Has it always done this or is this a new problem?

Just throwing out ideas-----> If it's always been like that then maybe the pilot circuit isn't jetted properly. Rich pilot jets start great cold but are tough to start hot. Where is your fuel screw set? Try leaning out the fuel screw and see if the condition improves.

Mate i figured out your problem worms are no good for dirt bikes,see when it gets wormed up it doesn't run properly,when you get rid of the worms it runs again.
I am so sorry,i couldn't help myself,you see i too am bored.

It could be a worm problem because i am everywhere and yet nowhere,more often nowhere.
Man you will work it out,a bit of mucking aboot you will find it,but no more nightcrawlers.

Mine does that as well...having rebuilt the motor I know its not valves etc, got to be the pilot circuit. I'm guessing the air passages have crap in them. Is it just me that finds removing the carb a pain in the rear or does everyone have a nightmare??
Getting the airscrew just right is another hit & miss job...2.5 turns out is about right in my opinion, depending on temp. etc. I adjust mine regular especially when its cold outside. Good old British climate eh??
ps where in the uk r u?
