Agreed on the materials quality and care taken in assembly as a big factor, but (in bold) you've hit upon the crux of my question. When cheap cranks fail, is it the shaft or the bearings in which it rides? I guess it's a moot point, unless one can improve the reliability of a Taiwanese crankshaft simply by fitting better bearings.I have ALWAYS heard from the Hawaiian "808" guys about the stock Honda AF16 cranks' reliability / durability. Evidently the stock crank & conrod can handle some high RPM's as well (or would it be those Honda bearings...hmm) My guess is that the Honda crank is absolutely PERFECTLY balanced, they are probably pressed together tighter, use better needle bearings and shims, and are made from a slightly higher quality metal.
I believe the Ruima is advertised as a 44.1 stroke. You'd think the stroke would be a dead-simple thing to measure, even with primitive Wheelman rock-and-stick toolkit. A couple of v-blocks and the depth gauge on a digital caliper...-The SEF crank is cool because it is not quite a "mini-stroker" crank; it's stroke is between a stock stroke and a 44.4 mini-stroker. No one in Hawaii quite knows the actual stroke of it....
You do me too much honor. Just havin' fun boltin' up parts in the Boudoir. The poor quality of my pictures hides many flaws...Anyways, keep us posted on your progress, Guy. You always do some really accurate, spot-on builds
SA50 service manual page 10-5 has is - 'After '93: 5.0mm (0.20 in)'No matter, my little flywheel puller also works great. Doesn't disturb the crank bearings. Anyone have access to the depth necessary to drive those seals? It was 9mm for one side on the AF05, but I can't access the specs for the 16 on BB.
