Trouble started last weekend, got gas. Left the gas station, couldn't shift from 3rd to 4th. It was like it was in 5th gear the shifter will not move without breaking something. Give it a minute and it shifts like nothing was wrong. Down shift then up shift and all is fine. Does it from 2nd to 3rd, and 3rd to 4th. But not all the time, and it doesn't matter if you short shift and go easy, or hammer on it. So I changed the clutches, changed the oil and filter. All was fine. Then the next day same thing. But it doesn't do it all the time, lol. It might do it twice in a 100 mile ride, or it'll do it 12 times. And I have no neutral light on the tach, but it shows neutral on the indicator. Pulled the sensor when I changed the oil, clean. Still no light. I voided the warranty when I installed the DD mod, lol. And the trans. Only seems to act up when it's hot. Running Valvoline full synthetic 10w40 motorcycle oil.... Was gonna change it again to shell rotella T4 15W40 and see if they helps. No unusual noises, shifts smooth when it does let you shift.... And chopping the throttle with or without the clutch makes no difference, it will not shift.
