The manual helpfully gives this guide to timing setting.

However it is a little vague as the wording can be read 2 ways.

Looking at a wheel imagine I have TDC at 0 degrees (straight up/north). My missing tooth (#1) is down to the left at say 270 degrees/west.

My pickup is at 90 degrees/east.

So I rotate the wheel from TDC to the first tooth/pickup alignment point.

My trigger wheel has only rotated 180 degrees (west to east) to make the line up, but the angular position from TDC for tooth #1 is now from North to east so 270 degrees.

Which figure do I put in the trigger setting, 180 or 270?

The location of your TDC pointer or marks are irrelevant. If you read that first sentence again, you'll see that TDC has nothing to do with it, except that the process begins at TDC. Set the engine at TDC however you can. Now rotate the crank until the 1st tooth after the gap is under the sensor. How many degrees did it rotate? That's your value.

PSIG,

Thanks for clarifying and that is how I read (and set my timing).

The only reason I asked was on a recent tune setting I accidentally sent the number higher and the bike still fired up and then I began to doubt myself.

rereading the wording still kinda gives two options but your confirmation is clear.

Thanks
