I just finished adjusting my valves. At the same time (violating a fundamental priniciple of science by changing more than one variable at time), I replaced my left crankcase cover that had been bent. Now the bike's back together and seems to run normally, but seems harder to start. It takes more to fire it up. The engine just sounds less smooth when cranking it, and it seems as though it's not quite timed right. I have the cams set up as per specs in the manual (TDC with notches aligned with the cylinder head surface). The valve clearances are within specs, too. (I've checked them several times after reshimming.) I did, at one point in the valve adjustment process, turn the crank the wrong way (clockwise) a slight bit (and noticed it felt funny--like it was slipping or something). I also installed a new left crankcase cover. (Thought it was good to do all the maintenance at one time, but....) In that process, I took the stator and pick up coil from the old crankcase cover and installed them in the new cover. That work seemed really straightforward and like there were no adjustments to be made. However, it seems like the rotor and pickup coil could have something to do with timing and hence, perhaps, the starting peculiarities. It starts, but with more cranking and more glug-glugging (very technical term, I know) than it had before the "repairs." I've taken the bike out for very brief spin and didn't notice any engine running or power problems. (1) Did spinning the rotor backwards mess somehting up? (2) Is there an adjustment within the rotor/pickup coil assembly that I missed? (3) Is something else the culprit? (4) Should I just stop pretending to be a mechanic and shell out some cash for someone who really is one to deal with it? --- '06 WR450 with all free mods, including grey wire pulled.
