New clutch plates and still will not pull itsself...help

may be clutch plates you purchased doesn't march with the original one, or may be you have not replaced all plates (you dicided to change some of clutch plates not all)

Sounds like your clutch is slipping. Make sure your clutch lever has free play of at least a 1/2 inch. Otherwise it is time for a new clutch. Although at 15000 mi it should not need one yet.

Sounds like its time for some new clutches.You can try to adjust it to where you have a lil slack in the lever,which MAY help,but most llikely its clutch plates time.
Good Luck!

Is choke engaged and working?
Are all plugs clean / new?
Is petrol fresh?
Are compressions OK?

all you do is drain the oil before removing the right hand engine casing the bigger one of the two then undo all the little bolts holding the small springs in place then rmove the face plate and take out the clutch plates and replace with new ones remember to put the new ones in the same order the old ones came out there should always be a friction plate between clutch plates once done put casing back and refill with new oil
hope this helps

just take side casing off and u will c a round clutch basket take the retaining nuts out about 6 or 8 ov them and tenshion springs take all clutch plates out with other discs and put new in in same order nothing can go wrong. hope this is helpfull

Real easy, just drain oil, take off side case and remove the bolts.
Take it off as an assembly.
Make sure clutch plates and friction plates are positioned correctly.

Are you sure you need to replace the clutch?
I assume it merely needs a minor adjustment.
