Anyone know of a way to convert an R60/2 from Bings to Mikunis? Craig the Vechmeister nearly had a stroke when I brought it up. He says keep it original. Sure and that is why it now sports a 12v alternator. I' m lucky to get 40 mpg and that is not riding hard! I've heard of post '70 airheads converted from CV to Jap and it seems to be a vast improvement. Help!

"Vast improvement" is the phrase used by those that have them for sale.

If yours is running rich, the carbs aren't tuned properly and/or need some new parts.

If it's running correctly, your mileage is function of how hard you ride.

There's no magic.

You should get 45+ mpg from your /2.The Bings are quite easy to work on.Anytime you have mileage issues with your bike,the first thing to check are the floats.They are notorious for cracking,so much so I always carry a spare.Also check thst your ignition advance unit is moving properly.Mine stuck in the retarded position,causing poor mileage,not to mention overheating.

Many thanks to chris and whicks for their replies. I had a single Bing on a 350cc Horex single back in the fifties which was wonderful. My R60/2 is what the Brits call a "bitsa". Bitsa pieces from all over-66 engine, 68 frame,etc. Vech, down at Sturgis, MS, genius that he is, dicovered the carbs were mismatched with an old style top and a new style top. Changed that. Vech can start it with his hand but it is a hit-miss prop for me. I've gone into the carbs again, no float leaks but I'm not real sure about the level. I have gotten as much as 45 mpg which, in my ignorance, thought was pretty poor. My Kaw W650 (Triumph wannabe) gets 60-70 mpg when the road tests all said 40. I'm an easy rider. Hence, I though the mileage should be better than 40-45. Actually the W650 is a lot better handling but Axis Sally the beemer gets more looks and comments. But 40 mpg whacks me out! If I ever come across a Mikuni conversion that will fit I''ll have to try them. Thanks again for your feedback. :)
