2011 600 rmk 155 clutching/gearing help

[red99powerstroke]

I have a 2011 600 rmk 155 CFI 4 that will have a SLP pipe/can set

Thinking of gearing it down and getting it clutched for 9000-12000 ft.

Would it be good to go 19-45 gearing or will it fit? If so what chain would I need?

What weights would work good for that elevation and gearing?

Last but not least would it be worth buying a high elevation head for a 600?

Nobody has any input?

High Elevation setup

I have mine set-up for 8000-10000 feet i run this.

Blue/Pink primary spring
Red / Black driven with delrin washers.
I changed my gearing to a 22:40 chain still 76
Stock helix
10/54 gram weights. I tried 56grm did good too.
I did mill my head .020 to up compression now 125psi at my house which is 4780' at 10200' i was 117.
All this with a single slp pipe and can setup.
This setup on my 11 600 HO pulls 8220-8255 all day

Well I have been out west with it twice and I was pretty happy

This is all I did

19-46 gearing/10-56 weights and would run right at 8100 RPM at 9,000-11,000 ft.

I had a bog and figured out when I would turn my hand and thumb warmers on my volt gauge would drop 2-3 bars turn them off and it would go back up so I changed the voltage regulator and now at idle it doesn't matter what is on or off the volt bars don't change so I hope it was a voltage problem for my bog
