In an earlier thread http://www.venturerider.org/forum/showthread.php?t=60093 I expressed concern over power loss and low fuel economy at altitude. (See the trip report on page 2) So today I had my RSV run on a dyno to see if some electrical or mechanical problem might be the culprit. The first chart is 'one run' in fourth gear and 'one run' in fifth. The Second chart is 'two runs' in fourth and 'two runs' in fifth. We ran in fifth because that is where I experienced the most problems on my trip. The bike was flawless on the dyno. The rev limiter on my bike clearly cuts off at different RPM depending on which gear it is in. Fifth at about 5600 and fourth at about 6600 rpm. My guess is this is probably because of the speed rating on the stock tires. Both techs at the dealer reported I could expect about a three percent loss of power for each thousand feet in altitude. Since a lot of my riding on the trip was at 5,6, or 7,000 feet that seems consistent with my experience. Horsepower is on the ground and after gear reductions and drive train loss. So it is less than the engine horsepower in the specs.

my wife wanted to take a ride to Roanoke Va. today, about 130 miles each direction. i decided that since the max speed limit anywhere i drove today would be 65 mph max, that i would make the entire trip in fourth gear. 98% of my riding is two up and my gas mileage lately has been around 33mpg but that was using fifth gear. my max speed today was 70 mph indicated on the speedo and if mine is 7% off then i was actually doing around 65 mph. the terrain from where i live to Roanoke is mildly hilly, so driving @ 65 in fourth kept the rpms in basically the sweet spot and especially pulling the hills. on my refill on the way back home the odo was showing 180 miles and it took 4.3 gals. to top it off - so essentially i got 42 mpg, which is 9 mpg better than i was previously getting. i would like to open up this strategy for discussion, such as pros/cons of fourth gear engine rpms vs. fifth gear engine rpms on longer trips. can anyone with a tach on the rsv or rstd tell me the rpms @ 70 mph indicated in fourth gear vs. rpms @ 70 mph indicated in fifth gear. i understand that fourth gear is technically an overdrive gear but am interested in your opinions. looking forward to the discussion, thanks ! buz
