yz426frider

ok, so im new to this thing so lets see if it works. i recently bought a 2001 YZ426f and the suspension on it is wayyyyyy to light for me. i think it is set up for a rider that is only like 190lbs but i weigh 210 so i need help with fiinding a web site or just getting brand names of rear springs and front springs. thanxs, 426rider
