My 1100 refuses to start. I am getting fuel and spark, but it won't fire. It will start after sitting for a short time but will die within a few seconds.

Any ideas??

Have you tried draining the carb bowls? It could be a sticky needle and seat, sometimes get stuck during storage. I would drain the bowls and then try and start it again, then re drain the bowls this will let you know fuel is making it through the carb. Just my two cents worth.

I'm having the same problem, my plugs were dry so i drained the bowls and they did'nt fill back up. so i pulled the fuel line off the petcock and i could see gunk in it. i have the carbs off now and giving a thorough cleaning, what i think might have happened is in the fall when i put stabil in it i did'nt run it through enough.

I drained one carb, but I cant get the other screw loose. It is getting fuel. It will backfire when cranking.

Looks like I will need to pull the carbs this weekend. Maybe it is just getting flooded. I don't know what else to do. It ran perfectly a few days ago.

I did have the tank off Sunday. Last spring I left the breather hose disconnected from the plenum. I forgot that I forgot to connect the breather and let it go all summer. I remembered when i seen oil on the engine. I pulled the tank and reconnected it and put it together. I always start the bike to make sure it runs. I don't recall starting it up Sunday, but I don't recall not starting it either.

I can't image I did something wrong putting it together.

I can't imagine having a cam timing issue either. I think it is getting flooded.

I pulled the carbs off yesterday and cleaned everything. Put it back together and she fired right up. It was flooding. I did check compression and each cylinder and I got over 120 PSI, so I know the engine is good.

One issue now. I got leaking bowls. The bowl rings were oversized when I pulled it apart. I tried boiling them. They did go back into shape, but they need replaced. looks like I get to do it all over again.

If only Yamaha would have made the 1100's injected, I would be a happy camper!

Thanks for all your help. I greatly appreciate it!

If they did, I'd have never bought one. Carbs are a lot less expensive to tune, plus...leaving fuel in the system like you did could have left you with a huge repair bill..... I'll take carbs any day, if only for that reason.
