Unfortunately it didn't pass  :-(

Yep... It's a bit haggard but a little welding, sanding, filling, more sanding, primer, paint, decals, bearings, and seals, will have it looking great again.

I made a bit more progress today.
Machined the slots out to 25mm and assembled with a complete KX450F rear wheel, axle, spacers, ect..



Now I need to make the hanger for the brake mount..

Nope... I hooked it all up and it was not better then stock.
To make it better I would need a better master cylinder and it was heavier then the KX500 setup which is heavier then the KX450F setup.
So, I am using a 06-15 KX450F rear brake.
Sean already has a newer master cylinder on his bike so that should be ok.
And ask Oscar or Mojave... Sean is hard on a rear brake..

That stator coil looks far bigger {more wire ] than a stock stator ,maybe thats the reason the reading is high?
i got a reading of 290 from a larger stator coil before

I've had more then a few that were in spec but then again I've probably had 30 or more at one time or another.
More often then not they are out of spec  :|

The one thing that surprised me was new factory parts, gears, shift forks, shift drum ect that were not in New spec...
Sure, they were still under the service limit but come on... New parts not in new spec???

I know you ran into that a time or two motorrad...

I took Sean to LACR this past Saturday for a test.  He brought his KX500, Mohave Greg brought his KX500 (Sandblaster built) and I brought my KX500 (Motorrad built) and CR500AF.  Sean was able to test the 4 bikes back to back and give very valuable feedback on the characteristics of each one.  We now have a VERY good idea of the motor that will be built for Sean.......Regarding the rear brake........Sean came in after 4 laps on Greg's bike with the rear tire locked up.  We feared that the tranny had failed and locked up.  What had actually happened was Sean heated the brake fluid so much that it built up tremendous pressure which locked up the rear brake.  I took a wrench to the bleeder and when I took the rubber boot off it literally POP'ed off.......When I cracked the bleeder the rear caliper made a loud POP sound and the rear brake released.  I know for a fact that Sean has cooked the rear brakes on the KX500 to the point that the pads would be bent in a "U" shape.......This is something that used to happed to the Ty Davis.  We should have better luck with the KX450 rear system on the bike.  Sean has told me that he uses the rear brake on the KX500 during a moto that it will completely fade by the 4th lap.......so he has learned to handicap himself by riding a complete race without a rear brake.  Once we fit him with a better rear brake that he can use, his lap times and track performance should increase.
