I have just found that it is the crank to rod bearings knocking by the sound of it, as it has got worse and more noticable.

If honda standard colour code is green, then the other three cylinders are not going to have bearings in that are big enough, right?

I mean, black and red must have bigger bearings if the re-grinded crank is smaller.

So, ive ordered some plasti-gauge to check the tolerances and im just going to buy honda shells the correct colour code.

My main question is, Does anybody know the tolerance of the colours?

How big/thick etc is green for example??

Thanks for any help
