In my final project I plan on running wrapped headers and straight pipes with washers to create some backpressure. I will be replacing the carbs with either Mikuni VM32's or Keihen CR33's. The Keihens are way more money by about $225. I have always been leaning toward the Mikuni but wanted to get some opinions and experience from here. Once again fresh rebuild with standard size pistons, pod style filters, and straight pipes with washers welded in for backpressure on a 1970 Honda CB450. The only big difference I could figure out besides the 1mm was the fact that the Keihens have a connecting rail and utilize a single style cable. Will either one benefit me more than the other? Thanks.

IMHO, either is overkill for the street with a stock engine.........

The only plus to running the Mikunis (on a stock engine) would be ease of changing jets and availability of parts. Stock 450 carbs are already pretty easy to change out jets on.. You can locate parts for them too but not as easily as the modern Mikunis.
