Yeah Ive spent a little time on it, and its very very comfortable. It is pretty heavy though, ive gotten it stuck once all ready and its got some weight to it! The reverse I can do without on my own sled, I never need to back up, but yeah very very nice option.

Im actually looking at buying a summit 670 tomorrow as well, always wanted one and came across a later 90's model for pretty cheap.

I always wondered why guys put risers on sleds out here, do you find you stand up alot while riding?

 

I like to stand riding as much as I can. Other than gaining a little more control (I feel), I also have either a herniated or compressed disc in my lower back. If I ride sitting down on rough terrain for very long, I'm in misery for a couple of days after. I'd much rather have my legs take the shock as much as possible.

 

Ok so im going back a little here on the reverse thing. I used my womans Grand touring yesterday to skid some firewood out of the bush, and the reverse was so handy, my next sled is gonna have it for sure.

I was checking out a 670 summit, but had a pretty bad leak through the weep hole, so I dont think im gonna get it, now especially since im in love with reverse! Just gotta find a way to make that rear hitch a little more rock solid on the grand touring now so i dont bend it, from abuse haha.

So my ideal sled is now a late 90's summit, with reverse

Interesting about the control. I find the exact opposite, except when playing around hitting jumps and whatnot. But Ive also acquired a certain style of riding over the past 25ish years, so Im definately used to not standing up.

Sucks about your lower back too man. Sledding is about the worst activity to do if you have back problems as well, but how can one not sled?!

 

Like I said, reverse can be compared to 4x4. Once you experience it, you'll never go back Sounds like you need more of a vk540 workhorse

You should be able to find a late 90's with mid kms for less than 3g. Reverse can be added I think, but its much less hassel to find one with it!!

 

Yeah a work sled would be great, but I also like to just sled around as well, where a work sled wouldnt be as fun! If only I could justify having a work and a play sled!

Yeah those summits are around, it seems like I just cant find the right one though. Ive thought about adding reverse, and if I cant find one till the spring i may do that, but I have enough unfinished products haha.

How did the service on the rmk go? Ya ever get the phazer fixed?

Do they include servicing on your new sled? Most guys service their sleds themselves, so i was just curious.

 

Service on the RMK cost me 140.00, I could have did it, but it would have taken me more time, more frustrations, and I made more in the day by leaving it with them than I would have saved by doing it myself. It consists of adjusting the track, ski alignment(if needed), chaincase oil change and adjust chain(if needed), general inspection and lube/bolt check of chassis. Like I said, for what they charged me, well worth leaving it to peeps who know the sled.

The phazer is an interesting issue. After our 330km ride on monday, the reverse worked fine. I couldn't get it to duplicate the problem. I did take it to the shop and the service manager who is also a very competent mecanically inclined took it for a ride and checked it over and couldn't get it to fail. My FIL had an interesting comment that perhaps they washed it before I picked it up (which they had) and water had gotten into some connections and was playing havic until it dried out. He's a small equipment mechanic @ JD and has seen this many times. Its common knowledge that water and electricity is a poor mix...

We're heading out around 10 for the day, we'll see if it gives any grief through the day. Other than that little glitch, the sled is actually a hoot. I need to get wider ski's for it, and I'm looking into converting it to the 144" mountain tunnel and track. If it were 80-100lbs lighter, I'd consider getting one for myself. It doesn't have near the power/weight ratio that my RMK has, even with a turbo I don't know if it would, but it would definately be close. However, then you've sacrificed another 5-6g and prhaps some reliability??

 

Ah yeah, makes sense about why ya take it in. I personally like to learn my sleds and lolearn how to tweak and maintain them, but its not for everyone! There is ALOT of tricks of the trades and tweaks that take alot of reading and learning to figure out. In the end I always find it worth it, as I can tweak my sled (or bike or whatever) to exactly how I want it, and since I buy used, I have the knowledge to fix or repair on the trail as needed! (Long story short I guess Im just a do it yourselfer!) Throughout a winter of riding, a guy could pay someone 1000 bucks to service a sled, and since I only paid a few grand for our sleds.. well you see where Im going haha.

Yes electrical components can do funny things when washed. The bad part about that, IF thats the problem, is snow. Snow can find its way in funny places in a machine, and if it got in there and melted.. then the problem is still there. In the summer or spring time, what i would do if i were you, is check some of those plugs to see see if its loose or whatever, might need to reseal it.

