She won't keep turning over

Hi - I'm back, looking for more help.  Hope ye guys don't mind.

This is the same bike as Topic: Performance / Speed Limited. ( http://gstwins.com/gsboard/index.php?topic=32720.msg363337#msg363337 )   But a diifferent but maybe related problem.

The quick and dirty version.  I bough my bike second hand, it's a 02 model registered in 04 - there seems to be some ambiguities about this that my dealer (a dodgy bloke) keeps skirting around. Anyhow, when I got it it kept cutting out when I released the throttle, I could put 60miles on it at 9/10RPM and pull up to a junction, release the throttle and it would just die.  I brought into the dealer, they kept it for 3 weeks and eventually told me that it was a valve clearance problem, they 're-shimmed' it (according to them ) and the problem went away.  A new problem arrived : it would no longer go beyond 8/9RPM (See: http://gstwins.com/gsboard/index.php?topic=24790.msg255525#msg255525 )

I'm in college and too busy to learn how to get my hands dirty and too poor to be paying people to fix it - so I just left it as it was.  Last week, I got the air filter replaced with an OEM part, the one we removed was not the correct air-filter for my bike - the mechanic reckoned it was for a 250..... See the link at the top of this post. Now the old problem is back - the bike cuts out every time I release the throttle.



(Some Additional Debug Info ) {

It's always difficult to start now, even after a mild night.  The choke seems to have little or no effect.  I can rev the sh*t out of it  for a couple of mins, but then I let go of the throttle and it just dies.  The thing is if I do this and go away for 10mns, then 8/10 it starts when I go back to it.  But it rarely reaches 1200RPM at idle, the idle screw has little effect on this behaviour. 
}



Any ideas would be appreciated - I have to get my carbs cleaned (as suggested by manofthefield last week) - other than that, new sparks, oil, oil-filter, air-filter and the carbs were recently balanced (albeit before I replaced the air-filter)

Thanking you in advance,

Alan

Hmm... idle issues, changes with air-filter, dodgy registration/previous owner... I'd say check your jet sizes (main, mid, idle); previous owner could've screwed with the jets for his "new" air filter.

I say quit riding it until you get everything fixed.


The valves, the airfilter, the jets, give the bike a complete once over.

Hi,

Do you think  I could be damaging it by driving it the way it is?
