I may need to put this on video, but when my rear tires are jacked up off the ground. And I pull clutch all the way in and then shift to 1st gear, should the rear tires rotate at all? Mine spin around like 2 revolutions and then stop? And I also noticed when unit it off and rear tires in the air, while in gear and clutch pulled in, tires don’t spin near as easy as if in neutral. Does this sound like clutch is out of adjustment, and if so any tips on which way to adjust, tighten I'd guess? Thanks for any info, or input.
