Don't see anything like this. Just number or letter, no number X then number. That sucks... The lobes are greater than stock new cams. (F3) but when taking in the centers, they maintain same lift. (maybe 179X2)
I will check with degree wheel. Hopefully today.
This stuff came from HRC, wondering if they didn't stamp it cuz they were trying to cheat? I got the crank with the lot, although it was not in the block yet, same with the oversized pistons. Spring and retainers/valves were forsure changed.
Don't know how megacycle did things back in 92. The crank is engraved, and numbered but a bit more obvious with the weight reduction, and polishing.
The cams have color stamps/dots on them. Yellow and orange. I could send a pic.
Great idea with bicycle spoke!!
The guy I bought the stuff off of back in 98 was bang on with the other stuff I bought. Makes me wonder with these cams. After seeing your pic and the number and all.
With your experiance, adjusting with slotted sprockets to the correct lobe centers, were they initially off, from stock?
It's really cold here today (-32C)
Try to check opening and closing, then I should know. Just have to get the dial indicator on the bucket.
Thanks for your help!!
