Hey folks;

I've noticed that the PA50 feels a bit odd when ridden, so I decided to have a look at the alignment. The front half of the rear wheel was slightly to the right. The only way I could see to correct this was to push the right-hand side axle adjustment forward a bit.

So now, the wheel appears to be straight, but the hash marks on the axle adjustments no longer match on the left and right.

There's no visible bends or cracks in the subframe.

So am I stuck replacing a subframe, leaving the axle adjusted as-is, or ?

PS: Anyone think adjusting the engine/subframe bolts would help?

Align the wheel, leave the damn thing alone. Not every one is perfect, that is why it is adjustable. The engine is not adjustable.

Thanks. I was worried that pushing the adjustment so far in difference would do something weird to the gearbox bearings or whatever. The simplicity of my 40V has me spoiled :D (edited)

The top bolts on the swing arm are square to each other with the motor mounts. The bottom slots are not. Because of the different components, vario on one side and brake plate on the other,, the brake plate side of the swing arm is about 1/2" shorter on the adjuster.

Did you just say Motobecane and simplicity in the same sentence?

Hey, 40V has no swing arm or gearbox, just a screw adjuster :D

Not so bad once you have good engine mounts... and rebuild the engine... and reshim the variator...and fix the electrical switches...and relube the fork dampers... replace the special "honeycomb" brake shoes...replace the rotting fork rubbers... throw away the shitty carb...

Okay, maybe a few issues :D

Yeah, I set up the "string" method for checking alignment. Straightened out the back wheel, tightened it up. Now it doesn't feel squirrelly when I ride down the road

I thought I was going mental. Every time I rode in a straight line for long it felt like my ass was going to change lanes without me
