DMC 145cc Kitaco Conversion
By Jerry Matta
Well this is the kit, $1150 with of horsepower. I got from Ryan at MotoXworks in Costa Mesa, California. He hooked me for a little better deal. Basically, every dealer has to go through Classic Honda so it's kinda hard to get killer deals on any Kitaco stuff. But Ryan did his best, basically his cost plus shipping. The one note I would say about the motor is the tiny valves stems which is the weak link of the kit. On the plus side, it makes the rev quicker and hit harder, but on the bad side the valves will break make the whole kit junk and your pocket book will be a whole more empty. Personally I don't feel the trade off is worth it. For two reasons: One, it's expensive to replace and two, I hate taken apart motors. I have a separate article on this about grenading this kit. But how is this on the track? Combined with a Mikuni 26mm Kitaco carb the motor feels like a mini CRF250, except it revs better and doesn't need to be short shifted, so I guess it's better than a 250f. The difference between a good running 120 and this motor is night and day. It hits, pulls, and revs. Everything you could want in a motor. So what's on the bike? A Kitaco 26mm Mikuni car, DMC 4 step megaphone exhaust, CRF450 twin piston front caliper with steel braided line, XR400 oil cooler, IMS pegs, gold Excels, CRF150r mini high bars, and a multi-position top clamp. All this is riding on Fineline Suspension. Fineline is now located in Utah.
Brand new in boxes. I'm a happy camper. The crank is sweet, and seems lighter, but I didn't weigh it. This is the heart and soul of the kit. Super light valves and a exhaust port the goes contrary to what how most people think of flow and power work in a motor. However, Dave Miller have been talking about this for years. Our old 120 piston vs. the super light 57mm piston. Just check out the difference. This is what throws most people for a loop - - the tiny exhaust port. Nothing like Japanese directions. A nice view of the height difference. This is the hole that needs to be drilled out to 2mm for the High flow oil pump.
