At age 68 I impulse bought a Baja mini. It sat for months but once I saw your videos I started tinkering,,,Im up from 19 to 38.7 MPH and having a ball. Friends & family think Im nuts but I feel like Im back in 5th grade!! Keep on posting,,,your videos are the best!!
I'm 74 and back in 1950's our 3 HP Briggs&Stratton minibike did 35 and 4 HP did 45... so these speeds seem low for 6 1/2 - 11 HP... Last minibike in 1968 had 350cc 2 cylinder 2 cycle 4 gears motorcycle engine...
@@BuzzLOLOL We used to run 3.5 Briggs back in the 1980's . It used to take forever to get to 35 MPH with a 3.5 horse.. The bikes these days get to top speed in a couple of seconds. Makes it more fun in my opinion.
@@Black66 - Our minibikes were light, home brewed from electrical conduit. We had a minibike with 2 1/2 HP Tecumseh engine and a jackshaft for hill climbing power. It would go about 32 but was twisting 8,000+ RPMs... we had trouble keeping connecting rods in that engine... it was stock but seemed cammed up higher than the Briggs... torque was kind of flat until it got up to about 3,000 RPMs... The 350cc minibike was really quick... throttle wheelies in first couple gears... and there's something about the stereo sound of dual exhausts on a minibike, one high muffler on each side... scrambler style for ground clearance... and the sensation of unlimited power...
I'm , 30 and got out my old go kart from when I was a kid I got in 1998 when I was 6 it's a full size single bench seat go kart it's called fun power brush and Stratton motor in it 8 hp motor I took original motor off cause it's mint condition and worth lots of money this cart is with all original parts decals on floor board ect so I bought the 670cc v twin 22hp motor for it custom made rear bolt on plates for motor added about 200 lbs of lead weight blocks from my stack I use on asphalt circle track racecars for adding weight in places to be legal and get weights right on scales. Well this cart rios at 89 mph and handles like a dream it's all red with roll cage black leather original seat cover in perfect shape and yellow roll bar padding cart cane with anyone else has same kart or knows what I'm talking bout let me know they worth money in stock non restored mint condition
I have the exact same engine on my Mini bike. I let My girlfriend's Grandson ride it and I told him before he left "Do NOT Snap the throttle on this thing because if you do it will launch you in a 90° angle." What does he do? He snaps the throttle on it and lands on his a55 and scuffs himself up a little bit and breaks a couple of things on the Mini Bike. It's still ridable, but it's just the irritation of what happened and the fact that he didn't listen to me. But anyway, life goes on.
Better be careful running them with stock flywheel I had one sling a magnet off and it wasn't even turning hi RPM and it almost came thru cover if high RPM it will go thru and there's your Leg .....
Thanks for the video, I like the vintage look on that minibike absolutely my favorite out all of the bikes on your fleet. Can’t wait see what it does with heavier valve springs, I also heard it float at high revs.
Do you know the difference between the speed karts flywheel and arc flywheel? The fins are different shapes, just curious if it makes any kind of difference on anything. Thanks
The channel is about testing different combos . The results will vary from combo to combo and from bike to bike. It is fun finding out the results. Check out the playlist for more bikes and combos. Thanks for watching!
I wonder how tall a gear the Ghost would have pulled with it's stock ignition? It reached the limiter pretty quick, it's probably got more top speed in it.
Look a mini bike ! Wow i went out and got a new one from my local bicycle store when I was 12 years old. No suspension only one break with that little lawn mower engine. I remember it well. Then a couple of years later when I outgrew it I sold it to a friend and purchased my first Honda 400 Hawk. As the years progressed as I became more confident in my driving ability I increased to 750 class and so on. I honestly don't understand what the purpose owning a mini bike even if it goes 200 miles an hour. Once you reach a certain age. You can't go on the highway with it, it's not a dirt bike, it's extremely Limited to where you can drive it. You can't get a license for it, you can't get it insured. I don't know call me crazy.
We can register minibikes in AZ . Many are street legal here. I have. Video coming soon on registering a minibike . They are much less expensive than motorcycles and are just as much fun. It's also fun being able to work on them and modify them myself unlike many motorcycles. Also most of the community of people around the minibike and kart hobby are very nice people.
I'm reading the commentary and the majority of people here exactly in my age group. Basically reminiscing about when they had one. I still don't see the point of getting one as an adult when there was so many other options.
Hi I'm Ricky from Bloomsburg pa I have a azusa minibike with a 212 hey what size are the ape handlebars and the measurements for your seat as soon as I saw how yours looked I had to have one thank you so much
@@Black66 since you enjoy doing comparisons. I have one for you. Try opening the gap between to coil and the flywheel to .060 and record any differences. I’ve been running my at maximum gap with no ignition problems.

I was getting Valve float around 7k rpm with 12 tooth clutch and a 75 tooth rear I swapped my rear to a 70 tooth and I was getting Valve float around 6k rpm I changed my valve springs from 22# to 26# and am still getting Valve float at 6k rpm. If I run it without a load tire off the ground it will pull well above 8k rpm . Am I misunderstanding gear ratio and load ?
