I had an 87 Warrior... my god that thing can take a beating after beating. Was bored to about 380, Supertrap exhaust, K&N air filter, 34PJ carb(jetted), adjustable shocks from a newer warrior, and finally some new plastics... Sold it to my dad for 1,000 after I rode it for four years. Never rebuilt the top end since I bought, so yeah they run damn good.
