I've got a 1982 CX500C with just under 32k miles. I've got a slight lean-out condition at around 5,500 RPM when I'm just barely into the throttle. If I (1) give enough throttle to get a good accelerator pump squirt or (2) give the choke cable a pull of about 1/4" to 3/8", the engine pulls strong again. If I just stay barely tipped in to the throttle, it just feels like it's not pulling.



I'm sure I need to dig into the carbs - and I have the COLOR version of the book to do it now

I was just wondering where I might look specifically for trouble.



Thank you,



Chad

If possible check the balance of the carbs?

Thanks for the reply Shep. Can I ask why you're thinking balance - asking out of curiosity.

If my carbs go out-of-balance(Rare) I almost always get a flat spot around those revs as a warning.It's not the only cause of this symptom though.Bad plugs/Plug cap or tired coils getting warm can also cause it as can dirty carbs.

As I like both my CX to have a full and responsive rev band I'm tuned to the bikes,if you get my drift,so I instinctively know when something is not 100% and it rankles on me until I fix it.

This is one of the problems of running two of them.As soon as one is not as good as the other it's like an itch that has to be scratched

Shep - I get your drift...that's exactly why I'm "rankled." When I was in High-School, I had a pair of Honda XL185 on/off road bikes. Each definitely had their own personality even though they were of similar mileage and same year.



Regarding the CX500C, It's not a place I tend to spend a lot of time with the throttle, but now that I know it's there it's like I can't avoid going there. I'll get into the carbs this Winter with Larry's book and then have to purchase a decent synch tool.



Thanks again for the comments.

I'd like to tell you to save your money on the "decent synch tool". Make your own manometer out of 2 glass bottles as described somewhere in the tech forum. Works fantastic and is every bit as accurate as the $100 tool.
