Well, I finished my major undertaking tonight. I shimmed the valves, YZ timed the bike, de-octopused the carb and re-jetted to Bill's YZ jetting specs. I only had time to run it up and down the block a couple times so far, but all I can say is WOW! I think I pulled a 3rd gear wheelie for the first time. (Im not good at wheelies) It seemed to run crisper than ever before. I was already thinking how the jetting changing and de-octopusing it might affect how lean its running so I pulled the plug and low and behold it was blacker than I thought it would be. Its probably just still coated from my WR jetting so it probably didnt tell me a whole lot. I have to admit, even though I LOVE the way it runs now, I still have reservations that it might run too lean and grenade. Im sure Im just paranoid, as always. I hope to take it out tomorrow and do some real testing over at a friend of mines house. Wish me luck! BTW: Thanks to everyone for all the help! You know who you are!!!!!!!!!!!!!!!!!!!!!!
