I'll repost specs when I put my jamarcol with large ID header back on and hopefully get to 45. With a C and a jarmacol (everything else the same) I was seeing 41mph, so I'm not too impressed with the gianelli. Welded custom brackets to the gianelli to mount on the engine bolts. If I put the jamarcol back on, I'm using aluminum spacers instead of bushings. Bushings + hard frame mounted pipe = ripped out exhaust sleeve thingy

Checked for leaks with both propane and carb cleaner but couldn't find one. I will continue to run it and keep checking the plug but it feels just about dialed in. The top speed showed 45 on the stock gauge. GPS gave me a top speed of 42.

I was given a set of A3 clutch shoes and modified the A35 clutch plate to accept them, at the time it was an experiment to help me avoid buying/finding the A35 replacement. The case has been cleaned, flushed, and sealed back up with a thin RTV/Gasket sandwich, thin layer of RTV gasket more RTV, fixed my leak issue. Since the rebuild I have switched transmission fluid to 250ml Dexron Mercon + 150ml 85w-140 Gear Oil + 100ml AT-F fluid = 500ml total. Will be switching back to a full 700ml mixture of the Dexron/Gear Oil in a 50/50 ratio as the pickup was marked for such a stock bike. However with both mixtures the 'automatic' in the automatic transmission is 'not engaged', the 700ml mixture allowed/forced me to manually (easing the throttle down) shift into 2nd gear at the peak of it's power then bring it to top speed by drawing the throttle from 3/4-WOT. The stock carb kept up velocity during the shift but I plan on downjetting as idle requires some throttle work to stabilize. The plan is to have some fun getting from stoplight A to stoplight B, it feels maybe 90% there. We'll see.Can't thank you enough for the resource. It has been a huge help to us here in the Spark Shop! Only technical concern is the visual organization of the sheet, It's hard to get a view of several comparable bikes on one screen without zooming way out and squinting. If I have any ideas I will be sure to email them to you or come up with a layout that could address 'dis sheet. Good luck dudes, keep up the good work! HBH! HOOEEWWWWWWLLLL!
