A solid model: FL
check pin is "stepped" in ascending increments up to .875 diameter max. Rocker shaft is .874 diameter. The cast iron base was milled clean on the inside surface, removing(about .0015-.002 of material) just cleaning it up. You only need to remove material from the iron base, not the bronze top plate. The blocks are bolted together and honed until our check pin just fits into both sides or (.875). The steps on the pin tell you when you're "gettin' close" to the proper diameter. Now the bores have a nice cross-hatch, and are round again - returning to factory specs. and clearances.
(PS. I think Hawbaker made the check pin?)

Goldsmith could really wind up those Harley KRs back-in-the-day. Dirt tracks or pavement - he was a threat to win on most any type of track. Paul always appears to be a bit taller, more lanky than the typical motorcycle racer. The taller riders impress me (like Ricky Graham), since usually it's the "stocky-jockey" build type that makes a good flat-tracker or road racer. Paul maybe had to work that much harder - making him one of the all-time greats of the sport.

Moral of this story: I should stick to work & drink Coca Cola.
Paul Cox acquired a couple of these for his latest bike build. I noticed a case at the Cedar Rapids swap meet that had "Little John" cast right in the case, but I didn't know what it was. I saw this advertisement in one of my old, magazines - wouldn't you just know it ?
