spline between drive shaft and rear gear.

the transmissions on these are solid (other than the shift rod issues earlier years may have had). possible clutch problem, but new parts for that (other than disks, friction plates, springs) are pricey.

Agreed, rear splines a very good possibility. 20 minutes to pull the rear wheel and final drive, and you'll know.

edit: Alternative to pulling the final drive .... Peel back the rubber boot, at the front of drive shaft behind bevel gear case, watch the drive shaft while spinning the rear wheel. Or engage 1st gear, let the clutch out while watching drive shaft.

I had a hard time getting that boot back on, took two of us.

ok so a mechanic had it for a month, didnt even bother to really look it over. anyways it only stays in neutral, will start and run just fine. will not engage into any gears. theres no oil in reservoir, pretty sure theres a hole in it somewhere. are we talking just a busted clutch assembly? he didnt want to take apart the engine which he'll have too to get to the bottom part? idk im not buying another bike. its mine out right, what can i do to combat this situation?

take it too another mechanic. any mechanic who takes a month to even barely look at it is not interested in really fixing the bike. also so, there is no oil in reservoir?? and he is running the engine?? since the engine oil IS the oil for the transmission, clutch and everything else there, he dont know what the hell he is doing.

to check the following items it should take a total of an hour...

rear splines, about 20 mins using the pull rear tire and final drive method.
clutch, about 20 mins, maybe less. this is only 6 or 8 bolts, and only one is SLIGHTLY hard to get too due to exhaust pipe.
