Re: Diablo Shop 503
Carbs on the Diablo are either Tillotson HR3A or HR14A. Other Tillotson carbs work as well as long as the linkages are set up properly. . DSC07109.JPG . I not going to go through the process to rebuild the carb on this post. I'll save that for another day and another post. But needless to say, the c...

Re: Diablo Shop 503
With the hood, handlebars, motor, dash and headlights installed, now you can tackle the wiring. If you need a wiring diagram, let me know and I can email you one. For restorations, I use all new color coded wires. - Brown is ground - Black is ignition for killing the motor - Yellow is lighting and w...

Re: Diablo Shop 503
The Voltage Rectifier is a simple AC to DC converter with a fuse inside. They are originally designed to be mounted with the terminals down but on a Diablo, they are mounted terminals up which creates an issue. When the snow get on them, it melts and leaks down into the body by way of the vent holes...

Re: Diablo Shop 503
Install your brake system. If the splines on the brake rotor are worn but still intact, you can use the rotor to failure. The brake rotor is softer than the shaft and is meant to be the "sacrificial lamb" of the two. Put the aluminum spacer on, the rotor and then the E clip. Clean the steel bushings...

Re: Diablo Shop 503
Cutting the holes in the nose cone is always a challenge. Put the nose cone in place. . DSC07090.JPG . I use a Dremel with a drywall style bit and follow the outline of the rectangle opening. Then drill through the nose cone with the 3/16" bit to add the two mounting holes. . DSC07093.JPG . Then ins...

Re: Diablo Shop 503
The headlights used on a 503 are a bucket style WIPAC light as opposed to the flush mount lights used on the 500 & 502. It also uses a trailer style lamp rather than a festoon style lamp like the 500 & 502. I like to sandblast and paint the housings keeping the socket and the ground tab free of pain...

Re: Diablo Shop 503
The motor goes in from the top and between the handlebars. I leave the top two rubber motor mount out to give me some room to move the motor around. Once the lower motor mount is in place over the three rubber motor mounts, then add in the top two motor mounts and bolt everything down. This is a goo...

Re: Diablo Shop 503
The original starter used on a Diablo is a Bosch 001 158 004. The "158" series starters are fairly common and the last three digits designate the nose cone which turns the starter in the desired position as needed. The 004 starter on the Diablo is meant to put the starter under the motor and keep th...

Re: Diablo Shop 503
The Diablo 503 motor is fairly unique being a Hirth 190R. The one thing that makes it unusual is the very small tapered output shaft measuring 24mm at the large end of the taper. The Hirth 54R motors in the Diablo 500 & 502 also have this small tapered output shaft. Common motors of the day had stan...
