Re: SHOULD i UPGRADE CHAIN
FWIW I got rid of the stock 410 chain that came with my GT-5 66cc. after seeing how twisted it was. Because I am running a 3" wide tire and chain clearance was an issue I tried the KMC 415HD that Pirate sells. Much better quality and still narrow enough to give me the needed clearance. Be sure to get the HD chain, it is a "roller" type and better than a standard bushing type bike chain. #41 is stronger and the best to use if you can however.
