Moving my saga here, so everything is in one place.
For those that have been watching, and those that have not, I have a barn find 64 CB77 that I have been restoring since December. Things have been challenging to say the least.
She looks good.
The bike starts and runs great. I have clean carbs, new battery, stock jets, needle positions, airboxes - the works.
Been through too many problem to count, the latest being an entire timing saga.
I now have the timing right, but here is the problem, and its persistent.
No matter what I do, when the bike gets good and hot (like 40 mins plus of riding), it starts moving around at idle - up to 2500, down to 600, back to the 1200 initial setting, then 1800 for a while, then it goes way down and stalls.
I ride along thinking I have fixed the problem, and as soon as I pass the 30 to 40 min mark, everything goes crazy.
When this starts, I open the fuel cap and make sure my lines look good. It's not delivery. Tank is clean, petcock is clean, lines are clean. If you pull the bowls when it starts, they are full.
My next step will be to swap the carbs with two others I have. Ordered new kits for them so there will be no common parts with the current carbs.
The obvious answer is an air leak.
But if its an airleak, wouldnt it seal up when the bike warms up?
In any event, thanks to everyone that has helped so far.
But the problem continues.....
