1976 RUPP Nitro 340 – Custom Black Widow Edition

What was your intended objective when you started the build?

My dad and I wanted to build a very custom sled that featured some out of the box ideas. The theme that tied our project together is Black Widow. In 1971 Rupp made a mini bike called the Black Widow. I am a Marvel fan, and the Black Widow movie premieres this year. All of this makes Black Widow the perfect theme for our custom hot rod sled.

What motivated you to start your project?

I have always wanted to do a custom hot rod restoration project with my dad. I grew up watching my dad and some family members building custom hot rods. This was the perfect opportunity to spend time with my dad and make a dream come true!

What was the most unique and creative thing you did to the sled?

The Black Widow custom sled stands out mostly due to our precise attention to details. A couple of our favorites include; lizard skin coolant hose wrap with gates heat shrink hose clamps, and painted motor and bumper with back-sanded contrasting aluminum fins.

What are you most proud of?

I am most proud of the priceless time I have spent with my dad bringing our custom hot rod sled vision to life.

What do other people say about your snowmobile?

Most comments on the sled are in regards to the attention to detail and custom touches that flow together to create our Black Widow theme.

    This “Black Widow” Rupp Nitro 340 is a masterpiece. Not only the Make and Model speaks for itself, but the custom detail that was done to it! From the exterior color scheme, nickname, detailing, custom parts and of course the hardwork and time spent into making this masterpiece. I highly recommend the custom detailing artists! Great work per usual!! 👏👏 🔥🔥🔥🔥

  • Jean Dallenbach says:

    Excellent!

  • Todd says:

    Amber and Myron did a fantastic job on this build. I have seen it in person and it is remarkable. I admire their vision and keeping a theme throughout the project.
    The best part of this build is not the sled but the time spent together as father and daughter.

  • Howard says:

    Tastefully done with just enough customization to make it pop. Still a Rupp at heart. Video is also well done. Nice work!

    (Man, what trouble I could have gotten into with this machine back in day.)

    • Amber VanBruggen says:

      Thank you for the sincere comment!

    • Myron says:

      Thank you so much for the comment. Yes, We had to keep the RUPP colors as the foundation of project. The Blackwidow theme was so much fun discussing and creating the vision. I would like to find a RUPP minibike and clone one into a Blackwidow. SO MUCH FUN!

    I was an owner of a 1976 Rupp Nitro-340 CC Machine!! Loved it and even road it to work 5 miles away to the Shell gas station I worked at. We had trails all over NE Ohio [Geneva, Ohio Area in Ashtabula County]. Road all over PA too!

  • Dave says:

    Love your restoration. Inspired me to pick up a 1976 340 nitro like yours. It’s literally a basket case. The carburetors have been messed with. I believe it’s got either the wrong carburetor bodies or the wrong slides. The slides are way undersize for the bore. Like 1/32 to 1/16”. The flat bottom of the slide faces the air cleaner side. Believe that’s backwards.

    The carbs are Mikuni 38s. I believe that’s correct. Could you confirm that. And any other jetting specs you have handy. Thanks, Dave

  • tim burrows says:

    i had a 1976 340 nitro back in the day served me well but my brothers 77 rupp 440 nitro would move does your 340 move as well looks great wish i still had it

  • That Old Guy says:

    That makes this old racer smile. This Nitro 250/340/440 series served as a wake up call to Arctic Cat. Arctic assembled these under contract using Rupps parts and Cats clutches. Rupp was in rough financial shape by this time but eager to keep going with hot sleds. These spanked the old
    school 1976 El Tigre 500 FAs. Without this model making waves, Arctic might never have released the LC 6000 440 El Tigre’s for 1978.
