My yamaha timberwolf 250 4x4 (unsure the exact year) wity the clutch less manual transmission will shift into the diffrent gears but will not engage 1-5, but will engage reverse. So it knows its in first but won't move forward. Reverse is immediate and will move. 1-5 act like neutral. Is there any adjustments pionts for the transmission. I have located the clutch adjustment but nothing changes.
