After more than 6 months of lots of riding, I consider it a must for most KX500 riders.  Add the other basic changes noted else where on this site, and you have bike that is a true joy to ride.....

Just so I'm clear on this what size flywheel weight do you recommend.  Secondly, does the flywheel weight have an ill effect on the crank bearing or seals?  I question the life expectancy of mine.  Should the crank be trued or balanced (not sure of the correct terminology) before adding the weight.  Thanks.  Excellent post.

ShanMan:
The only weight available for the KX5 is a Steahly 14 oz. unit. it does not have any ill effects on the bearing/seals, primarily because the unit is balanced and as such creates no additional load on said bearings. You do not have to have the crank assy balanced, but if you do, your 500 will have less vibes than most stock 250's! Hope this helps.  :mrgreen:

mikesmith:
Im not sure but the 10oz was for an older mid 80's k5,14oz is what Steahly sells but Im sure I read in there catalog for a price they'll make it lighter or a custom heavier one.

Rick:
Don't opt to have the flywheel  lightened.  I run a 14/45 in the trees for tight technical riding, and with the flywheel, have no problems with the bike dying.  

You will not regret the addition...
