That system would look great on my '77, but I had no idea they were going for what they are. The seller did I good job getting the system ready for sale instead of just throwing dirty old pipes up on the block. Just guessing at a $1,500.00 reserve maybe more. As crazy as the market is for this stuff final price could be a lot more. My pockets aren't that deep unfortunately.
Price seams to be inline. I found an aftermarket set converting pounds to USD these are $1500. I sent an email and got a very quick response. It says out of stock but they are actively looking for buyers so they can place an order.
WOW ! I can't remember what I did with mine when I took them off my 77-Kz-1000, back in the mid 80's. I think that they eventually got thrown out. Who knew ???
I bought my '77KZ in '79. I used to see sets of them hanging from the ceiling in the back of almost every shop. I'm sure $100 would have bought any of them. Most were brand new or very slightly used as a 4 into 1 was the easiest performance upgrade for the bike. As my OEMs were rotting, I consider myself very lucky to have found a pretty good set a few years ago for $250 CDN that cleaned up to a 7.5/10. They do have a small dent, though, that catches my eye occasionally and drives me crazy! (Not $2,000 CDN crazy, though)
