can a 20+year old school mod sled run with the new sleds? I think it can and will. so I'm starting to put one together this coming winter and summer and I need to find a lot of old school parts lol. I think that's going to be the fun part of it. I'm shooting for 440#- with 250+hp no turbo I might put nitrous on it 75hp hit so put me in the 325hp mark
20 year old mod

Not a chance. Unless you are just going to use the seat and tank and upgrade or "mod" the rest with current technology, even then the seat would still suck 
Wasn't impressed with any sled made before the mid 2000's then and most definitely not today.

What the hell I'll play along. The horsepower number is no problem. PSI used to pull gigantic horse out of their Genesis engines. Late 90's mtn sleds were 500-530 dry. That means you will have to pull around 80 lbs off the chassis while adding the weight of the bigger track. I would not want anything less than a 174 3. That will mean everything made our of titanium and carbon fiber. Let's say a guy has access to the means to do this and you can hit the weight mark. It will take a rider with the skill of a RMSHA guy and the strength of a NFL linebacker to overcome the chassis limitations in the trees. Keep up is a relative term. If you mean keep up on the big hills, for sure. That's about big tracks and big power, and that can be done on one of those.

Twenty years ago the biggest limiting factor for mtn performance was track length and lug height. Seen many sleds built to around 450 pounds with 150 to 200 hp. One of the problems I had with mine when riding in deep dry powder was keeping the pipes hot and filters unplugged.It was a 1998 s-chassis with 925 triple, van amburg ,diamond-s, jaws, boss, alot of shop built parts etc. I am sure it can done.

I've never weighed my 1200 but it's not bad, lots of titanium and go fast parts

There’s are a lot of older mechanical things I’m nostalgic for....sleds aren’t one of them. Like other said, getting the power out of an older motor is pretty well documented...putting a bigger track on, easy enough. But the riding dynamics just won’t be there. If you’re thinking hill drags or something like that...I think it would be easy enough. But not for boondocking or general fun riding.
I'm backed up on a few projects but not too far down the line I tink I'm going to do a wedge build. Just because it's nice to mix the old and the new
Remember when your building something like this, you might be able to buy one that's 80-90% built the way you want it all ready for pennies on the dollar you'd pay to piece one togather. Be a better starting point anyway!

it can be done, everything except the steep sidehilling maneuvers like elevators. also they will wheelie over on stupid steep stuff that the new ones can hang onto, as you are over the front more. you would have to chop into the footwells and get further over the front to prevent this. is what i found anyways.
I don’t think so. But for sake of watching U do it I say yes. I always liked old school builds

Somewhere between too dumb to quit and flat earth
Im at a solid 150 Hp on this 1998 msrx. Tunnel dump. Hot wires. Brisk plugs. Hand ported and port matched. Custom prototype fuel cooler, 162x16x2 track ported with screws. 2012 assault rear skid. Team second dairy, Fox evol xr shocks (still need to get Danny at alternative impact to build me ti trailing arms.
Sled is 530 pounds wet full of fuel oil tools going out the door. Spring set up with no hood and dropping boss seat in snow (I carry a lot of spare ****) should be easily under 500 pounds and lighter than cat and doo. Oh and other yamahas. Have some boondocker nitrous for it, plan to keep playing with this old muscle sled till I can pull one of those new 17 vipers ?
Can I ride it as a seasoned rider and put it places people on stock sleds can't? Yes. But if I was on their sled I could out ride this old turd easily. I have fun on it with some of my friends on new sleds that are still learning. But mainly it just sounds awesome haha
