Hey folks, My 2001 WR426 will have it's first engine work this winter and I need some advice on what parts I should order before diving into the engine. Some background: The bike has never had any engine work done since I bought new in fall of 2001. Estimated mileage is somewhere around 7000 miles of singletrack. The valves were still in spec at the beginning of this summer and runs (ran) perfectly. I have been burning some oil on initial startup, but not while running. Because it was only at startup and not continuous, I am assuming this is probably the valve stem seals since I had good compression and no problems starting or running. Last month I fell over in a water hole and wound up sucking water into the engine while trying to kickstart the bike once it was on dry land. I only tried to start the bike for 3-4 kicks before realizing what might be wrong while waterlogged. The entire airbox was full of water as the drain had gotten plugged with grime over the summer. I have been unable to start the bike and steam out excess water because I have lost compression. I can push through the compression stroke with my hand, without using the decomp lever and the plug installed. I changed the oil several times, flooded the bore with tons of WD-40, and regularly roll the kickstart over with my hand to keep the bearings and such oiled and hopefully free of any corrosion. I figure I will do new piston rings, valve stem seals, and obviously new gaskets for the cases. What else should I plan on replacing as a normal "preventative maintenance" sort of thing while the cases are split. Is there a "top end kit" available and what might it include? I figure I may as well refresh things while the engine is out and apart. If anything like bearings or other parts that are not typically needed to be replaced during routine engine work are damaged, they will be ordered afterwards. Hopefully during the week between Christmas and New Years, TrailriderJoe and I will have the bike back in tip-top condition. Thanks a ton for the help.
