I'm not really sure on the 88, I didn't buy one new.

Remember when your looking to by a new toy. You research it, shop it, go to the dealer 5 times, kick the tires (for real  ).
Thats what I was doing when the 500 just came out. I went from a new 85 Zuki 250, to a new 86 honda 250r. Now looking to go back to Suzuki that I really didn't need. So to help kick myself over the edge, I found a deal and bought a pipe for a LT500. But I didn't own a LT500, so only one fix for that. Off to the dealer I went. The pipe went on the day it came home. So I have a new factory 87 pipe and silencer in the attic that was never run outside the factory / dealer
