Ultra-Small Boring Head
#33
Minimum bore on all boring heads is 0.000 Darren as long as the head itself does not enter the work. That was not the problem. I could not get a 2 inch diameter Boring head to go into the crankcase far enough to do what needed to be done. This one at 1.5 inches has .100 clearance when in position. Of course, this is on paper and has not been tried you, but I have high hopes for this one. A smaller version would be even better.

I will try to scan and post the front cam retainer so it becomes clearer for you. The real problem is that the front and rear cam retainers are 4.5 inches apart and I found it better to fit them at the same time. As stated this requires breaking the assembly down to remove the necessary material each time.
