Im looking for a tread about the chain case on the viper that was modified for more oil getting to the bushing or bearing. thanks

I have never heard of that mod. Only thing I have seen is oil holes added to top gear. Yamaha has 3 in the Sidewinder top gear now.

That’s probably the one, I saw something on it last year, now I can’t find the tread
