700 RMK lost oil pump?
I have a '97 700 RMK with HOT SEAT heads and clutching, psi pipes, variflow jetting(accs only manual), pyros and boost bottle. I have about 400 miles on the set up and it is jetted perfect. I run it a little on the cold side just so I don't have to worry about losing jug/piston. Much to my disappointment I lost my oil pump! That's correct, I've checked everything. We tested the oil pump by using a high speed drill and we could not get any oil to flow, not even a drop. So we checked the supply line, oil was running out of the line and there were no clogs. So we tore the pump apart, nothing that we could see wrong with it. Stuck it back together ( the oil pump) and tried testing, again we got nothing out of it. We thought that the pump had gone out because I lost a rod bearing. I was watching my pyros all day long and they were perfect. checked the plugs immediately after I heard noise and there was no sign of aluminum what so ever. Pistons would have been great except for one has what looks to be a factory defect crack on the intake skirt! And thats on the mag side, I lost the rod bearing on the PTO side. How ever, the jug on the pto side is losing its nikasil lining. Its starting to flake off at the very top of the jug. This also looks like its some sort of defect. Oh yeah, I've got a TOTAL of 2,000 miles on my sled. So my question is WHAT THE HELL IS GOING ON!!!! I've talked to a few dealers and they say they've never heard of an oil pump going bad or nikasil flaking off, but they "thought" that they'd heard of defective pistons. Has anyone else had such good luck. By the way I am fixing it, I do feel that its worth it.
