Antietam Classic Cycle:

Getting back to the front axle spacer. What was Guzzi's thought process with regards to the left bearing being a "floating" bearing? I took the front hub apart yesterday and the spacer my buddy made came out to 70.22mm. My buddy Gil was with me and I decided to just make a 6mm spacer from the leftover McMaster-Carr tube and reinstall it. Gil asked why couldn't we just leave everything the same, bearing in place with the snap ring like the right side, and put the 6mm spacer on the outside of the left bearing? This will allow the front axle to still seat at the proper distance.....unless Guzzi decided the wider stance of the bearing is needed for stability or tracking reasons. Thought's?

I've been asked that question more than once and really don't have a good answer. If Lino Tonti was still alive we could ask him...

I spoke with Greg at This Old Tractor and he said about the same. He stated he didn't think the 6mm difference was that big of a deal and to try it with the bearing snap-ringed in place, so that's what I'm going to do, I made a 6mm spacer so I'll put that on the outside of the bearing between the nearing and axle....easy enough to reverse it if needed down the road.

I tore into the transmission last week to check how things were, since I can't trust anything the previous owners did. All the proper spacing worked out pretty go, except the layshaft is .011" short, if I can leave it I'll leave it. The two shift forks show some wear, like .010" (Striker fork 1-2-3-4 gear forks) 14230501. I found one for sale but I'm not paying $300 for one fork....or even two....KMA! I may have the welded and re-ground, I have people that can do that. Is .010" in tolerance? I couldn't find a spec on minimum thickness.
Installed the rebuilt front forks on Saturday...YAY! Finally! The forks were bent a little but the triple tree was also bent, nothing lined up. Thanks to Charlie for offering up a straight lower tree but we got it straightened. So I installed new progressive would springs from MGCycle, along with damper inserts. Had to buy a tap/die set for the two top fork plugs and had to straighten some other parts from improper installation by the cavemen.
Also installed the rebuilt front caliper and master cylinder but need a 90 degree banjo coming off the master cylinder, didn't like how it was originally routing the brake line, so I have that coming. Later guys! I'll get pictures once I sync my phone to my PC.

This is exactly what I ran into with my fork delima, I finally got straightened away. So next time your triple tree is out, check it for straightness. https://youtu.be/ZX1fXmeTbAk?si=07SajviHcKg1TuqS Since the bike showed no signs of a crash, I wonder if they were coming out of the factory like this. These lower triples are strong, so being bent in an accident would take a lot, since the fork tube are much softer and take most of the impact, me thinks.
