Geeze, years ago, one of my first sleds was a 77 exciter 440 AC.
I swear to you, even now I think it was the best sled I eva had? OK the suspension wasn't the greatest but, that sled would move

the fastest I went with her on the lake was just short 160 kms ~ 99 miles/hour. Back then that was fast.
This was the one sled I had that I never had to fix, except for the the main shock on the suspension, I was changing that sucker every season?
I bought it from a local TV studio that had bought it for a commercial in 1978, it was used for three days on the commercial than parked in the studio garage until around 1989/90 when I bought it. They told me for the price I was paying I wasn't aloud to start it, the sale was "as is" "as seen" "as touched".
Anyways I paid something like $600 Canadian ~ $400 US. It was the best $600 I ever spent.
