I would check the motor mounts, make sure there not cracked or worn and replace the actual rubber mounts. Have the clutches rebuilt, check your jackshaft and driveshaft bearings and chain and gears. Look for worn hoses, wires and leaks. This would be a good start as far as under the hood.

ok most of those parts i was planing on changing... i was also thinking of putting a indy 600 motor into it but im not sure if that will work or if its worth it. the 500 doesnt have a hole lot of muscle compaired to some of my buddies skidoos. i do alot of lake riding so i need some speed. if theres anything that could help the 500 pull a lil harder that would be great

its a 600 triple but there was also a 650 the frames and mounts loook the same from both the 500 and 600 so i think the only thing that will need to be changed are the carbs fuel pump airbox wiring and a few other thingss

As far as my knowledge goes it should not be to difficult. Is this 600 from a Indy 600 or a xlt, xcr? If your looking for more performance I would not use a Indy 600 motor. I would be more inclined to use the 650 motor you mentioned. I think the Indy 650 had more availble for aftermarket performance. I see 650 parts all eBay and craigslist. This is just my opinion.

yeah i was thinking the 650 is a better choice... i pulled the motor out today and the mounts look like they will be able to fit the 650 motor. the only thing that i think is gonna be dificult is a brake cooler. my snowmobile doesnt have a brake cooler and the 650 had a brake cooler. i might be able to just swap brake assemblys and it will work fine though.

Sounds good, another thing to be aware of is make sure your center to center on the clutches is right. I'm sure you may run into a few hang ups, but nothing that can't be worked out.

i will have to check the mounts from motor to motor to see if it fits because it seems to be sort of different. i hope i didnt get my self into a mess with mounts here :p

Check the rivets for the tunnel/running-boards.. these usually need replacing. Check the rivets for the skid torsion bars... these always need replacing, either bolts or rivets... good luck in the rest!

How easy do you have it when working on your sled- you have a nice garage and all? I say go for the 650, itll pay off alot more in the long run, you'll enjoy it more, and you'll learn more.

when you did this swap was mounting the motor very easy?

it wasnt simple. your adding a cylinder. You need the motor, carbs, airbox, pipe, y-pipe, can, clutch components, electrical, then you need to drill new motor mounts.

I did this with a cousin. it wasnt too hard. the Old indy chassis are simple.
