bottem end rebuild pre-lube?
kaw rider:
It depends on your riding demand. A guy running his motor with alot of tire up a sand hill verus a guy cruising around his local riding spot will vary. The real way to do it is to pull your reed cage after riding and put a bore camera down the crankcase and look to see how much oil is down there or feel how much oil film is on the crank and rod. With most of the 250 and 500 i build for track use i'm at 20:1-24:1 with any castor oil out there or 32:1 with synethic.

OK, thanks for your input sir! :-D
Aren't you concerned with the gumming up of the KIPS valves with castor based oils? Just curious.
kaw rider:
i just put a motor together for a customer and it had 20 hours on it since last rebuild and the powervalve add alittle soft carbon on it and looked good. Jetting is key to getting no gumming up.
