[QUOTE="Ol'89r, post: 1196405, member: 17212"] Simon. It would be wise for you to wait for your manual to arrive. Sit down and read the manual. Then, read it again. :cool: Sounds like your engine needs to come apart. The water in the crank would indicate a bad head gasket. The water in the gearbox would be a bad water pump seal or possibly a hole in the right side cover behind the water pump due to corrosion. If the bike has sat for any amount of time with water in the crank, you should have the crank rebuilt. The piston should rock a little bit at the top, but not 1mm. You need to remove the piston and mic it at the bottom of the skirt. You should only have somewhere around .003 inch clearance at the bottom of the piston to the cylinder wall. If you have 1mm clearance, that's about 10 times too much. If the piston has the proper clearance and has not been seized or damaged in any way, you might just need new rings. When you get it apart, you can take the piston and cylinder to a shop and they can mic it for you if you don't have the proper tools to do this. The cover that says HPP on it is your power valve linkage. There again, you will need the manual to set this up properly. Good luck. :cool: [/QUOTE]
