I just finished putting together my bikes top end and remembered reading in my manual about cleaning the exhaust power valve( I think it's called KIPS) anyway, I took off the cover, saw a black greasy mess of what looked like burnt oil but had no strong smell, and put the cover back on. I decided to seek out some more information. I plan on buying a service manual but since I'd like to be riding by this weekend I'm hoping to get some fast information on here. Is the job as simple as disassembling it, cleaning it, and putting it back together the way it came apart? or am I going to have to re-time it for the correct RPM to open? Is it REALLY involved or simple like a carburator? What should I use to lubricate everything once I put it all back together? Thanks alot for any information. I havn't been riding in 4 months so I need to get this together or you may be reading about me in Sunday's paper........... (the bike's a 2003 kx 125 btw)
