David and his staff went up and above on customer service. They answered all my questions, communicated promptly and shipped quickly. I paired the 149 BBK with chimera intake, dhm s1 cam, speed pro cam sprocket, kitaco hv oil pump, kitaco 5 row oil cooler, 60% clutch springs, avail cam vent adapter, 14/37 gearing, yumanashi 4th bearing, pcx150 injector, and dhm flash. This thing rips now. Feels kinda like a real bike haha. I bought the koso 34mm throttle body.and intake, but am waiting for the ported head to get back in stock before i install it all...cant wait. Thanks DHM!
