Motor was completely disassembled and put back together by shawn at proformance prototype after I purchased it used.
I have +10 swinger
110 race gas
New drive line clutch , no lockout
I do not know what needles are in it, I do not know how to tell .
I did a glug chop last night with 168 mains, to me it looks lean but I am going to have shawn look at it this weekend.
