Before balancing the customer’s bike, I need to check a few things while sourcing parts
Checking on the plan to go with a mysterious sidelink
It’s simple! Since the body is the same anyway, swapping “#3 and #1” should work
That’s what I thought, but #3 can become #1
#1 cannot become #3…
It’s a shaft issue
#3 has synchronized levers on both sides
These are necessary and not available as individual parts
“There are reverse-spec options for K through N”… but
A right sidelink would be nice
But a left sidelink would make the cable routing difficult, so I’m ruling it out.
This butterfly valve shaft
I’m worried about the risk of removing it.
It’s fixed with an M3 screw about 1.7 mm thick
And the back end of the screw is crimped to prevent it from coming out
Removing it as-is doesn’t feel great for the shaft’s threads
And when you remove it, it definitely gets a bit burry
If the threads strip, the screw size would have to go up, so that’s a no-go
There’s a risk of powder from grinding off the crimped side getting into the carburetor
This area is just held in with wool and not sealed
Unless there’s a serious problem, I’ll only inspect this from the outside
