Before I do the cam mod on my YFZ450 tommarow... I need to know which bolts have to be tightened to 7.5 ft. lbs???? Just the cam journal bolts and the 2 alen head bolts...... or just the cam journal bolts??? How would you tighten the two allen head bolts to 7.5 ft. lbs??? I know I can do the actual bolts on the cam journals...... but how can you torque an alen head..... do I have to go out and buy an adaptor for my torque wrench or something???? Thanx in advanced!!
