Mikuni VM33 assemblies were originally sold for racing  applications or big-bore modified street engines. These carburetors  offer the ultimate in top end horsepower and provide all the fuel your  motor can use when under extreme loads. These carburetors also need  tuning for each application in almost every case. We totally  disassemble, clean ultrasonically and then by hand and replace any part  that needs to be replaced. After reassembly, setting the float levels  and bench synchronization , we jet the carbs for our stock test bike  using pod air filters and aftermarket, baffled exhaust and road test. We  verify the operation of the carburetors in a road test. You can either  start with our baseline jetting or we will rejet these carburetors at no  additional charge to your specifications. Our baseline jetting is #130  main jets, #30 pilot jets, 6DJ30-4 jet needle, 261 0-6 needle jet, .6  air jet.
