I have an interesting challenge. I acquired a race RC51 over the winter; cheap and with some of the good bits, at least in theory. Or at least -- better bits than I am a rider, which isn't saying too much. Forks are at least in theory worked by Kyle Racing; not sure exactly when, however, or what weight they were set for and so on. Again, in theory I have the Ohlins 20mm kit in there, but haven't pulled it apart to check.
The local track has a couple of good old transitions over the edge of a banked oval. I'm ending up bottom the forks going over these; not hard, but enough that the zip-tie slider is all the way down. Did the obvious first, and had it re-sprung for my weight (200lbs without gear, these days, having porked up). Still bottoming, though i'm not getting to much from the front end on it.
The local guy had some 1.0's put in there. Same as stock, but again -- no idea what weight they were set for, and the new springs are apparently stiffer than the rest. Spacers were pretty beat up, so I figure I might need to replace those to get enough pre-load. Fresh oil at the start of the year, so not that.
Any other ideas? Appreciate the advice -- though I know the RIGHT answer (yank 'em, send 'em back to Kyle, get 'em sorted) I'm trying to do this on the cheap as an RC51 isn't exactly a dynamite bike for a small, rough, tight track. FUN -- but certainly not the fastest, so don't want to sink a tonne of money into it.
