Who is Number 1?

This is a cross post from k-bikes. Nobody seems to know the answer there

I have just done a valve check on my '08 K1200GT. Turned out a lot easier than I thought and they were all in spec at 18k.

My question is which cylinder is number 1?
It doesn't really matter for the valve check, but I am curious. WIth the camshaft marks lined up flush with the cylinder head surface, 1 and 4 are at TDC. So, which is which? It doesn't tell you in the RepRom.

Cool Re: Who is Number 1?

Don't know the GT but if they follow industry standards it would be from left to right as you straddle the Bike. It is from front to rear if the cylinders are in line with the frame, like on the LT.

HTH,

BMW knows nothing of "industry standards"! If BMW did not invent it, it does not exist.

I have a BMW car with a V8, and found that they number the cylinders from front to back as normal, but 1,2,3 and 4 are the left bank, 5,6,7 and 8 on the right bank. All theV8's I ever worked on before were in order of the cylinders on the crankshaft, so they alternated left to right, with 1,3,5 and 7 on the left, 2,4,6 and 8 on the right.

I thought BMW was strange at times, until I bought a Toyota Tundra truck with a V8. This one is stranger yet, with the water pump driven by the TIMING BELT, so you have to remove just about the whole front of the engine to get to it, and the starter is UNDER THE INTAKE MANIFOLD! In the past I thought Toyota was the best about thinking of mechanics who have to work on them, but now there is a group of engineers sitting at their desks in Japan laughing until they cry.

For an old mechanic/engineer like myself, nothing seems to be sacred any more!

I don't want to achieve immortality through my work...I want to achieve it through not dying.

Ding Ding! Looks like we have a winner. Thanks, Steve. That must be somewhere in the RepRom. I'll look harder.

That was what I initially thought, but the camshaft drive on the right side threw me.
It would be nice if they all numbered in the crankshaft sequence with the front being the opposite end of the drive side.

And my flat-6 Boxster is numbered 1-3 on the right and 4-6 on the left!

Re: Who is Number 1?

Ford V8's were numbered 1-4, 5-8. Firing order was therefore different, but turned out to be the same if you numbered the cylinders like GM or Chrysler.
