420 chain?

[Mike Cyanide]

Eber since my motors started really pulling I've noticed the chains aren't so tough. Seems like I hafta tighten or do something about em every couple days to s week. Lol what do I do here? 420 chain? Is it just me?! What's the deal,

A 420 won't fit. Unless maybe you can make a spacer and a longer bucking bar that will allow the thicker chain

I dug this up. https://motoredbikes.com/threads/420-chain-for-66cc-bike.55676/
Also, if you are willing to pay and wait, RDManu has some extended clutch shafts, offset sprockets, and other items listed that may help.

Get better chains. RK Racing HRU 415HD Chain is rated for 250cc and 60hp 2 strokes and is built for race bikes and quads. DID 415 ERZ chain also falls into that category. If your bike's can ruin those chains, then the chains aren't the issue, something else is going on.
