I recently completed a modified sprocket cover for my '84 VF500F. The modified cover is part of a continuing series of projects (some large & some small) for this bike. The goal for this project was to re-work a stock cover to allow access to the front sprocket. For those of you who own a 500, having to remove the hydraulic clutch and then wrestle off the cover is a bit of a bummer when you want to inspect or do a quick change out on the front sprocket. To simplify things I decided to cut away the material the conceals the front sprocket while still keeping to the general lines and intent of the original design. As a first step, I wanted get an idea of the look of the cover with the material removed. To help with this I marked out the 'discard' area using blue painter's tape: Once I had the right profile dialed in I packaged up the cover and sent it to my friend Rick Denoon (DSP) for a bit of machining work. Rick custom built his own CNC milling machine and makes light work out of these types of modifications: After machining, the cover was media blasted and painted gloss black: Being a fan of socket cap screws I decided to replace the OEM fasteners and ordered replacements, in stainless steel, from Bolt Depot. I also purchased a set of NOS gaskets, two are required, from David Silver Spares: As many already know, when using stainless steel fasteners in aluminum casings, a very important step in the installation process is to use a high quality copper based anti-seize. The copper in the anti-seize compound helps to prevent a galvanic reaction between the two dissimilar metals: With anti-seize liberally applied onto the threads of the fasteners the cover was secured in place. The install of the hydraulic clutch is next on the list: With the socket cap screws torqued down and the clutch installed all that is left is a few test pulls on the clutch lever, and everything is looking good. Here are a few photos of the completed install: Side view: Plenty of room to access the front sprocket: I hope this helps other owners who have not been a fan of the effort it takes to access the front sprocket on the VF500F. Keep on wrenching!
