I checked 15 Rupps and found that the Cherry wide strap levers are 6-1/8" Narrow strap levers are 6-1/4". Kind of odd ???

Hi Joe51, I have many original Rupps with the original Cherry brake levers made in Japan. They all measure 6-1/4" in length.

Saw this on Craigslist https://minneapolis.craigslist.org/ank/snw/d/stacy-1971-rupp-blackwidow/7075377314.html

I have some NOS, I will include NOS conelok nuts. http://blackwidowmotorsports.net/_15178_lower_rear_shock_bolts.html

JB Weld works good too.

Flanged bearings are for low speed use. Snap ringed bearings are generally high speed precision bearings. With that said the quality of any bearing is the buyers responsibility.

Aftermarket kill switch. Rupp used a smaller all chrome switch in 1969 and 1970.

You can replace the rear struts with shocks. You can also install a jackshaft with sprockets, just flip the rear wheel so sprocket is on the right hand side of bike. You will need to spend some time aligning the sprockets on the jackshaft to match the drive clutch and then the rear wheel...

If your chain has a loose or tight spot or is bent, it is time to replace your chain. Rupp did offer a chain tensioner for the Bandit, so you are already on the right track with your added tensioner.

It would not have a two speed as I now see it has the 60 tooth sprocket. It would be a XL-500 or XL-350. They use a jackshaft with 2 sprockets on it. Here is a link to the 1968 Rupp parts catalog: http://blackwidowmotorsports.net/1968_rupp_minibike_part___catalog.html

It's either a TT-500, XL-500 or XL-350. Since it does not have the original engine there is no way to tell.

Hi Bob, Have another B/W serial number to add to the list. 1 204073

Washer should be on the other side of the swing arm by the shock, not against the bolt head,

Brown wire is brake light
