Quadster if I go with the 87 jug I was gonna get one o ringed and hopefully find a vf2 reed cage and reeds. The power valve is in my 88 jug though so its really gonna depend in the condition of the sleeve and head once I get it all apart this weekend. If it needs a ton if machine work done (plus I'm already planning on o ringing it and getting the squish fixed) then I will be putting on an 87 jug. Any performance advantage to the larger reed 87 jug?
