Thanks! Yeah the Blizzard is bad ass, it's my number one bucket list sled and I still have a hard time believing I actually have one. The 640 is a 71 yeah. It looks like it did endurance races back in the day judging by the Swedish racing ski loops (they were mandatory) and the twist throttle was a popular mod over here for long distance racing. The pipes are Dougs pipes I think for a 72, one of them just barely touches the hood right at the air vent that 72s don't have. Really should get that dual carb setup on it some day! Take care of that Oly, if it's been sitting for that long and still turns over that sounds like it definitely has potential! Olys in stock form make really nice cruisers I think.

Formulas are nice, I used to have a 90 Formula Plus. It was a real submarine in deep snow but nice on the trails!

@@Hollaendaren yeah I get that submarine deal they were pretty low unlike the Indy of that era and the Yamaha's . I raced motocross though the 80s and had a KitKat at 4yrs old and so many sleds some favs were a silver bullet skidoo a 73 el'tigre 440 FA Yamaha SRX1978 Love you channel

Thank you! :)

Go for it! I went with a Link G4X Monsoon ECU because my friend is running that so I knew where to get help, otherwise may have ended up with MS too. Crankcase injection pretty much eliminates blow back, it's awesome! I have a very short intake tract and I can see some fuel made it out to about where the butterflies are, but very little. Definitely no spraying like a carbed piston port engine! I will do a video on the EFI stuff when I put it back together :)

Sorry I had you worried!

The big question is why do you have sleds in the Florida swamps, watercross?

@@Hollaendaren because I was born and raised in Ontario. My job brought me down here. I still watch every Leaf game. Even the Polaris tripples didnt have the sound of the blizzard. Our first Skidoo was the 10 hp olympique in around 1963. I ran that till I got my TNT 440. My dad kept it and bought a 68 super 370 olympique. Fast when it ran. But was unreliable as hell. Bombardier was slow to incorporate the use of Mikuni carbs and stayed too long with the center mounted engine which hurt them in the end. In 1974 they came out with the front mounted engine chassis. The TNT free air cooled engine was pretty nice. I never owned one but I never heard anything bad. Tiloston carbs were ok as a single carb. 2 were a pain 3 were a nightmare. I actually had a small vacuum guage that I used to tune them. I miss snowmobiling.... but we got airboats down here!!! LOL

Haha, I like your optimism! :) Happy new year!

Thank you for the kind words!

Hade man gjort det här på heltid så kanske man skulle lyckas med det ;)

Maybe later, I'm in a bit of a time crunch atm so I will just put the old piston back with a new top ring.

Thank you! Are you going to Eagle River? My Blizzard 797 has probably raced in Maine back in the day, the team was from St Albans, VT and raced in Canada too so I guess it wouldn't be too far a trip to Maine either.

Thanks for sticking around, sorry if I had you worried! Happy new year to you too!

Thanks! I made the block out of 3 2-cylinder cases. Yeah it's all in the older videos. I have no idea how 4 years passed but I guess I've been occupied with other stuff and not thought about it.

It's definitely a lot more work than you'd think! This video was kind of a worst case scenario for me editing-wise because of all the talking and me not thinking about what I'm going to say until after I press record... But I'm happy to say it was very manageable with the new setup. A few mishaps on the way like my microphone had become unplugged at some point so I had to reshoot some stuff because of that, but other than that it all went a lot faster than before :)

I'm sorry if I had you worried, didn't intend for that of course!

The microphone helps a lot! So much more consistent sound levels. I also just let my camera decide what settings it wants to use, in the old shop I had to use manual settings to avoid flicker. For editing I use a recent version of Davinci Resolve on PC, it has gotten a lot of new features since I last used it. Most important probably the voice separator, my new shop is relatively echo-y but this filter fixes it, and then I use the voice leveler to get the last of the inconsistencies. All this I had to do manually before, every time I moved the volume changed and had to be corrected afterwards in editing. I've spent so many hours on sound! So basically the camera is doing the coloring work, the microphone and filters are doing the sound work. I just need to cut the clips into something that hopefully people are willing to watch and not worry about all the other stuff :)

@@Hollaendaren Im using open source for a while now, although very stable I would like the audio to be automated to remove the pauses and ums and eers (not sure if the free version of Davinci does that) also I must get a better mic. At lease I am doing the same with video let it choose its defaults and have it automatically upload (Sync) to my laptop. What Mic do you use?

​​@@zxspectumsorry for the late reply, my microphone is a Røde Wireless Go. And on top of the camera I have a Videomic Go. I use a stereo to 2x mono splitter cable to record both of them at once, the wireless records to the left channel and the directional one to the right, and I just select the one that's most appropriate in editing. And this way I have a backup if/when I forget to turn on the wireless one :)

Thanks! Yeah the triple sounds awesome :) I will probably have to do a video about it when I put it back together, need to focus on the 277 and 950 first now but hopefully later this winter/spring!

Tack för det 😊

Snowmobiles have a ton of drivetrain losses compared to a bike though! A wheel runs a lot smoother than a bulldozer track ;) From what I gather only about 60% of the crank HP makes it to the ground. But an engine like this in a bike would be cool!
