Petrol/Throttle problem. Help needed please

On ,my way to work yesterday my Yamaha Fazer 600 was really struggling. When i first left the garage i could feel the bike not pulling well low down in the gears. After filling the bike up with £10 worth of petrol whicn would normally get me about 100 miles, the bike was in resereve less than 15 miles later. Thoughout the whole journey the throttle just wasn't in the right posiition for the speed i was doing. I also notice during some of the journey that a tiny bit of smoke was coming from the exhaust. When i got to work i could smell petrol but looking over the bike i could not see any leaks.

Anyone know what the problem could be and what costs are going to be involved to repair it

Fueling problem

I had something similar a few years back on my Fazer 1000.  It turned out that the cause was a punctured float that was then allowing too much fuel to flood the carbs.  (In my case due to an incompetant mechanic!)  The smoke you are seeing is probably the result of the oil being contaminated with petrol.

If this is the case the fix is not complicated.  Take the float bowls off your carbs and check your floats.  If you do have a problem with one of them you will need to buy a used set from a breaker to raid for parts.  As I discovered, carb parts are not available - you can only buy the complete unit from Yamaha which are stupidly expensive.

have you had the jet washer out?

Possibly water in the carbs.

Drain your carbs and fit some fresh plugs.

If that doesn't sort it, as marcus said, its whip the carbs off and check your floats.

overflow

I would agree with Marcus,your engine oil/filter will have to be change and your carbs overflow pipes checked as well as fuel pump pressure.

Twat? Nah....

Dan,

Don't feel so bad.  We've all done something silly at some point.  Look on the bright side, at least you don't have a fault that you would otherwise have to spend time/money on fixing.  :smile
