Help! My head is spinning from the plethora of available kits!

I just had that problem with my PK-80 kit
I measured the brake hub with a cheap 4"
brass caliper, about $3-$5 at a hardware store
or on fleabay.
Anyway, it measured just under 1 7/8",
so I traced it out on the sprocket and trimmed
it out with a die grinder and a 1/4" rotary file.
I would suggest as a cheaper alternative (since most folks dont
have a $200 die grinder). Get a hole saw of proper size and the
necessary arbor. screw the sprocket onto a piece of wood, find the center
by using the bolt holes. start the pilot bit into the wood and be sure that you
get a straight bite when cutting into the metal.
It should go pretty quick, you can oil the hole saw blade and it will cut better
without burning the metal. If you decide to change sprockets, you already have the tooling to complete the job.

A little work with a grinder or really go at it with a dremel and you can make the sprocket center hole large enought to clear your drum...it may not end up being the prettiest, but it will work.

So you think it would still attach to the spokes with the rag coupler, even with the larger hole being ground in it?

If so, then that would make an easy solution, even if it isn't the prettiest.

Yeah, should work fine.

I enlarged my hole with a 3/8 drill and a metal rasp from the home depot. Like joe said it weren't dressed for the prom but it worked okay.
