Solved (I think) !!

Having spent the day avoiding the removal of the carbs, I finally decided to have a look inside the float bowls -- nothinfg to lose, right?

Each of the floats was set at or below the minimum height, allowing too much fuel to accumulate in the carb bowls. These are now set at EXACTLY the maximum height to reduce fuel volume inthe bowls.

The real clincher, though was when I opened the bowl on Carb #2. The main jet was loose inside, and the needle jet was turned and displaced in the emulsion tube.

Thanks to all who offered advice, but especially, chuck(ycheese), and Dink for pointing me towards the bottom of the carbs.

I haven't had the bike for a comparative test run yet -- I used the part tank that was left for the last unsuccessful attempt, and the gauge finally stopped plummeting towards empty, and the bike pulls evenly while accelerating -- way more torque! Now I should keep an eye out for some new coils -- a "fatter" spark might be nioce

Tomorrow afternoon should be a good time to try a test ride over longer distance, as I can join up with a friend to share the trip in case trouble shows.

Thanks once again for the support from each of you.

sv650, I thought your model had fixed jet needles?

Loose jet

Glad you got it figured out David...I thought the loose jet theory seemed logical but...I'm always a little bit surprised when I'm right. :roll: :roll:

How hot are your exhaust pipes getting? If you're passing that much fuel through the combustion chamber I doubt that the pipes would be very hot.

Only in America (the United States of). In countries without the guidance of the EPA, both the idle jet and the jet needle are adjustable on carbs of this vintage.
