  1. 8000'-12,000'+ same day near Sargents, CO
  2. Anyone know if the trails they are riding out of KC are open to the public? I used to live in Victor and accessed a lot of the Big Hole and Snake River Range trails from the east side, but never as far as KC. A buddy raced the Cow Tag last year and said the course was awesome. I'll be back up next week and would like to explore a little bit
  3. Last weekend I got some great gas mileage on the 17' 300rr. I had just rejetted for riding at high altitude, 7500-10500' on the Beta chart. Actual riding was from 8k-12k+ with some long climbs. I started off w/ a full tank of ethanol free gas 91 oct. (first time trying the pure gas/second tank) and dumped in a quart of same gas when we stopped for lunch. When we got back to camp there was 40 miles on our odometers. I went to the pump and added .85 gallons to top off the tank. So .85g plus .25g = 1.1g and 40mi/1.1g=36mpg? My best mpg to date was 28, at lower altitude, richer jetting and corn gas. Was it the leaner jetting or pure gas , or the combo, responsible for the increase?
  4. I'm going to re-jet my Beta 300 for some high altitude riding next weekend. 8000'-12,000'. I'll be following the Beta jetting chart (7500'-10000') which is said to be pretty spot on. I want to try some ethanol free gas, but was wondering if that will affect the jetting and make it a little richer than what the chart is wanting. It's always ran great on 91 pump gas, just wanted to see if there's a noticeable difference in power and MPG. "Also, ethanol messes up your air/fuel mixture since the stoichiometric air fuel ratio for ethanol is 9:1 vs 14:7 for gasoline. So basically, adding ethanol leans out your fuel mixture, and generally a lean mixture means less power and rougher running. Most modern cars can compensate for this, but your 2 stroke KTM with a carb has no way to adjust for this." http://bkeracing.com/the-evil-ethanol
  5. My 17 300RR had a couple of issues that were known by and fixed by my my dealer. The thermostat leaked and the the stock head o-rings were bad.
  6. delete, wrong thread
  7. http://bkeracing.com/ahis I bought this when my TE order got shut down (see post above). I've been very happy with the results
  8. Anyone tried this gizmo? http://www.airflaps.com/

    I wonder if they'd let them swap in batteries at a pit ?
  11. ALTA motors dirt bikes enroute to Erzberg stollen from rest stop in England. The victim is a good bloke that provides a lot of stoke for life on a bike.
  12. I got this last fall and love it. Ventilation is great, probably on par with HDR's "custom" lid. Light too https://www.leatt.com/shop/moto/helmets/helmet-gpx-5-5-solid-white.html
  13. Yeah, just seemed weird and that it may affect performance
  14. I repacked the pipe on the 300 and went riding for 2 days. Pipe didn't drool out of the pipe but seems to be seeping at the seam at the tail cone of the pipe. I did not remove the rivets back there. I'm 99% sure the stinger lined up w/ the SA when I put it back together. Do I need to pop those rivets out and seal up the tail cone?
