Anyone thought of this frame mod??

I was contemplating my engine shift for the stator replacement.
Then I started thinking about the removable frame section on the clutch side of the bike.
Has anyone ever heard of or seen the frame made to have a removable section on the stator side?
Are there any major concerns anyone can share about this idea?
I have access to all the material and equipment to do this, just wondering what everyone thinks about it. Seems it would be cheaper than a modded stator cover, though it would still require an initial engine removal.

Any/all input is appreciated.

Having mine apart in the garage right now, I don't understand why the left side wasn't the removeable section instead.

It would make short order of a stator change. What on earth were the Kaw engineerings thingk about

Clutch changes. I believe their thinking was that the clutch would need to be replaced more often than the stator. Unfortunatlely, they were wrong but did nothing to correct the problem.

We've talked about putting in a sub-frame on the left side. The one consideration would be re-enforcing the break points so the frame is still solid.
Believe the frame is hollow tube, one thought was to insert a core slug that the parts bolted through. The other was to form a collar around the two cuts. Third option was to do both.
The left side has offsetting tabs that bolt together, so another option would be to cut out a section at both places and weld in the tabs that would bolt together.

Ummm.. so yeah, we've thought about it!

Oh yeah, couple of other things...
I don't think the sub frame on the left would have to be as big as the one on the right. Main area of concentration is the stator cover, you only need to be able to pull that off, so just the lower bend area and along the bottom.
Secondly you would need to pay attention to your peg mounts etc that go along that section and try and leave that area intact.
You also want to make sure that it goes back solid and can hold up to any vibration.

There, how's that for a few thoughts!

ehh, i thought about it... then relized that it wasnt worth the major R&D and welding. i guess you could just pull the subframe off a junker, and cut and put tabs on the right.... I dunno. I just went got a TOC cover. I think that should have been the right approach from Kawasaki in the first place....

That's what I was thinkin', making it very similar to the clutch side.

I have a bar of Titanium that was left over from a job at work that would certainly hold up, just gotta see what the possibilities of that being welded to the frame are.
And if that's not doable, I'd probably go with stainless steel pieces. I could even get the entire subframe part, with the bend, made from stainless tubing. or maybe even solid bar stock.

Right now it's just something I was thinking about. I haven't even ordered a stator, or tested the R/R yet, so I'm not in a hurry. With the sub 30 temps we've been having, it looks like I'll have plenty of time now.

The one thing that concerned me most was if the frame might twist if it's cut.

Thanks for the thoughts on this folks .
If anyone has anything else to add, feel free.

i have a frame in at the moment and that is just what we are doing twin removable downtubes (makes engine removal easier and for minor jobs unnesesary) will let you know how it turnes out and post some pics, to show what reinforcing / bracing was needed (if nesesary)

Sound great.
I wouldn't think it'd be too difficult. Good luck on your mod, and I 'll be waiting to see/hear how it goes.
