- Is a Predator Ghost faster with valve shims?
Installed a set of valve shims in the Predator Ghost-powered Azusa minibike to see if it would gain any RPM.

Isn't it nice to know that just shimming your valves and giving them that extra little bit of seat pressure helps with high RPM valve train stability & increased mph
Valuable information as always. Thank you. You might also enjoy getting and building 2 and 4 stroke bicycle kits. The 2 strokes are generally 66 cc. The 4s are 49 cc. Buy cheap bicycles at Walmart. Kent beach cruiser and blue Kent bike. Are great platforms. I’ve built 6 so far.
Great video , bike is rolling !!
Thanks Black66, yet another great video. I love they way you show the step by step process and don't take a lot of time doing it! Can't wait to see what's next. 😘👋👋💯
Dude, killer as always.
I always enjoy watching your videos.
Glad you like them!
Great channel guy ..great information 👍
Thanks 👍
I absolutely love the videos!!You certainly know alot about mini bikes. Do you sell any of these mini bikes/parts??
Thanks! Ya, I do from time to time.
Black 66, i see a new pink mini bike in the background 🤫 😄
That new pink bike is going to be a rocket ship!
@@Black66 sweet cant wait👍
Nice gloves man!! 🇺🇸🇺🇸🇺🇸
This guy with a sweet minibike gave them to me! 😀
If your removing the valves or anything in the head on a ghost 212 be extra careful removing the bolt that holds the rocker arm pins. Mine took out the threads removing it and when I put it back together I didn’t realize it was bad and on the first start up I had a pin slide out and drop the whole rocker arm. Pay extra attention there.
Check out the ghost playlist. Added valve shims heads cams and other parts to the ghost .
Good job that thing will haul a66 now

Hey 66 where did you get those shims? Great content found you looking for ghost vids.
Thanks! I picked these up from the hardware store in town.
I kinda like the ghost 212 racer
It's like preloading the shocks for a different ride...I like all the testing, but the 0 to 30, in my opinion does not give the motor time to react when the power band just kicks in about 30mph...?...If you test at 40mph just after the power kicks in, then I think the numbers would be different...Top Speed seems to give the final in performance gains...
When’s the Minibike jump? 😉
Are these just washers? If so what are the specs
Black 66 I’m having problems with my mikuni, I have a grehua vm22 mikuni in a Coleman kt196cc go kart and I can’t seem to tune it right I have tried everything even watched the vid about air leaks and still it runs lean and only runs in choke I opened it up but everything seemed fine can i get any recommendations about what to do with it?
clever tool but how about a close up of it. 👍🏻
Can you take a look at the ANBULL 223CC from Amazon or if you have any experience with the engine
41 on stock cc100x tranna port the head and could i shim the springs
Hey brother I'm knew to the mini bike life. What gasket do i use for the valve cover gasket? On the ghost engine? Any Info would be greatly appreciated! 😊thanks
could u do this to predator 224?
For those that may not understand, these ARE NOT Valve Shims, they are Valve SPRING Shims.
I have always heard them called , valve shim, or valve spring shim or hat. One of the three. In the automotive community I always heard "hat" more . Weird how things get their names over the years. Thanks for watching the videos! Check out the playlists.
@@Black66 Well, you're shimming the Valve Spring, not the Valve. Make sense? Valve Shims are like changing that Hat that goes on top of the Valve, ya know, the one that's just under the Rocker, on top of the Valve Stem? Not too confusing, I hope. lol
I understand how the shims work and all, but I cringe thinking about distance. How much distance are the springs at max rpm? After the mod how much distance is left? When I set my valve lash my springs are collapsed almost all the way. I just would love to know those two measurements.
I have an RB200 with ghost, nibbi carb, and exhaust. I am topping out at 36 mph and it sounds like I am at the rev limiter at like 85% throttle. What would be the best options to get past this? My end goal is to be in the 45-50 mph top end speed with best accel possible
I would say do what I did in this video. It will get rid of the rev limiter and add some safety at the same time. th-cam.com/video/lm6zTvhJHSk/w-d-xo.html
Can you do Ported head vs non- ported head?
Do you have a video on your fuel tank set up I have a mini bike I've been trying to figure out a clean way to mount a fuel cell like you have in the v of my frame. Also I'm interested where you purchased that tank I'd appreciate it.

