rupp sprint specs??

[KNUCKLEBANGER]

I just picked up a 69 rupp sprint that had the rear wheel sprocket changed and the stock exhaust is missing. I want to know what the stock exhaust was and what size was the stock rear sprocket?

sprocket is 72 tooth for a sprint. the muff according to the brochure looks like one of these:

does anybody know if the muffler has one big hole in the end or 7 little holes like the ones in the picture above? Also, the brochure shows it with the larger 5.30/4.50-6 tires made by General instead of the rupp branded 14x6 tires. Did they come both ways?

I have only every seen them with the trail tires. It should have the mult hole muffler like what Markus posted.

Here is some old pictures of someone's Sprint from back in the day.

Thanks jmbmini, The old photos and the brochure pics were a great help. I actually already have that double elbow fitting that goes between the muffler and the motor, so all I need is a stock muffler to make it correct.

Thanks, I have already started to clean it up and it is coming out better than I expected.

Nice bike knucklebanger! Keep it original as possible! You don't see too many of that model in that condition.

Thanks!! I agree, they are only original once. I am only carefully cleaning it without changing anything. I am adding a nos muffler and returning the stock rear sprocket (that came with it) to the rear wheel. It has a rupp 14x6 front tire and a 14x6 rupp TRIALS tire on the rear. Some of my digging around on the internet leads me to believe that some of them came stock with two different tires, am I correct about this?

What is the other Rupp you got hiding behind it in the picture?

If you have not cleaned the chrome yet. Use #0000 super fine steelwool and "Not a SOS Pad" like most people do and end up destroying the chrome finish. After you clean it with the #0000 steelwool use a good chrome cleaner and polish it out.
