1972 Rupp Scrambler

#1
Well, I never really intended to get into Rupps but when an opportunity knocks, I usually answer the door. Several weeks back a lot of two Rupps came up on my local CL. The first is a semi complete 1972 Rupp Scrambler and the other is a 1972 Rupp Roadster 2. My plan was to take the Scrambler from semi rough roller to rider for Windber. I began about a week ago so a lot is done but I wanted to post up the start and a couple pre assembly pictures just for fun anyway.

This is what I started with. The pictures supplied by the seller yielded a correct Rupp 4hp engine that had been blown apart with some key missing items (so I thought). After getting the engine off the Scrambler, I found the missing parts to the Roadster motor. I'll still have to find some donor items to rebuild the original engine for it but honestly, it's a great start. I know it's not correct for the Scrambler but I'm not building a show bike. I'm just doing an exercise in turning a project around like I've watched several do here. Thanks for the inspiration Karen! I get so wound up in making things perfect that I almost never get any of my projects done so I just wanted to build something from start to finish with a goal in mind. As for the Roadster 2, there was a good portion of that as well and I think I'm going to repeat the process later after I find a few of the missing pieces but build something along the lines of a Black Widow type bike.









So in actuality, this is where the project started.





The first thing I did was scrubbed up the front wheel parts. I had bought a pair of the vintage Carlisle tires that were one size larger than the factory. I like the more aggressive look for this bike. In the foreground is the rear fender after repairing. It had the usual split in the middle plus the tail was almost doubled back. I hammered everything out smooth and welded up the seam.



Next up were the small parts that I could fit in the blast cabinet including the triple trees and swing arm. I cleaned, prepped and painted them. Forks and legs after reassembly.



At present, I found a way to get the frame in my blast cabinet and do as much as I could with minimal maneuverability inside it. After which I did the rest by hand with my angle grinder. It is now prepped and painted. I've been working on this for between one and two weeks and it's looking good for my goal. I was going to reassemble the rear wheel last night but found that the previous owner had really messed up all the hardware so there is a trip to ACE after work today. The roller should be together by the weekend and hopefully a rider over the weekend so I can do my final tuning before Windber. More pictures posted tonight once I get things straightened up after the thrash so far.

Great start AJ and a nice find:thumbsup:
Thanks Owen, this is sort of new for me. I've always been more interested in restoration than rider quality bikes so doing this has been an exercise in finishing things. I needed something to help me focus on a single project and this has been really good for it. So much so that I never really took any time to take pictures of the individual items before I worked them. I think the effect will be had in the thread over the next couple of days as I add some pictures of the progress from here on out. One thing I did that wasn't intended was paint work. It was supposed to be a clean up and assembly but I just couldn't get past the rough paint. Anyway, thanks again for taking notice.

I have a feeling this is going to be a fun build to follow.
Thank you for the interest! I'm not sure how much fun it will be to follow though. I'm really trying to make it as short as possible. I will post some updates from here on out but it'll mostly be just finished stuff. Now what I do with it afterwards (which I haven't talked about) may get a bit more interesting but I haven't nailed those details down yet. I'll either work with this some more after Windber or it'll spill into the Roadster 2 build.

A little update from last evenings work on the bike. It appeared that a previous owner had assembled with incorrect hardware so after a trip to ACE I've not completed the rear wheel assembly. I'm going to replace a few parts to the hub assembly as they were a bit questionable but I feel they'll be ok for the short term. I couldn't get correct length hardware so I proceeded to measure and cut to length. It was necessary for the hub mounting but the rim parts didn't really need it, I'm just that way! :laugh:





Finally, the frame is painted and I'm giving it an extra day to cure. I don't want to be scuffing it to much at assembly so waiting an extra day allows me to fill in some tasks on other parts to the bike.



So back to it this evening on the shocks, rear fender, and anything else I have time for. I'm getting super anxious to start assembling this project though. It's getting harder to wait.

A late night last night yielded a roller finally. It's no trailer queen or show bike for that matter but I'm pretty happy with what the outcome has been so far. It's really coming out as a nice rider. There are a few items I'd like to replace at some point but it's all good for now.

Looking good AJ. I did a couple of quick builds recently. The Rupp Rat and the Bonanza Rat. Like you said, I spend so much time on a restoration that it never gets done.:laugh: I just wanted a couple of bikes to ride and not care about scratches. I will at least paint the Bonanza after Windber as I think I have all the mechanical stuff pretty good. I kinda ran out of time for now on the Rupp rat. I will work on the original engine when I get a chance but I may just put a predator on it for now. Your Rupp wasn't as rusty as mine.:laugh:

Thank Karen! It's been fun although cleaning rust at any stage isn't my favorite thing to do.

As of this evening, it's getting close. I Managed to find a new chain and brake lever in my parts stash, cha ching!
