The clutch on the 650 has to be let almost all the way out before it engages. Their are some fixes for it. One is the (Cleaver Lever) and the other is the (Seritec) which is a spring/tube device which works very well. Both have web sites.seems like i have to let the clutch out alot on my bike..is there any adjustment to cure this? it has only a little over 8000 miles is all..i wish i had a manual for it but can not find one anywhere..if anyone can help me here i will appreciate it very much...john
