If you used motorcycle oil then I'd doubt that's the problem. Keep in mind the tranny won't shift as well with the engine off, or even with the wheels stopped. Especially down shifting to 1ST. Try putting it on the center stand and rotate the wheel while changing gears, or double clutching. If you were having trouble up shifting while riding the bike then I'd guess your shift forks are shot, though it could be worn dogs. Keep in mind I'm just a shade tree guy, who didn't sleep in a Holiday Inn Express, so YMMV. Sent via BlackBerry by AT&T

Ron, I read through that discussion. Being new to motorcycles, I wasn't aware that oil made such a huge difference--well, not for the transmission anyway. I can drain and get new oil and filter, per your suggestion. If this is all that it is, I'd be very happy. I'm seldom that lucky tho. Thanks for your suggestion.
