hello guys and girls,
i have been thinking about upgrading the front suspension on my 2000 xr 400. i have read lots about doing the shim stack mod and spring weights.
where do you guys buy your springs???
i have tried ordering from a few companys now, but after each order i get an email or phone call saying they dont make my pring rate!!
now i am no fat pasty but i do wiegh about 85kg, i have been on "race tech" web site for the rider srring weight calculator and they calculated i need 4.6kg/mm spring rate but racetech said 4.4 was the only available rate.
are my calculations wrong or am i really a fat bas****d?
