Hello all,
When riding, at first it has a normal idle and runs well. Once warmed up, the idle doesn't properly drop down when throttle is backed off. Obviously it is a problem when shifting to have the neutral rpm around 3-3500. Not only that, coasting to a stop light with such an idle results in fighting the bike's speed with the brakes. Have to do all the down shifting at a stop with clutch lever pulled in.
Points and timing are properly set. Throttle slides are synchronized and it will idle around 1200 rpm when not fully hot. Yes, I have to keep the throttle slightly increased when cold to keep from stalling, but it only lasts a little while. The air bleed circuit is properly cleaned with a wire and I removed the screw and shot brake cleaner into the screw hole to force out any debris. I installed the screw and set it to 1 1/8. Seems good.
It doesn't appear to be a gasket leak at carb or the intake manifold. I verified by spraying starting fluid around carb gaskets and there's no reaction.
I'm thinking the only thing left is one or both slides are hanging up when hot. I loosened one nut on each carb without positive result. Loosened it only one flat. I thought the carbs might be over tightened but they weren't. I put the nut back into place using the Goldilocks method.
Anyone care to give opinions re slides hanging up? I did clean the carbs when I received the bike, but didn't pay attention to the slides moving sweetly and only paid attention to the cleaning of the units.
Thanks very much. Steve
