An aftermarket pipe increases power by increasing air flow. This will cause a lean mixture. You need to compensate by putting in larger jets. There is no rule for what jets to put in. If you don't know what your doing, this isn't something you want to tinker with.
Ask someone who knows what they are doing to help install the clutch kit with you, along with the carbs. Or have a dealer do it.
Absolute excellent advice Sno-X-Treme. Do not F*#K with your cluth, jets without knowing what you are doing....FOR SURE! Engine melt down, loss of money, general pain in the @ss problems will result unless you do these upgrades correctly.
The mods you talked about have to go hand in hand. When you put a pipe on it, it will change the RPM that your sled makes it peak power at. With that said the clutch will have to be set up to allow your engine to run in that RPM range. The jetting will have to be adjusted to match the increased flow of air through the engine as stated by Sno X. The best way to figure out a ball park settup would be to talk to a tech from the pipe manufacture. If you do these mods I would go with a D&D pipe. They are one of the most experienced with Cat settups. If you decide to do these yourself you'll need some specialized clutch tools for removal, disassemble and assembly.
I just installed a Goodwin Performance clutch kit on my 2001 zr600EFI.
It is not too hard if you have some knowledge of sleds or mechanical skill. You do need a clutch puller tool and a torque wrench for when you re-install the clutch. My kit came with new wieghts, new primary spring, new driven spring and new helix.So I pulled the clutch off the shaft CAREFULLY . Removed the cover of the clutch,(everything is under spring pressure) replaced the weights and spring.Reinstalled the clutch (should be torqued to 55 ft lbs) Then remove the driven setup unbolt the helix cover and helix . Replace spring, install new helix. Putting the spring in and tightening it down is the tricky part. MAKE SURE YOU MARK ALL PARTS for alignment before you dissasemble them.
Dude, don't get offended but you don't even have what sled you want picked out yet, let alone how to do what mods on it. First you need to decide on a sled, then ride it for a while stock....you may find you like it best that way. Then, if you still feel that something needs to be changed, go ahead and do it! Don't put the cart before the horse buddy.
