Azusa Chain Tensioner?

[ALRUI]

Hi Folks - Anyone have ideas for a chain tensioner for an Azusa mini? I was hoping for some kind of bolt on solution as I dont currently have access to a welder. Any input is appreciated!

Thanks

You would have to fab something to fit a round frame with this:

Or make your own:
You don't absolutely have to have a welder as this could be bent by hand and a clamp on mount made, but a welder would definitely make it easier!

Yeah, I'll have to figure something out. Looks like youre running that RLV chain? How do you like it?

Thanks!

this is what i made, been rolling for almost 3 years now. This is an older pic, i have a billet side cover and RLV gold on gold race chain now.

this is quite clever. I've been trying to come up with a way to add a tensioner without messing with the frame. could you post a few more pics of this set up and a list of parts???

thank you so much

most are just parts from the hardware section of tractor supply. the little sprocket came from OldMiniBikes i think. the crappiest part of this setup is the conduit strap that holds the adjustment nuts to the head, ive replaced that a couple times in a couple years, but ive found better ones since then.

this tensioner design had proved reliable for me over several years, in light of what the nay says said when i first did it, chain is virtually locked on as long as everything is in line.

you could easily spring load that, too.

did you have to tap the holes on the engine block?

 

[stargazer7467]

i did not have to tap any holes, and there was no reason to have a spring. I prefer a solid idler sprocket anyway.

Wow thats a cool idea... I like that.

Where abouts did you get that Idler sprocket from?

I believe Tractor Supply has those and OldMiniBikes should as well
