Hey shadetree hope all is well. I watched the YouTube video again and I guess he was using gear oil to lubricant the chain since its in closed. Question what should I use to keep the chain lubricated ?
Thanks

gear oil works good, thick, sticks well. 80w-90 gear oil.

Factory chain should be o-ring style.  https://www.motosport.com/blog/o-ring-chain-vs-non-o-ring

Continuous oring chains was common on a lot of the older 3 wheelers. I've broke a lot of them in the past and they was usually replaced with the cheaper non oring chain. Either chain inwould use chain lube on it. A can will last a long time and most are formulated to not attract particles as bad (dirt). That chain case isn't really sealed. I've came across some filled with grease in the past as well. You want to talk about a mess to clean out.

Welcome to the forum ---- One thing I learned when running bikes with chains , is keep up on the adjustment  ---- don't know about your 125M , but some models will eat a hole in the crankcase if the chain is ridden loose ---- some models have after market case protectors available

I haven't done any work on the TRX125's I've picked up yet, but did some nosing around online doing research on them.  Looks like these used Oring chains, but most of the replacement chains are non-oring.
