'99 WR400: Spent the last 1 1/2 years gathering info and parts. Went from stock with airbox lid removed and throttle stop cut to: (all in one shot): 1) YZ450 exhaust cam (modified timing) 2) Big Gun tapered exhaust 3) P-38 accel. pump housing 4) Grey wire disconnected 5) YZ needle ('99) 6) Stock YZ jetting ('99) 168 main 45 pilot, then: 7) Better YZ jetting: 162 main 40 pilot 8) James-Now mod 9) air screw 1 1/2 to 2 turns out Results after 3 days at the track: 1) EASY to start!!!! Love this!! Could do cartwheels about this!!!!! My kid can start it now!! 2) Snappy 3) Cuts out mid/high (sometimes?!) 4) I'm not honestly real impressed with the power delivery. I wanted to be "scared sh!tless" I guess... instead I have to "intentionally" work for a wheelie..? Big Deal... It did as well or better before... Maybe the modified cam timing doesn't help? It is supposed to be in between WR and YZ "hit". There just is NO "hit". I don't seem to have the "rheostat wheelies" (dial in your favorite height with just the throttle) that I used to. 5) The bike really sounds cool!!! Parameters: 1)I am NOT that good a rider. 2)But I DO know how my bike has always ran (basically stock) and ability has never dampened desire. I go hard till I crash and then try it again. When I crack the throttle, I want that baby to LAUNCH! 3)The still-stock suspension sucks so bad that at 60mph the headshake was so terrible that my 9 year old on a KX 65 fed me rocks!!!! I HAD to back off, and NOT 'cause of the rocks in my face; the bars were being ripped from my hands by headshake!! Same story on the track: (The 60mph+ was on what most would call a "fire-road".): No control. And, yes, I DO have an accurate speedo. I say "stock" suspension meaning: nothing more than the max oil level in the tooo-soft-bottoming forks; which has caused a major oil seal blowout I discovered via the puddle on the trailer floor after the trip to the track... I also have @ 1" left of the threads on the rear shock to gain "recommended" sag. The throttle response is initially good. Craps out part way through (SOMETIMES) (like hitting the rev-limiter at mid-rpm). It never needs the hot start. Starts real easily even when doing "50cc patrol": meaning riding a little ways, shutting it off, waiting for all the little guys to pass (maybe helping a couple), then moving to the next "trouble spot"... Hard on any bike, I know. That is why the starting impresses me. It never fails. I also know that all the power in the world is useless with crap suspension, but I really have doubts about spending big money on suspension for this bike when all the power-mods don't impress me more power-wise. I read what everone says... I MUST be doing something wrong..? Overall: 1)The easier starting alone is worth every penny and effort! 2)The "new" power is honestly a disappointment. I already own a DR650(PUKE!!) and don't need a clone... My WR (WZ?) is actually a little better than that (what isn't?), if only because it is 100 lbs lighter.: My WR now reminds me of my old XL500 power-and-suspension-wise...(It was cheaper, lower, and street-legal too!) Suggestions?
