Whoa Hoss!!!
Don't get to cranking that thing around too much, it shouldn't take more
than a quarter turn either way to true things up. What the adjuster does
is that it gets the shift pawls to click into a pair of actuating
grooves on the shift drum, and hence makes it ready for the next shift.
No clicky mean no shifty, at least not in one direction.
I just went through this with my bike today. Reassembled the trans the
day before yesterday and couldn't get the thing to shift beyond second
gear. I called Mark, who referred me to a guy named John, who told me I
had the shift pawls misaligned. I managed to get that straightened out
by removing the shift lever mechanism and rotating the pawls about 60
degrees. (Five minute job, trans out of bike.) I put the shift lever
back on and voila', third gear. There were still problems with the
upshift, however, which I remedied via the adjuster.
Here is a suggestion. Put the bike on the center stand, pull in the
clutch and shift the trans into first and then second gear (or third to
second if the problem is with the downshift) while rotating the rear
wheel. Release the clutch (or tie it down temporarily with a cable tie).
Slowly turn the adjuster in one direction and listen for a faint
"click". The click will be the pawls latching into the grooves on the
shift drum which means that the trans is now ready for a shift in either
direction. Go slow and easy. On mine it only took about 5 degrees of
rotation to make a difference. Now it seems to shift nearly every time
in either direction.
One other thing......look in the back of the service manual for the
transmission (4 speed) assembly photos. Note the position of the shift
pawl mechanism. Put the bike in 2nd gear and remove the shift lever and
its housing. You should see the left shift pawl partially visible at
about the 10 o'clock position. If it is not there it means that you
rotated somthing while you had things apart. Take a screwdriver and
rotate the pawl carrier via the cog on the end so that the left pawl is
at the 10 o'clock spot. (Listen for the click) Reassemble the shift
lever housing and try again.
Oh, yet another thought! Make sure your linkage isn't binding and
preventing the shift lever from returning to its "neutral" position. If
it does the cog which turns the pawls will not allow them to return to
center which again means improper engagement. Check by shifting and then
slowly moving the linkage in the opposite direction while listening for
the magic click. BTW, you did get the new shift spring installed
correctly, i.e. with the ends of the spring on each side of both the pin
on the segmental gear AND the adjusting pin, didn't you?
