Chain guides
 

What is the difference between the black and brown chain guides and why? I assume it's more than just the colour. It's just one of those things I have to know.

The shape and length are slightly different.

The brown is shorter than the black

The brown ones are, if my memory serves me, supposed to be mounted nearest to the center of the engine.
The point is, they need to be put in the right place. Autotuning in norway will know for sure....

It has been my understanding that there are 5 Black and 1 Brown.
Have I been mis-informed?
It has been a while since I looked at mine (lazy...could walk downstairs to the shop and look).

That's right. I always wondered if there was something special about the material of the brown one. Seemed strange that if they just wanted the color as an identifier they'd make the variance more obvious.

It makes sense that two almost similar geometric shapes are differentiated by colour. I have not compared the two types enough to notice that they are not alike; I have just accepted the fact that they need to be installed at their specific position. Does anyone have any thoughts on any differences in material?

There is only one brown one. It goes on the right lower position. It is taller than the other black ones and I believe made of a harder material. In other words, it holds the chain up a little more because of the way the chain comes off that right tensioner sprocket. The clockwise rotation of the chain coming off the right sprocket tends to lift the chain a little and I also believe fast on & off throttle blips tends to put a harder load on the brown ramp. I could be way off on this, but it's what I think. Waiting for the multiple corrections......

The brown guide uses the ground-up seed of the noslackum nut that is grown for this very purpose on the hill overlooking the Karussell turn on the famous Nurburgring. The amazing qualities of this seed material have not been duplicated in the laboratory. Among its traits are that it is extremely hard, impervious to high-temperature oil, and when rubbed by a double-row chain, it produces a harmonic tone that can only be described as a combination of angels singing in a chorus and the staccato of 100 MP-40 machine pistols firing on full automatic.

I don't know anything about the black ones.

Is that on the east or west side of the Karusell?

I had to go down to the gun locker to verify, but on my MP40 there is no select for "single shot"....just the trigger....and a very crude "safety" ( you place the bolt all the way back in a side slot).
And wouldn't 100 of them bring the law into the situation?
Or do you think they would simply write it off as a bunch of people celebrating?

The brown has a slightly lower profile than the black ramps and the lengths are the same. The brown ramp position is bottom right (the only ramp on the bottom right) next to crank.

I hope that helps.
