What is the best roller chain tensioner for # 25 chain

[MoRo1212]

Hello motored bicycle members,

I was wondering if there is anyone that have used "universal chain tensioners" for # 25 chain
that are spring-loaded???

I would like any links for these universal (or custom/fabricated) chain tensioners that would work with Curry electric motors ,and any comments about the home-brewed/fabricated variety of vchain tensioners out there in these subforums!!

Thanks in advance for any/all replies!!

btw ,I have noticed while reading some of the threads posted regarding chain tensioners that Baja Motorsports DB30 mini bikes have an adaptable chain tensioner, but when i checked the links for this,I could ONLY find the replacement idler wheel for the chain tensioner-hopefully I get a few updated links in the replies!!
