YFZ Jetting?

[freestylemxr]

What would you guys recommend for QRS slip on, no air box cover, I have a GYT-R Jet kit, thanks!

also just wondering but can you remove something from inside the QRS silencer? I jsut noticed there were allan bolds holding the end cap on so i was wondering if there was a silencer or spark arester you could take out for the track or something, thanks!

The QRS is a permanant core it cannot be removed, as far as the jetting i assume this is a yfz because you have the gytr kit. We didn't complete all the tests with the yfz yet so i don't have the best results yet.
