all this 2 angle this, 3 angle that is all 4 stroke talk about valve jobs, not porting a good, professional port job should flow smoothly, no edges or angles, your buddy obviously doesnt know sh*t either, wtf ???
limin, take that sh*t outta your bike, and with the head off take that sh*t back to whoever did it and show him what you found, demand some type of itemized bill, with receipts for the parts he "claims" he bought for it, for a stroker crank, or if he rebuilt the crank...ask to see the reciepts for the rod and lower bearing, or from the shop who did it, and that you want a new head gasket, not your old, used, annealed one
or demand some type of refund, or you will run his name, shop, and shoddy work into the ground all over town and the internet
it's your right to demand to know exactly what was done to your motor
what did you pay for this nonsense anyway ????
