Weird cyclical stalling.

[stratblue]

Hi All.

Living in the heart of the floodlands as I do, I've ridden the bike through a load of water lately and had to put it away wet a couple of times, something I usually try to avoid. When I started it the other day, the bike kept almost stalling repeatedly, imagine saying the word 'Rum' three times a second and it was accompanied by that strange side to side torque reaction that you feel if you rev a GS in neutral. I took it out for a spin and it cleared up and felt fine to ride, but it was back again today. I'm guessing I need to squirt a bit of WD40 on some technical part of the machine.......

Thanks

Sounds like ignition... the exaggerated side to side torque would suggest (to me anyway) that one cylinder is nor firing well. So when it warms up it's ok because it's all dried out or the duff plug has gotten hot enough.

That's where I'd be starting - the plugs. But others with more knowledge will be along.

Sorry about the flooding. Looks horrendous

did it suck in some water.... you can often get a damp air filter element on vehicles in flood conditions and it'll run like a dog

many seem obliviously of the fun of hydraulic lock - it equals a breakdown and the need for a new engine.... taking a vehicle in to flood water is very risky for your wallet

alternately soggy fuel pump relay, or other soggy electrics

Check your alternator isn’t starting to seize. It can make the engine stall, also sometimes you can get a very short squeal as the belt slips before the alternator gets forced to rotate.
