I know this is getting old but I read alot of the posts about jetting and think I am more confused now then ever. I have a '01 WR426. It is stock except I removed the airbox lid, ground down the throttle stop, cut the grey wire, & removed the exhaust tip insert. After this "uncorking" wouldn't it be logical to expect to need a rejet. I was think about going up one jet size on the main and pilot. (that would be a 168 main & 45 Pilot) Is this OK? What do the experts recommend? What about the pilot screw? It runs ok as it is with some minor popping on decel...need advice!!! Thanks.
