Hi everyone,

Just wanted to introduce myself, as I'm new here, and also show everyone the two vintage sleds that I have.

Both of these were my dads, and I took them after he passed. I have a 1975 Rupp F/A Nitro 440, and a 1978 Yamaha Exciter 440. The Rupp has never run as long as I've been alive. I've ridden the Yamaha a few times, but it's been a long time. My ultimate goal is to get them both running and go up to Michigan, as I've never been on a proper trail ride.

Enjoy the pics!

Welcome ! I too have a Antique pile of fun! It's a 1980 Blizzard 7500+. Mine runs and I took it to a show / fun event this year for the first time. It was a BLAST and i would highly recommend going to one. The other guys welcomed me right into the crowd. Even trying to get me to come to a bunch of other shows they were having a month and two later. Well worth the time and effort.

Thanks for all the positivity everyone! I have a couple questions. First, what's a good way to get rid of that corrosion on the engine parts, as seen on the number plate and such? And second, does anyone have a good resource for parts for older sleds?

Welcome to the site. Those are 2 very nice sleds to have. The Yamaha looks like you could just add gas and go. It’s in nice shape and those were very dependable sleds. The Rupp is a real collector sled. I always loved the looks of them and they are pretty performance oriented. Similar engine setup to the old Merc Snowtwisters. I had a 75 340 Twister and had lots of fun with it. To answer your question on revitalizing the Rupp I’d look on the internet for different ways guys use to clean them up. There are lots of different methods so you might get some ideas that are to your liking. Keep us posted on your progress.

For new aftermarket parts. Dennis kirk & hi performance engineering ( hiperf.com ). Are good sources. As for used oem, there is a big salvage yard here in wisconsin called arts parts. 715-288-6863. They ship also. Good luck.

Get ahold of Bill "Elvis" Stull for help with that Rupp. He is on Facebook or vintagesleds.com
Thanks for the info. I just sent him a message on facebook. For fuel, would I run these on premium? I know the Rupp will need a lead additive, and to be mixed with oil obviously.

Welcome. The guys on this sight have helped me, and many others, new to the sport. I don't think you'll need a lead additive. The Rupp is way cool. I've got 5 sleds from '93-'01; they're addictive!

Back in the day they recommended 20-1 oil ratio and 92 octane premium. But with the oil quality now I know a few guys with the same year hypersleds. They all run 40-1 and just the best premium unleaded they can get. I don’t know any that add lead. I had a 75 Merc 340 twister as I mentioned. Right from the start I ran 40-1 and unleaded premium without any motor or run issues. Not a Rupp but it had a Kholer 340 free air engine.

Not sure if it still in print. But there used to be a vintage snowmobile magazine that had lots of good vendor ads and how to articles. They also had a good website with forsake sections and so forth.

Not true. On a two stroke engine with no valves or valve seats for face contact lubrication having lead in the fuel is a useless waste. It provides nothing for hard face needed contact lubrication. It was originally in fuels for that and to raise octane levels by the use of tetraethyl lead. we have high octane unleaded fuels that can do just fine. If you even look at aviation fuel such as 100 Low Lead, it has practically very little lead as compared to the fuels when that machine came out. Just use unleaded premium.

I don't have any vintage iron (although my 800 triple is pretty close😁) but I'm the first in line to check one out when I see it. Those are two fine looking sleds. I can't wait to see pics of them all shined up.

The Exciter is a 1979, which is a good thing. The suspension was improved and it had a larger gas tank that year. 1980 was the last year for the Exciters. Very light weight and fast sled. Faster across a lake than 1990 400 Indy, but really unstable in comparison with the old leaf spring front end. Have come across a couple of nice used ones over the years that I passed on. Wish I had room to store a couple of vintage sleds. Yamahas were nice back then with oil injection and rubber tracks. Most of the old Polaris and Arctic Cats had cleated tracks that were treacherous on ice.
