Hey all,
Well - just when I hit 170 miles on my new 66cc HT engine, the chain tensioner decided to take a turn on me, my wheel, my spokes, my tire, and ultimately my bike.
Surely there must be a better design...
this kind of carnage i can deal with,its the broken casting behind the chain drive gear that bothers me.split case and take to work for aluminum welding.
i hope its weld-able.
sorry to see it happen to anybody.
next project will be spring loaded tensioner.i suspect needing to build at least 3 before i come up with something satisfactory.
well i put on my spare engine,stuck a roller skate wheel in the lathe and cut a chain groove into it,that stuff is tough,while turning it i made a ring like a rubber band,i couldnt break it.
mounted it in the bracket,lined up the chain and tagged it to the frame with my welder.
its NOT moving.
will spring load my other bike when i get casting welded and start my new build.
What you probably can't see from the picture is that the frame is also bent... Time for a new bike just because of a poor chain tensioner design.this kind of carnage i can deal with,its the broken casting behind the chain drive gear that bothers me.split case and take to work for aluminum welding.
i hope its weld-able.
