Ive got an 03 900 1m 151 and was wondering what was the best way to lighten this thing up a bit. How much does the mseries rear skid help?
Thanks

Best ways to lighten up the 1m.

I just took off another 2.25 lbs. off the old '03 151. Got ahold of the front Titanium spring and made a new aluminum shaft at the bottom in place of the steelshaft/thru bolt. The short rear flap is worth a lb. The rear rack is close to 3 lb. Take the windshield off is about 2+ lb. I have a modded set of stock skiis that are .5 lbs. lighter ea. Every nut and bolt is looked at for a lighter redesign if possible. I have spent countless hours redesigning things, But it is 50+ lbs. lighter than stock!
Hope this helps

How much do you want to spend..............
The sky is the limit here. I feel I have done okay with just a couple of things, and haven't sacrificed any integrity. If you get things too light you will start to break stuff, you have to decide what is important to you. I bought a lightweight hood, seat and muffler. My kingcat weighs 503 without fuel. It is mostly stock. The hood is huge! Not only for the weight, but the handling too. Could I buy some more light parts? Sure, but Id rather ride, and I weigh 250. So the best weight loss for me would be a diet! -00's

Hood is definately big. Hit up Mountain Fit or BR Tech. Different seat is a must. Take the stock heat shields off the pipe and send the pipe to a ceramic coater. Y-Pipe and can too if applicable. Biggest savings right there. After that, do the mods that fit your riding style and that will keep you smiling day in and out. I'd swap skis and upgrade the suspensions next. Forward post and a new rear tunnel extension or mod your existing. It goes on forever.
There's some excellent info on here.

Diet
#1 Seat-Ditch it get a lighter one
#2 Lose all the bogie wheels on the skid and get scratchers
#3 Mountain Fit Hood
#4 Exhaust -go single pipe and a can
#5 13 wide bottom gear
#6 Extroverts
#7 Oil Injection-go premix
If money is burning a hole in your pocket then invest in a skid-KMOD
This will make your ride under 500lbs easy
Mine is 484lbs full of fuel (2001)

Who should cut weight
On my M6 I spent alot of money loosing weight. Then last year, I realized the my two cousins with their ski doo 800's dont neccessarly go anywhere I cant. I weigh about 160 lbs. Thats an easy 20 to 50 lbs less than most the people I ride with who have bigger motors. And with my riding style, few in my group can side hill or carve as well, they count on the motor to get them there, I have to work a little more.
Now I have a 04 900 151". I dont think I'll spend so much on weight loss on my sled and consintrate more on me, no weight loss but more muscle to get the sled to do what I want. Efficency is Key, for sled and rider.
My list so far
Port track
two wheel kit-its cheap
chop up my tunnel
maybe oil delete- its cheap too.

The skid is all the weight, Remove both shock mounting shafts where they mount to the skid. The rear contains the wheels and shock pivot. Both have steel shafts, When replaced with aluminum will save 1.5 to 2 lbs. the rear rack is worth almost 3 lbs. The rear flap with a shorter factory replacement is 1 lb. Two wheel kit 3/4 lb. Take off front outside wheels and replace with 2 2.75" crossshaft idlers. Front ski steel bushings and shaft when replaced with aluminum is worth 3/4 lb min. This is just a starter, But you get the idea! You can do a lot yourself and save on the BIG bucks weight loss! All replacement alum. is 7075-T6/T73 for strength and wear resistance. You have a extra .625" shaft on the front of the skid, Use it in place of the shock shaft! One shaft upfront is enough. Also move the skid stiffening plates to the inside, By swapping sides and shorten cross shaft by .50" Looks cleaner!

Just ride it

I picked up a clear LW hood brand new for $60, I mounted my tach and a 55w auto bumper light, 5 piece vent kit from Mountain tech windshield and bag,
I lost 8 lbs doing that and could go 10+ if I lose the windshield and bag.
Hood - 65
light - 15
vent kit 45
$125 for 8 lbs = $15/pound
I should just hit the gym!!!!!

More power makes it feel lighter!
I'll second the bit about being 160lbs and keeping up with 800's on my bone stock 1m600... My riding buddies are 200ish, so I'm already 40 lbs lighter. Dang new sleds from Skidoo are killing me though, as they're at least 40lb lighter than my old school 1m. Takes them back out in front, but I still get there, I just have more fun doing it!!
It is amazing how much $$ it costs to loose just a little weight... Well, a little can be free, but for more than about 10 lbs, you really gotta turn up the wallet... Why snowmobiles must be so heavy is beyond me...

How about weight management instead of reduction?
Ok, weight reduction in significant amounts turns out to be expen$ive...
New plan: Weight Management!
I have two 2-ish gallon cans that snuggle well in the stock rear rack, and stay put with a lashing strap over them. This year, on the steep and deep rides, I'm going to short the tank by about what those two cans hold... I think that's about 25-30 lbs of fuel. If we get to a hill I'm having trouble with, I'll offload the cans in a nice hidey-hole and give it my best... Assuming I burn a few gallons getting there, I'll be quite a bit lighter this way...
Requires a bit of involvement, but should help a lot. Plus hopefully the extra weight on the tail will improve the ride some on trail too... Just have to take it easy in the whooped out sections when the cans are full. On the way back, dump em in the tank and it's hammer time!!
With the 600, I've never even come close to running out of fuel, particularly when I'm running with heavy guys on fuel hungry 800's!!
