Thanks.. I didn't knew that! Most reactions on the original bike or when I started with the build were negative. Nice to hear something positive about the original CM400 I really like the way the original frame bents over the engine. Form behind it looks very small, and with two carbs and nice open filters on it I believe it will look great!
I already posted a question on the engine part of this site. Maybe some who will read this project can help me with my carbs.
I want to upgrade my Keihin (vacuum) carbs and bought (maybe to quick) some Mikuni VM30's.
I read on different sites that the Mikuni VM30 was the best upgrade for a 400 cc Honda and the VM32 for 500cc. When I tried to fit them I saw the intake and Keihin carbs are 36 mm. Large for a 400cc Honda I believe, even for my 450cc with flow optimized.
Some people tell me to place the VM30 by making a cone-shape tube between the intake en carb. Others tell me to get some 36mm VM36 and make a custom exhaust. Maybe its in between. Who knows? ???
Hi, today I placed the engine to see how much the front forks would react. Also tried the original bend exhaust pipes and megaton dempers. I like the classic look with the pipes below. Although I'm thinking of custum pipes and gp-style dempers (vertical).
Hi guys, we've been sketching up some next steps. During the build I began to see the beauty of stainless steel. And decided to make some changes. Instead of going all black, we're going to combine red, black and stainless steel. Some details are in gold, like the front brake, some screws on the carbs and the chain. The tank and back-end will be red. The carbs, the sides of the cilinder and carter won't be painted and the exhausts, headlight case (gone make one) and most of the screws will be stainless steel.
After doing research, reading forums, speaking with former eighties racers I've decided to compare the Mikuni 30 mm carbs with the original Keihin 36 mm. I've found a dutch carbs specialist, wo will fine-tune the carbs on our set-up: 400 engine and head (+ 7 CFM/+ compression), 450 cilinder. We're going to make a pipe going from 30 mm to 36 mm to optimize the flow using the Mikuni's. And compare them in a test environment. I'm curious what the effect of the Mikuni VM30 will be.
