hedgehog Posted February 25, 2011 Share Posted February 25, 2011 I went out to start my bird today to run it up to temp and listen to it hum. Instead of purring nicely, it backfires and will not start. I fires some and then I will get a backfire. I have a 97 bird. Most eveything is stock excep my exhaust. I have never had this problem before, usually it just starts, maybe a little hard sometimes but it would always start. Anybody have any ideas? Thanks in advance.

rockmeupto125 Posted February 25, 2011 Share Posted February 25, 2011 How long has it set? Chances are, fresh plugs will cure your illness. Quote Link to comment Share on other sites More sharing options...
spicholy Posted February 25, 2011 Share Posted February 25, 2011 Did you use a fuel stabilizer in it? Quote Link to comment Share on other sites More sharing options...
The Krypt Keeper Posted February 25, 2011 Share Posted February 25, 2011 holy crap a backfiring bird... man she is toast.. You live close? I will give you a crisp $100 bill for her. plugs, carbs come to mind.. Quote Link to comment Share on other sites More sharing options...
hedgehog Posted February 25, 2011 Author Share Posted February 25, 2011 Its been sitting since I last run it in November. I put Seafoam in with every tank full of gas. I guess I will have to wait until it warms up around here and then try again. I replaced the plugs only 2400 miles ago and the bike only has 16k on it.

cbrxxquad Posted February 25, 2011 Share Posted February 25, 2011 What is the very last thing you did to it... Quote Link to comment Share on other sites More sharing options...
hedgehog Posted February 26, 2011 Author Share Posted February 26, 2011 I drove it around awhile, filled it up, put some seafoam in, ran it a little longer to make sure that the seafoam was in carbs also. Then I let it cool, pushed it into the garage, attached a battery maintainer, and covered the bike. That is it. Quote Link to comment Share on other sites More sharing options...
rockmeupto125 Posted February 26, 2011 Share Posted February 26, 2011 Its not uncommon for a carbed bird to foul the plugs in cold weather after sitting for some time. Its certainly happened many times to me. With the usual 3-4 birds in the garage at any one time in various stages of repair, they don't get started and run on the most regular basis. If you can spin them over strong and fast, they generally fire well, but using most of your charge on the starter just seems to let the plugs get fluffy. Another thing is the shite gas we're getting now. I used to strongly advocate a full tank of gas and Stabil for the winter months...now I'm considering running the tanks dry instead. With the alcohol fixation our asshole government has, gas does not seem to remain stable for as long as it used to before they started doing things to make it better.

rhubarbray Posted March 3, 2011 Share Posted March 3, 2011 Seafoam is a cleaner, not a stabilizer. I`m also leaning towards plugged carbs, perhaps next winter use Sta-Bil to stabilize the fuel. And a friend of mine has used the parts store version of the stabilizer and then had problems the following year. In this case I`d recommend only the Sta-Bil name brand.

Jaygermeister Posted March 3, 2011 Share Posted March 3, 2011 Do you guys still have the original vacuum hoses?? One of mine dry rotted and cracked and was giving me that sort of problem or your main jets could be gummed up. Quote Link to comment Share on other sites More sharing options...
Biometrix Posted March 3, 2011 Share Posted March 3, 2011 I would also check to make sure no critters have built a nest in your aircleaner or clogged your pipes with their winter food supplies (dog food, bird seed, nuts, etc.) Quote Link to comment Share on other sites More sharing options...
