I have a 99 cr125 that I pulled apart to clean the power valves. When I took the covers off theres oil covering everything and literally oil sitting in the pocket where the pinion shaft comes up through. I also have quite a bit of oil leaking out from where my pipe connects to the cylinder. Is this semi-normal? Is it running way rich?? (Plug has good color but really wet). Or do I have other issues? Thanks for help in advance!

Crank seals may be leaking.

Normal. Just clean and inspect everything per the manual. The HPP powervalve system is pretty complex to service and rebuild but not too bad if you follow the steps.

yes normal but also change to a aftermarket exhaust manifold. Kart shops sell them and theyre inexpensive
