Several years ago I purchased the cast throttle bodies from Z1 after they moved past the CNC models. I ordered the chrome version also for that extra HP, (j/k).
I know there were tons of issue with the early models, but what is the impression of the cast units? Are they worth installing, or not?
Any and all input appreciated.
