i just bought a nova rossi rex bf2000 for my jammin crt and been having a problem with it. I probably have 1/2 gallon of fuel through it so i know its not fully broken in yet. I took it too the races and at practice I had a 14t clutch bell on it and it ran fine and temped at 220, then like 2 minutes later after i temped it it just fell on its face. when i gave it full throttle the car only ran like i was giving it 1/2 throttle. I brought it in and it temped at 275. So i took it in and richened it like 1/2 turn and put a 13t on it. I ran the 6 min qualifying and it ran fine the whole time and temped at like 218. Then i ran the 10 min main and it ran fine for the first 8 mins then it fell on its face again and did the same thing. I had to roll most of the jumps cause it didnt have enough power to clear the jumps it was easily clearing before. I brought it in and it temped again at 275. I dont understand how it could run fine and temp fine for 5+ mins then all of a sudden go to crap. help please.

I can't really help you, but I just had similar issues with a novarossi r21bf 6 port today at the track in my kyosho mp 7.5...[X(]
