kz750 e/h jetting

i just got my dyno jet kit for my kz750e/h carbs. it wants me to drill out the slidelift hole. do i drill both slide lift hole(s) since mine seem to havetwo holes? i hope thats not a stupid question. thanks guys!

i have dyno jet kit 2102 and my carbs are a set of keihins

I did. Pretty sure the instructions say holes?

The holes would be on the engine vacuum side, and not where the needle goes in. I don't have there kit, but would say if there is more than one hole on the engine side of the slide, and the kit instruction says "Holes", then drilling both would sound correct. Give them a phone call to verify before drilling to verify, before drilling incorrectly.

I just read their instructions. The picture shows two holes in the slides. One is in the center where the needle goes. The other one already exists to the side of the needle. Use the drill bit DD# 31 to ENLARGE the existing one on the side of the needle, do not make a new hole.
For informational purposes only, this allows the slides to lift faster.

any issues? sounds like you dont have any problems. i surely dont plan to drill any extra holes. im having an issue with my choke return spring, it just seems to weak to return close. :evil:

I have pods from Z1, a MAC4-1 and I went stage 3 with the Dynojet kit and I'm pretty happy. I didn't notice a difference between the 130 and 136 jet but I'm having a problem with either a fuel cut or ignition after 6000rpm. It was present before pods and jetting so don't be leery. I should have fixed it before doing either but I'm impatient and chasing an ignition or voltage problem is time consuming.

You will need to sync the cards with either gauges or the home made method. It ran good with just a bench sync but it runs awesome with the legit sync.
