TECH: KK Cylinders

I've had these awhile.  They were rusted, needed a bore job, a base was broken, and cooling fins were missing.  One has now been sleeved.  The fins repaired.  The base repaired.  They have new guides and new valves.  The rusty, pitted valve seats have been ground and lapped. 

That plastic bag has the Eastern Motorcycle Parts spring spacers I'll use to set up the valve springs for a set of KK cams I have collected.  These are nice spacers to use, since they have a small lip on top that fits into the valve spring and helps center it on the guide, and hold it in place.  I'll measure my installed spring height, then subtract my cam lift (and .070).  Then I'll subtract the length of my spring at coil bind.  This will leave me with the proper length to make my spacer/shim for that particular valve.  I used my Valve Spring Tester to check my springs, and I'll run the 2 strongest on the exhaust valves.
