12 thousands is .012 which is less than 1/64th of a inch.I checked my math and its .120 thats like a 1/8". Check to see if it is .3mm that he was to mill off

Yes it is but 3mm is .120 thousands and sorry didn't see the .3mm at the first post.12 thousands is .012 which is less than 1/64th of a inch.
No Base gasket on the RF4 motor Orings inserted in the case around the base of the cly. sleeve their is a mark on the top cam chain gear. rotate the crank 6 times to line up set TDC stop bolt and install cams.Trivial, but INSURE the arrow on the piston is facing toward the front or exhaust side of engine or the valves will hit the piston...he probably needs to do a squish clearance test if he is sure the piston is oriented correctly
Timing of course could do this also...
Too thin of a base gasket can do this...
Thats about all I know and I have done all three at one time or another...please don't tell anyone... :lol: :lol: :lol: ...funny when I had too thin of a base gasket it wouldn't hit the valves until about 3000 rpm
When I had the piston on backwards (Not all of them are marked so it wasn't all stupidity just ignorance on my part) it would hit the valves at idle, but would start and rrun fine

You will have to degree in the cams and it should be fine.
He milled it 30,000ths witch is 2 1/2 times bigger.
