Over the last weekend I installed my Hi-velocity ported heads with Singh Grooves, Wiseco HC pistons and new car lifters suggested here. The bike runs great and is noticeably faster to me.

I pumped up the lifters with SeaFoam before installation and did the bleed-down described in the Tech section and Clymer's service manual. I used a break-in grease on all new parts.

I installed 10W-40 grade (non-energy conserving) Quaker State oil for the break-in period with a new filter.

I went to buy a dial gauge to adjust the rocker arm fingers and could not find one that measures into the 1000ths (few places carry them). Sears has one that measures to the 100ths for $35 and I did not want to go with that one.

I adjusted the rocker arms by hand using a 4mm open-end wrench and feeling the adjustment screw as it touched the valve stem, then tightening the lock nut with the 10mm box end.

I can't seem to get thing as quiet as before. I suppose that even a slight turn on the adjustment screw will bring the finger up a few 1000ths and cause clicking. What is the best way for me to proceed?

Thanks,
Ray