As for adding turbos to a four stroke sled, I dont know if that decreases reliability or not. I really know little about the four stroke sleds. When its time to upgrade in a few years Ill end up looking into them more though, just due to the supposed better fuel economy!

 

With warranty on my sled, I'd much rather have someone else do the maintenance then me "trying to figure it out" and wrecking something and be SOL with warranty.

If you're considering a 4-stroke sled, don't kid yourself on the "fuel economy" issue. Mine and the phazer rode on exact conditions, exact mileage riders of compareable size give or take 30lbs, were only 6-7 liters difference at the pump. If the 4-strokes could be comparable in power to weight ratio, I think there might be a larger discrepency. I'd really have to ride with the dollar for dollar, lb for lb, the new two strokes have come a long way on the efficiency side of things, as well as being very clean running. Oil injection is very refined as well as the oils themselves being very advanced past the days of every sled being a mosquito fogger.

It'll be a while before I'm ready to take the 4-stroke plunge. The phazer only appeared because it was a chance to pawn off one of my street bikes to have a 2nd sled. I didn't really need 2 bikes. I would have preferred to buy a 600 shift or 600 switchback, and I probably will do just that next season.

I was checking out a 670 summit, but had a pretty bad leak through the weep hole, so I dont think im gonna get it, now especially since im in love with reverse! Just gotta find a way to make that rear hitch a little more rock solid on the grand touring now so i dont bend it, from abuse haha.

Sheldon, what is a weep hole? I worked for a skidoo dealer in the late 90's as a mechanic and never heard of that. Do you mean the Rave valves? If there is leaking from there that is an easy fix. Just curious.
Adding reverse to a summit is fairly straight forward. I would keep an eye out for a 98 or newer summit X, those things received some porting changes from the factory and went like stink.

Sherwin, did they change your chaincase oil already?

 

I know what you mean, we had a '99 mxz 670HO and it went really good. was our return to twins after a few years of triples.

 

Ah yes great to know someone who has actually worked on these!

I probably have the wrong terminology, I couldnt actually see the leak I just kind of assumed it was where if the rotary shaft seals (is that the right terms?) Heres a link i was reading to "problem solve" as best as I could

670 HO oil leak - DOOTalk Forums

Id take any info or knowledge you have on this though Colin! I dont know much specifics and like to learn!

I actually have been keeping my eyes open for a 98 670 x with reverse, and might end up having to go to edmonton to go get one. They dont seem to be around much here.

Marlon, where do you go sledding around here? What do you have for sleds?

 

Yes, they say its required at the 500 mile service. I had exactly 798kms on it. Today we put 265kms or so on, but its real rough. Time for more snow, and a more active grooming team. Out of the 265 kms, only about 30k was nicely groomed. The "powder" where I try to be is getting rough as well from the wind blowing and packing it. We found a few playspots, but we need about another foot or 2 without wind to make it real sweet!! Here's hoping!!!

 

Sheldon;
Those grommets under the oil tank are notorious for leaking. Like the guys in the forum said the drips could be just flowing down and collecting. Honestly, I have rebuilt over a hundred rotax rotary valve motors and only saw one bad rotary valve seal. Not to say it doesn't happen but pretty rare. You could have a closer look and maybe "bargain" with the guy about the leak.
The 670's were solid. We had a 98 MxZ at the shop with some porting and a few other tricks. Looked and sounded stock but there wasn't any other 700's and not many 800's that could touch it.

Marlon;
The 99 HO was so awesome especially for its day. Don't see too many out there for sale unfortunately. And I was a triple guy too (still am) but the 670 was a darling.

Sherwin;
Never heard of having to change the oil that early. Hopefully they didn't charge you to do that.

 

I think it was included in the 140$ cost of the first service... I dunno if its necessary or not, I should look closer at the work order, it was the salesman that told me that was part of the first service, I can't remember if the service writer said anything about it or not... Too flippin' excited to get it back and go riding!!

 

I ride a MXZ 700, just dug it out and brought it to the house in town. Haven't got it running yet. We used to do a lot of riding north of Langham and on the river but I haven't really done any riding since we moved to Regina. Even now that we moved back, I have lost a lot of interest in sledding. Much less time with the little one around.
