You can start with a can, mbrp makes them, it doesn't add really any power but you drop about 10-13 lbs. Make sure to get the good belts from skidoo, not the crappy generic ones. As far as mods;

- A clutch kit will help you TONS, as will dropping the driven gear down 2 teeth.
- You can gut your airbox, just watch your plugs to make sure you don't start running too lean.
- Open filters are an option, but mean alot of rejetting with temp and altitude.
- A carbon fiber rotary valve will increase throttle response.
- Shorty carb boots and a RAVE valve cleaning/rebuild helps
- Loosen your track (don't go too far or it will start slipping)
- Probably out of your price range, but Weisco makes a .040 over piston for that motor ;-)

Just drop a tooth or two on the top gear. It will wake it right up down low. Cheap and easy. Two teeth might require a new chain, though, so that will add to the cost.

your rave valves should be cleaned EACH season. if they have never been cleaned, they are stuck/siezed for sure and they are not functioning like they should be.

My cousin has a 96 FZ 583, he installed a fat boy pipe, a stiffer secondary spring and a better track and that thing will run to 70 w/anything, f7s machs it dosent matter. Which rear suspension do you have? Boivin? The original sc 10 was not a good steering, but boy did it hook up.

the boots are a stock part on a 1995 mach 1 670. on my s chassis i used these boots, but had to slightly tilt the air box back. made a spacer just on the top of the carbs between the box and carbs out of vacume hose. without this, the air intake is restricted where it goes through the hood. 02_05_06_1535.jpg

I had a 94 STX with the 583. Milled the head and jetted and that thing ripped. Add a clutch kit and you should be smokin!

speaking of dropping gears, do you need a new chain for a 1 to 2 tooth drop? if so, how do u know which size chain to get?

if you pull the airbox off and look at the mouth of the carbs, there are 4 carb vent hoses,2 on each carb. they come up and over the top of each carb and go through a notch in the top of each carb. on a 583 you will need to relocate these hoses to some where above the notch. i cut 2 pieces of 1 inch rubber hose i had kicking around slightly longer than the notch. i flatened the hose and tucked it into the notch where the vacume lines were. this spaces the top of the airbox where the top carb mouth meets away, and with the bottom part of the carb mout is still close to the carbs. the tilt of the airbox was damb near perfect, and the hood opening matched great. most of the sealing between the box and the carbs is around the outside of the mouth, so tilting the box did not cause any sealing issues. this is one spot that i think is overlooked when installing shorter boots on s chassis. quite a bit of the opening gets blocked. i will have the sled out of the trailer in a few days, so if you still need some help i can snap a picture if unsure.

thanks! I think I have it, but if you can snap a pic that would be perfect! what was the overall affect of the short boots? throttle response, right? was there a big difference? thanks again!!!
