Does this sound right for a 06 YFZ to be tight on the intake? two are fine but one i can only get a .102 shim in.
they are stgII cams with the cam mod.

Sorry that people weren't more helpful over there (except me). I know there is a shim calculator (either here or on that site too), but I'm not sure where. Also, I can chec my manual and try to get back to you tomarrow.

Did you get this done yet?

Mine is an 04 and the specs are 0.10-0.15 mm (0.0039-0.0059 in) on the intake and 0.20-0.25mm (0.0079-0.0098 in) on the exhaust as far as my manual say's anyway. Not sure if the 06 is different but I thought this might help. Good luck!
