I'm trying to find out the correct rear shock spring I need for my '87 KX500. I am 6ft 5in and weigh 250lbs w/o gear so add and extra 10lbs for gear. I usually ride sand dunes, desert, and some trails. I used the race tech guide and it suggested a 5.5 (stock is 5.4) but I was thinking it would need to be a little stiffer or is this correct?
