Hi there,
I know this isn't the motorcycle group, but I am looking for some general info on how to tune the carbs on my 79 Honda CM400 Twin. 395CC engine, 5 spd trannie.
I have searched the net up and down to no avail. I think my only option will be to break down and try and find a manual at a decent price. So far no luck on EBay.... There is a Clymer one, but I wouuld prefer an actual Honda manual.
So what I am looking for is
A) Advice on how to tune up the carbs on this bike OR
B) Link to a website that shows diagrams and a step by step procedure on how to do this.
The current symptoms include:
- Brown smoke coming from the exhaust, indicating that the bike is overfuelling and running very rich.
- Intermittently runs on one cylinder, indicating overfueling and fouling of one cylinder.
- Gas occasional pours out of the overflow of both carbs, indicating a problem with the floats or the fuel shut off valve.
Thanks for your input.
