Howdy Gaga,; those tiny little chains are the toughest chains and the most expensive chains you're ever gonna get #25 H-da are the same material that timming chains for heliocopters are made!!! they don't like when timming chains for heliocopters streach or break, and thats why they make them out of the best stuff around. When ur chain is loose,tighten it up- can even remove links .
I have two brand new chains on stand by and and old used one that I use as a tool for removing sprockets.
Anyway, it's great to see some one else in this forum with an Island Hopper.
I've got the 35 & 48 cc rack mount chain drive Bridgestone Titans.
P.S. Greetings; welcome to the forum ...I love my Island Hopper
