As this decreases, the spring stack needs to decrease equally. This can change
due to the shoulder bolt ‘setting’ into the arbor (see C2)
If your effective shoulder length is off, or your shoes are
worn, adjust the height of your overall combined spring
stack accordingly (i.e. if your effective shoulder length is
0.5mm short of the 16.00 measurement, decrease the
overall combined spring stack height by 0.5mm, or if your
shoes are worn by 0.5 mm, increase the overall combined
spring stack height by 0.5mm).
Frequently asked questions
Q: When should the springs be replaced?
A: When the clutch ‘hit’ occurs too early or too late.
Q: Should the clutch springs be replaced if the shoes wiggle on the arbor?
A: Not if the clutch is ‘hitting’ correctly. Don’t mess with it
Q: What is the acceptable tolerance on any of the measurements?
A: For the most part that does not matter. Suffice it to say that any efforts
to make the three shoes behave identically will make the best performing
clutch. Taking extra time to balance the three stacks (shims, springs,
bolts, etc…) to as close to the same length as you are willing to put effort
into will result in a better performing motorcycle.
Q: One of my two riders weighs 85 pounds and the other weighs 45 pounds.
Should I have their clutches adjusted differently because of their weight?
A: No, there is one best setting and it works for light or heavy riders.
Q: If my clutch basket changes color, should I replace it?
A: If it is blue or purple, replace it. If it is silver or brown, you are fine.
Cobra is now going to greater lengths to ensure that the clutch on your
motorcycle is performing the best possible from the shop and so it may have a
different clutch stack or shim washer from what you are used to. Please take
measurements for knowledge sake but don’t blindly restack washers to different
heights without first consulting the factory.
Gearing
For a bike with a centrifugal
clutch, it’s better to be geared
too low than too high.
What happens with improper
gearing?
