Just a note for you guys that want to mod a TR r-SPEC- if your motor man hasn't spent a LOT of time with the TR R-spec don't count on them being able to make a lot of extra power. I've learned from Ron that these motors don't respond to the "normal" mods like the italian motors. The torque curve on these motors is lower and they need different porting. I'm not sure if Ron's motor guy is willing to do work for other people but we can find out. If you would like to ask him yourself email Ron from www.kinetixrc.com .

Further info- if you are running typically short tracks then don't waste your money- the motor is awesome down low. It has TONS of low and mid range power. The only place it needs any work is high RPM. I'm VERY happy with the motor and wouldn't even think about buying something else.

one last note- for you guys that think a nitro motor needs all this bullshit break-in procedures with rich idle and crap... PLEASE. I don't have time to go into the specifics of why a race motor shouldn't be treated like that (which I can do later) but just start the motor, watch the temps, tune the idle, then ease into the high speed settings. Keep the racing temps around 220-230 the first few runs. DO NOT run the motor so rich it runs like crap- that HURTS a race motor. DO use a heat gun o to heat the head and block before you start it the first time. I've already run almost a half gallon of O'Donnell 30% through my motor and it still has so much compression it gets stuck where the starter box can't spin it- I have to back it up with my fingers to get it inbetween compression strokes.
