Just got this What is it?

[scrapper]

I got this for the grandkids need any info as to what will fit,brand? I am only wanting a good running mini bike. I'm not sure what motor will work. Handle bars are 7/8" and front axle is 5/8". I dont see any way to adjust the chain. I'm guessing its old? Tires only say 4.00-6 on the back and the front is smaller. Any idea what will fit? Thanks for the add.

Thanks, I will do a search. I think I was going cross eyed. Do you know what size/ type wheel bearings? What tires fit it?

I see why I didnt find my model do remember looking at them though. Does this look like the 300X?

It’s a Cat Slingshot, model R3502

from what I noticed mine has a foot brake and no brake hub on the rear wheel. The 3502 had a rear brake. I ordered new wheel bearings , a brake lever in case I can add a rear brake, and a throttle with about a 32" cable. I'm going to need tires but can't find the front tire by the size 4.00-6. The front tire was I think a 4.10/3.50-6 I think that is wrong number but it's smaller than the back. I was thinking about a harbor freight engine. 99.00.

the reproduction 14x6 "trials" tire made by coker has will be the most equivalent to the rear 4.00x6, the front on those were smaller from the factory, the tires on your roller are the OG ones. the scrub brake has been added by someone over the years since the orginal disc brake has been removed for some reason

Thank you guys for the help. It would work to take a board and cut it flat add some foam and cover it for a seat?Did they have numbers on them for an id? Is it possible to get a generic rear brake and why is there 2 gears bolted together on the rear tire?

Here is a picture of the 2 gears bolted together. I have seen several different types of axles the front one is still ok looking but the rear isnt very good shape with out filing the threads on one end. Looks bent and rusted bad.

The serial # is located on the leading edge of the engine plate, left side if your sitting on it. Paint usually fills in the serial # stamp, so sometimes you need to lightly sand/wire brush off the paint to see the serial #. You can always make your own seat, but I’d recommend using carpet padding glued together for better support. A single piece of foam usually doesn’t work well and it can be a rough ride due to bottoming out on the board while riding. Or buy a seat off of eBay. Get a band break setup/kit. It’s easy to install and set up. Lastly, the double sprocket in the back is not supposed to be like that, it should be a single sprocket. Hope this helps

ok I was going to try some heavy foam, I will look around.

ok I started on the mini bike. Got the sanding down started. The number on the frame is 7008625. Is there a place that tells you what it means?

It’s a 1970 model. First two #’s identify the year.

Do the rest of the numbers mean anything?

The rest of the # is the production #

Front tire is a 4.10/3.50-6 and rear should be the 4.00-6. Both were knobby tires from the factory on the Slingshot. Similar to the set up on my sons 400TS (pic attached)

I wanted them to be the same diameter so that's why I changed it.

Its vintage and neat keep it looking correct. Find a 5hp Briggs or Tecumseh. ...will be neat bike when finished we love the lower fork spring.

With the rake of the factory length fork, putting a 4.10/3.50-6 on the back will make the back of the bike sit lower. It will create a reverse rake making it look squatty in the rear.

Looks close to what is on it? I will double check.

I found a picture of a guy selling a slingshot 350. It looks just like mine only better. I'm confused is a 3502 close or what? The set up of the rear brake is the same as the 350.
