problems starting/running

[Andyk]

when i try to start my bike i need to have the choke fully on and turn the throttle several times untill it catches. after this i then have to ride for around 5-10mins with the choke on about half to warm the bike up otherwise it stalls when coming to a stop

what could be causing this?

Cheers

just to make you feel a bit worse-er

i started my ye olde CG this morning, at the point i normally turn the choke off i reach down i realized i had left the choke off, but it had still started anyways

Sounds like the OP's bike is running lean or has a vacuum leak. Check the condition of the spark plug. It should be a nice tan colour.

As for Mudcow's bike, the CG may be running a little rich but with the slightly warmer weather, then choke isn't always needed

[P.]

Put choke on, press starter. Ignore the the throttle.

Tickle the throttle, no need to open it all the way, just 1/8th, if that.

Start it on choke, ride gently for a mile and knock the choke off. Your idle when warm depending on bike should be a bit above 1000rpm. Most bikes I've ridden are between 1200rpm and 14rpm when warm.
