Bonneville America Forums Forums Technical Forums Exhaust Popping and more color on pipes

This is my fifth season with this bike and this has not happened before. When I started her up this spring there was some back firing and more color in the pipes after she got warmed up and one side being deeper than the other. Also she was popping when idling. Now I have made my 2 and a quarter adjustments to the air mixture screws and now she idles well but still colors and back fires but not as bad. Now I still need to change plugs and clean out my air filter. Any one is welcome to put in their 2 cents in.

Sounds like a dirty carb(s) IMO to me, drain or drop your bowls and have looky. You might be able to get away with pouring some carb cleaner in the tank or you might have to go the hold root of emptying the gas from the tank and dissembling the carbs.Did you use "stabilizer" for your winter storage?

I was thinking about dirty carbs as well. I did not use any stabilizer in the fall. I was running the bike occasionally but when we got dumped by snow I was too busy shoveling snow and health problems compounding the situation the bike sat for months. I thought I mostly drained the tank but obviously not enough. I am going to try so carb cleaner in the tank next then take out the carbs and muck out if that’s what I have to do.

Check out the squirrel condoms for leaks.

Mine did exactly the same thing. I found a split in one of the condoms.

I LOVE the "popping" on decel! I'd be really pizzed if it went away. If new condoms made it go away, I'd probably poke holes in the new ones.

Then we'll have more squirrels running around!!
