Default Re: Another Build from an abandon in the park bike

Do you think this barrel has missed a machining operation? To me it looks like they forgot to mill the top, see the rounded over edge! I put it on the block and put the piston to the top and it fall's short. You can see I have been carving on the ports. I widened the transfer and enlarged the exhaust and intake. Well, I don't know what to think about the barrel I will try and put it on the mill and mill the top off. Have fun, Dave

PS: The cylinder I used on the other engine was clean shave'n and the piston was at top. See the piston in the other pic how low the pin location is, (short rod). Also look and the size of the cut outs for the transfer ports, I removed a lot of metal from that barrel (one on top)
