I have had my 00 zr500 carb for two years now. Right away when i bought it i added vforce2 reeds, black magic reed block spacers, and a 1.375 stiffpaddle track and a 55-51 helix. I also ran a Black Magic Monoblock head with pumpfuel inserts last winter. I wasn't to impressed with the head I only noticed a slight increase in lowend power and a headache with finding premium gas. So this winter I'm considering adding a DD single pipe, possibly K&N pods (I'm sick of messing with the airbox for jet changes) and for sure adding and EGT if i add the pipe. Any suggestions for addons or setups would be appreciated.
