My wife took her Savage to the Faith Riders Friday bike night here in Florida tonight.  They had one of those portable dynos there and she won a raffle for a free run.  So, she lined up the little Savage amidst four or five crotch rockets to hit the rollers.

Let me just say that I hope I never hear that sound coming up behind me when we're riding!  

Anyway, I don't know if anyone here has ever bothered to put an LS650 on the dyno - I know we never would have paid money to do it - but I thought I would post the graph.  I had no idea these bikes would run close to 100 MPH - that is just scary.

This bike is mostly stock, but I did put a HD sportster muffler on and I took out the white spacer and put two small washers in its place.  They guy who was running the dyno said it was running a little rich (which is what I wanted) and that he thought it would crank out a couple more HP (and hit the century mark) if I leaned it out a bit.

Of course, I see no real need to do this, and the speed numbers are meaningless anyway (since there was no wind resistance) but horsepower was about what I would have expected (just shy of 30 at the rear wheel) and the power band seems (to me, at least) to be really flat, which confirms the seat-of-the-pants feel when riding it.  I was really pretty suprised at how the little one-lunger compared to some of the other cruisers there.  Of course, the V-twins all out gunned it but not by as much as I expected -  

Here's a link to the graph - I can't figure out how to add the image to the post directly.

You are welcome!  I couldn't wait to get home to post it.  It was really very funny to me because these sport bikes were posting stupid numbers (in the 110+ HP range) and then there's this little thumper up there raging it's guts out.  It never back-fired, smoked or hiccuped, though.  It just screamed!

There were a couple other criusers there - a small Vulcan (I didn't get the displacement) and one guy with a Harley in the 1400cc range.  The sport bikes were the stars of the show but I was most interested in how the Savage compared to the larger cruisers.  The Harley hit just above 52 HP and the Vulcan peaked at 44 HP.  I was bummed that I didn't have my bike with me (I arrived at the event in my truck) because I would have loved to see what it would do (it is a slightly modified Marauder VZ800).  The Faith Riders are a truly great group of people who try to accomodate riders of all ages and styles.  Most of them lean toward the cruisers and tourers but they have a number of members who are sport bikers, too.  I think they hired the dyno guy to appeal to the sport bike people and they had a nice crowd.  After the program was over, they opened the dyno again for ANYONE who wanted to give it a try.  I thought that was nice.

Your max hp was at about 75 mph on the dyno. I wonder where that would relate to on the highway? For instance, top speed on mine is about 85 and that was with a tail wind! That was on a stock 2002 with about 15,000 miles on the odometer, 225 lb rider, stock Suzi windshield, and 5000ft elevation.

My most comfortable highway speed is about 60 to 65.

Ken, at 5000 feet you'd be lucky to get 24 to 25 hp because you loose about 4% per 1000 feet. On a hot day you'd have even less so 85 was pretty good

The stock bike in proper tune might be 33.7 HP at the crankshaft.....but I suspect the DYNO run was made at the rear wheel on a chassis dyno (there is a loss of power through the primary drive, transmission, belt drive, rear wheel bearings and tire contact).  And most bikes with the factory jetting are not running at their best....and a proper re-jetting of the carb for the elevation and humidity when the DYNO run is made - will likely to allow the engine to make more HP.
