I have ran 15-47, modified the inside radius on the front chain guide plate but it pulls the motor down pretty good in sand and you will find yourself stretching 4th to pull 5th hard with the 93+ trans.
I prefer 14-47, its still good for ~97 mph, and will rip instantly without bogging down

Personally, I think you will need as much air as you can get, at high altitude with less oxygen. Guys run retarded high compression too to compensate. Use a air foil in the carb maybe if your not satisfied with part throttle transition. Of course gearing, and other internal engine mods all play a gr...

yes ~8300 rpm stock set up lean, and 8700 on one of the motors I set up for RPM... that was a stretch too Get a pipe for that bike, how can one even compare with a crushed pipe. when the snow melts I break in both bikes I have. One is Adams TWIRP, the other has very mild exhaust and head work, both ...

The engine is NOT loaded when the tire is spinning 80 mph and the bike is not moving.... thats free revving basically Loading the motor as in like a dyno when testing what it will pull in a tall gear. Loaded as in when you are a gear taller than you should be, with too much traction to pull the gear...

oh, and 9270 RPM is impressive, considering I have not seen more than 8700 on any CR500 motor I owned, even with the exhuast port raised 3mm.
Chris.... yours its trail and torque ported right?

Unless running professional studded tires, on bare clean swept ice like in an ice race, the change in power will never be felt on ice and snow.

Its not like he had it in the dunes ansd could load the motor.

Clyde have you ever driven your car in snow or ice?

KX 500 has superior engine design in every way and inferior manufacturing / casting. The clutch cover is a failure as well do to the fact the waterpump must be removed to access the clutch and the whole side cover must be replaced if the brake pedal pokes a hole in it.... and they always do eventual...

Yes, I do like a S-12 as well. Michelins are known for being very light tires. A better handling tire with better profile for cornering. Not as durable nor as heavy as M5B, but a very good tire. If you ride deep sloppy mud, the M5B gets the edge in traction IMO. Its hard to argue with those monster ...

the IRC M5B 140 is really big, tall too. I think terraflex might be the only ones bigger. I would prefer a 130 over the 140. In all honesty, its not a motocross handling tire, but a great play tire with really good wear characteristics. It will lose the edge in a few hours, but never chunks, never n...

I dont want to criticise cause I know its a bit of work and time, and you have a done a good job, with nice pictures.
stock compression, dome, stock port timing basically, 70 HP at the crank maybe...

Beautiful pictures, and super super clean work.

have you checked piston to cylinder clearance? ring gap, and was it over heated? Looks like the rings are deflecting / chattering off the top of the exhaust port, I would check chamfer, ring gap and piston clearance. I would make sure it had coolant, and ensure it was circulating. I am no pro but I ...
