very carefull not to leave any of the shavings in the motor.I pack the cutter with grease and line the bore with grease too so you can just drop the piston and wipe the cylinder clean.Also make sure you cut slowly until you get the feel for it and my preference is ussing a valve shim to check cutting depth.

Yes you do have to remove the head each time, but you actually only use 2 bolts so it's no big deal. It's a bit slow, but this is an area that you don't want to rush.

I do have an old head gasket if you need one. PM me. It' yours for just shipping cost.

FWIW- If you set the cutting height without a gasket a used gasket isn't needed. Just clean the cylinder real good. The shavings are quite large and an easy clean up IMHO.


I'll have MTI G1 results very soon. Stay tuned!!!!!!!!!
