cheapcycleparts and others used to list the old number (and it's replacement) on their parts diagrams for the older bikes, but now they just show the newer part. Was wondering what year they made the change as I'd like to get a used one and need to know when the change was made.
Hey fc, I read somewhere the model year that the shift shaft was upgraded.
I remember it because it was the same model year as my bike, a 1991.
So, anyone with a 1991 model or later should have the heavier shaft. (~8 mm diameter compared to the earlier ~5 mm shaft)
I don't understand why they broke. If that is the original rod, it appears to be the same size as the external shift linkage rods on many bikes I have owned, including my former Ninja 500, and my Honda Rebel 250, and my Yamaha XT225. I especially like dirt bikes that have an external rod linkage, because if you drop the bike on the left side and it hits the shifter, it will just bend the shifter, not force the actual shift shaft back inside the engine, requiring a complete engine teardown to repair.
I stand corrected. I misread the post, and I know about the difference between the shift shaft, and shift rod. I can see the shift shaft being replaced w/o splitting the cases. Guess I need to get my old man glasses.
I agree Jerry. The fact that the rods break is a weak point in the system.
The only reason I can see them breaking is the fact there is a beefy shift shaft that goes to a smaller shift rod, and if the linkage is sticky, a rider will most likely push harder on it to get it to downshift, and snap the rod. IMO
I know that several riders have had issues with the bike getting stuck either in gear, or neutral, and myself would probably smack the shifter with my size 12 boot, hence breaking the rod.
