GL1200 backfired won't start

Post by dano955 » Wed Mar 06, 2013 2:56 pm

First of all I want to thank everyone for their advice and help. if you look at my past post i having one problem after another.
starter would not engage (turns out to be a weak battery)
plugs were not firing (i checked everything and discoverd engine shut off switch need cleaning)
now it won't start, backfired real loud (like someone shooting weapon) now i am thinking that because it hasn't been run in about 6 months and the way it backfired i need to clean the carbs
i was hoping someone can tell the best way to clean the carbs without takng them off--where is it that you can drain the carbs. nice weather is on the way here in Ga and i am ready to ride--was thinking about buying a new one but i've got a attached to much this one (my wife says my baby)

Each carb has a drain plug on the bottom.I use a very long screwdriver to reach them and a rag to catch the is done by disassembly or some magic gas additive ( sea foam )
If its been running poorly,the exhaust may have a bunch of gas on it that ignited ( stuck needle valve/flooded cylinder).

Be sure and check the spark wire placement. Easy to get them mixed up. If the bike is still setting put in some Star Tron fuel stabilizer. In Walmart in the marine section. Then when you get some fresh gas and it's running try the sea foam. But if the bike sat a long time and not drained of gas. A carb cleaning may be the only way.
Enjoy the ride. They are all good, just some better than others.
