Tell us more.

What is not centered?

Do you have clearance on both sides of the swingarm?

It is normal to have more clearance on the brake side of the swing arm, but I just checked and it is just about centered in the fender.

Give us more inof.

back wheel is not in center of the bike, lots of clearance right side but almost no clearance on left (drive hub side) but if you look at the bike from the back of the bike, the whole tire is on the right side of the fender like half an inch off center.

Is the spacer between the caliper bracket and wheel in place?

If you got a 280 on that 10" rim, it is normal for there to be very little clearance between the tire and the swing arm on the hub side.

So that side sounds normal.

If you are 1/2" to the right in the fender, I am thinking that spacer.

get us some pictures.

That's normal. Even on the stock set up one side has 3/8 maybe more then the other. You just noticing it more now since you filled it out with the 280. Ppl running a 300 only have a 1/16 even less on one side an 3/8 on the other.

Spacer in the hub wont do this , if the spacer on the caliper side was left out the disc will bind on the caliper .

I have had that the rear fender can be as much as 3/4 inch off center , this could also be what you are seeing !!

I'm no expert, but it seems to me the handling wouldn't feel right going in a straight line...with that much of an offset, the rear tire can't possibly be tracking in the same line as the front. I'm surprised your not going down the road sideways...:dontknow:

:dontknow: here is pic
I should have been more specific in the picture request.

Give us a shot of
-hub side - top down
-brake side - top down

I am looking for the clearances at the swing arm and to confirm the spacers and junk are there.

It if is good in the swing arm, then you may have a fender out of line.

Looks normal in the swing arm.

Did they take the rear fender off at any point?

Are any of the covers below the seat looking out of line?

NORMAL .
Dragon , go with the search engine and read the
thread posted by "Dam Guy " called " 10 inch rim 300 tire"
you will see that he modded his swingarm to have 12 3/4 inches
between the swingarm forks ,and when he installed the 10
inch rim it would rub on the driveshaft side , if you have
a 300, the shop that installed your rim shimmed it to
correct that , , or it is just normal for the 280 to be very
close on left side if they did not adjust anything.
==============
I haven't done the 300 mod yet ,but I try to read everything
that is posted on the subject . Funny how most times the members
who have done this mod with success will not post the
solutions in an actual thread but instead they write
"will PM you the solution" .
I made a file with pictures of the modded inner fender ,
modded swingarm , or DLP swingarm , 300 tire ,280 tire,
many threads on this subject all over the place.

He says his bike is "doggy tracking", aka "crabbing". How can that be normal? And if this is normal with a 300 back there, and it causes the midline of the bike to be canted at an angle to the direction of travel, why would anyone want that?

Even if the rim was as much as 3/4 off it will not "crab" the only time it will crab is if the rear wheel is not 100% inline with front , meaning that the distance of the axle on left or right is not the same distance , follow ??? ok if the swing arm was bent or the swingarm bolt where it attaches to the frame was bent ot out of line .

That rear fender seems a bit "**** eyed " to me !! I have found that on some of the 109's the rear frame rail , where the chrome arms that go below the seat are attached to are as much as 1/4 " off , going further back that could throw you off as much as 1/2 to 3/4 "
i would say that fender is not lined 100% wheel and rim seems fine

if you could run a straight endge forward off the rear rim from the left side and make a mark beside the front wheel , then do the the same on the right and measure the distance each side of the front wheel you would see if it were out of line .

rear rim 10" front 3.5 there fore you should have 6.5 half to either side of the front rim , 3.25 on eah side , if you do not get that there is a problem !!!

Exactly , "he says....."
I think it is not crabbing ,but Im1dragon figured he was crabbing ,
when he looked at different clearances on both sides .
--------------------
if rear wheel is mounted wrong , it is pointing in different
direction compared to front wheel ,then you really feel it.
