I've been out of the mini world for about 8yrs. the bike was just sitting. I've been wanting to mess with it again. I did KX 60 front forks about 9yrs ago and a sik 110 swing arm. After that, the bike sat. I never did a rear shock. If i remember correctly, I think people were using a honda cr 70 or 80 shock for the rear. Any info for this cheap upgrade?
