Hes as patient as they get when I needed a new engine parts that were hard to locate or if I had to wait for postage from across the world I got another whole engine

Alx offered me the right crank for €250 shipped the other day an that comes with the needle bearing, the gidgeon pin comes with the head kit.
I honestly don't understand why you are struggling mate as the case is designed around off the shelf parts.?

I cannot use that crank because it has a 10mm grudgeon pin so it won't fit the Piston on top of that I don't have 250, also is that in euro? If so that's even more in USD. But he does have a great deal for it.

How is it? Like power and reliablity wise. Haven't found really anything on any Athena kit. Ill see about maybe just maybe I can swap my piston and get the crank. But don't count on it. ? Hopefully I can make it happen

Ran well with the Athena kit on, plenty of power and over 17k rpm.

Soon as the mallossi kit came along I just jumped on it because it was the new best thing?
