Shift drum mod

[202mphbusa]

Years ago after my first trip to Maxton
Where I had a 5-6 miss shift on spray
That winter on motor year down and
inspection I did A gearbox swap thru someone who offered a exchange setup
He also offered what he called a nitrous shift drum mod
This shift drum has been in my bike since like 2002.
Without making me sit with a Jack and Diet and re analyze the gearbox.
Is this doing anything? Or I was ripped.

The question is . . did the mod actually produce a result that you were looking for?

I assume the extra depth is to hold the pin on the fork in place?
It looks like 30 seconds with a drill.

Who knows. So long ago
I have had two 5-6 miss shifts at Loring in the 100 or so passes. .

Extra depth would not hold. The tip of the fork ball should not touch
I think that is what they were trying to avoid.
Maybe under load shift shaft deflects that way. Then the tip rubs ?

Hi. I asked Robinson's about it. He said no need to do it. Every thing has been done to my trans that he said that I needed. Low 1st OD 5th 6th.
