KCvale
In memory of KCvale 1959 - 2019
Well, I have been told that I do not communicate well, so I have already purchased the parts I listed earlier.
These are the pics of what I have, I just need to find some 13 gage spokes and a seat.
(sigh) I find 16g or even 18g spokes as long as you have 36 of them to be fine, using thicker spokes to me is a lot like using #41 drive chain, which in essence is like using ship anchor chain for your dingy row boat anchor, over kill to the max.
You have an internal 8, cool, but for for most people a 3 is great' but like you some need a bit more gearing flexibility for the terrain.
If you need more range sure, I recently finished an HS144 53cc with a NuVinci hub with an infinity variable rear hub, and have a 5-speed SA hub build in the bay right now.
Fortunately you bought a good engine in the HS 142HS-1G tapered shaft clutch attached engine, it's the gasbike POS transfer case that will screw you.
The very first thing (in my opinion) you need is to buy yourself a 4-G belt transfer case.
About $140 here.

Start with that and you should have a bike that you actually spend more time riding than fixing bud ;-}
