Just broke in my reedy this weekend, very impressed with it so far. Broke it in according to the manual, it ran 3 tanks through it on the box without needing to be restarted, let it cool, did 2 more tanks on the track, then off to race tuning. This motor is a beast in truggy. Its lacking alittle in top end power, but I think putting the 2035 pipe on it will wake that up. I broke it in with a 2050 os. Still have alittle to lean out on top, and just put the other shimm in it, so I'll report back after this weekend.
