... take what you read to be 100% fact and truth..
Is that being recorded/advertised via the crankshaft, or rear wheel?Scott
As far as Page 46: Jims 131 Crate Motor.. take a BIG red marker and draw an X through the page,,
My only comment on "Race Motors" is they usually are just that. In the old days a Honda race motor was prepped just "right" when just past the finish line it was a piece of junk. They were built and tuned to run 1 race at the max and not a lap more. Pop's Yoshimora built his stuff the same way. Expecting a "Race Motor" to go 100,000 miles is wishful thinking. Kinda like wanting a Newbie Dresser Dude with a 11:1 compression build to pull a trailer and wife in 100 degree temps on vacation and not ping or overheat. Not standing up for the Jim's 131" or any other motor just stating my opinion. Sorry you got a piece of junk sitting around.
As far as issues, I replaced the original lifters at 300 miles (noisy) and just to be safe, I freshen them every 12,000 miles.
DJWhat is the definition of "freshen?"Is that replacement or what? SBB
All the charts in the SE catalogs are rear wheel chassis dyno numbers.Jerry
I replace them. My concern is with the load that the tappet rollers are subjected to with the aggressive valve trains, over the long haul. When one of those bad boys soils the nest, it can be a pretty big deal.
