I seem to remember being told that if you fit a 1170 kit to a J series engine the pistons can hit the valves. Does anyone know about this or can I continue on fitting the J head to a GPz 1100 b1 including cams (b1)

Only a problem if you fit oversize valves. As I found out :oops:

Mark.

I think the UniTrak head had different valve angles, so need's different Wiseco's.
Maybe that's what was in the 'back of your mind'?
