    2001 gp1200r

    Hey everyone...New to the forum and have been searching for an answer, any help would be greatly appreciated.

    I am rebuilding the motor for my 1200r, traded cylinders from SBT, have new pistons rings, etc... Also have installed a ADA Racing 40cc head, converted to premix, and D plate. Have flame arrestors coming, hopfully soon.

    My questions is, im reinstalling the powervalves (and will be putting the wave eater clips), and the sleeve that the valve slides in will not flly go down into the groove so that the retainer screw can be installed. It stick up by about 1/16th of an inch or so. I took the powervalves out in order and labeled them so I knew which cylinder to put them back in, but the sleeve for the front cylinder is brass (or looks to be), and the other two look like stainless, I comapred them side by side and the stainless ones are a little longer. The brass one fits in fine. Im guessing they should all be brass and set flush with the housing. Any help on the subject. Or is there more info needed.

    Thanks in advance for any help.

    Welcome to the Hulk.

    It is Ok for the SS ones to stick up as long as they are retained by the screw. Add some loctite 242 to the screws.
