850 camshaft choice
Hi all, I have to replace my 4S cam, what with though, STD or 4S?
The bike was built as a MH Replica PR with MH big valve head, 4S, 10-1 piston & Rita EI with 4S advance curve.
Now, it’s got FullAuto head, std pistons, 4S.
I’m quite happy with the cam, but not sure if std or PW3 would be better?
TIA
Paul
