No trouble going from 2nd to 3rd, 4th, etc. Only from 2nd to 1st. Riding in 2nd, I would pull the clutch lever all the way, press down on the shifter, and the lever would go down, but the transmission would not shift into 1st. I tried re-engaging the clutch, even giving it some gas, and then try downshifting again, but nothing.

Weird thing is that the problem was inconsistent. One stop light it wouldn't work. 2 minutes later at the next light everything shifts fine. 4 minutes later at the next light again no downshift.

For reference, I only have 1650 miles on my s10, of which I put on the last 700 miles. I didn't abuse the bike at all and mileage is really low for transmission failure.

From a quick search online I saw comments on oil and the shift pivot bolt. Modern oil is modern oil is modern oil, but who knows what the PO put in so I changed that out with a Bosch 3300 filter and Rotella T6. I would prefer an oem filter, but it's Sunday so I'm stuck with whatever is available from the local auto supply store. I haven't taken the s10 off-road yet so the shift pivot bolt was clean, but I wiped it off and relubed anyway.

Took the bike out for a 15 minute shakedown and the problem seems to be resolved and shifting is a bit smoother. If it comes up again, I'm taking it to the dealer and using the extended warranty.
FWIW, I have experienced similar to this when oil got old. Do you know for certain that the six hundred mile service, with an oil change, was done?
