jeff,

so what do you have to do to the 101's to keep from burning pistons. for pulling the piston bosses out of the pistons. alot of people are blowing them up around here

Chris the guys that are buring Pistons & Destroying the piston skirts are running 14 percent oil & dont know how to handle the engine. Busted piston skirts are usually MONO Stuff. STUFFING a Nitro engine @ Full speed is NOT GOOD..... Believe me I have stuffed many piccos & killed the skirt & piston pin. the Rs101 wants 19-20 percent oil. on 60 percent nitro. If they are altering the intake timing & tuning by ear they are too lean. If they are too big on head volume & tuning by ear they are too lean. If the pipe is too big or too long & tuning by ear on a 3rd channel they are too lean. These engines run best on a boris flow meter reading of 38-40 you should be able to clean the motor out by ear on these numbers. if they check there needle on a clean run & find they are way above these flow numbers the engine parts, timing, pipe,fuel,volume, squish, Are out of Balance..... or the boat is set up WRONG........ I`am running 60-65 percent Nitro w 20 percent KLOTZ oil in my RS101`s & DO NOT have Piston problems........ps It takes 11 tanks of 24-25 oz per to break these bad boys in too.......... They need to stay rich & keep the piston speeds down untill after 10-11 tanks.

Agreed joe 20 % oil all the way always have to have good luburcation for a motor to stay alive!!
