As I have posted before you can shorten the advance curve for dual plug
conversions by layering shrink tubing over the weight stops. One layer will
shorten the curve 2 crankshaft degrees. My experience so far is use two
layers for dual plugged 336 cammed bikes and 3-4 layers for 308 cammed bikes
(1000cc). 800s require less retarding so about 1 layer less in each instance
will probably work. If you are going to move the point of maximum advance up
the RPM scale you can lighten the weights. Pry off the small "E"
rings to remove the weights. I drilled mine with 1/4" hole about 2/3 up
from the pivot along with a 1/8" hole as close to the first hole
without breaking through. This changed the full advance RPM from 3000 to
3500 RPM. Stronger springs would be a more elegant approach here but haven't
found a source for these yet.
トリガユニットのホール素子が壊れた場合には、内部の部品だけを交換する方法がある様です。

Switch part #2AV54 でも、構造的に、ダイナ等のピックアップを付けてもOKだと思われます。
