Clicking noise in first and second gear in wot

[jatgm12]

So basically I noticed, especially with a lot of weight, upon acceleration really hard, with my new cg250 atv engine on my Bashan enforcer frame, their is a clicking banging noise. I thought it was the chain but I'm not sure. Are their any things I should look for that could cause this to happen other than the chain?

Valve adjustment?

I had a clicking noise on my Boom Vader bike even after tightening the chain. With a sprocket upgrade the chain was closer to the lower lip of the chain guard, https://mymotorcycleblog.com/grom-clone-chain-clicking-noise/ , I trimmed away some material and it went away.



Check for scratches/marks on your chain guard.