Did you decide if you like the new Harbor Freight Ghost 212 or the Tilly 212 better? And where did you get those valve shims?
Picked up the shims from the local hardware store. Both are fun for what I'm doing.
212 tilly only bro
Where you get the shims
💗🌟
saludos desde puerto rico , me gustaria que armes un honda gx200
I 2nd this!
Yeah but it seems like the engine doesn’t like it, more like your pushing it more passed it capabilities, even if you do, do you think it could run to 9000rpms if it worthy or should you get a gearbox for it
Hey hey black.does your ghost engine have the stock rod still?wondering if a mild cam is ok with stock rod.
Yes, it still has a atock rod with a billet flywheel and a 252 cam .
If you haven't already check out the Ghost playlist .
I got a stock 212 ghost should I do this
So I had a head bolt break at old 17 ft lbs, been scared to torque stuff down on a predator since 😭
same shit happened to me but on the side cover bolts... TWICE, ordered a helicoil kit. and since then i climb the torque always instead of putting the necessary ft lbs immediately
The 212 ghost is hemi? What flywheel would it take, the hemi or non-hemi flywheel? Appreciate the info
The link is in the description for the billet flywheel
Are the shims for the ghost different then the regular 212 head? Trying to figure out what shims I need to order and don’t see any for hemi heads specifically.
Did you ever find any?
@@kevingonzalez1092 no, the hunt season came along and I stopped tinkering with the bike. Used it to help haul the elk I shot back to camp 🏕️ though!
🏍🏍🏍🏍🏍🤠
Not much on this engine yet.. I watch all ur vids.. good stuff..
If I remember correctly..u said they the stock springs might be 26 lbs .. I have coil and flywheel.. and max out at 6500 rpm guessing valve float.. but with a 26lbs springs... Why would they be any valve float... Most stage kits with cam only come with 22 lbs springs
I love to get pass 8k ... With rod and cam of course.. just trying to learn these little guys
The Ghost has a heavy valve train. The push rods are longer than a stock Predator and the rocker's arms are heavy. The engine could use a good set of chrome moly pushrods and some lighter rockers. I think with these upgrades the 26 lb springs would control the valve train better.
10.5 tires.. 55.60 mph.. 4.0 gear ratio? Spinning 7100 rpm with stock rod ? I need to know! How much rpm can a stock rod take ?
We will find out .
@@Black66 You be safe trying to break these engines!
Hey bro I did the exact same thing and now my motor is giving me hard kick backs and don’t wanna start got any advice for me
Check flywheel key for damage. Recheck your valve lash.
Where can I get some of those shims for my ghost?
GPS has valve shims
What is the fuel sir gasoline or diesel 🙋🙋🤗❤️🇵🇭✌️
Gasoline. Thanks for watching the videos !
Why 3 the lash adjustment why not 4
3 is in spec
Did you R & R the Rev LimiTeR? ™°H°∆°R°D™
Here is the video adding a billet flywheel and getting rid of the rev limiter. Check out the Ghost playlist for many videos with the Ghost th-cam.com/video/lm6zTvhJHSk/w-d-xo.html
Thanks Black 66 enjoy ur videos. Sincerely °H°∆°R°D™ FLaTLanDs oF KaNSaS
what tires do you use??
Check out the playlist. There are many different bikes on the channel with different tires. On some bikes, I use the ultimate street tire, some have Carlisle slicks, etc. It really depends on the bike.
I can do 55
Fast bike! Check out the Ghost Max speed video and the Ghost playlist for many combos with the Ghost.
