just getting my 250R outta mothballs, had the lower end completly rebuilt (bearings, seals, crank & a hot rod) and i did the top end myself (.060 over)

i've got 12.8 fl oz's of bel~ray H1R synthetic racing oil...
whats a good break in ratio to run & for how long? then switch to??



sorry for the stupid question, havent ran this thing in 15 years (i shattered my right collar bone on it) & i bought it new



















help me......... just, help me;)

Everyone will have a different theory, what i do is 30:1 for the first tank, then 40:1 thereafter, ive never had a problem doing this. Broke you collar bone huh, that dont sound like much fun, hope all goes well.
