I ran through a puddle on the bike today and it seems that i've fouled my plugs, the bike cut out shortly after the puddle/river and then refused to start pretty much till the hot engine finished evaporating the water around it.
I highly doubt i've done anything serious but thought i'd ask here if its just some water on the plugs or ht leads that might be crapping up my sparks?

I know less likely but ive done it before, not possible youve forced water into one of the carbs?, did this on a supermotoard 50cc, rode through a puddle it started bogging roughly 10 seconds later then dead Laughing

Ah never thought of that, i'll drain my carbs tomorrow, should fix the problem if it still persists.

Many carb breather pipes exit downwards and will suck up water when going though even a modest puddle nowadays.On my KTM 450 enduro all of the pipes breath into the airbox where there is less likelihood of the carb trying to breath when in the deepest of puddles,especially on the Strata Florida in mid-Wales.

My XR400 used to have this problem. I used to think it was water getting in around the HT lead/spark plug area causing a misfire but it was related to the carb breathers not an electrical problem.

That was one of the first things that I did to my XR400 was to reroute the carb breathers into the air box.I have since done this on a friend's XR250R.
I also had a loose fitting spark plug cap on the XR which I replaced with a bright red silicone one from NGK.Far more effective in deep puddles.

This years Cambrian was run along the Strata Florida track.Unfortunately a friend had a big problem with her Husky 250 ingesting rather a lot of water on one particularly deep river crossing and had to be towed back to the van.It spoilt her whole weekend as she did not receive her finishers award.

One spark plug was loose and the others where fouled up from too much choke i guess, all fixed just need to balance my carbs

Spoke to soon, the bike keeps randomly dropping revs then cutting out, the air filter is clean, the plugs were fouled but nothing major enough for it to cut out as it was fine previously.
one of the plugs wasnt in the engine propperly but no water is in the oil or got past the ht stick.
Starting to think its an electrical fault but i'm not sure where to look, new plugs will set me back about £20 and is probably not needed.

The bike was running fine if not a bit fluffy from lack of one plug until i went through the flooded bridge, I've drained the carbs and checked that nothing is loose induction end. the sponges in the air box that are supposed to catch water were damp but nothing major again.

I'm stumped. Sad
