I hate to be that guy that signs up only to ask for help, but I am at my wits end. I am working on a 2000 DS650 that quit running after the rider dumped the clutch repeatedly.
I had to fix a few things to get where I am now, cranks but doesn't start.
New starter clutch
New CDI
New coils
New trigger coil set at .003
New spark plugs set at .026
New rectifier
Verified TDC, used locking bolt and pulled cam cover to verify valve timing which seems good. While I had it locked at TDC, I did a compression leakdown test which showed a loss of only 4@100psi
Compression test shows about 112#
Carb had clean gas, but pulled jet and blew through passages, all clear and clean
All this thing does is spin. Nice, bluish/white spark at the plugs, added fuel through spark plug hole and used ether, both failed, not even a hiccup or fart, just keeps spinning.
Someone please give me some ideas here before I pull out my gray hair?!
