The previous owner already rigged up a running light on the back. I could probably mount one of these in the faux gas tank. https://a.co/d/9p7kudX

You're referring to the flywheel from the Baja? I'm not sure. I guess for mini bikes, when you go aluminum, you just take the headlight off or get a battery and tender? I can't find any aluminum flywheels with magnets on the inside for a charging coil. Speaking of flywheels, that aluminum one...

So, my Baja has a headlight (swapped with LED) and I didn't originally consider that when I built this Predator. Can I simply steal the charging coil from the old motor or buy a new one? This is the aluminum flywheel I bought - https://a.co/d/048GCgJ. From what I'm reading, I just need to pull...

I prefer to just weld all the internals together, but I guess that would work.

I've officially encountered the hardest part of this build....reassembling the pull start recoil assembly. I can't tell you how many times it sprung back on me. I got it together a few times but the pull cord was limp (i.e. 6-12" inches that wouldn't retract on the coil assembly). After many...

I like that! Paint it with heat resistant paint and Dremel it. Even just flat a sand on the edges would look really good.

I decided to scuff up some parts while they're off the motor. Paint them as bright as possible with all the crazy colors I have left over from other projects. And add some clear. It's not exactly what I had in mind. Oh well, it's just a mini bike. Next time I'll use a different...

I decided to clean it up some on my break. The steel wool worked good but my Temu handheld steamer worked better. Next time, I'll use that to clean the inside as well. It's still a turd, just less dirty. It's mint if you squint.

I caught most of the savings with a shop vac and by adding towels inside the motor while I taped. Then I sprayed brake cleaner inside as I turned the shaft. It would puddle at the bottom of the engines with any shavings it caught and I would dump / wipe it out. I then started pouring a small...

Yea I know, lol. I almost did it, but decided against it. I just picture when it's all back together not being able to get it to crank or run right and that's one less thing to question when I'm troubleshooting. If this ends well, my next build will be bigger. Got the 18# springs in and set the...

No billet parts in my near future. At best, just cheap aluminum ones. Keep in mind, this is just my first real build. If this doesn't blow up, I'll go further on the next one. Cleaned some things up. My attempt at polishing the the exhaust port. I'm to wimpy to do any porting on this build.

Finally snuck out for a little shop therapy. I taped the side hole and used a 7/16x20 bolt. I tried putting 1/4x28 bolts in the governor holes but they felt too small. So I taped both of those holes for 5/16x28 bolts. I've squirted most of a can of brake cleaner in it to get the shavings out...

That's for the top 2 holes (1/4 x 28), right? What length do you use? Some builds I've seen look like the bolt is sticking pretty far into the engine. The sensor hole is a larger bolt, right? The last Red Beard video I saw, he threaded that hole but not the others.

Finally got it off. I punched the governor out and removed the oil sensor. This is how the guy sealed the hole where the governor went, lol.

Well, I hope Blaster works. I've heated it, beat on it, pried on it, and every combination of the 3. It's not budging.

Yea I have a map gas torch. I'll try heating it after work. If that doesn't work, I'll shoot a little blaster on it.

I tried that. And I hit it relatively hard with a heavy hammer, but it's not coming loose. I managed to knock the cam loose from the other side, lol. I think I have it back in right, and the cover is partially installed to help hold it in place. Can I hit it as hard as I can? Is there anything I...

Can I use spray to help remove this old flywheel? I've beat it with a hammer (on the bolt with the nut partially installed) as well as the sides and it's not budging. I know the valve grinding compound is required to seat the shaft to the new flywheel, but could I spray some blaster to help get...

Idk. I couldn't find good info online. I ordered both springs from eBay (seller = OMB Warehouse). I messaged them after getting the first set and this is what they responded:

Great info, thanks! I did read that some people set them to 003 but I wasn't sure why so I set them to factory. I'll change it when I install the new springs. I'll do some more research on valve lashing for this motor. I probably did it wrong. I just stuck a screw driver in the spark plug hole...
