I would check alignment of rear to front tire just for the hell of it.

Yep. I know its been down on the right side but I dont think it was hard enough to torque the neck? Could be a frame defect? Ima break out the laser n see what I can find. Aint gonna lie, Im kinda scared, after some of the other issues Ive run into. :oldlaugh:

Found the same thing on my last front Shinko. Pretty sure it was an alignment error on my part as the rear (Shinko) was worn in a similar pattern (off center). Re-aligned the darn thing and am checking out regularly now. Still buying Shinkos because I couldn’t find reasonably priced Avons.
Please let us know what you find.

I used my usual method of lining up the new rear. I center punch the axle bolts an use calipers from there to the frame. I try to keep it within .010-.020 side to side, but I gotta figure where I went wrong? Swingarm may off a tic? I hope its just my incompetence...?

Roger made a tool out of some heavy wire that measures the distance from the rear axle (#20 both sides already center punched) on the K9) to the swingarm pivot (above the kickstand-#3). He took a bolt that fit perfectly in the recess (#3) and drilled a center hole in the head of the bolt. Equal measure means the that the rear swingarm is centered with the frame (check swingarm for any play).
Of course the front fork could be tweaked, but I’d think one would recall anything violent enough to change the geometry of the front fork—like a collision or deep pothole. I think Paul Knowles is correct—check front to rear alignment.
Again, I’m pretty sure my issue was due to my error. As I recall the rear tire had excessive wear left of center and the front was on the right. Replaced the tires, so any wear will be apparent after our run to Galveston early Nov. for the Lone Star Rally.

So, I throw a laser on the rear and the overall alignment seems to be pretty close. However as I was looking @ the rear tire I noticed the swingarm didnt seem to look the same side to side. Quick measurement from the ground to the center of the rear swingarm....1/4" difference! Left side is lower. Hmmm. Time to dig in I suppose. Gonna get chilly here soon anyways.

Always get more wear on the right side due to road crown and RH turns are longer.
Most don’t notice because they would have changed that tire 100,000 miles ago

Hahaha....it was fairly fresh when I changed the rear. That was just before Dave's in Sept. I havent put that many miles on it...since I got it maybe 2500? I woulda figured road crown would be wear on the left side? We aint got many RH turns here either.....ride straight, stop, turn right. Kansas kinda straight n flat where I live. Only right handers are roundabouts and I only do two laps on them!;)
edit: well shit, roundabouts are lefts! My bad. Maybe its the extra laps?

Yes, correction road crown wears left side sorry, was looking at that backwards obviously, I was too busy trying to be a smart a$$ lol.

If you only got 2500 something is off for sure.

I usually replace my front every other rear, and get 6-8k out of rear. I use Shinko front and rear too.

Are the forks racked, neck bearings?
