just picked up 06 450 smr and the bike pops on decel sometimes. All the hoses from the carb tie together then one hose goes up along the frame under gas tank and stops. some of my hoses had gas in them and no way to vent. These hose connections make no sense to me. Can i just have all the hoses hang below the carb?
I believe you can have the hoses hang below, esp with an smr. Have you checked out the seal around your header pipe and muffler, if they are loose this will cause popping. That said a little popping is normal. Too much popping can mean the fuel mixture is out as well-too rich I think? Gee its good to get a carby question in this section. Its been full of the efi guys issues lately.
Mine are usually 2 up, 2 down, like on other bikes. For my 2006 TE250 I have a vent filter installed, but the concept is the same. Fuel in a vent line is a really quick way of making the engine not run. I realize you may not see this, you only have 1 post, but you might.
