I YZ timed my 00 WR and I don't think I like it. I expected it to have a real midrange like the YZ's I've ridden. But I seem to have lost the low end snap I used to have for a bit of a 2 stroke like peakiness. Yeah there is a little Mid hit but no more top end and the bottom is mellow when it used to explode off the bottom with WR timing. Am I missing something? My wheelie skills just went out the window with YZ timing! My mods are: Blueprinted head Full Ti-4 w' powerbomb Carbon fibre airbox. James Now BK mod gray wire 162 main, DRQ-4 40 pilot 2 turns out The one thing I notice is less stalling, I think I am riding the bike higher in the rev range and that is keeping me from blipping the throttle at low revs which I think used to load up the motor with gas causing stalls. I'm thinking of going with the JD jetting kit. Do you guys think that will help. I noted I had to drop the pilot with the James Now. With the stock 42 the idle dropped as the bike warmed up and I actually foulded a plug for the first time in 3 yrs.
