nutter my dad was a polaris dealer from 72 to 74 in newburgh ny 1 was 8 in 74 we had a 74 colt 250 twin with a 72 335 top end and carbs it was a fast sled for us at the time we also had a 250 single colt and rode the piss out of that thing. we would call our dad every day at lunch and ask him to bring 5 gallons of gas when he came home . the best memmories thank you for keeping them alive with all your builds etc
Great story. Glad you are enjoying the Colts!
just passing by NutterVille on 35. They had some snow up in Virginia Mn
Glad to see the channel growing, well deserved!!!
Thanks!
I really appreciate those kind of videos, keep'em coming!
Thanks, will do!
Great info!
Thanks!
Always an informative video on your channel, enjoy every bit of it including watching the puppies play in the background ! Boy I'd like to be the fly on the wall when you are working on a big project ! And be nice to ask the Polaris crew there some Polaris sled relevant questions in person ! Thanks for the excellent videos ! Clean the carbs !😅😅😅
Thanks 👍
🔥right on man.. really enjoy all the tech talk and sled builds 🔥👊🔥🏍⚠️⚙️🔨
Glad you like them!
My Dad was also a Polaris dealer, my first sled was a 250 colt!
Awesome!
This things gonna be awesome when shes done! Its gonna make me wanna build one in a colt chassis!🤘
They are fun and in the words of Frieburger "It's more fun to go fast in a slow car than it is to go slow in a fast car."
You got that right!
Good luck John. Hope you do well.
Thanks!
Good info Nutter! It’s always important to build a sled for the class you want to run in 👍. I’ve heard many people get all these great ideas to hop something up, forgetting it will bump them up in classes, so really no point to it lol
Cheers 🍻
Very true!
One gotcha for anybody thinking about putting a "indy trail" cylinder on there is that the rod on the colt uses thrust washers on the wrist pin and the trail uses them down on the big end. I have not tried to put an indy trail piston on a colt rod but I'm guessing it would be a relatively easy milling operation to modify the piston to accept the the thrust washers on the wrist pin. I may have done that with an ATV piston which has identical dimensions to a colt but a larger bore (oversized pistons are legal).
Good comment Andy. I've done that machine work and I forgot to mention it in the video. It's pretty easy if you have a mill.
Another nice thing about the little 244 that probably isn't appreciated is how beefy the bottom end is. Doubled up 6206's on the pto side and a steel rod, the bottom end on the 244 is beefier than my 290ss, arguably more stout than a 340ss or a 194R.
I know the Sachs single cyls has aluminum rods and bushings instead of needle bearings, but they still seem to hold up well. I've never been inside the 194R.
do you have a show that you rebuild a master cylinder on a vintage polaris around 1997 xc 700?
Yes, I have done a couple rebuilds. I think the Walnuts series had one somewhere.
How much compreasion shoukd i have on a 76 340 ss polaris colt ro run mine only has 90 lbs on both cylibders and flooss out right away thanks
should have 120 psi. Time for a rebuild.
northbound with more road salt. Didn't get much snow here either. How depressing
We're getting snow holed. Snow everywhere else but here and NW Wi.
@@nuttersspeedshop we have a dusting down here in Good ol Henderson Mn
So I'm contemplating the cost and how to complete my project. If I buy beer in bulk, leave a trail of them every 15 feet or so from you house to mine, what would be the cost? At my house would be my Polaris touring 2up sitting outside under a big tree branch, neglected, and needing tons of maintenance (just the carbs cleaned). Pay no attention to the "Cage like" object hanging from the branch...
Or Sastquach lurking in the bushes
A trail of hundred dollar bills would work a lot better than a trail of beers LOL. Good Wile E Coyote trap though LOL.
Does the 250 from the Star make any more power?
I don't think so. I have a star cylinder somewhere but couldn't find it for the video. My recollection is that it is much more like the Colt cylinder than the Indy trail. A quick look in the Polaris parts list illustrations confirms this.
Hope u guys are getting blasted with fresh snow like North East
We're not. A lot of Mn and Wi is getting what I call "snow holed" where the storms go everywhere else but where we are.
