    No, I haven't really made any mods. I've seen people do it, but the gains are minimal. The usable suspension will still be 4" tall, unless you replace the skid. If you ask me, if you're worried about getting stuck, while the tunnel clearance is an issue sometimes, I found that a good 3/4" lug track vs. the stock track does wonders. And if there happens to be a time when your tunnel is on top of the snow, and your track isn't touching, it's light enough to move out of that hole.

    Then again, if your talking about raising the seat, also something that I haven't done, you might get disappointed. If you do put the effort into a raised seat, it probably won't align with the gas tank cover, and the handle bars would be too low.

    I bought my new track for $365 new. It is very worth it, and an easy change, as long as the speedometer housing comes off. The stock tracks suck, they have a .4" lug that is crap for traction.

    You might be able to find a used aftermarket track in good shape for around $150. The track is 116" L 15"W with a 2.52" pitch. Early phazers took the same track as well as a few other machines.

    Alright. And I just saw the sled yesterday. Track is DONE! So I would have to put a new track on. How difficult is this to do on the 440 and is it still worth it? No biasy please! Ahaha

    Comet 102C clutch, New Aean pipe, convert to dual carbs, oversize pistons, are some things that come to mind.

    Sick! Anything you suggest tommaximize power andnto improve the 440? just any mods or upgrades you can think of?

    No, I have't ridden the 250, but I have had my 440 on 1 cylinder (burnt the motor, no cooling fins on the head) and, well, there was no comparison.

    I have had the sled up to about 85 MPH - with more throttle room. It's scary going that fast though, after hitting a small bump and staying in the air for a few seconds, I backed off. You'll have a blast on the 440 though.

    One thing I must complain about is the track. Yamaha used this track for a decade or more, and it lets you get stuck a lot more. I have bought a new track for this reason.

    You might want to tune the clutches appropriately. The secondary spring preload and spring hole locations could be adjusted, as well as weights and springs in the primary.

    Well, at least there easy to get to. And I have a spare crank lying around, which had those two bearings replaced? It should be running again inside of two weeks, largely depending on the shipping.

    Turns out that bearing is okay, it's the far PTO bearing thats bad. The cage blew up, and managed to get a piece through the bearing next to it, slipped through the counter weight, where it was sucked up into the combustion chamber.

    Rebuilding my engine, again. The engine is bullet proof, I can tell you that. It practically ate a bullet, smashed it up, and spit it out. Piston and head are wrecked though. I had a gut feeling that a crank bearing was bad for about a year now, I was hearing a shhh noise, really loud, and high. Turns out, I was looking through the hole in the counterweight, and the bearing cage doesn't move. A year, with a frozen bearing, but it kept on running.

    Oh, and when it ate the piece of metal, it never quit. I think it happened this summer, I heard something ding, in there or the primary. I checked the compression after I looked and it was still 133PSI
