I kept this a secret, lest I jinx my recent purchase. I've had my lesson with the ill-fated Wild Lion That Never Was from Malossi USA. Anyhow these:
Showed up as promised via UPS tonight. Well, almost as promised. They were supposed to be new, but they were dripping with gear oil (that unmistakable aroma of Crusty's Garage...) and a few flecks of red paint for some reason. The Husky countershaft sits in its #4 gear there on the left. The seller even forgot to remove the shim washer, which was stuck to the countershaft gear! No matter, they're not worn as far as the eye can see, and they're - get this! - 20 x 36.
That's right, you read correctly. 20 x 36 Secondaries
. I had the seller throw in a used Elite axle for an extra couple of bucks. I'll have Honda-san press the stock #4 gear off and install the 36- (counted 'em!)-tooth axle gear manana. The axle is the "early" one with the shaft end cut for a 6303 bearing, just like Flash 4's cover. Quick-change ratio swaps.
Combined with the 12/42 primaries, this yields a 6.3:1 final drive ratio. What remains to be seen is if Flash 4 has the torque to drive these babies off the line. Or up hills. One thing's for sure, top speed should go up a bit, as long as there's light rollers in the vario and/or a tailwind.
Mouse, could you add this option to the spreadsheet? Not sure where they came from, not sure if they're still available, but I lucked out on eBay this time.
