Good luck.
I agree, flipping the swing arm is a major operation. You would have to relocate the shock mount which is an absolutely critical part, as well as figuring out something for the upside-down brake caliper and chain guide. Way too much work, and I think it can be solved differently.

Some welding will definitely be needed for the brake caliper carrier locating pin (or what ever you call that bracket that you slide the carrier on from the back). This is not the only problem though, as the carrier and caliper would be the mirror image of what you need, facing the wrong direction.

I thought about two possible solutions for this:
- Use an EXC carrier/caliper. They are left hand drive and use the same hub (20mm axle) and 220mm brake disc as the LC4.
- Use a DR650 carrier/caliper. Left hand drive as well, 20mm axle. Made for a 240mm brake disc, which can be solved by using a 950/990 disc (240mm) on the LC4 wheel (same bolt circle). This along with custom spacers was the solution for running KTM wheels on my DR.

I should still have a Duke swing arm somewhere in the garage (I assume this is similar to the LC4 one), and will try to work this out when we get our EXC back.

That's a good suggestion, and something I have considered as well. Always loved the idea of a swing arm so wide that it would allow 5.5" rim, as I could then also run a supermoto wheel set with the left over 180 tires from my track bike.

My concern was the material the swing arm was made of, and how I (or rather a buddy) could weld on the carrier locting pin. I know that it's cast, which makes it difficult either way. But I have also read that it is made of magnesium, can anybody confirm this?
