Hi there, nice to find this site! I found the project bike pictured in Germany last summer and just started to re-assemble. It will slowly but safely go back to a more original shape, but I will likely keep it in the Café racer style since I have other british and japanese bikes that are original, or as close as it gets.
I am replacing some parts in the engine, for example a had a tooth missing on one of the gears in the gearbox, also some damages from a chain failure and "human bad treatment/habits" that eventually made me replace the cases to another very good set of used ones instead of spending time/money repairing the old ones. I took interest in reading the posts about crank bearing sizes. My conclusion is that my degree of confusion about the color coding of the shells, is not exclusive for me.
Still, I would like to do this by the book, and therefore, I tried to get some sense out of the case markings discussed. How can these be translated to a measure, or other data that can relate to bearing shell size.
Can the numbers (Dont make any sense to me in the form they are displayed) be translated to the bore of the bearing shell seat bore? (Like 36.005 mm)
Looking in the manual, it seems fairly simple without using any stamped-on data, just to measure the bore of the bearing seats when the cases are bolted together and then that size will be wíthin the ranges listed in the manual, corresponding to the color codings of the various bearing shells listed. Or am I wrong?
