I have a few track days comming up and want to use my 748 that i purchased a few days ago, problem is i need to know if the valve clearance is ok? or will the engine blow up, they are on the loose side so i'm guessing that is good compared to too tight,
here are the specs


Vertical .........................................

exh op .007 closing .004 and op .008 closing .004

intake op .005 closing .0045 and op .005 closing .0065


horizontal ...............................

exh op .005 closing .001 and op .006 closing .0055

intake op .0055 closing .0045 and .0055 closing .0045


thanks

My 748 manual gives

metric (mm)/Imperial (inch)

Intake open 0.13 - 0.18/0.0055 - 0.0063
Exhaust Open 0.18 - 0.23/0.0075 - 0.0082
Intake Close 0.13 - 0.18/0.0055 - 0.0063
Exhaust close 0.08 - 0.13/0.0075 - 0.0082

So exhaust opening looks a bit tight on the horizontal
