modded motors
 

I looking for a sirio modded 12 and was wondering who does the best work and price. I've ben reading alot about the richey motors.but still doen't know much about them like are the made from scratch or are the a hand modded name brand.also when they do come out probably won't be able to get one. I've looked at the jps,rodys,novamax and the cost is kinda up there and the reviews haven't been steller. please help with options I'm also trying to find a m speed motor to
thanks
