Looking for some feedback 
What would effect the top speed, as far as the sled not reaching its known potential? Example: Hyfax etc... Thanks!

I want to second the choke adjustment. Ran most of the season with mine out of wack and could only get 110 mph on the speedo :x :x And of note the sled ran perfectly just didn't want to turn more than 10k rpms 8) 8) 8)

Silverbullet, what was involved with properly adjusting your choke or did you have the dealer do it? I don't recall seeing anything about a choke adjustment in the RX-1 Service manual so I'm curious in what has to be done. My would run fine as well but would just not get over 10k. I didn't even have studs, purely stock so that's why I like to find out more about this. My first step was going to be checking my carb sync.
