Hey everyone, I have a 1998 KE100 2 stroke bike with a rotary disc valve. I am experiencing thick white smoke from my exhaust and I've read that the oil seals could be bad and need replacing. I was just wondering which ones I should replace, and if I need to split the case to get to them. I have removed the covers on my bike and have attached a very short video of where I'm at. http://www.youtube.com/watch?v=v5N4FMveBN8 Do these crankcases need to be split on KE100's to replace the oil seals you would recommend I replace? I am buying them off of motosport: http://www.motosport.com/cruiser/oem-parts/KAWASAKI/1998/KE100/ENGINE-COVER(S)?mmy_source=oem On the engine covers section, I see one that goes into the rotary valve. On the Crankcase section, I see three that go into the left side of engine. Which do you recommend I buy? Only the crankshaft ones? Thanks for any advice, I'm new to this and trying to learn everything on my own but I've heard splitting the crankcase or removing the rotary valve could make the gears fall out and I'd have to re-time the engine, so I'm a little hesitant. I have the service manual but it has nothing about the directions to the oil seals, only that they should be replaced if hardened or leaking. Thanks for any help!
