How light can you make a Nytro?

[swelly]

People were having issues with the skinz kit using the origianl 1/2' and updated 1/2" heim joints. Not sure why they did not just recall and replace the 1/2" joints in the first place but there are still people out there that are riding on them with no problems. I for one wouldnt be.

I think you would have a really hard time finding someone with more miles on there Skinz front end than me and I'm still running the 1/2" heims. There is more to the storys than I was just riding down the trail and it snapped. The only one I snapped I am fairly confident something else would have broke if it didn't and with just the snapped heim I was able to re install it and ride it out.

And we all know if anyone could truly field test something it is you. We all know, no matter how much testing is done, it will never compare to the real world. My sled is a good example to the toughness of the Skinz front end. Direct hit from another sled, front end fine, sub frame bent, shock broke. Plus I am still running the 1/2" joints.

The skinz front end in particular has had some well known issues with heim joints and there's been some issues with various light weight batteries.

I had the Skinz front end with updated 1/2" heim joints and the Ballistic battery all season. Zero issues...

That's great, but I think you'll agree that just because you didn't have issues doesn't mean no one else did. I know guys who have 2500+ miles on their pro rmk without issue, it doesn't mean no one else had a problem.

Rick, I have not heard of an issue with the 5/8 update but I honestly haven't been following the topic very closely. They may very well have fixed the problem now. My point was the OP said he likes the low maintenance needs of his stock nytro, and putting on aftermarket parts will increase the maintenance required. If a person bought the updated skinz kit it might not need any work, but for the people who bought the original obviously it wasn't as problem free for everyone as it was for Alatalo.

My argument on the heims is that Yamaha obviously I have the most experience with. There lowers are sloppy are way sloppy after 500 miles and they are extremely expensive to replace. My Skinz has worn better than the OEM ones and when I go to replace them I can use whatever grade or quality I want. If I spent the same as a oem joint on a joint for my Skinz front end I would have a far better Heim. For similar quality as OEM it would cost me 1/4 as much. Not to mention being far easyer to replace. Obviously I have not near the experience with other brands but I've got a IQR, IQ, Pro and Rev front end in my shop and every one has sloppy joints. To me I see benefits not problems to the heims. If the 1/2's were a problem, it's been resolved and is no longer a issue.

Not all Pro's are blowing up, but answer me this. In your honest opinion whats the percent chance that I could make it 2 seasons on a pro with out a engine failure? I ride at least 1500 a season. I hate the fact that I would buy a 10k plus sled and go into the second season basicaly knowing it will blow up. Obviously a long warranty is a must on any new 2 stroke, but what does that do for getting your sled out of the backcountry or for lost riding time? My other big issue would be loosing Anchorage Yamaha as a dealer, how many of the guys with any other brand sled have such great service 5 min from my shop? When I do buy a new sled I really hope yamaha will have done something so it can come from there.

Good luck with your battery, mine is sitting on the shelf with the other top 5 biggest wastes of money I have spent on my Nytro's.

You going to give us a countdown of them all? I would be curious to know what else you think is junk out there..

First, Anything that says BDX on it.

The rest are in no particular order.

VE heat exchanger delete kit, it does work but they should be embarassed of the quality of there kit. The coolant plumbing went in the garbage and I made my own. Even paying myself a typical shop rate of could have made my own cheaper of far greater quality for the actual delete.

Team Tied clutch, it's a great clutch but they have not done the testing on a Nytro so it's left to the consumer to do it using expensive custom cut helix's on top of a 700 dollar investment.

The battery has alrea been covered enough.

Off the top of my head I can't think of any other big items, there have been many small trial and failures but those are the main large items that come to mind.

This is the only part of your post that relates to the thread topic in anyway so I'll skip the rest. I'd say the odds of a pro motor making it 3000 miles are about 10:1. Of the the THOUSANDS of pro rmks on the snow I know of less than twenty that have lost a motor. I'll assume I only know of 1/10th of the problem, so even if there were only 1,000 sold your odds of going two seasons on one engine are pretty good. What are your odds of going 3,000 miles on one sub frame on a nytro?

You do raise a valid point with dealer service, it's always something to be considered. but if AKrider doesn't like his nytro, having a good dealer won't really make it any better.

All of these newer 2 stroke engine run so lean I'd recommend an extended warranty. And none of the other 3 compare to Yamaha reliability or fit and finish. First thing I did on my Pro when I got home was turn the oiler up substantially to get the oil to a sub 40:1 ratio to gas. I think there'd be less issues with the Pro's if all dealers did this as a matter of course during the pdi. But it's probably illegal too and you ha e to remove the pipe, so it's a pita. But most are coming from the factory like 70:1. Polaris is assembling these engines way to lean for emissions. First thing to do IMHO is turn up the oiler. It'll help.

But I'm telling u. The Pro runs like dream and it requires no modifications.

I wish yamaha made a sled comparable, I'd rather have bought a Yammi.

From what I've read and seen, the Polaris 800's have the most problems but their 600's are not free from issues. Like was said, the EPA requirements make Polaris lean out the engines. I don't know if turning up the oil injection is the cure or not? In a perfect world I'd just buy a new 2-stroke 800 every year and have a buddy with a helicopter that would airlift my burned down or blown up 2-stroke out of the mountains for a case of beer.

I like reading all the different opinions and have been mulling this over in my mind for the past week. Right now the reliability of the Yamaha motor is first and foremost in my mind. I've resigned myself that no matter how much weight is pulled off the Nytro, it will never handle or be as easy to throw around as a 2-stroke. Thinking about the conditions my buddy's like to ride, nothing is ever that technical so unless it is bottomless powder, I should be able to keep up with their 800's on my Nytro with a longer and wider track.

For the tight, technical, tree filled, short steep hills in the areas I like to ride in, I'd be happier with a 600. But I can't have both so I think the Nytro will be the most versital choice. I'm thinking the larger Nytro engine and its greater gyroscope effect will always make the sled feel and handle heavy. It looks like a guy can remove a lot of weight off a Nytro for free or for low cost. I need to pencil things out to see what makes the most sense financially. My suspicion is just buying a leftover 600 Summit sport would make the most sense, but that's just my gut feeling. I saw AMDS still has them available. I've ridden the XP's and thought they handled fine. Maybe they are not as good as a Pro-RMK but they are way easier to throw around than a Nytro.
