On my ‘78 w/40mm Bings; Choke - I just break loose the top locknut at the boss on the carburetor cap. Then, spin the bottom locknut completely off a...

What I like about anaerobic sealants is that you are not “under the gun” to get things assembled and torqued. I dislike being rushed because time is t...

My final drive output seal (78 R100RS) started leaking last fall and spitting oil onto the rear wheel. That was my first trip into that thing! I did ...

My understanding is that our Bing CV carbs are actually quite good at compensating for changes in elevation without modification. Both the carb nee...
