It will be useful to know when setting the firing order to 1-8-4-3-6-5-7-2.

I consider the left (drive side) to be #1 same as any multi cylinder bike.

#1 is next to the radiator
and #8 at the back by the gearbox
now normally the radiator is in front of the timing fan belts, which I guess suggests #1 is the T/S
On the groups triples the timing marks typically designate the T/S piston at TDC

Think I'd settle for the left or the right cylinder on a twin, and before you ask the left is as sitting on the bike or the side with the sidecar on it in UK

Soooooo Olev, seeing as the water goes down the plughole in your neck of the woods the wrong way then everything needs to be reversed, is that where I'm going wrong
