I have a Rotax 277 in a 81 moto ski mirage 1. I’m looking to rebuild. Any how to’s? I can find anything and really need some assistance. I have 90 psi with compression test. Possible I could email you? Thank you! Great videos.

244 👍

I am thinking of buying a 74 Ski doo TNT 440 F/C these videos are awesome , thanks very much for taking the time to post these , cheers from Canada!!

can u show me ur wiring please mine is all messed up and im not getting spark either im new to skidoos

I see the calendar 2013... What is it like to travel unmolested by tsa and still have 2 genders? Must be nice

use a 1x4 or 1x6 board with randomly drilled holes and use finishing nails. this can hold small nuts and bolts. after cleaning i use Krylon or rust-oleum matte clear coat this helps fasteners from rusting.

Hey can ya show us how to set point gap?

Thank you sir

Hi, stumbled onto this super information channel. This is great! Not everyone knows how to time these motors. I knew a light or buzzer was needed and have assembled one now myself. I have what I think is a 71 250 Elan. No VIN plate. The ignition coil is under the flywheel. Your in Canada, do you have a recommended source for parts? Thank you

Do you have any part numbers for the gasket kit on this engine? I have a 68 247 that I want to reseal. Thanks for the videos!

Thanks for the good advice. Where did you get your flywheel tool

Hey I just got one of these from my uncle and I was wondering if you could help me figure somethings out about it. I'd ask my uncle but doesn't know anything about it

Love the sound those old singles make. Question what happened to your Tillotson carb rebuild videos? I have referenced those videos many times.

Very nice

Beauty!

I never knew what the middle reinforcement channels on the side of the tunnel were for, a drivers backrest! Never see this in any other videos or pictures, rare accessory

Never use those de-glazing hones on a 2 stroke, lol .. they are junk. If you want new rings to seal 100% true up the bore with a line hone, which will remove just enough material to get new rings to seal completely. Also test fit those rings with a back light .. any light comes through, the rings are junk or the wrong size (which happens frequently with new rings). There is really no sense in rebuilding a motor like this without getting the ring fit perfect.

Is timing only for older elan engines?

What are the torgue specs for the head nuts?

Obviously alcohol involved....who else would put that much effort into restoring something just to beat the crap out of it?!

It will eventually shake itself and everything around it to death. That muffler never stood a chance.

Thank you this video helped me time my 1971 rotax 335, back to the trails

Very great content, good video! I love these great engine maintenance videos! I used to sit back and watch my uncle work on his machines and his preventative maintenance, one was his Alpine 440. I loved looking through his maintenance manuals!

Great work! I learn new techniques shown here, very professional work! I get annoyed by the circlips! I love these types of vids! Dude got great art work!

Great video that is one of the Rotax Engines I keep my eye out for. That is great wrench skills you got my respect!👍👍👍 I started out with my tundra 250 handme down with seized Engine for free. I love my daily driver 92 JagDlx440LT that I rebuilt. I changed tygon fuel lines throughout, cleaned out the debris, and replaced the fuel pump. My cousin did the clutch work, and lowered the gearing. I go logging alot towing a sled with my Machines. It's my 1st Cat and it got my respect!

for all you young guys ,, i remember in 1962 there was my next door friend his dad would take us out on his front driven belt with a large rear hinge seat with 2 wide skis ,we would sit behind on the seat all 3 of us,, and with 4 ft of snow ,,only i say only us could plow going us a hill for miles ,, while regular snow mobil COULD NOT,,

Yep...may years of doin it in dealerships in the 60's- 70's. Nobody has a clue about points adjustment or timing these days!

Very nice! ...I did that for a living for 42 yrs .! I need a retirement project now!

Finally!...a snowmobile repair done by someone as thorough and finicky as myself!

I had that engine in my first sled...a 1967 Olympic. First failure was the intake side of the piston broke off taking a chuck of cylinder sleave with it . Second failure the cylinder cracked all the way around above the holdown nuts. I had to hold the cylinder down with one hand to limp it the last 2 mi. home! ...I replaced it with a highly modified 293 Sachs engine...and never had another issue! That was long ago...havn't had an issue with a Rotax since!

Incredible. We had one of these 50 years ago. It was $800 brand new.

Any issues with the paint?

thank you nice///

Got myself a

That looks awesome

Music to my ears👍

Where can I get that exact kit I can't find the nuts that thread on to the flywheel bolts and the polar bolts

Do you live in nb?

Do you know where to find a cable for the decompressor?

I didn’t see you replace the rings.

Who plays the music?

How did you do the elan in the back? Could you explain the process a bit

What’s the background music? It’s awesome!

The Snojet guy has it figured out, go slow enough and the bumps won't bother ya.

Excellent Video Series. With this 250 Type 247 engine being made from 1963 to I think 2006 and rated at only 12hp@5500rpm, a Performance upgrade video would be nice. Considering the 246 Blizzard Single was rated 29hp@????rpm.

I admire your work GaWajn. Did the 247 ever come stock with this roller clutch? Also, how did you polish it up like this?

I had the exact same sled year make & model! Had a 292 Hirth in it & "SnoJet" embossed on the track that left an imprint in the snow wherever you went. A kind of "Sno Jet dude was here" thing. LOL One of the best machines I ever owned, right up there with my old '68 Olympic with a 335 rotax. I wish I still had both of them.

Some parts are detailed, other parts completely missing such as clutch alignment. I'd rather listen to directions than a banjo.

Why my 1977 Rotax 440 base still leaking???. I cleaned it , use Permatex Motorseal leaks again after 2 hour of use ,Torque to 16.I am clueless need help...

If only the flywheel came off that easy.
