Hi all:

I have the cb360 started and He idles perfectly. Twist the throttle, however, and there is no response. I even pulled the throttle at the carbs and no, no response. These are the stock cv carbs. So why won't the bike rev? Everything elsenis perfect...

--Cheers, chris

have you already confirmed that the engine's and some basic vitals are ok?

1) valve adjustement

2) good compression

3) ignition and timing properly adjusted

4) good non-fouled plugs

5) adequate fuel delivery indicating no restrictions from the fuel tank to the carb float bowls

6) no vacuum leaks

have you confirmed the carbs are indeed clean, all passages.... especially those tiny ones are clean and clear?

then do you know the carb diaphragms are indeed good?

blow into the hole in the bell mouth, which leads to the diaphragm chamber

this should lift the slide

or if when you open the throttle

assuming you have pod filters or velocity stacks

you should be able to see the slides move upwards

and just because they move upwards SOME

doesn't mean a diaphragm is 100% good

good luck

it was a combiniation of the diaphram not seating and the ignition being to far advanced. It's fine now. Many thanks gents.
