Hi there
I have this old grid.
I was wondering,
I got new valve guides, and a new exhaust valve. Is there a clearance the exhaust valve needs to be reamed to??
Ps the bike has an m20 frame!!

my exhaust valve jammed open

Hi Maxwell....0035" should be OK..Another point to note is that some of the rocker feed banjo bolts have very small holes (the 'cross drilled' hole). I drill these out to .040" (1mm) which increases the oil supply...Ian
