i just put in a new piston about 3/4 of gallon ago. so that can't be the issue.
the motor was on it's second gallon when i started to run the gen 2 fuel from byron. the piston and sleeve were out at about the full gallon mark. a guy i know had a motor deal with race factor so he was able to replace the piston for, not the sleeve. don't ask about only the piston, just that it was just the piston. i will take what i can get for free if you know what i mean. i started running tq fuel since about the beginning of the first full gallon. have ran the motor great for the last gallon and a half on tq fuel. always using after run oil, watching temps and performance.
but this is something that many people from any forum have not seen, just seems odd to break in that particular spot
The same thing just happened to me today! I'm loosing faith in the GO. My 7 port just shit the pot after just over 1.5 gallons. Wouldn't start before the main. This is the second P/S/R id put through this POS. The first one tossed a wrist pin clip and chewed it up after just 2 gal. I'm pissed! I babied both of the damned things during break in using all the expert advise of all the gurus in the RC Tech Go thread. Spent hours heating it and breaking them in for a gallon. Pulled the break in shim after 1.25 gal. Only got one race out of the second P/S/R and now I have a GEN 5 7 port in the box still and I'm thinking about selling it before I put myself through more greif!
Think Racefactor will hook me up? What do I do?
