Awesome video i currently have a ghost and all the mods i have done to it is because of you👌🙏 thanks for always giving accurate info and taking your time to explain.
Add that spacer back in between the carb and the head and see if you see some more gains. I may just have to order one of these, seems like its money well spent and might help me get that gain I need to hit my goal of 60mph. Another great video, thanks again.
This is my Favorite youtube channel! Thanks for what you do! Got one of these and can't decide what motor to put it on. It's either going on my hemi with the wiseco piston/rod combo and mongoose272 or my hemi with the 58mm stroker kit and 265 cam that already has a 225rs head. Decisions Decisions. Thanks again for the channel and how you are so detailed.
You should do a test with the intake runner to see if you get a better 0-30 timer. A longer intake runner usually means you get better bottom end torque and that should give you a quicker start. See if you can port match it with the head and carb.
Port it well. RBG got 2 hp at full song with stock ported hemi head... and springs, rockers, .265? cam. dont go tooo wild with porting the area between the spring perch and the outer wall is thin 4mm? so if get too wild with porting will break thru. 2 part epoxy can fix that. no matter what it wont/cant flow more than the intake valve hole 25mm on 27mm intake valve head... minus 5mm valve stem... x .85 (85% MAX theoretical port flow), but a nice smoother bigger flow path is nice to have... at full song. jetting is important too. that was a nice plug. i wish he wud tell us what jet he has in that carb... at 3700 ft in desert hot hot hot dry air. your elevation/humidity may differ
I'd be curious seeing a comparison between the carb mounted directly like that and with the extended intake tube. I would imagine it affects you torque level quite a bit by removing the extension. Cool project brother.
So all of these bikes basically have the same engine stock for Coleman just different bodies frames like the EX,and CT 200 U and the BTX, and perform the same overall, unless you mes with the hp like engine swap basically?
Thank you for the info! I just ordered one for myself! I'm just wondering if you are running a shorter rod on this bottom end or stock length? I have a 212 hemi block and bottom end with a stock length rod and I'm wondering with this shred head if I need more head gasket than. 010 to get .040 piston to head clearance? I can't tell if the piston is at TDC in the video or not
Update info for those into this! I just put this head on my tilly 212 265 banzai cam, big header pipe, billet rod flywheel build. If you use champion X rockers you will need to clearance the valve cover otherwise when you bolt it down it will hold your valves open just enough to where it wont start lol. But i put my vm22 carb back on and it ran about the same as with the stock head and small header pipe. I then installed a nibbi 24mm and wow!!!! Whole different animal all the way from idle to god knows when it will stop revving hahahha!! Massive improvement, but it does need a bigger carb than a vm22 for the gains. And who knows maybe a 26mm or 28mm would make more? I live at an elevation of around 1000 feet and by the time i was dialed in i had a 130 main jet, stock 38 primary jet, and the needle adjusted almost all the way up to get the hesitation out of it. Feels like going from a small block to a bigblock for sure!! Anyways hope this helps folks out there.!
I just watched one of your predator motor swaps and I want to swap the original motor out of a Coleman ct100u and I’m curious what clutch you used for the predator 212 shaft
Hows it going boss. Just wanted to say i appreciate your fascinating content and that i might have passed you by and waved today by the kingman library. Wanted to give a shoutout but didnt want impeded on what you were doing. Anyways. Enjoy your day and keep the content rolling.
Hey how do you have the gas tank running? Did you drill holes in the fake tank and fit a smaller one inside it. That’s what I think I’m gonna do for my baja build coming soon
HI! They have a couple different versions of the head. You can use the one I used in the video with the steel valves and automotive style retainers or when you are ready to step it up they have the stainless steel valve version with the titanium retainers for the higher lift set ups.
I just got one of these bikes recently I’ve had a mikuni carb that i’m trying to throw on there and a pipe what else would you recommend putting on this bike
now... port the head ... some and try it again. not a massive hog out but something a normal person cld do with ebay grinder in an hour or 2. polish exhaust if want to. the bearded gentleman, Not Fidel, got 2 hp at full song with stock ported hemi head on his dyno at 7700 rpm; where he had JB weld failure from grinding the roof of the head too thin. the head is kinda thin tween the roof of the port and the well next to spring perch... the "well" tween spring perch and side casing of the head ~4mm? some fill that area with epoxy? the head would have to be CLEAN, CLEAN (Brake) cleaned (NEW?) head clean for the epoxy to hold. even new head probably has machining oil coating of it from drilling/tapping/milling of the head at factory... so ... brake cleaner to clean it out of machining oil before epoxy the "well" tween spring perch and outer wall of cyl head? nice vid we love to see them. keep em coming.
