Use a two-wire grounding switch like a YZ250 type and the KX250 switch also works well, I've never had a problem with those switches, rain or shine. I'd pull the clutch sidecover and check the kickstart idler gear to start. The clutch will usually be a little rattley but the noise will go away when the clutch lever is pulled in.

Look on the same website for the GasGas engine update for Feb 2008 and you'll find info on how to set the kickstart mechanism. When taking the sidecover off, it's a good idea to lightly tap on the kickstart shaft to keep it in place as the cover is pulled back. Did you ever get that water pump fixed?

pabowers Posted January 29, 2009 Author Report Share Posted January 29, 2009 Jon,I instaled the water pump kit you got me and it fixed my coolant leak.

The head of the capscrew is shaved down to give a little more clearance for the clutch servo cylinder to drop down into the hub. It is VERY IMPORTANT to use a new Allen wrench or an old one that has about 5mm cut off the end so that the flutes are sharp and will grip the center of the capscrew, otherwise you will strip out the capscrew and it's a bear to get at to back it out. Use a small hammer to rap the top of the Allen wrench (use a T-handle) to shock it loose and it should come out fairly easily (keep pressure on the Allen wrench while turning it). The capscrew shaved head is about half as deep as a regular one and really easy to strip out. Some riders leave the washer and capscrew out, relying on the pressure exerted by the servo cylinder to keep the basket pressed down as it makes it easy to get at the shift shaft centering mechanism in the field but I like to keep them in. If the hub still sticks you can carefully use a couple of slotted screwdrivers on each side of the hub to lever it out slowly and be careful not to damage any parts or sealing surfaces.

Yes, the idler gear with missing teeth can make that nasty sound..... Jon Quote Link to comment Share on other sites More sharing options...
