I have a 88 Blaster that will need a new top end soon. I have been throwing around the idea of trying to sell it or trade it, since I also have a Warrior. A guy offered me a straight up trade for a quad. It is a 92 ltr 250 frame modified to fit a 87 Quadzilla engine. He says the thing runs and everything it just needs jetted. The reason I am asking is because i've heard about how many engine problems quadzillas can have. I'm just wondering what you guys think? Thanks a ton in advance!!
