Stihl 044 rebuild. Light porting. 

Pretty impressive save on that cylinder man

Thems is some good numbers

wrist pins appeared to be different heights? you should get more compression off the original ?

Because of the piston, you can raise the intake skirt .030 +/- .010.

Also another note . Just the way my brain works but I feel like if you could get a piston without windows I feel like you would gain alot of velocity through the transfers . Just my opinion but seems right in the way my brain works
