Axle keyway

Wondering if anyone has any expierence with this type of keyway hole for the inboard sprocket. All the other keyways are normal and as far as I can tell, there isn’t a special keyway for that size hole.

Honestly looks like they did pilot holes and skipped going to the full leg size… Get the drill out.


That’s what I was thinking but I wasn’t sure. Appreciate it.

What do you think the quality control is like for the REST of the manufacturing process if they can do that?

I’m sure Parolin’s QC is fine given they build thousands of karts and parts each year.


I’m actually on a Sodi this year but same point still applies :joy:

That’s a little bit of an overreaction don’t you think? You know what they say about people in glass houses… Nobody is immune to mistakes. If it becomes commonplace then that’s another matter.
