big gun rev box

Hello new friends long time drz rider 13,700 miles and running strong. I'm starting to do some performance mods. I have a slip on fmf and the jet kit is on it's way I have to adjust for higher elavation. Is the rev box worth it and what about the air box mod?

no ... the rev box is not worth it

yes ... give the motor fuel and air to suit your elevation

you could raise the compression ratio and refresh the cylinder head , do the loctite fixes and fit the MCCT . check the cam chain for wear

Do a search on ProComm

You will find they make your bike unrideable. Total waste of money.

Thanks for the help
