Had a simliar running problem with my 02 FSE 400. The bike would start and then run intermittently coughing etc. It turned out to be the fuel pump relay located in the airbox area. These are not expensive to replace at 7.00p. Alternatively if you cannot get a relacement immediatley go done the car breakers yard and raid a few engine bays like i did and got a few spares for free. The standard seimens part V23073 is a bit prone to vibration damage. I found a Japanese made DENSO equivalent that was alot more reliable. Cars they were in are BMW 5 series, Toyota Corrolla. Happy hunting (:-)

The only issues I have had with my '02 Fse400 running wise have been with the charging circuit and only because of loose/broken wires. They run terribly if they don't have proper (14.4v) voltage. At the end of the day they are just another motorcycle if your dealer can't fix it find a better mechanic.,,,

Bajaj pulsar 180 dtsi backfiring while starting? why? and missing after starting.

check first if all cylinders spark plugs are firing, seem like you are missing on one cylinder. this will cause as well backfiring.

if this is not the case then:

backfiring can be caused by too rich fuel mix or by wrongly set advance. there is unburnt fuel present in exorst and this cause backfire. these two are most "popular" causes of the backfiring.

hope this will help you solve the problem, do not forget to vote...

Will not start backfires

Prob miles off here but my zx7r did this after being sat 20 months. Turned out it simply had exhaust gaskets totally inoperable. The block where the pipes come out, therefore was in fact sucking air in as the hot fumes were spitting out, mixing up and creating a mini explosion. Check pipes are all sealed nicely tightly. Everything else you did sounds right. What about lifting tank off - airbox off (check that) and look at carbs? clean? Sounds daft this but is it sat with 2 year old petrol in the tank too? It's as if the mixture is going in, plug is igniting but then like its no compression? Mine 'was' simply exhaust gaskets. Think they would do the same if you totally stripped the whole exhaust off and tried starting with a couple of dirty great holes in your bore. Will it not even start with jump leads to a large car battery? Did mine to our landrover and forced it to start - endless charge from running landrover. Take a plug out, connected to your HT lead, turn it over but touching / earthing plug onto part of your metal frame / casing. Should see the actual spark, if not its your coil / ht leads??? Not an expert just had Kwakker long time lol. Love hate relationship.

Bike lost all power while riding. Lights, guages, and everything else. Stayed operational for a little while, then started backfiring very bad, and finally left me on the side of the road. The battery...

it is most lightly the stator or voltage regulator in your charging system not charging your battery while running, thus runs the battery dead. If your battery is completely drained, which usually is the sign when you have no lights and backfires and the battery has no juice left to support the spark plugs, and finally gives up, and thus won't take a jump. This is a common problem. Battery needs to go on a charger and fully charged before you can conduct any electrical output test from the stator or voltage regulator. Just happened to me again this week. Hope this helps.

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!

1983 Honda CBX 550 backfires a lot and has no power

If the fuel is a year old, Replace all of it.Stabilizers are not restorers. Your backfiring may very well be due to the inconsistancy of the fuel. Try it and see if that gets you flying.. good luck

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
