My next r came with the 6.5 rollers it worked good for me untill the big bore kit.the spring is in the clutch,i'm running the white set and think 7g rollers worked best for me there.The #85 is a good start and getting the next 2 larger is wise.Where are your jets comeing from,I believe the keihin 7mm round are the proper ones we've had some problems finding them,the ones from provo are the 8mm,they can be tapped to fit.No doubt,you have a home here!
