Hey Guys
I can usually fix anything--and I dont know alot about how these clutches work---can anybody explain or link me to a sight?? i am not sure what you mean by shifting clutches out---tee me up and I'll give it a shot---good friend of mine has a machine shop and he owes me a favor---

Hey Moses,
That's what I wanted... Skid plates, and that kind of thing. My 360 does close to 50... Not sure exactly yet but I'm getting the speedo installed soon. Speed isn't what I bought mine for and honestly the trails on my property aren't drag strips. As far as jetting, jeez.... I wouldn't know how to do it and I'm not going to do anything that would void the Extended Warranty. I'm not a mechanic. But yours sounds like it has some of the stuff I'd like to have on mine.

OleManMoses - Fully shifted out means that the primary clutch is together as far as it can mechanically move and the secondary clutch is as far apart as it can mechanically move. This is the highest ratio the machine can get to.
To check this you pull the clutch cover off and mark a wide band up the clutch faces with an indelible ink marker. Take the machine out and make a top speed run. Pull the cover again; the marker will be rubbed off wherever the belt was contacting it. Pull the belt off, push the primary clutch all the way together, and lay the belt in the gap. If the belt goes down into the primary far enough so that the top of the belt is level with what's left of the black mark you had put on the clutch face, it was fully shifted to the highest ratio. You check the secondary the same way, except everything is in reverse (push the clutch APART, BOTTOM of the belt even with black mark). You probably wouldn't have to check the secondary, they usually shift out a little easier than the primary anyway.
If the clutches are not fully shifted out, either the clutch springs are too heavy, the primary clutch weights are too light, or the engine has simply run out of power.
If the clutches are fully shifted out and the engine is revving at a high RPM, clutch modifications may help. This just means disassembling the primary and removing 0.03 of material from each clutch sheave where they come together at the bottom. It will also involve minor material removal from the primary clutch cover to allow the weight/spider mechanism to move far enough to allow the modded clutch sheaves to go all the way together.
The clutch modified as such will be tighter, thus pushing the belt higher in the sheaves and creating a higher ratio. On P650/700's this is good for another 5-10 mph. If the 360 has the power to to take advantage of the mods, you should see similar gains.
If you are serious about trying this, talk to Alltoys or reds650. They have done this and have a good handle on the technical side of the modifications.
I hope this is of some help - it would be great to someone cure one of the biggest complaints about an otherwise great machine.
