What was the article about? Sprockets?
Seems like it'd have to be that, if it's changing rpm at highway speeds.

It's straight forward if your technically inclined, unlike me.
You'll need a new chain and probably will want to swap out the front sprocket also. This will effect your speedos accuracy, which can also be remedied.

I had a shop do it for me and got my sprocket/chain kit from ebay. Actually worked great, I got it for the opposite reason as you, wanted better acceleration. The top speed was effected but that didn't matter much to me.
It lasted damned long, 3 years...especially considering I was too much of a newb to oil it. Ever.

There's always a trade off and if your raising your top speed, i.e. lowering your rpm at 80 mph, you'll lose acceleration throughout the gears.

yeah, you can do it with sprockets... i think its a fairly common mod. the FAQ should have all the info on how to do it.

but personally i think if you really plan on doing a lot of highway riding you should move up. not immediately but once you've got some decent experience.

It averages about 1,000rpm over each 10mph. 40mph-5,000rpm, 50mph-6,000rpm, etc. Even at 80mph, I was reading 9000rpm. That's on a stock '06 250. And boy were my hands vibrating!
