I'm restoring a 1995 R.E. 500. I purchased the 535 big bore kit. I had planned on upgrading my vm28 carb to the specs listed in the Hitchcock's catalog (page 18, 117.5 main jet, P0 needle jet, 27.5 pilot jet). Several message board posts here recommended Bell's four-stroke performance tuning book. In the carburation chapter, he has a table titled "Recommended slide-type Mikuni carburettor sizes". The table has a "cylinder displacement (cc)" column. In the 500-650 cc row, his recommended carburettor size is 36 mm. should I upgrade as planned or buy a larger carb?
