MULL ENGINEERING BILLET SHIFT STAR NOW AVAILABLE!

Yes, our detent will help find neutral by rolling up on the neutral spot smoother without any catchy rotation as typical with the stock roller. It also has a much wider contact surface with the star to better respond to the contour and stops of the star. HOWEVER, neutral on a 1D-5UP sequential trans is a double edged sword. Typically if they find neutral better, they also like to find neutral during riding too. We try hard to split those lines but finding neutral while in a race situation is a much worse deal for most. We have a lot of racers on pavement that run 1st gear starts in which neutral can be a big problem.

 

We have made recent refinements to our neutral stop to improve this without causing accidental neutral stops.

I really need to determine which flavor is most needed. From our current design, we would provide basically factory geometry, with our extended pins, and no neutral stop. This should be the desired profile for any neutral down configuration IIRC.

I replied to your PM. There are a few things to check. Make sure star seats properly against the shift drum and check the spacer that is under the return spring on the shift shaft. They can wear shorter and cause the shift claw to run closer to the star than normal.

I ordered mine not long ago and I finally got some aggressive time on it. There is definitely a noticeable difference in the way it shifts. I did have a stock modded star and I noticed that it has a more positive engagement feel and it also makes finding neutral a snap to find. Mine is on a WCR pro mod tranny and also accompanied by a fast shaft and shift pro arm and spring. No missed shifts and I tried for one in choppy switch backs.
