That is exactly the one I put on mine. I was very happy with the pump, it made a huge difference in my startup. I haven't yet had the opportunity to get my bike in the 60's or 70's yet to see how it does... I guess I need too so I can see how it acts at higher speeds.

I am assuming that you have replaced the vacuum lines? A new strong pump like that might be collapsing weak vac lines.
