A 8th less then 1 full turn. And yes you could be not getting the bike hot enough before taking off but that usually results in a cold foul.
Go to this setting and warm good to the touch and crisp throttlr respounce and run the bike hot as you can on hills straits ect. NEW BR8 plug.
Even if it don;t foul pull it and see how its running. Get back to us.....

o and also, when starting the bike cold. turn choke on and start with no throttle. blip throttle, not hard blips, just a quick small twist of throttle, like 1/8 turn on the thottle is the farthest i go. do this until you get a clean response then turn choke off. and let bike warm up for at least a min, 2 mins is probably better. my manual says to warm bike up by slightly twisting throttle. and as time goes by keep twisting it more and more.

when starting bike after its warm, keep choke off. and kick it with throttle slightly turned.

dont let the bike idle for more the 20 seconds without giving a blip on the throttle. you can give a nice bigger twist now that the bike is warm. you do this so that it doesnt load up with carbon.

nice 1 for the info lads ill go and set my air screw now and do the warm up properly like you said and 1 thing i for got to mention is i don't let my bike tick over i have got it set so when you are in neutral the bike ticks once then stalls is this right or should it tick over for 5 seconds before it stalls or should it tick over all the time i could do with knowing this please thanks  

by tick do you mean idle. my bike is set to not idle at all. you get better throttle responce. but the most that i would set mine to idle at is 30 seconds.

yes sorry i meant idle  

For your application after getting the bike warm and air screw adjust, Turn your idle screw in till it will idle at its lowest RPM.
The bike MUST be ready to go warm wise when doing this! A good 20-30 tick over will help as well.
Your on the right track. As Elk said some go with none, And thats for track or real open trails and on the gas all the time. But your going to want alittle tick over. Adjust as i said.

i don't no if this helps but i have just took my air filter of and inside the air filter black box there is a small amount of unburnt oil liquid just sitting in there  

hi all been out on my bike tonight and the bike was running fine a bit better than usual then the inevitably happend the bike started to bog down then the plug failed on me it lasted 2 hours then i put another plug in it and after a bit it did the same fouled the plug so i have checked the plugs that fouled today and its carbon fouling on the filament and oily liquid round the threads and I'm just wanting your lots opinion I'm using Bel-ray H1R and mixing 40:1 is it worth going to 50:1 and please can i have more answers to the reason why the plugs keep fouling on me                

the bike is not running at a temperature high enough to burn the oil. try adjusting the air screw to max rpm or best throttle responce. if it still keeps fouling plugs then your top end may be worn.

the plugs was fouling be4 i did the top end previously and that was only 6ish hours ago so the top end is fairly new and how many turns shall i do the air screw to get it up to temperature  

no one can give you answer to that. that is something that you have to do. put the bike in 3rd gear and twist the throttle about 1/8 to 1/16. barely turned at all. if it bogs then turn the air screw 1/4 turn out. and do the same thing but this time snap the throttle all the way open. it should not bog at all. keep doing this. if it runs fine when throttle barely turned but then cuts out when you snap it open then turn the air screw in a little bit. now your air screw should be set. if you go past 2 2/4 turns out from slightly seated then you need a smaller pilot jet.
