Problems starting

**Sheep Dags** · 15th January 2004, 16:06

Hi,

I was reading another thread about not being able to start a bike etc etc but my problem's a wee bit different. Pretty much every time I go to start my bike, regardless if it's been sitting around for weeks or overnight, it just won't start. It's a 2 stroke NSR and when cold, I can be kicking for minutes before anything will happen. So now I just turn the key and push it down the road... Then it starts fine. I can start it warm fine, but anything over 2 hours of not using it and it's a bastard. I've just recently changed the plugs and that didn't make a lick of difference, which fuckin pissed me off cause they cost me a fortune. Anyone got any ideas? Maybe something wrong with the choke?
Thanks heaps,
Mike

I find with mine if you gently just push the kickstarter down once right to the bottom, then give it a good kick after that it usually starts first time... dunno if that'll help you tho.

My KR 250 sp does exactly the same thing. Now carry a can of CRC engine start to the track with me.
But the RGV I had was real easy to start.
The RG 150 I had was a bit temperamental at times when cold. After a number of kicks, it would fire up,, just,,and die if you twisted the throttle.
Then sometimes it would fire first kick and be fine.

Two strokes! What can you do?!

What's the battery like? Post a voltage.And the rest of the connections?
General condition of the bike/what's it run like warmed up?

ummmm,

Na it's all good once warmed up, it goes sweet.
The only thing is when it's cold it won't start. When warm it will start sweet.

Should the battery even make a difference? Cause it is a kickstart so the battery shouldn't make a difference should it? Specially seeing as it starts first kick when warm anyway.

Should I take it into a bike mechanic to see what's going on? Maybe they can help me... how much you reckon that's gonna cost?

Cause it's a sweet bike but this is the only problem with it, and I'm about to put it on the market to sell but don't want to sell it with any problems.

thanks,
Mike

Yes, the battery does affect the initial start. It should start charging after that. If you have a multimeter, you can test that.
If you dont, pm me, and I'll test it for you

If you want to sell, I may know somebody........
Checked plugs? not old/fouled? How well does it spark? How is the compression?

turn the gas off when you stop - on 2 strokes you should do so everytime you stop, if you have a faulty tap the crankcase gets gas in it and it can make it hard to start,
also you havent mentioned if you use the choke for cold starts

Good advice turn off the fuel tap between runs. and before you try to start it next time whip out a plug first and see if its dry. sounds like a fouled plug to me or a gap issue I have a victa mower 2 stroke and if you leave the fule tap on forget it the principle has to be the same.

Thanks guys,

Yea na I leave the fuel tap on all the time but it always starts when warm (eg anywhere up to an hour after riding last), so don't really think it could be that. I have recently changed the plugs and when i changed them the exact same thing still happened so don't think it is the plugs either. I've also got a Victa 2 Stroke mower casue i'm a lawnmowing contractor and I find that if I leave the fuel on I have trouble starting it... But I've tried that before too, turning the tap off after a ride and yet still have the same trouble. You reckon it would be a good idea to drain the fuel out of the line before turning it off?

Also, would it make any difference that I stop the bike with the key, not with the engine stop button? Cause I do that too :P

If anyone's interested in buying it, let me know... This is the only problem I have with it, otherwise she runs pretty sweet.

If its not starting from cold could possibly be the engine getting tired? The compression is probably too weak.

I think you could be right there andrew-Also try it without using the choke-
Oh, and don't turn the throttle until after it fires.

my grandfather would always make me turn the tap off on the 2 strokes and let it idle to a stop, especially if parking up for the night. It's also nice for the engine to settle to an idle & the temperature to settle after a ride & plus you get to listen to it and can 'tune in' & pick up on any problems etc.
