backfiring?

Post by shaun1978 »

just thought i'd give my storm and mille a warm through this afternoon, but one thing that still bugs the hell out of me , everytime i start the storm it ALWAYS backfires and then immediately strikes up....., I'm wondering if its got a dynojet kit fitted, its always done it just never gave it much thought.
It also "sneezes" a fair bit when I'm running slowly through a built up area......

any ideas?

Enjoy the noise :?:

mines never pops or bangs at all ,...infact it's only done it once, it was a hell of a bang in a buit up area, it was totally out of character for it, sounded like a gun going off, i was so taken aback i stopped the bike and checked it over, i thought i'd ran over a bottle or something which had exploded:!:

It's seems to be the bit of "character " mines is missing ,maybe not a bad thing though :!:

Standard cans and filter fitted ,even after drilling holes and eventually removing the end baffle completely, it still never popped or banged :!:

Definately an exhaust/fuelling/filter issue IMO. I had a combination of standard cans and filter and it used to cough and bang occasionally then moved on to Scorpions with standard filter and it was much smoother but still farted through the carbs on occasion. Changed to custom made shortened cans with BMC race filter and trademark farts were all but eradicated. Might be worth asking Silver Zipper what my bike is like now with standard cans and BMC filter (if still fitted).

If you haven't done it (or had it done) recently, balancing the carbs may help :!:

Loosen the clamps holding the cans on. That should draw in enough air when you shut the throttle and get it popping on the overrun. It's childish but V twins sound good like that :)

It's running remus cans and a K&N filter which was on it when i got it ...... this is why i'm wondering has it got a dynojet kit fitted as it seems to really overfuel.
Will get the carbs balanced ASAP tho....

think this may just end up being a track bike lol

Hmmmn, some (RedStormV :D ) will disagree but the K and N seems to need perfect setting up to run super smooth as opposed to others that need less attention to jetting etc. Also if you try the standard air filter as it has cured fuelling issues in the past.