I remember as a kid growing up a friend's Dad built a centrifugal clutch system on his mini bike to where it utilized 2 centrifugal clutches and the one on the engine was geared lower than the clutch at the jackshaft and once the RPM was topped out the higher geared clutch at the jackshaft would engage and the mini bike would come up on a wheelie and it was pretty fun to ride. It was a mechanical 2 speed automatic transmission and i just thought about it now. What if you replaced that 4 Horsepower engine with one of these Ghost engines. That would be awesome and you could market it. I remember older guys would ride my friends mini bike and when it went into 2nd gear and the Front end came up. They would crash it and the seat would come off and we would all start laughing. Good Times
I had a mini bike I took a engine off of a cement mixer an old cast iron Robin engine, very old, with a large Tire in the back and gearing I was able to get that thing to 70 mph. Very scary
Its been a long time but I do remember mentioning what clutch I was using at the time in the Ghost videos because I was comparing the Ghost to The Predator 212.
I gear the bikes this way for the testing to get the engines into the max RPM range. This is how I tell when they are valve train limited . Thanks for watching. Check out the playlist for more combos.

Check out the Ghost playlist for many more Ghost videos and part combos with over-torqued flywheels. I can not believe all the over-torqued flywheels that have come off after 300+ videos! 😅😁😄 Thanks for watching!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ONJbFaEecQM.html
It's awesome to see you still have the best fun on the minibikes i have a little fat tyre and i will get it going with the V2 big block hope it will work
In my opinion the Tilly is a better buy because it is less expensive in the first place. The extra money can go towards mods. But either way they both are fun and that's what counts.
Check out the Ghost playlist. I have had many different gear ratios and part comparisons on the Ghost. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ONJbFaEecQM.html
No, the clutch will work either way. check out the Ghost playlist for many combos with this bike. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ONJbFaEecQM.html
@black66 - I have a MB200 Coleman and I am running a 212 Ghost Go power sports 26mm Mikuni Go Power sports torque converter w/ juggernaut/10T 420 chain My question is, what sprocket should I run on the rear tire to gain more top speed? Also if I buy a stage 2 ghost performance kit what do you think would be best to run it at?
I’m having trouble with my ghost I replaced the ignition coil on my 212cc ghost gapped it just perfect and now it kick back like crazy threw on the original ghost coil back on and didn’t have that problem at the moment I’m still running stock fly wheel
Check out the Ghost playlist. I have tried that carb and many more. Also jetting in one area is usually not the same in another area even if the bike runs the exact same engine because of elevation differences, temperature humidity, etc. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ONJbFaEecQM.html
Its governor is in the coil. Install a stock coil on the Ghost and a bullet flywheel....you will fly!!! Add a Juggernaut and a pulse pump and just hang on!!$"
Wow, This takes me back to growing up in the suburbs of Detroit, mi. I had a rutman minibike. I currently have a mini bike from farm and fleet engine is to small going to change it out to a predator hemi.
Sir I have a question I hope you can help me with it. I just got my Coleman B200 and my front wheel wobble. “ very bad” I need advice on where can I get an aluminum wheels. I saw some of your videos where your other mini bike has aluminum wheels on it. Where to buy them? Thanks and have a great day!
@@Black66 absolutely! I've been wanting to mod my mini bike, but I wasn't too sure on how small engines operated oppose to regular car/truck engines. But I found your channel and you make everything look so easy. Thank you agian for making this channel. It's freaking awesome 👍
I think your gonna have to move the sticker a little more counter clockwise, deff save you on your speed. just saying 😁😁 love the bike hope your brakes are as good as the scare chairs
Really cool video and nice to see how the upgrades worked. The two things that I would try to improve acceleration would be tighten up the clutch so it revs higher at takeoff and try to use a smaller rear sprocket to get the top speed. I would also love to see what difference a good carburetor would make like a nice Keihin. Maybe a cheap wideband to tune it in or old school just read the plug ;)
Thanks! I'm always messing with different combos. Have you checked out the other bikes on the channel? Here is one of them. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xV8i59aGUao.html
excellent content! enjoy watching your videos! im also local to K-town. would you have an extra ct100 rear wheel to sell? i am needing one for one of my dirt bug projects! cheers!
I was wondering if you put heavier valve spring in any of your builds. Just put a mikuni carb and header pipe on a Coleman ct200 and at higher speeds the valves sound like they are lifting. But yours don’t seem to do that
I bet yours rips with that kit! Check out the ghost playlist. We have tried many different heads, carbs gearing etc on the ghost . Thanks for watching! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ONJbFaEecQM.html
I don't know if I should just do a governor delet on the regular 212 or get the ghost, probably just get the regular 212 and pull the governor valve out would be the cheaper method and then adding aftermarket flywheel and parts.
It's funny how much misinformation there is on this engine that keeps getting repeated by folks that have not pulled one apart. Some differences are minor, some are not. At the least you'll want to do head, cam, carb and springs to match. I don't care either way whether people buy it, like it or not, or if it's better or worse than anything else. Here's the facts on it's specs: The Ghost has: Ducar (Hemi) head 22lb springs Valves: 24.5mm (stainless) x 27mm (steel) combo. Standard for a hemi head, slightly larger than non hemi heads. Different cam profile. Digital ignition, 6200RPM limit Different (Iron) flywheel to suit 22mm slide carb, branded "dekni" 5.5mm valve stems with 5.0mm keepers Oil filler on top Exhaust valve relief on piston crown
Idea, take what the ghost and accessories cost and put that cost into building a regular 212 and do a comparison on the two. For 500 bucks a mild built 212 should be in the 14/16hp range.
@Elijah Scott LeFever don't know how is more like it. I have never seen anyone say let me spend X amount to go slower than if I would have built one for the same amount. To each there own.
GoPowerSports has a Universal Minibike Suspension Kit, Complete Front Fork Assembly that might go on there. www.gopowersports.com/minibike-suspension-kit-complete-front-fork-assembly-universal/
