I own a 92 RM 250. Its got a fresh plated cylinder, new top end, FMF head pipe, FMF silencer, boyesen rad valve w/carbon fiber dual stage reeds. Its got everything that I can think of or find to bolt on to the engine or intake to make more power. Ive read about the Answer Roost Boost, and the IKat spark amplifiers, but.......... Im a little leary about them. Mostly the Answer Roost Boost, if they were as good as Ive read about them why doesnt Answer still make it?? The IKat is just to damb expensive $189 bucks for something that just resembles a spark plug wire. Is there anything bolt on item that I can think of or find for my year, make, and, model. Is there anything else Im missing. I know its not all about the engine and horse power, but that is my concern at this time. Im working on getting the suspension too. Ive got a shock spring in the works for my weight, and same with the fork springs. Once again is there any other BOLT ON engine performance item that I could or should have for a 1992 RM 250?
