1997 Skidoo Summit 670 "Lightweight" Mod

[@257Tony]

We still have one of these in our fleet, it was my Moms. 97, 670 w/ 144x2" track, and simmons skis. I still ride it at least once a year, and have a blast on it!

[@800tundra]

So true on the downhill parking. Haha. Could bring a guy to tears. 😫

[@CarlKusterMountainPark]

or.... passing out stage...haha .The old Fuji's in the Polaris had crankcase drains...I burnt my hands as a kid o n the pipes lots bahahahah! Character building moments!

[@CarlKusterMountainPark]

We have it so much easier in todays age (maintenance wise)😁

[@AnDrEw122100]

Those old rotary mills were nice I must say . Bulletproof .

[@HebbsT800]

Those hard mountain bars were killer lol On the chest !!

[@CarlKusterMountainPark]

9 out of 10 doctors recommend them for rib insurance claims LOL

[@slednecksxbox]

More of these videos please.

[@CarlKusterMountainPark]

We are working on it!

[@allenshiva]

Love the skidoo on the sled deck. Can't wait to get mine in!

[@CarlKusterMountainPark]

Perfect for spring exploring!

[@Justgaragenit]

Those big bore rotary valve rotax engine made big power. That 740 must rip. Really cool sled thanks for sharing

[@CarlKusterMountainPark]

They were light, powerful and reliable! I have seen a 800 version from Ralph at Split Second....Heard a rumor the a 900ish one was floating out east ...Crankshop maybe??? Would be cool to see/ ride it in person.

[@Justgaragenit]

@@CarlKusterMountainPark that’s insane an 800 or 900 rotory valve would be wild. You’d need some mega pipes and toilets for carbs to keep up with the fuel. I’d love to see one in person or ride one. Would be epic 🔥

[@OGReeber]

@@CarlKusterMountainPark Crankshop had a magnesium case rotary valve that came out at 990. Saw one of two burn to the ground 20 or so years ago.

[@CarlKusterMountainPark]

They sound good too! there is a 806cc version that is floating around...we have some ideas for the chassis...would be a killer retro build!

[@Justgaragenit]

@@CarlKusterMountainPark that’s awesome hope to see it all together. I have a rotary valve decker 440 we’ like to do a build with in the future. Gotta love the old iron

[@outfitr9703]

Had a 98 670. Rolled chaincase, 141 track, lightweight hood, clutching, it was pretty bad ass in it's day.

[@CarlKusterMountainPark]

It was fun and easy to make improvements on those old sleds!

[@CarlKusterMountainPark]

The 670 made for a great starting point of so many mod sleds!

[@thecabinguy3006]

Awesome video. Thanks for making it.

[@CarlKusterMountainPark]

Glad you liked it!

[@caribooskidoo3997]

Awesome sled. I have a 670 big bore by Ralph also in an old RXL mod sled.

[@CarlKusterMountainPark]

Cool, Ralph is a legend! Is the RXL 1st gen or 2nd gen?

[@OGReeber]

Viton needle and seats fixed the fuel leaking into the crankshaft issue.

[@CarlKusterMountainPark]

hmmm... maybe I'm thinking of monster round slides, if you were pointing down hill... you'd better be fast on the fuel shut off! lol

[@OGReeber]

@@CarlKusterMountainPark ​​⁠No no you have it right. Doo used the “cost effective” needle and seats. The upgrade was from Mikuni thru their distributors like TCI.

[@Lfs1891]

I had the green hood. But dang, that's what I was building. In 2000. 😅.

[@CarlKusterMountainPark]

But.. did it have an eagle on the side! LOL

[@ckfarmz]

U gotta bring it to the Mcbride Bung Bung November 23rd 2024 weekend!

[@CarlKusterMountainPark]

Ohhh we might have a real treat for then!

[@BackcountryAlaska]

hahaha this is awesome! 🤟🤘

[@CarlKusterMountainPark]

Glad you liked it!!

[@70torinogt70]

Nice sled

[@CarlKusterMountainPark]

The colors were great on the snow!

[@DCN_Daron]

Could you go over your drop and roll, I want to put the jackshaft in the tunnel with my s chassis mod but confused with the trailing arm mount needing to be modified.

[@CarlKusterMountainPark]

Daryl Baker at Racer's Edge did the chassis work on this one, He would likely still have the templates in stock!
