Default Curvy starting and Idling Problems

I've got a '99 curvy with around 30k on the clock. Lately I've had two problems:

1. My bike usually starts first time no problem, if however it stops soon after starting, usually sidestand sticking on the way up and I put it in gear, it struggles to start again. It usually does eventually but keeps trying for ages before it fires.

2. Once the bike is warmed up, if I'm sitting idling say in traffic, my oil pressure light keeps flashing on/off. It never comes on constant and will not do it if I rev the bike a bit more. It currently idles at around 1400rpm which I think is correct.

Just wondering if anyone knows what could be causing either problem and any solutions. With regards to problem 2, is this likely due to engine wear and expected or is it a big problem. Any advice would be much appreciated.

As above - 1400rpm. I don;t know if raising it would 'hide' the problem but I think 1400rpm is the recommended anyway.

Does it hold a steady idle when the throttle is closed or does it 'hunt' around (travels from 1k up to 3k etc)

It remains pretty steady once warmed up. WHen cold it can creep about a little but is always stable when warmed up.

well thats ok i hav an 01 curvy n it was huntin etc and i needed to get the carbs balanced and all. check and see if your choke is sticky, once the bike warms up the choke will flood the engine instead and cause it to bog down and die, u can check the choke plungers etc in the carbs but i wud recommend play about with the actual choke control on the bars and see what happens, try pullin it all the way on and slammin it off etc
worked for me when mine went a bit sticky!!! this isnt technical help jus sum things to try without dismantlin the bike right now haha

Cheers, I had the carbs balanced around 5k ago and think they're still OK. I'll try that with the choke but I don't think it's sticking. I usually use it on a bit when I start it when it's cold and let it warm up then turn the choke off and the revs fall to normal idle so don't think it's sticking.

As for the oil pressure light, the most common thing is for the pressure switch to be faulty. It is possible of course that you actually have no pressure....................

The oil level is correct isn't it?

I'd go with the others' suggestions re the chokes. The only reliable way to check is to take the plungers out and see what state the cables etc are in, no white cruddy corrosion. You're unlikely to feel anything at the lever end, it's usually a case of the plungers not closing fully which you don't feel (spring return).

Cheers, the oil level is correct, I topped it up the other day to slightly below the max mark. Looks like I'll need to have a look at the choke, hopefully I can this weekend.
