As I work to reduce my inventory over the next few years, there are unique parts and some other things that are not listed on my typical Parts List that I am now letting go. Some of these parts are one of a kind that have been hidden away in my private inventory. Some are just some good parts that were not listed on my Parts Page. Some may have nothing to do with Hus Skis or Diablos.
Email me at bruce@gogodiablo.com if you want any items listed below. All prices are in USD.

I have this Bolens Clock for sale. The upper left corner was broken off and I did a fair job of glueing it back on. The clock gave up and just won’t run anymore but the clock mechanism can be replaced as it is a typical clock with a AA battery. $40
Item 17 is a rebuilt gearbox for a Model 500. The aluminum has been bead cleaned and clear coated. Covers have been powder coated. Bearings, seal and gasket are new. Complete with new drive sprockets. $695 with the return of two sprocket cores. Would consider a trade-in gearbox if you looking to swap gearboxes.
Item 15 is a rebuilt gearbox for a Model 502 or 503. The aluminum has been bead cleaned and clear coated. Covers have been powder coated. Bearings, seal and gasket are new. The lower shaft and chain are new as well. $495
Item 14 is a rebuilt gearbox for a Model 502 or 503. The aluminum has been bead cleaned and clear coated. Covers have been powder coated. Bearings, seal and gasket are new. $395
Item 11 – 54R motor for Diablo. Taken apart. Measured crank for runout and it was very good. Installed new crank bearings. Piston is a Hirth 3-ring twice over and cylinder had some minor scoring – cleaned both up and reused. Has original Bosch ignition coil and condenser. Replace points, plug wire, wire cap and spark plug. All new gaskets and seals. Ready to install. $625.
Item 12 – 54R motor for Diablo. Taken apart. Measured crank for runout and it was very good. Installed new crank bearings. Piston is a Hirth 3-ring once over and cylinder had some minor scoring – cleaned both up and reused. Has original Bosch ignition coil and condenser. Replace points, plug wire, wire cap and spark plug. All new gaskets and seals. Ready to install. $625.
Item 13 – 54R motor for Diablo. Taken apart. Measured crank for runout and it was very good. Installed new crank bearings. Piston is a standard size Hirth 3-ring and cylinder had some minor scoring – cleaned both up and reused. Has original Bosch ignition coil and condenser. Replace points, plug wire, wire cap and spark plug. All new gaskets and seals. Ready to install. $625.
Item 7 – New piston with used cylinder that has minor scoring. This is a 77mm piston and cylinder set. For our Hirth motors in Diablos, this is 0.120″ oversize which is quite big but will work. The cylinder has the large ports for higher HP. It will certainly add some kick to that compression. This is a standard size piston and cylinder for a Hirth 192R. $75.
Item 8 – Hirth Cylinder with a 77.5mm bore. Has some minor scoring. I believe this is too big for typical Hirth 54R / 190R / 191R motors, but can be used with Hirth 192R motors as a once over size bore. $10.
Item 1 – Brand new NOS (New Old Stock) magnet set and ignition plate with all brand new components for the electric start Diablo 503 Hirth 190R (all) or 191R motors (with ignition coil under flywheel). This will make your spark like new. $275.
An original canvas Diablo Rouge Cover Set as shown. Yes it is dirty – it was in a barn for over 50 years. Yes it has some rips, you would too if you sat in a barn for over 50 years. But it is cool as heck for the collector that wants something most do not have. $75.
Something for the very serious collector is the Technicolor 500 Loop to Loop Projector with 3 original films. These projectors were used at Bolens Dealerships and showed continuous promotional films of the Hus Skis and Diablos. One film is the Hus Ski, one film is of the prototype Diablo 500’s and the last film is of the Diablo 502’s. These are silent films but in color. All one of a kind and I have never seen another. $550
Item 4 – Bosch Starter 001 160 003. This turns the opposite direction, so it can’t be used on a motor in a Diablo but it must fit some snowmobile made in that early 70’s era. $15
Item 5 – New NOS Flywheel for the motors in the Diablo 500’s & 502’s. Hirth 53R, 54R & 55R. $60
Item 6 – New NOS Flywheel for the motors in the Diablo 503’s. Hirth 190R and 191R. $75
