My son rides a 2011 KX 85. We recently rebuilt the top end and added a weiseco light weight pistona dn rings and a vortex triple stage reed and the motor is so much faster. But now we are having new problem, no traction in the florida sand and at 93lbs hes trippleing jumps and bottoming out the suspension.
Hes just getting into racing and my questions are:
What gearing should we run on the rear sprocket? (Still running stock)
What Tires are best for florida sand? (Still running stock)
Should we go with Stiffer Springs front and rear now that he apparently wants to jump everything in sight? (Still running stock)
Any recomendations would be great!
