Setting your ring gap is pretty dang crucial. Use the table under the Ring Gap wiki here:(https://www.mopedarmy.com/wiki/Ring_gap)
& when I mentioned wrist pin clips I meant these bad boys (https://www.treatland.tv/12mm-malossi-wrist-pin-clips-p/malossi-wrist-pin-clips-12mm.htm). Some people say to NEVER reuse them even if only in for a little bit but you can test your luck- just inspect them to make sure they’re not too compressed or warped. There’s some good threads that tell you which kinds are best/proper installation to avoid over compressing them and therefore decreasing the tension holding them in place. One thing for sure is to MAKE SURE the protruding piece of metal is PARALLEL with piston movement (exactly directly towards or away from the head). If they’re not they risk getting compressed during high RPMs and ejecting, going on a destructive rampage inside your cylinder, ruining your new kit.
A temperature gauge (https://www.treatland.tv/trail-tech-digital-TEMPerature-gauge-in-BLACK-p/trail-tech-742-et3.htm , for example) let’s you know that you’re going to seize, before you seize. Anything above 400F is considered the danger zone and if you have this it'll give you enough time to stop running your bike, let it cool down, and avoid engine destruction. A lot of people consider them mandatory when running a kit. This is especially true if you’re new to kits and are experimenting with jetting.
