Throttle Body - ZR-1 Net Registry Forums

A1990 · 10-13-2009

There has been some recent discussion on the factory use of DAG on our throttle bodies to seal the blades against the bores. My question is when we have our throttle bodies bored to 63mm, what happens to the DAG? Is it removed? Replaced?

Also, speaking of throttle bodies, I have seen some sell that are now 65mm. There has been a lot of talk about not even needing to bore them to 63mm on a stock displacement engine and now we have 65mm.

Just looking for your thoughts on both these topics.
