i rebuilt my topend a month ago and have only rode it for about an hour total so far because ive had so many problems with it. i sent my cylinders out to herr jugs racing and got them bored and honed with the piston kit. i put it all back together and it started right up but smoked A LOT. i thought it just had a bad head gasket so i ordered a new one and put it on, and it still smokes A LOT. i decided to check the compression and it did not go past 107PSI. i read that stock is usually 120-130 and anything with 110 or lower needs a rebuild. why is my compression so low? its freshly rebuilt. it starts up always on the 1-3rd kick. also my spark plugs were pretty wet when i checked them. the motor is completely stock besides being bored over to the next size. anyone know whats going on?

I think there's a pinned link in how tos on leakdown testers. U can make your own for about 20 bucks. I used the link to make mine and its a invaluable tool to have for two strokes. 6psi for 6 min is the goal. The seals r on either end of the crank but there's no sense pulling ur clutch cover and flywheel before u know if you have a leak or not cuz u gotta split the cases to replace seals anyway. Do the leakdown first it can eliminate a lot.

The reason I rebuilt the motor was because I

Bought it as a roller with the motor out and the motor had the top end pulled off. The kid just said it needed a new top end rebuild . Breakin it in I started it up and let it idle til warm and

Shut it off to cool and repeated that a few times then on the 5th time after warming up I rode it very slowly not giving it much gas for 10 mins then let it cool and repeated that process babyin it.
