Absolute score man! Make sure those kuni's are tuned and synced. Run her hard and hot for only short periods. keep it cool as you can. The PRS and F chassis's are my fav Bomby's. The Bomby twins run the best "right to the bar" for short periods. The triples are more heat sensitive, but that sound is awsome! Clean her up and be proud of yur new sled. Thanks for sharing.
Turn the idle down until it idles around 16-1700rpm. If the idle doesn't change play with the air screws. RAVE valves are super easy. Rotate the wire retainer off, there is a spring inside the plastic cup that will go flying if you don't remove it slowly. 2 Allen heads and the whole assembly comes out. Clean the carbon off, put a new gasket on it and throw it back together. If you hold the plastic on the bellow(it is hex) and unscrew the guillotine to remove it from the housing/bellow.
Rave valves were around by the first Mach 1 I believe. They are easy. Just flip the wire retainer up and pull them out carefully. There’s a spring and a bellows inside. Make sure the bellows isn’t ripped and clean the valve like you would with any other sled
Take those raves out, and at least clean them up, the red dial in the middle, turn them in tight, I've ran those both ways, it will be happier with the airbox, engines last longer too. That was a steal for 200 bucks!
Cool vid my good sir, the 90s triples were a magical time in snomobile history . They are still affordable and great cheap fun! I've been a polaris guy since the 80s and have owned many, before that our family owned many 70s cats and still have a really clean 78 panther like yours in the vid! I would like to Still find a clean 96 ZRT triple cat. Thanks for keeping the 90s triple craze alive! Verry informative and your light added humor add to the commentary perfectly. You have a great collection of the golden years of sleds! Like my dad used to say ! Put down the bottle and get on the throttle. and let's get our knees in breeze! Lol. Miss him alot. Thanks my friend
Lost my dad in 2010. He was a mechanic, nothing he couldn't fix. I bought my first sled off him (el Tigre 5000, 79). We had a couple Prowlers in the early 90s, then a ZR 580. This channel has helped me remember some good times I had with that man. Thanks for the retrieval of memories man. Buy more sleds!
Amazing! When you got the XLT, I thought "wouldn't it be neat if...." and now here it is. Love these old 90s sleds, and what you're doing with the channel. Keep up the great work!
sweeet deal. im loving the triple triple content, brand doesnt matter. They just dont make them like this anymore and the have such a strong powerband and great sound out of factory triple pipes. Next up you gotta find a SRX 700!
Heck yeah Rocky love this reminds me of my early motorcycle riding days picking up what ever cheap bike i could find most of em 80s and 90s and 99% of the time the carbs just need a good going over to get em to run
I'm really enjoying your videos. The three cylinder snowmobiles of this era are awesome. I'm a Polaris fan myself and own many triples, but all manufacturers had amazing triples. Thanks for putting this content out there and keep up the good work. 👍
Thats one cool Formula 3 long track is rare here in upstate NY. Ski doo had power valves on the 583 89 mach 1. Then the mach Z then carried over to all there triples and big twins. Love ur content idea of reliving the 90’s great idea. It would be fun to see todays sleds race these old triples also. big twins against each other and against the triples. If u could find a 95 670 mach 1 with twin piped long track be cool or MXZ 670ho. 700 twin piped wild cat in the ZR chassis or the ZR 700 with single. Both the ZR 700 and doo 670 were iconic kinda ahead of there time. Always thought they were kinda over shadowed by the triples until people caught on the big twin advantage. Ur doing great one of my favorite snowmobile content to watch now very entertaining. Thanks for the awesome content.
Keep bringing back the glory days man. Personally, I've seen that 79 Panther in a couple vids and I'd like to hear that old 500 Kawasaki engine running. Bring me back to my youth (first sled I rode). It looks mint! I've always loved Cats, currently riding a 06 Crossfire 700 twin. Nothing sounds like a Cat!
Pop the covers off the RAVE valves & make sure the are not stuck, you should be able to move them in & out a little easily. If not you will need to pull them out & clean them, they work similar to arctic cats APV valves. Put the covers back on & adjust the red centers with a flat head screw driver so they are flush with the black part of the covers. That sets the tension on the valves. That's kind of a happy medium, if you want a little more low end grunt turn the red centers in. Make sure all three are set the same. Great score Rocky.
I owned one of these. Fast but poor handling and heavy. It was good for it's day but the stuff all the makers were making 7 to 8 years later is a gazillion times better.
only bad thing about those engines are they were known for crankshaft bearings. and pto bearing lube issues. you can drill the cases to address the issue.
Beautiful...congratulations amazing how you're getting these beauties for $200...love all those triples from all brands...yes great content do more vids so happy to see these triple muscle sleds being saved they are so unique and IMO the best looking and sounding sleds ever.
To check if it's running on all three cylinders, lick your finger and touch all three pipes if you aren't sure. My neighbor has a 98 mach 1 700 triple and put a steel crank in it 18 years ago, BRP said you can't do that and it still runs lmao. Better then the junk plastic crank they put in it 😅
Heck ya love this kind of video. Im my neck of the woods people would be trying to get $1000 dollars for that sled, even non running. Even with pretty much no snow this winter ppl want gold for sleds in mn
I had the pleasure to ride the 95 very limited build that a buddy of mine was able to buy new. I was a die hard cat guy I had the 93 700 Wildcat and they were pretty much dead even !
Cool sled great find, my uncle had one of those new when I was a kid, it was a screamer on a trail(although is was definitely not a mountain sled lol) I really want to find one someday
Those are RAVE valves. They change the position and shape of the exhaust ports to make more power. It’s also got reed valves which you can change the timing on and make more power, but that 600 triple will absolutely rip.. tge RAVE valves are why 2 stroke rotax motors make so much power
If I'm not mistaken ski doo were the first to use the power valves on snowmobiles, I have a 1992 MX 470 with the 583 formula plus engine on it , if I'm not mistaken they started using them in the late 80s
I have the same sled, first thing I ever bought brand new, cost me a girlfriend lol, take it for a ride once a year, never had it apart or had a issue with it, over 10000 km on it, will never sell it.
Grab every triple you can I enjoy these videos very very much them formula 3 set uped right just fly you need to look for some formula plus and mach 1 and if you ever see a plus x mach I x grab it there about full out race machines another is the 96 mxzx 440 very very fast for a 440 then there the blizzards
I bought a yamaha 600 triple one month ago and found out the next day that the chain case has a hole in it, one bolt had broken from the drive shaft and eaten it way out the chain case. Luckily I found a spare part and got it to work perfectly now. Just tells you about yamaha quality when the chain has been spinning there without oil for who knows how long time
Now you HAVE to weigh that thing!!! I had a 99 zrt 600, clutched, piped, paddle track. That thing would stare at the sky as long as you could hang on to keep it pinned!! My father had a formula 3 600 and it felt like a TANK compared to my zrt..... genuinely curious as to what the difference is??
I don’t know where people are finding these $200 sleds on RU-vid. That sled would be $1,500 to $2000 in Ontario. People want $1,000 for 1980s Citations here.
As far as power valves go Skidoo actually came out with them in 1989 on a Mach 1 583 twin and put them on everything after that They are a really simple exhaust valve with a mechanical spring and diaphragm (They are a lot more forgiving with oil than the newer valves ) I personally have never seen one stick
