Gear Grinding

This may have been brought up before, but my 1968 TR6R grinds gears when I shift from neutral to first. It shifts smoothly when I go from second gear to first. Is this normal?

Some do grind a little bit going into first. If you are sitting still in neutral, one shaft is turning , the other is not. When you try to put it in gear, you have the dogs (ears?) on one first gear spinning past the stationary dogs of the other so they strike each other a bit until they get engaged. Once you are rolling, the shafts and gears are both spinning so the gears engage easier. If it lurches or creeps in first gear with the clutch in, an adjustment may be in order.

Keep your engine idle low. If the cluch adj, checks ok you may want to shift into neutral befor stopping and keep the cluch lever in. Before you take off shift into second then first. I had a 67 that was bad for that, and sold it before ever fixing it. My current bike does it when it's cold, then as the engine warms up, I screw the idle down. 1 carb, can't beat em.

I've never had a Triumph that didn't do this most of the time. A lower idle helps but in many cases, especially with twin carbs, this is difficult to achieve.

If it's grinding when shifting into 1st after starting, it may be because the clutch plates are stuck together. You probably know you can free them before starting by kicking the starter with the clutch lever pulled in. It'll crunch a little anyway of course.