Been debating on a new head for my 212e... Think you just showed me what I need for a lil more out of my Tilly MM212 combo. Thanks for your time and info on this one! Think Im ready to do my first major mod on my Tillotson and for a decent price too! Which cam is your bike running here? ...did'nt hear you mention it.
port the stock head with $20 fleabay WEN grinder. much cheaper. RBG got 2 HP at full song, with stock hemi head with nice port job alone.... other mods were in place and tested alone. the 1.2 rockers only gave .5 HP... hardly worth it for $140. the 24MM flat slide was $140... it got some gains but again hardly worth the expense. fleabay has 24mm carb for $25 it comes with 2 main and 2 idle jets... if u can get the TIGHT TIGHT TIGHT fuel bowl screws off... i cld not get them off with Propane torch and oil ???? WOW THAT IS TOOOOO TIGHT, for the fuel bowl. even vise grips on the screws didnt budge them. the WOT power with 24mm flat slide vs 22mm round slide wasnt that much as i recall... certainly not worth $140.... to me.
My mikuni vm22 is leaking gas’s from the hose at the bottom and when i mange to get it started it will die when i give it gas any tips at all would be appreciated
WHAT IS PERFECT JETTING??? IN WHAT CARB? AT 3700FT? im at abt the same elevation on temp desert and my patience is.... so pls tell what size main and idle jet to be "Perfect jetting"?????? pls repond. shdve been stated.... i got perfect jetting AT 3700 ft with....xx Main Jet... and xx Idle Jet . thx
ported with fleabay WEN $20 grinder shd be plenty. RBG got 2 HP at full song just from port job. the ROAD TO HORSEPOWER vids are must study vids, write down the hp/torque gains... notice where the motor is pretty much done making USEABLe TORQUE ~4500... and REALISTIC HP....6789 RPMS??? 22# springs for 6789 RPMS... is plenty fast... and wickedly overstressing a $450 motor. $100 motor and $350 worth of parts is PLENTY OF MONEY TO PUT INTO A TOY. fresh oil 10-30 oil, good as any, wont be running mini bike (generally) below freezing, every 8 hours. shut off gas at end of days run and let carb run out of gas so gas wont leak thru carbs needle and seat, thin oil... ruin motor. oil cheap... motor not cheap. simple
Been holding out a long time on a head upgrade for my tilly 212e, watched this video twice! Five minutes later my wife came up to me asking what the $200 charge on the credit card from some gopowersports place or whatever was for??🤣 You got me again Black hahaha! Cant wait to bolt up the nibbi 24mm and big pipe on that thing and hear what that banzai 265 is really all about!! Thanks again for all the work you do for your vids!!
@@Black66 Hahahah! OMB warehouse has these big toob 1-1/8" header pipes for $40 so im going to ditch the skinny pipe and try one of those too! If anyting, itll sound mean lol!
@@Black66 from your gut feeling, while i have this tilly apart now for the umteenth time putting this head, 24 nibbi, pipe etc on this drag bike with a juggernaut and 4.9:1 gear?......would it be worth upgrading the banzai 265 with say a hot 265 or gps 285? Or would that soften it up too much downstairs? right now its a wheelie machine ripper but kind of dies off early. I feel like it would like the extra duration but i dunno?
@@johnsmith-zd5he I love both ! They have the best sounding idle! I would say the hot 265 is my favorite 265 cam just for the sound at ldle and overall performance. The 285 is awesome too. It's not as snappy as the hot right off idle but once it gets spinning just a little ,it pulls hard and has a wild sounding idle. Both have the fun factor so it's a hard choice lol
port the head with $20 fleabay wen grinder. the bearded gentleman got 2 hp at full song with nice head port.... but broke the roof of the head into the "well" next to spring perch. its ~4mm there. some fill that area after brake cleaning it of machining oil, with epoxy. JB weld didnt hold and it sucked oil/air thru the hole in roof of port so the test was over... at 17 HP? at full song with hemi head, 26#? springs 7700 rpms? he felt the HP graph was still going up, a little, at that speed but wondered how much was truly left... wickedly overstressing the little tiller engine. 22# springs for 6789 RPMS? plenty fast enough... they are cheap enough to get 2 sets 22/26 and see where they dont want to anymore . e bay digital tach hour meter $9. on setting 2
Awesome video i currently have a ghost and all the mods i have done to it is because of you👌🙏 thanks for always giving accurate info and taking your time to explain.
Thanks! Happy the videos helped you out!
Great Video! Everyone needs a Shred Head in their life.
ordering mine now...YOLO!
YO THERE IN HERE!!! I buy all of my minibike parts from you guys!!
Black66 got me into the mini bike hobby got 3 mini now cause of this dude. Learned everything from his videos. Thanks black66
Man let me tell u he shows signs of much examples
I know its alotta testing and tuning till you get that magic just right he taught me everything I know
me too, he made things simple clear for me to understand
Love your stuff
Thanks for watching!
Another great video! Let’s get this channel to 100k, he deserves it
Thanks!! Its getting there .
The Shredder head needs a bigger carb! Its designed for a PZ27 carb and outflows every other cast head except the EVO.
Would that work on a ducar hemi
@@SpACeCruizeR2o3 yeah. ducar is basically tillotson.
“And it’s always fun drilling stuff”. Your right man you are right
Nice video David! Im always ready to see what you do next!👍🇺🇸🎥

