first of all what does the compression release valve do?
The compression release holds the Exhaust valve open while you use the pull starter to make it turn over easier/faster.
when i ride it for a little while it fouls a plug when i try to start it, and sometimes i cant get it started and some times it starts right up. i have to change plug all of the time other wise it wont start
Is the plug wet with fuel? If so then take the carb off the bike and clean it (you should do this no matter what, since it sat so long) Inspect the carb real good when you take it apart and see if the needle and float are sticking. Make sure it has the propper jets in it if the engine is all stock. (main jet is a 100)
thirdley, can you buy seperate head gaskets fort the motor? if so where at?
YES. Bike Bandit
or Hyper parts
Since you are removing the head anyway I suggest getting the "top end set" from hyperparts.
i want to take the head off and port it and then put a xr200r camshaft in it. will that affect the jetting at all
YES! Stock is a 100, I would start with a 108 or so and you will have to test it! If you do the XR cam you will need to give it more fuel and better exhaust to work with the cam.
the timing rotor inside the circle thingy on the head where you can adjust the timing, whicgh way do you turn it?
There are 2 plugs on the lower left side cover (one in the middle side and one in the top. Remove both of them. The one on the side is to turn the engine over with (counter clockwise) Turn the engine over until you can see the "F" in line with the pointer in the top hole. Then set the rotor (the thing that spins in the "circle thingy: [img]i/expressions/face-icon-small-happy.gif[/img]) in line with the pickup (just align the 2 lines)
There are 2 set points you can see in the top hole....The "F" is to set "fire" and the "T" is to set the cam at Top dead center.
when the manual says 2nd notch for the needle clip position does that mean counting from the top or from the bottom?
You should set it in the 3rd groove, #1 is at the top(flat part) of the needle The higher the clip, the leaner it is.
thanks in advance
