Does anybody still have the write up on this mod? Also has anybody done it and is it any good for my track bike. The carbs will be set up.

I don't think that messing around with non standard filters is a good idea.

The carbs need significant set up changes, and you'll always get a flatspot between the transition from needle to main jet if you don't modify the carb air jets.

It's not worth the trouble just to get probably 0.5 more hp.

There is no HRC filter mod - the HRC set-up doesn't use a filter. Are you referring to replacing the guts of the standard filter with aftermarket, re-usuable foam?
