This is a really bad idea right?

OK so a while back I posted about a chain alignment problem on my '82 atc 110. After much investigation, I think that my problem is due to a tweaked frame. The front of the sprocket is closer to the frame than the back, and I can see the same forces at work on the brake drum cover on the opposite side.

Is it absolutely nuts to take a big 5ft bar and put it in the place of the axle shaft and try to make a slight adjustment? I'm sure that there are lots of reasons not to do this, but without totally swapping frames, I don't see too many options. What is the consensus of the group on my best bet here?

I do happen to have a spare atc 90 frame. That would be the same right? How tough would it be to switch everything over? I appreciate your ideas and suggestions.

It all depends what you pry on. For example, you dont want to pry on anything where there are bearings because you could ruin the bearings. Pics would help with a more accurate response. Shock may also be an option. Smash it into a wall, hahaha.
My friends atc185's front forks (no shocks) were bent from someone hitting a wall head on...So he strapped the back to his shop and the forks to his truck and gave it a pull, straightened it right up.

As long as the bearings arent destroyed, i would say go at it!
Wait for more responses. More educated people are on here.
GOOD LUCK!

Maybe the frame's ok?
Any paint kinks?

I'd get a free manual from the world class help section and download
parts pix from bikebandit.com and see if some shims or spacers are missing
from the rear axle assembly.

I braced a frame between two pillars in a parking garage and then just applied pressure with a
bottle jack laying on it's side. (lots of 4x4's, and lumber cribbing)
Press was very controlled and actually worked.

maybe you've got the wrong sprocket with the wrong offsett???

just swap the frame its not hard. there aint much to them.

If you are going to "tweek" the frame I suggest heat and then some gussets afterwards as your frame will likley return to the bent possition after a few hard hits. I suggest you find someone in the automotive frame straightening buisness that also rides bikes to help you with this, or a good welder fitter, key word FITTER.

I feel like the mechanical parts of swapping the frame are pretty straightforward and can be accomplished with the aid of the manual. The part I'm worried about is the electrical. My 110 is a cdi trike and the 90 obviously had points etc. Is there anything that I need to watch out for or do if I try this. This obviously is not something covered in any manual.

Simple, just swap all of the electrical over as well.
