Had the exact same thing happen the other week - bike wouldn't run except on full choke. reason was blocked carbs from rust scale in the tank. to clean it had to put rocks in the tank and shake it around with fresh fuel and rinse a few times. if you clean the carbs, use a very thin wire down the jets and especially the idle air passages from the intakes. there's some good solvent based carb cleaner spray that dissolves most of the crap that can block it

Don't use wire unless it's very soft, you don't want to scratch the jets

after reading all of this, I can only say this... Im glad I had a 89 CBR250 that had little to no carb issues, and I'm damn happy that I have now got a bike with Fuel Injection...

EFI can block up just the same, the difference being you probably won't be able to fix it yourself.

Youtube search it. Bloody simple and effective method for cleaning injectors.

HA HA! , I wouldnt be able to call myself a Genuinely certified back yard mechanic if I couldn't fix it! ( that or i find more tools and ask uncle google for help )

though admittedly, I still have a bike with a carb, its a bit of a paperweight with out half it assembled at the moment though

Now another carb based query.

After riding in the rain my bike won't start. I stop and turn it off and then have to wind the idle up and pull the choke in and keep trying it for ages before it starts.

I've just gotten into work from riding in the rain and let it idle for a minute or so to try and maybe burn whatever water has gotten in there and nope still had the same problem. Once it finally started I turned it off again and it started first time after.

?????

You sure it is not water getting at the electrics?

[awayatc]

Spark plug lead cracked/poor condition...?

also in regards to getting water in fuel when it rains....
when you ride and use petrol, air gets sucked into tank, so make sure it sucks dry air (i.e no foam ring under filler cap )

[Drew]

If it comes right as soon as it dries out, it's something electrical getting wet. If it takes quite some time to come right after it's dry, it's in the tank/carb.

So, replace the plug cap and you will prolly be sorted.

I'm not sure stop-start-stop and start again would dry out electrics. It turns just doesnt turn over (I'm not sure of the right terms there) just like if I was trying to start it cold.

I don't think I've ever touched the spark plugs or the cables. Are those the same as the timing things where its meant to be 1342 or 1243. If it's that then I already know something is wrong there as its set up 1234 which is wrong no matter what order, but it seems to work that way and I've tried putting it in the correct order (as per the manual and lord google) and it wont start. so 1234 it is for now.

Are spark plugs expensive?
