just purchased a tmec 200. came out of the box mostly assembled only had to put together the front end.
problem is chain is resting on the frame on the back end.....
in this pic you can clearly see where the chain sits on the frame and then angles down toward the rear sprocket
tried to take it for a ride but after on a few miles chain started to eat into the frame as you can see (i am holding up the chain off of the frame on the back side so you can see the samage)
in this picture you can see the chain on the lower chain roller but also on the frame right after the roller
more pics showing chain sitting on frame
