04 WR 450, Canadian version It had the stock exhaust uncorked, the air box cut outs (never had a snorkle), and grey wire cut (debate on if that actually does anything on the 04 Canadian bikes), and there is no AIS from factory. Jetting was stock, and the stock main was a 160. Started to smoke a bit at high rev's last year so figured it was time to get into the top end.....no other issues. Put in rings, honed cylinder (Cause of smoke..), new Hot Cams, valve seals, gaskets, etc, and cam chain, timed to spec, valves adjusted to spec (as per the "Cam Card" which came with cams...), added a FMF Ti-PowerCore, and a adjustable fuel screw.Went to a 168 main, and fuel screw is 1 3/4 turns out as a starting point. Starter decided to kick the bucket...I won't get into details, as this will be long enough, and I'll worry about the starter later, but we did confirm it is a starter issue, and nothing to do with top end work. point is, this is why I'm kicking.... Used to be: Fuel on, choke on, 2 twists of throttle, magic button, good to go. Now, the bike will flood pretty much instantly when kicking, even if you do not touch the throttle! We kicked our guts out, and there was gas running out of the carb in short order. Noticed petcock was leaking, layed bike down to change, lost all fuel in bowl, stood bike back up, fuel off, kicked a few times, fired right up. Idles good, throttle response seemed good....let it warm up, shut down for a heat cycle.....tried starting again, just to see, fired on first kick. Let bike get cold, went to do another heat cycle, same thing....flooded all to hell...bump started, bike fired, got another heat cycle, shut down.....kicked bike, fired instantly. Next day, tried again, did not touch the throttle, choke in, choke out, tried everything, bike flooded. Bump start away we go, bike fired. OK, so, we figure the jetting CAN'T be that far off, we got three heat cycles on it, figure it good to take out on the street and just check throttle response, idle, lugging it down, etc, while still being a bit careful with engine....a couple quick half throttle twists from idle to half throttle....monster power! Instant response, no bog, no stutter, instant wheelie! 2nd, 3rd gear.....instant response....instant wheelies....it's a tractor on the low end....lug the crap out of it, in short, it's just plain ol awsome! Shut down....first kick, bike fires. Cold starts though, it's impossible, and a nightmare. We checked the float, played with the adjustable fuel screw....nothing is helping.... The only thing else I have to offer is that we are kicking it on the side stand. Tomorrow I'm going to do a real 30 min break in ride on it, and then pull the cover, check valves, timing, etc.....and I'll try kicking with it off the side stand, with bike straight up. I only mentionthis because i have seen the older XR 600's flood themselves to death when being kicked on the stand, but have never heard of a WR doing it.. Anyone have any idea's?????
