FAQ

Q1:Can I make my minibike street legal? First and foremost a minibike is the worst possible street riding experience rigid frame, air cooled engine, and no transmission. Its not cheap to convert a minibike to street legal machine. The idea of having transportation under a $1000 isn't feasible. You would be better buying a honda grom. Still interested? First check your state laws some states outright ban converting off road vehicles. You will need to add head light, tail light, brake light, turn signals, horn and and mirrors. And a custom charging system to power all this. Next you will probably need it inspected by your state police to be issued a title. No minibikes have a title.

Q2: Can I remove my governor without replacing the connecting rod and a flywheel? I don't recommend doing this on minibikes if your flywheel lets go your leg is right next to it. The flywheel can go through the blower housing. The more times you stress metal beyond its limits the more likely it is to fail.

Dangerous Knock-off Billet!

Be very careful when buying fake ARC billet parts. The fake billet parts or “knock-offs” were found to be machined, cast aluminum. You’re not getting billet at all, and this is especially dangerous if you were to buy a knock-off flywheel. These fake parts can be sold on amazon, ebay, and other websites with deceitful listings.

First minibike, gonna be ice fishing rig

TLDR, low end torque and pulling mods for towing ice fishing equipment?

Just picked up this little baja dirt bug 100 for free from a former foster family. I used to ride this thing around their yard as a little kid. It's sat in their garage for at least 17 years. I plan to make it into ice fishing transportation to tow my jet sled out and set up on the lake in the winter. The steering bearings are blown out so that's my first order of business. I'm thinking a predator 212 swap and welding on a hitch that's level with the rear axle. I've done some reading about pulling with these and people seem to recommend the CVT transmissions for that. I'm not concerned with top speed really. If I could get 30-35 out of it that's likely faster than I'll ever need to travel, but I'm about 260 and I'll be towing a sled loaded with stuff/maybe another person. The tires will be studded also.

How would you build this if you were in my boat?

No idea how but I got it running, but now it turns off whenever I accelerate. Help.

I’ve rejected the carb to a 0.038, Dont know what else it could be. Could it be because of the gas tank breather, it doesent seem to work the best.

f275 cam bog, coil bind?

hi! I recently built a 224 with 28lb springs from ebay meant to fit stock pockets; a fire 275 dyno cam and billet rod/flywheel with a vm22 carb. in the video it may sound like a carb issue however i am somewhat familiar with them have tried a 115.125 and 135 main jet it seemed to have no change in the bog past 3k rpm… not enough spring pressure? just conflicted as i’ve heard of people breaking in cams with 10lb springs and 26lb springs being used with say a 308 cam or bigger. Any help is appreciate motor or carb related

How do I get these bolts off?

I tried clamping them down but they won’t budge, the whole screw starts spinning and I’m scared if I clamp it down more I’ll break the tread or the bolt. What do I do, should I just order new ones?

Anybody have a stage 2 performance kit for 212/224 from gopowersports?

After recently blowing a hole in my block because I was cheap and didn’t put a bill of rod in, I’m starting from scratch and building it right. Was wondering if anyone here has bought the performance kit from gopowersports.

Turbo charging/super charging

I’m planning on making a REALLY fast build using either a 420cc power fist clone engine or a 700cc V-twin clone engine and I was wondering if there was anyway I could super/turbo charge either engine. I did some research but most builds aren’t done properly or use giant turbos that won’t spin. I plan to use a VZ21 turbo as it’s the smallest I can find.
