I installed the Barnett MT-58 Springs (Black , 55 lbs @22.3mm). She pulled like a scalded ape right through to 7K.
Hope that does it for issues as I am tired of being a mechanic. Time to ride.
So for anybody installing the Barnett friction plates, spring pressure plate and retaining the stock drive plates I would recommend the aforementioned springs. Adds a little bit more lever tension is all.
If I had it all to do over I proly would have went ahead and purchased the Barnet drives plates as well as they may be a skosh thicker than stock.
