Am i better off using carbs that already have a throttle postion sensor? im going to be using megajolt, or do i need to fit a different one for the megajolt?

Craig.

I would make life a whole lot simpler doing it this way yes and having had to make up a bracket to fit a TPS onto a set of Weber carbs i'd take the easy route even if the bike carbs are a bit dearer!!

Yep, my ZX9 carbs came with a TPS and work the Megajolt no problem.
