Hello guys, I have an question to all members that has knowledge about porting.
I have bought a blaster about 2 month ago,and it's stock. The seller has give me a second motor with a +4 hot rods crank.
Furthermore, he gave me a machined cylinder. He said I just have to have it re-drilled and then I can drive it with a 2mm spacer under the cylinder. Look at the pictures. The exhaust was made well in my opinion, two additional channels these are 1.5mm higher than the original exhaust timing. That also fits so far I think. At the entrance I am unsure of the boost port, so the middle channel has been widened very large. This is 1.5mm higher than the overflow. Furthermore, too high was drilled there. What do you say to the cylinder? Should I get it re-drilled and just try it out? So exhaust is a fmf fatty exhaust carburetor is a 34mm Bing on it. Just don't want to have the cylinder drilled for free.
