The guy from work I sold it to said it has been running great for him. That sled was trouble free for us, gas and oil, all we did to it.I agree. I have a friend that starts his 79 El Tigre a couple of times a summer just to fill his garage with Klotz.
Back in 2000 I snow checked a brand new 500 version of this 45th Anniversary model. Wickedly fast 500. Had it for several years and eventually sold it to Elf. He used it as a family sled for many years and finally sold it to another fellow. As far as I know, it’s still going strong.
