|There is a part referred
to as a "roller" that is part of the synch mechanism. It is a donut shaped
piece of metal about 3/4" in diameter. If you know where to look and what
to look for, you can see it rise and fall, from the right side of the
bike, as you twist the throttle. [Engine not running]. |
When this part loses diameter from wear the synch screw will not work, even when screwed in to the limit. The amount the roller needs to lose is too small to detect without some micro type measuring.
You cannot get a replacement.
There are two things that you can do; either will result in more synch room:
1. replace the synch screw with a longer one.
2. snip the spring on the synch screw to about 1/2 it's normal size.
If i remember correctly there are two springs on the screw. You have to snip the correct one, which i believe would be the one at the head rather than the one at the point. It is easy to determine once you know how the mechanism works.
