Ignore all this if you're the IBA type who approaches riding big distances and "bagging" as many states as possible as a challenge to be met.
I say this over and over in this type of thread, but I think you are being too ambitious on mileage. Any kind of interesting motorcycle route that sees cool things between LA and Cheyenne is going to be about 2800 miles round trip. If you have six days, that's a 465-mile/day average. Unless you hit the interstates long/hard, it's very difficult to maintain a rolling average much higher than 50-mph, so you're looking at averaging 9-hours/day in the saddle. Add a couple hours for gas/meals/breaks, and you're doing an 11-hr day and this is before you stop and do any significant sightseeing or exploring. With no contingency for flats, weather, breakdowns, etc. You're also going to be getting into the time of year where you really only have 12 hours of good daylight and riding through open range country at night is patently dangerous with respect to Bambi. Dusk is an especially bad time. If I'm riding in the fall, I want to be shut down 2-hours before sunset.
Have you ever ridden in Kansas? While I have nothing against the state, it is not a place I'd make any effort to plan a motorcycle ride to.
A good overall daily riding average for a fun trip that sees a few interesting things along the way is 300-miles/day. (I also prefer to plan a day off the bike every four or five days but six should be fine.) I'd reduce this mileage if you're camping as you need to allow time setup/break camp, buy food, etc. I know this may sound absurdly short, but believe me, you'll have a lot more fun working your way to a destination 900 miles distant in 3-days rather than one 1400-miles away. It's a lot easier to add miles to a day than take them away.
