I've been in touch with Charlie, tried the sanding with no results, the wrist pin and bearing work fine in the other 2 rods, pulling the crank back out and sending back to him. It's a sad day in my world. |

Yes, I imagine it is a sad day. I'll be very interested in what the problem is. I'm sure you will too. |

My crank is on the way back to me, it's still a head scratcher, Charlie said out of 700+ cranks he's rebuilt, he had never seen this. I sent the bearing and wrist pin with the crank, he was able to clean it up but never found any sign of damage to the rod after putting it under the scope. He ask where I got my needle bearings, I told him from a reputable vendor, he said he likes the original bearings but is sending me a set of new bearings that he uses. If you look at the original bearings vs. the bearings on the market, you will notice the needles are longer on the originals, covering more surface area in the rod. Here's a pic of the original vs. the new ones I bought, original on the left, I should be headed in the right direction in a couple days, big thumbs up to Charlie for going above and beyond on the quick turn around.

A little more progress today, got the rotor and stator mounted, cleaned the points, carbs are in sync now, never ordered any head pipes, they cleaned up better than I expected. Attachment: H1 progress.JPG

Double check the top end bearing size, that bearing looks small. Or the pin is too big. Oops, I'm a bit late. |

My tins have been at the paint shop for a month, I told him no hurry, but damn.
