clutch slipping on start up and cant run without choke

Aren't the clutch pads made from ASBESTOS ?

in the china kits.

Sanding asbestos is a no no.

even i know that one.
sounds like he had a vapour leak,
the colour/wetness/spark of the plug,
this determines what the engine is doing.

But, I do make claims that I usually get flamed for.
 
It's been quite awhile since I've touched my bike but I think I solved that problem by sanding the friction material and the clutch plate to remove the glazing. If you do find a stronger cluctch spring I don't think you will need to crack the case to change it but I could be wrong.

Hope this helps

Are you certain you don't have the clutch cable too short? That would hold the clutch partly disengaged causing it to slip on start up but maybe have enough grip to go once you got moving. It's a balance act between the flowe nut tightness and the clutch cable length. Get it too short and you have the problem you have now, get it too long and you can't fully disengage. Good Luck!
 
As far as the running with the choke on or partially on, You are getting to much air to fuel mixture when the choke is off. lower the needle clip one notch. That will give you more fuel to air mixture (making it richer). As far as the clutch goes make sure the clutch plate is moving evenly and not binding on one of the three pins.

Not to take over the thread,

Maybe before, I had it down one clip and bike wouldn't start easy.
I Can't remember.

Just spotted your post.
Is it possibly sucking air at the carb/inlet or inlet/cylinder joint?
 
Will Start: Try spraying the manifold to cylinder area and the carb to manifold area (W-D 40 will work) or carb Cleaner NOT starting fluid (to explosive).
