doodie,all is good.may be sly fox is better.over the winter i am going to do some experimenting with the exhaust port on the kx5.i
have a 83 and 84 cylinder and will map both to compare,then make some changes to the water cool one.

KXcam22:
Doordie,
  That pic is a cool shot. Easy to see the how the filler flows with the reeds in. Nice case reed motor (yamaha?). How was Gotland? Cam.

hughes:
What shops are there that can balance our cranks :?: Motor will be torn down this winter.

Brett:
Balance crank? i think you mean align after getting big end changed.  Cranks are only balanced perfectly for one speed only so maybe people change the balance for a different speed but i am sure wouldn't matter a stuff when riding a 500.

gowen:
I had Eric Gorr balance my crank for 7k-8k area. Nothing, but down low. It is horrible! Numb my hands within' seconds. But when I'm doing a WFO run, it's as smooth as silk.
