Like I said, it's not likely you're going to notice any difference between +4 and +7.

 

If you're racing competitive shit, then run it at +7.

 

If you're just dicking around run it at +4.

I noticed a considerable difference in timing changes from +4 to +7 on my old motor. Stock cylinder, 5 mil crank, 66 mil bores on VP C12. Duncan 403 Eliminator motor.

 

I will be finding out later this summer how the differences feel on my 5 mil Redline Serval.

 

I will be curious on your feed back once yours is up and running.

Why stAy with the 5 mill just curious?

1: I already had that crank from my previous build, which was a billet unit from Crank Works.

 

2: My understanding is 5 mil is the max you can go before having to trench the cases.

 

3: I felt 5 mil would be just right for my riding applications.

I don't know if you finished it or not, but Cam setup my 7 mill duner at +5, on 110. If it where me, I'd start at 5, and then move upto 6, then 7.  And see if you can tell a difference. My worthless .02
