What a great uncle you are. You are sharing your knowledge and building confidence in your nephew. I can see a lot of youths, like your nephew, watching your video and being encourage to try this themselves; "It is easy, and you can do it." is all they need to hear. You are very direct and clear in your explanations, which is critical; and you never talk down to your audience, even when talking about the most simple of mechanical concepts. A commendable job.

It's crazy how there is an air filter, but it needs spray to filter dirt. Ironic but makes sense because the spray is sticky and will sure catch those little particles. By the way awesome video I just traded my 250 dirt bike for a Murray full suspension dune buggy type go kart and it already had the stage 1 upgrades! I think it has a different piston too. Have a good one😁

Cliff P if your sure the tap and bolt are correct you could use it, I would prefer (if possible) to just clean it by running a bolt in and out with some penetrating lube to avoid the chance of crosscuting the treads with an aggressive tap As for mods you can buy a stage one kit or make your own what you need to do is remove the governer gear and arm make 1" diameter exhaust about 350mm long expanding to 1.25-1.5" 100mm-150mm long at the tip, drill the carb main jet to 0.8mm and add a high flow air filter and adapter (these are reasonably priced) this will give you a decent power increase I would also add additional crankcase ventilation and filtration system

Overhead cam, giant intake and exhaust ports, high-lift cam and a big-bore short-stroke with a hefty con-rod! It is built like a Honda XR engine! If you want, I can share some pics! I plan to get 15+ HP out of this reliably! Also, Super-lightweight.

The ones on the mini bike I'm restoring are rusted out where it had holes in it.
