- Stock vs MLM sound and ride comparison.
There isn't much information on these bikes online and even less showing performance upgrades. As far as I know this is the only footage online for MLM pipe on a Chappy so enjoy! Bike is a 1977 Yamaha Chappy LB80 with the 2 speed and high/low transmission. MLM pipe installed with no problems. Great MLM quality as you'd expect. Top speed increased from 42 to 54mph and still pulling with just a new spark plug, pipe, and upjet. Stock gearing as well. Biggest increasing in power comes in the midrange!
