inferno mp-7.5 running problems
 

could i get some advice on why my inferno stalls or cuts out once it gets up to temperature. i beleive it may loose compression as the piston sleeve heats up. the enigine is 3 years old and i have had alot of fun with it. once it gets warmer it is really week on the bottom end. if u need any more info i will give u more, juts trying to keep it simple right now.

Hi,

I guess you probably need new parts or new engine. New parts will be ball bearings and conrod. Leave the cylinder and piston as old.

If you want to check compression, it is simply. Take off the exhaust and header, take the engine out. The engine should have a flywheel on. Hold the engine by just the flywheel for up to 10 seconds. The engine should drop on either side and stay, if it doesn't stay and heatsink flips downwards, then compression does not exist. You will need new cylinder and piston also. Of course you will need to break in engine again.

Thx
