Cold start problem

Post by lucagw »



Hi, my bike has been sitting in the garage for one month, now. We are in winter so temperature in the garage can go quite low. Yesterday I tried to fire engine up but, curiously, it would not fire up using the choke. Without choke, instead, it would fire up staying at idle for 2 seconds before stopping.
Shouldn't this thing work in the opposite way??

Might need more investigation... wet plugs, flooding carbs, main jet sliders stuck open, etc.
But here's a "guess".... Engine is flooded due to leaking carbs or something. Too rich to start with choke on. Then with choke open, excess flooded gas clears out and it fires up. But after burning off the excess gas, it gets back to "normal" for a cold engine and now needs some choke to keep going.
My guess is a stuck float. Might free up with gentle tap on the bowl.

My '83 was notorious for this. I regularly ride in COLD weather. It never started with the choke on. I always went no choke- 2 to 3 twists of the throttle- hit start. As soon as it started I hit the choke full on. This works down to 15 degrees, thats as cold as I have ridden to work.... The bike had a little over 100,000 miles on it before I upgraded to an '85.
