Sprockets Bolt size for the standard kit rear sprocket

[layboomo]

Hi can anybody tell me the size and length of the rear sprocket bolts in the standard 80cc kit. I want to use upgraded hardware there and I'd like to get it before my kit arrives. Thanks......it's from motorizedbikeparts.com if that matters.

My Grubee and old raw/PK kits use 6 mm bolts that are 1 3/4" long on
the threaded section
they are the same thread as the engine mounting studs, etc

they are a little long and could be as short as 1 1/2" and still get 2 nuts on the inside
and you know that 2 nuts are always better than one

You can use 1/4" of course which are a hair larger and would be easier to find
25.4 mm = One Inch

Get some sexy button head allen bolts to dress it up a bit!

I used 1/4" stainless with nylock nuts they worked really well. And like Forbisher said 1 3/4" long.

I've just replaced all the boring nuts on the drive sprocket with domed brass nuts...
Hmmm...
