Morning All, I have a 2018 ONE 250 which I've owned from new. For as long as I can remember it will not shift into 2nd gear when cold. It will half select the gear and 'grind' lightly. After running in 1st for a few minutes to warm up, it shifts ok. No issues engaging any of the other gears once warm. I've tried a few different oils, with no improvement. I change the oil frequently and nothing of concern on the plug magnet.
With the engine off and cold, it will not shift into 1st or 2nd, with or without the clutch.
Any suggestions? Thanks
