When my son hits 11 or 12 he should weigh in at about 90 pounds - I can;t imagine what he will be like on my 350 or less sled - 540 ported, tuned, dual carbs - should be pretty funny.
A Float rear skid with no idlers is LIGHT, I can't believe it every time I lift mine when it is out of the sled. And it is a 162.
King Cat ti springs take a bunch off, as well as front Floats.
