1980 110 What size bolt for muffler?

[1985BigRed250ES]

What size is the bolt that goes through the muffler and holds it in the frame? I will be parinting the muffler this weekend and need to know the bolt size as it didnt have one in it when taken apart. Also the bolts that hold the rear sprocket on the hub, what size are those? mine are missing the smaller threads where the chain cover bolts on. thanks.:TrikesOwn

well, the most common sizes across your entire bike are
M6x1.0
M8x1.25
M10x1.50

M) being Metric, the no. being the mm size and the 1.0,1.25,& 1.50 are the thread pitch. You will need to determine the length of the bolt.

My 80 110 takes the M8x1.25 and is about 2inches long.

Hope this helps you, it should if you go to the hardware store or something like that. Cheers!

the bolt that I am referring to goes in the frame on one side, goes throught the hole in the muffler and then the bolt goes through the nut welded on the opposite side of the frame.
