Bang!

I replaced both of these and haven't had a problem since, been running fine now for 2 weeks with out a hiccup.

I hope that this helps

Would it actually cut out long enough for you to have to restart the bike, or was it just for a split second before backfiring?

That sounds cool.. Flash bang

That's what makes me think the reg/rec is OK.. lights, horn, indicators etc all appear to be fine.

Do you think it's possible that it's all down to the alarm.. immobilising for a split second, causing it to backfire when it reignites.
And now just packing up all together?
Surely if this was the case though, I'd have to disarm it with the fob (which I can't do ffs), no?

You have an alarm that won't let you start the bike, and random electrical gremlins.... I would suggest the two are related. I'd start by lobbing the alarm in a skip and righting any damage done to the loom by the alarm fitter.

I've started thinking this myself.
Wouldn't really know where to start (as I'm sure you realised when I was trying to restrict my bike ).. I'm guessing take pannels off, follow the wires from the alarm and then, Just remove them?

Would this definitely "re-mobilise" the bike?

Basically alarm cuts into several circuits and puts itself there as an extra switch.

To do it right you need to be able to solder, and follow wiring diagram. It's a bit of a pain of a job (ask melody about that one before NW3 hehehehe)

Thought it'd be better to dig up this thread than start a new one...

Don't leave it to chance Josh, have a dig around and find the offending connection or wire!

I'm afraid to say that you were correct (not that I doubted that at the time)
Riding back from Soho on Friday the backfiring/revs dropping/ cutting out have started again.

When I had the bike in pieces before I checked all the wires the best I could, but couldn't find the suspect.

Could it be the sidestand switch causing these erratic backfires? If so how would I check this?

Wondered where you got to on the A3.
If you think its the side stand, find the contract and follow the wires around to see any breaks or lose bits.
If your still having troubles give Riverside motorcycles a call and ask over the phone, that could give you a better idea, or i can pop in an ask some time this week if you want ??

silly but sidestand switch? is the sidestand loose and when you hit a dip it moves and loosens off the sidestand switch causing the engine to temp stop as thinking sidestand down, then as comes back up engine fires up and ignites the unburnt fuel-bang-

had a similiar prob years back with a gsx400- new sidestand spring cured it

Will have a look when I get home. I hope it's that simple

Just bypass the switch
