water in the carb ?

[nick606]

i took my bike to a garage today after it kept cutting out when i stoped (going from high rpm to low rpm). and a noticable power loss he took it off me for about an hour and did his thing for £18 (he said there was water in the carb causing it) when i got back on the bike i noticed it sounded a tad different and the idle was now almost double what it was (was 800rpm now 1500ish rpm) there is still less power than there was it tops out about 50ish. when i use to be able to get it off the clock quite easy (clock stops at 50).

tbh i though it was the fuel/air filters needing a clean. i have also found out that my bike was running on res all the time and is now in the on position. but when i turned it back on res it sounded like more it did before i gave it to him........
how does water get in the carb and does this sound right because it seem he has just ajusted idle screw to me and turned the fuel tap to on (keep reading/hearing storys of dodge mechanics) . any ideas.
im sure its just me being paranoid he seemed like a nice fellow

he also disconnected my neons (came with the bike)

This is why I like to work on my own vehicles where I can. Unless you watch the mechanic you can never be sure what they've done to your bike/car,

Sounds like your on a moped or scooter, do you have a powerfilter on there? or is it the stock airbox? powerfilters suck up water easily and then it goes straight through the carb and into the cylinder causing misfires etc on a 8 mile trip my bike would cut out about 5miles in EVERYTIME in the wet with a powerfilter.

Things should be ok when its left to dry though.

Power loss and cutting out could be alot of things. Some people say the engine sounds different when the piston rings are nackered.

If he was going to rip you off I think it would be for more than £18. I'm surprised that anyone has such a low minimum-charge nowadays.

Water can get in the tank from the fuel pump or from filling up from a can etc that had a bit of water in the bottom.

800rpm sounds a bit low for tickover on a small-capacity bike, have you checked what it should be?

its a 03 rs50 as john said it ticked over nicely if i didnt go from high rpm to low rpm and if i kept the rpm low before stoping (under 4) the bike would not cut out (this happened when the bike was at optimal operating temperature as well) (did take a long time to warm up) the manuel says the idling speed should be 1100 + or - 100

and the mechanical side of the bike is completely stock as far as i know

Its the same year as mine used to be.

When was it last seviced??

[nick606]

just before i bought it 1-2 months ago... it wasnt used for about 2ish months before i got it though

oh sorry i mean i was losing power about 5 days before i took it to the garage its been cutting about like that since i got it. so i though it was a blockage in my air filter because on top of these my exhaust fums smells a lot like petrol (so i have been told) dont know if they do now though

Maybe be worth getting some carb cleaner in there. Very cheap to buy and very simple to use. Instructions on the can just a matter of taking air box off and spraying into carb. From my person experience it does the job. Have a look at your spark plus like john2 said. JUst out of interest what 2stroke oil are you using?
