ring end gap for wisecos?
anyone know?
i got my pistons and jugs back from local indy and instructions in wiseco kit doesn't say what the end gaps should be for both rings
from everywhere i've looked online, seems like it ought to be perfect at .015
formula is at .004 X each inch of bore, as i understand it according to Wiseco
therefore, at .020 over bore (3.518) X .004 = 0.014072 (gap therefore can't be below .014, so would have to come in at .015
can anyone confirm?

ah!...thanks john.... i'm sure my indy checked them anyway, but can't hurt to get in there with a second set of eyes
now, breaking it in right would mean stay below 3Krpm for at least 2k miles?

I found this article about breaking in a new motor interesting

i've heard this before from other riders but never gave it much thought thinking that they were just adhering to some myth
apparently it's true, though
john, chime in here?

I did the same thing with my subaru (built 2.0L engine, headwork, cams, giant turbo, etc etc). did the 20min high-idle breakin (spec from Crower for the cams), took it down the road and immediately romped the crap out of it (at that point i was without the car for almost 4 months, couldnt wait anymore lol)
i'll do the same with the bike. Probably a 20-30mile ride to REALLY get everything warm, and flog it for all shes worth on the way home.
