Re: Finishing First Build - Leftover Parts??
I recognize 6, 13, maybe 11 and 10.
6 are bolts that would go to your sprocket clamp. Maybe he had extra, did you put a bolt through every hole in the clamp?
13 is a gas tank filter from the chinese valve/petcock. Something to be thrown away and replaced with a better one in my opinion. Anyway, as long as your gas tank was clean of debris before hand and you have an INLINE fuel filter then that piece isn't very important.
11 I think is the spring that is part of the clutch mechanism. Have you gotten to ride your bike yet?
10 must have been part of a large downtube adapter. Not important if you didn't need it. It's typically only mountain bikes that have the large downtube.
