Do 2 strokes have solenoid valves for the fuel line?

[Major_Grooves]

The longer I leave my bike without riding it, the more difficult it is to start and the more smoke belches out of it. Usually when I ride it everyday it starts first time with only a little smoke, but yesterday I rode it after a 3week break and it took ages to start and belched out loads of smoke.

So I was wondering is there a solenoid valve to close off the fuel to the engine? If there is maybe mine doesn't close properly when I turn off the engine so fuel is flooding the engine when it is turned off and this gets worse the longer it is left.

possibably the fact the battery is slowly discharging and as it does it gets harder and harder to maintain/produce a nice strong spark to run the engin with!?

thus the longer its left the harder it is to start as the flatter the battery is?

just a suggestion!? could be total carp

Maybe, but that wouldn't explain why the smoke is worse the longer you leave it. I was thinking the longer you leave it the more fuel leaks onto the cylinder heads so the more fuel is burnt up there when it starts.

Bikes always smoke more the longer you leave them. Both my NSR and my RF do.

as demionic said.... same with most engines I would expect ... it probably just needs a bit of time to burn of all the crap that has settled.

Can I do burnouts... hmm...

Well I've never actually tried one, but I would of thought it was pretty simple.... first gear, weight over front of bike, front brake on, rev the bollocks off it...

What bike you on scoob?
Burnouts are easy except on 125's. I've tried everything on the NSR:)
I now have a nice square patch down the middle of my tyre on the RF though

I never had a problem on my NSR... used to use them to turn round in Sainsburys staff carpark when I worked at Starfucks

Just go on the grass!!

I ain't on a bike at the mo. I have a blown up NSR125 2001 model in my garage which I siezed doing 95mph down an A road... getting it fixed when I eventually get paid (bout a week away) then selling the fucker coz it's depressing opening the garage to find the frame on one side of the garage and the engine on the other side...

Oh well it's all acadmic now anyway. My bike died just as I pulled into work this morning. I don't have a clue what is wrong, and I had a few guys from work have a look and they don't know but thought it could be electrics. I guess it will cost an arm and a leg to get it picked up, taken away and fixed.

Arrgghhhh.... I knew that damn bike would be the better of me!!
