says 0.002” inlet, 0.004” exhaust, for E3134 and E3225 cams.
Yes set inlet on one cylinder when inlet on other cylinder is fully open. That must be what the manual
0.004” is 1/8 of a turn on the adjuster. 0.002” is a clearance that you can just feel and rattle the rocker up and down a little bit. Should feel smaller than 0.004”!
Having said that, 0.004” inlet and 0.006 exhaust was recommended by American importers.
Having said that (!), my iron head T110 with E3134 cams and big valves runs much better with 0.008” clearances inlet and exhaust.
