Popping and backfires when decellerating


The primary cause for backfiring on deceleration is an air leak - if the baffles have been removed or modified or if the gaskets in the exhaust tract are not sealing properly, fresh air can be introduced into the exhaust stream causing a pop or backfire. Check your exhaust system - especially if you have recently had an oil change, since the pipe has to be removed to change the oil filter on this model.

Have a 2004 yamaha classic changed to K& D pipes ran fine then 2 years ago after an oil change it started backfiring on deceleration and has gotten worse...have spent over 7 hundred dollars and no one...


Well - the front pipe has to be removed to change the oil filter on this bike, so it's very likely that when reinstalled the mechanic did not get it back in place correctly. Couple that with the likelyhood that he re-used the old exhaust gasket and this is your most likely cause for the backfire - a simple exhaust leak. Other typical causes for exhaust backfires are insufficient valve clearance, burnt valves or incorrectly adjusted carbs. In my experience the most common cause for exhaust backfire is a leak in the exhaust circuit which can draw in fresh air during decelleration.

Engine backfire on decelleration Timing Checked


if is doing it thru the carb then the fuel mixture is too lean, if is in the exhaust (also called after-fire) the fuel mixture too rich.

Vstar 1100 idling rough and backfiring letting off the throttle


It sounds to me that your carbs might be a little gunked up - you mentioned the gas may have been old, so it's possible that the smaller (idle) jets are slightly plugged up. Fresh fuel might do the trick and/or you could try using a fuel system cleaner and water remover. This problem might 'solve itself' with a little time.

As far as the backfire - this might be either from the carb issue or it could be related to that rattle you mentioned - you could have a loose connection at or near the head - this can **** air and cause a backfire.

I hope this helped!

Backfiring when idling back down thru the gears


that seems to be what they do, i too have a 650a and have jardines on with baffles, it still pops and cackles when you roll off the gas. are you running no baffels? when i took mine out i noticed a drop in power as i had removed the requierd back pressure for optimum performance. you can get small baffles to slip into straight pipes from jc whitney for about $5 each.
anyway back to the backfire. my local bike shop shrugged their sholders when i asked them about mine saying it's what they do. you will get used to it and you will find a way to kinda not make it do it so much. i actually have grown to like it now, except when there are cops about.

happy safe riding

Over fueling and backfireing through airbox


Your bike has a compression release if I recall correctly. Chances are that the compression release cable got stretched or kinked when the bike went down on the black ice. This means that the valves are not fully seated and THAT is probably why you now have the backfiring. As far as the carb floats go, chances are they are perfectly okay. If a float were stuck open then fuel would be leaking from the overfill tube. If the floats were stuck closed then the bike would not be running at all.
..
Check the compression cable and linkages for problems. Be certain the compression lever functions freely and properly. Also, check the carb cables. Be sure the carbs are balanced and in sync. Doing these things should fix the problem.
