Rear wheel HP....how much??
« Reply #15 on: October 24, 2005, 09:06:00 AM »
Never dyno'd my KX 500 , wouldn't mind doing it though.  If it is done at the rear wheel, do you have to take off the knobby and install a street tire to have smooth contact with the roller?  My bike makes much more power on cool damp days than on hot dry days. Is humidity and temperature compensated for?
 How is the engine dyno'd at the crank? is there an adapter that bolts to the flywheel?  What does it cost to have the dyno hooked up and charts printed?
  When my CR250 seemed slow I wanted to buy a CR500 but found out they stopped making them back in 2001.  So after a small amount of research , I found out that I could buy a Brand new KX500 ( last fall ). I am so impressed with this bike, it handles great and has enough power to satisfy my need for speed.  I  am convinced that whatever color 500cc dirt bike you happen to own it has to feel fast.
  Good luck with your ice racing, keep us posted on your results. I would be interesting to measure the first second and third place ice race motors on the same dyno to see if the power results are the same as finishing position.

I still reckon that "torque" is the biggie here. Horsepower is nothing without Torque. Necksnapping, wristwrenching, fingerstretching, TORQUE!

My riding bud hates riding behind me. When we ride we race each other. He might be alittle faster than me in the woods but I can hold him off with roost in the rocky areas.  :lol:  :lol: He's riding a yz250 which is very fast in the woods. He never complained about looseing any teeth :cry:  :cry:

Flattracker60,

You can look at Mun and mine gallery for tuned KX500 dynoed in different dynos,but still very close to "truth". :wink:
I think a well built kx500 reach about 55-58 rwhp stock.
You can pickup 5hp "very easy" with aftermarket parts and a dremel,after that?s much more job. :twisted:
It`s vary much if the dynos is calibrated different ,up to 10%. :?

Very hepful, thanks Doordie(and the other guys). My KX is stock other than the pipe and Boysen Rad valve. I can't help but think I will have some 'tinkering' done to it. I look forward to running it on the ice. The  A.M.A. Amature National Ice Races are being held in my back yard(Wisconsin). I hope to have the bike figured out soon. I know it rips.

Other than the type of stud(Kold Kutter ice racing screws), there are no regulations. My tire builder uses around 1100 screws in the rear(Kenda ice racing tire) and 800 in the front(Dunlop K495 I think). I use a 'lefty only' stud pattern. I have a pic of a tire I can email to someone if someone wants to post it for me.

Flattracker, here are your pictures. I had to run a resize program on them. Email your tire pictures and I will post for you.
