Help!

[Sailor]

Bike just crapped out on me. The two left cylinders keep cutting in and out. I am supposed to lead the toy run on Saturday. No way to get it off the island to a shop. I have cleaned the air filters and I have a socket that fits the carbs but I don't have an extension that will fit the socket. I have poured in a can of Seafoam and am hoping for the best. Any other suggestions?

Coils? Both at once would be odd. Fuel filter maybe?

Try draining the float bowls (loosing the drain plugs on the carbs and letting them empty) than refill by turning the key on and off until the bowls refill.. May have picked up some water in your fuel...

It idles ok but then the revs change up and down. If I rev it up it backfires and the two left cylinders cut in and out. It seems to be associated with the revs.

Has the bike been sitting long? If so, was it stored on the side stand? My left side carbs were all but plugged up when I got my bike. My left side plugs were as black as black can be.

 

Pull the tank and spray the carbs out.

The left carbs share a carb bowl vent hose.....that runs forward and down in front of left air box in lowers.

 

Ensure the hose and carb vent nozzles are clear.

Seafoam, Seafoam, Seafoam, and then, more Seafoam:fingers-crossed-emo

Pulled the air filters and cleaned them. Running the bike every day. Drained fuel out of the tank..no sign of water?????? Letting the sea foam sit in there overnight and hoping it works.

Listen to Neil 86, he knows...

I'd drain all the gas including carbs and throw the old in in a car. Can of seafoam 100% and give a soak overnight. Drain the seafoam, add fresh gas and refresh the plugs. Too many additives in the gas can cause issues also. With the gas refreshed you can test the fuel pump also. See if it runs better

any luck yet Kerry?

[Sailor]

Drained the carbs, checked fuel for water, put in a can of seafoam, sprayed the carbs with cleaner. Have got it from two cylinders to three and sometimes four. I noticed lots of fuel seeming to come from the left two carbs. Going to let it sit tonight then try again in the morning. Running out of time.

[Sailor]

I have noticed that it runs on all four if the throttle is just right. It cuts out soon as I try to get it up a hill.

I am hoping Santa makes his rounds today

do as Neil86 said and then drive it like you stole it.

Worked on it again and all I could get was three cylinders and sometimes four if the revs were just right. Gave up and led the run in my 47 chev pickup rat rod. It worked out well. One of the original organizers has cancer so she could not ride but she got to make one last run in the pickup.
