Just wondering if I missed it or if it exist, but is there a sticky here somewhere on what I can do to loose some weight off of a 02 mountain max?

How much can I realistically loose without ruining the sled? I would like to keep stuff like the e brake, hand warmers and keep it reliable.

Thanks
 

budget will be your only concern. there are lots of ways to save a few pounds here and some there, no real single diet item.

start with the skid. install a transfer kit, ice scratchers(you should have these anyways), and remove a few of the bogie wheels.
if your still running the 141, swap it out for anything, the yoko is an anchor
an aftermarket can looses several pounds.
pipes are a wash in the weight department but make up for it in power added.
lightweight trailing arms and steering components(if you go this route, use viper arms and spindles, takes the nose dive out of the mtn max)
seat
skis(powder pros)
remove the stabilizer
realistically you can drop up to 50 lbs, if not more
 
I really wish I would have done a before and after weight when mine went on a diet, but here is what I did, with manufacturer "claimed" weights.

Skid - Fabcraft (loss of about 30-35 lbs) Their 144 skid claims to weigh 46 lbs and a stock one I believe is in the 75-80 lb range
Seat - Boss (loss of about 9 lbs) Stock is 16 lbs and Boss is 7lbs
Front suspension - Timbersled Barkbuster (loss of about 10 lbs)
Track - A/C 156 camo from the Yoko 141. No clue, maybe lost a few lbs, but probably a wash. I think the 156 is in the 55-60 lb range.

Other items that will lighten things up are:

Hood - Stock one is around 17 lbs, aftermarket lexan is around 7-8lbs
Can - Not sure on stock weight, SLP for example claims 6 1/2 lbs weight savings

If your budget is endless, as snowdad alluded to, you could do a whole boatload of carbon fiber parts replacements. But at that point, it'd probably be cheaper and easier to just buy a new RMK or M.

There are other little things here and there that will save a few pounds, but that's the bulk of it. I'm guessing I lost, realistically 45-50 lbs.

Budget is something of a concern as stated I could just go buy a new or newer sled and be done with it for what I'd have into this one. But, I like the MM for the tripple power and looks of the sled. It's just too heavy for a real mountain sled is all and could use a few horses more.
I would realistically like to loose 30-40 pounds and gain at least 20-30 horspower (leave that one for another thread). If I had to choose between the two, I'd loose weight over gaining power.
So I guess what I"m really after here is what are the biggest weight reducers for the buck or something of an upgrade that also looses weight (like ditch the yokohama and stepping up to a camoplast or removing the silencer and adding a can).

Does anybody still make the light weight skid or skid peices for our sleds?

Thanks
 
For starters I got an mbrp can and stripped the skid. I calculated it to be about 20lbs there. I put on ice scratchers but was getting aggressive hyfax wear at the bend in the rails so i swapped to the rsi scratcher/idler mount and got a wheel back at the bend in the rail. I'm going to mountain performance light rails and a 144 track when this one wears out, for now i'm stuck with the yoki
 
Best bang for the buck is putting in a different mountain skid from one of the other manufactures. They will all cut significant weight and simply work better on the snow than the pro-action suspension. I've used Polaris ones with Holz coil-over kits and love the way they work. Helped a buddy with a couple of cat skids and that's a good way to go too. Never done a doo one personally, but lots of people have and like them too.

As for a track, I found the 144 to work well for me, but a 151 would be better for a true mountain only use.

Next up for me would be more power. Pipes and porting really wake that sled up and make it run. After that it's a matter of how much time, effort, and money you want to spend on it.

Search on snowest for used cat or polaris skids. Should be able to find an older one for well under $400. Look around for a used track also or sometimes there's screaming deals on new mountain tracks. I got my new 156 from a place in Minnesota for $350 delivered to my door, I believe it was called RV sports, or something like that. Add the pipes, again used, and you've got what you're looking for, a loss of 30-40 lbs and the extra 20 ponies, all for a grand or less.
 
Lots of threads and good ideas out there. First on the free side. If you still have one and you want a mountain sled loose the sway bar. Loose most of the idlers. Next one:MPI transfer enhancement kit ($50.00 -6lbs). But for true perfomance gain: Tripple pipes, handle bar rise, different skid. These will be a change that is most drastic and noticable. After that the sky is the limit. Speed costs-how fast do you want to go? :2strokes:
 
I lost 34lbs when I swapped out my extended stock skid for one out of an XP.
Adding HP will make your sled feel a lot lighter as long as it isn't stuck.
 
Not to dump on anybody, but I called Mountain Performance to ask them what they could put together for a price for light 144" rails, track, transfer kid and anti ratchet drivers. I was told to call Hartman Inc because HE DIDN'T HAVE TIME FOR ME! They don't do 2-stroke sleds anymore. How do you tell a customer to just straight go away. I would have gladly given them all summer to machine rails if they didn't have any, no crazy rush but how do you tell a customer to go away!
 
mountain performance

They may have been nice guys once. But I have recieved the same attitude and service from them. I wouldn't bag on them as much, but they can't even bother to update the website about all the things that they no longer carry. "Yamaha has not made a two stroke for years". Really really poor buisness plan. Guys who may start in two strokes will probably go four one day. I for one will not forget. :ban:
 
Tom Hartmann

Tom is a great guy. and he knows how to set up these "vintage" sleds to run better. He has helped me alot. But do him and you a favor if you have alot of questions like I did, call him off season. There is alot of information on this site if you just poke around, and follow threads.
 
Tom might be great, but the kid in sales that I talked to didn't want anything to do with me. Saying "um yeah we don't do 2 strokes anymore" I'm sure is not the attitude that the owner wants towards customers, its what I got though.
 
Maxco is referring to Tom Hartman, of Hartman, Inc. in Idaho. Call when the snow is gone and in the middle of the month when he's not in the middle of doing inventory. He'll answer all your questions.
 
Ok, I was discouraged by him not making one piece lengthened rails. I'm trying to avoid adding extenders since their so heavy. Only trying to go from 141 to 144 when this track is shot and I was to get a lighter 144. Maybe I can find some oem rails from an 03 viper and bolt them on.
 
sorry

Backwoods I didn't clarify this well enough. I share your total perception and annoyance with MPI. I was saying that you should instead contact a different more friendly company. Hartman Yamaha. Tom Hartman is a pretty good guy. Give him your buisness. Avoid MPI if at all possible they don't have time for you or apparently any other 2 strokers.
 
you guys finally figured it out. i have been trashing mpi's 2 stroke attitude for the last 5 years(yes, openly bashing an advertiser) and always have recommended hartman. (need to solicite this guy as a site sponsor)

no need to wait till the off season, tom always takes the time to give you his opinion, he will even call you back after hours and weekends, at least he does for me.

you wont get any better customer service along with knowledge, not to mention fit and finish of his products. the dude has had it figured out for years. been trading with him since 98.

208 468 1073. well worth your time.

sorry about dumping on him, I missed the subject line that says tom hartman. I do wish that he made extended rails instead of extension kits though...