Yea I think there's more torque to be had with that spacer
Buy a 240rs. 15hp out of the box, with loads of torque.
Power wheelies and still goes 60.
Looks like a killer head for the price! Thanks for the comparison video👍
This is my Favorite youtube channel! Thanks for what you do!

Watching you here in Colorado, another great video !
Awesome! Thank you!
Great results for the modest price of the Shred head. Which one did you use, the steel valves or the stainless?
I used the steel option with the 26lb springs
Thanks for all the great content.
I'd be curious seeing a comparison between the carb mounted directly like that and with the extended intake tube. I would imagine it affects you torque level quite a bit by removing the extension. Cool project brother.
definitely need to get a bolt on head for the tillotson! either the shred head or a wc946
I would like to see one of those great videos of the shred head verse the 224 head
So all of these bikes basically have the same engine stock for Coleman just different bodies frames like the EX,and CT 200 U and the BTX, and perform the same overall, unless you mes with the hp like engine swap basically?

275 cam

I don’t know if you’ve done it, but how about doing a video before and after head port and polish.

Do you mind if I ask what speedometer app you are using? Apologies if you've covered it already, I'm new here but love your channel, thank you!
I use a Dragy performance meter for 0 to 30 and digiHUD app on the phone for top speed .
@@Black66 Thank you! I bought a pair of Coleman CT200U-EXs and you've got me started on performance mods. Those will come in handy!
@black66 you have made me love minibikes and im finally getting a coleman cc100x tomorrow
Awesome!
awesome another great video
Hey Black 66 what is the best Head in your opinion? wildcat? shred head? or any other one?
I really like the Shred head, especially for the cost. The Evolution head is also a good head but it cost more.
Great video !👍👍
Thanks!
Hey how do you have the gas tank running? Did you drill holes in the fake tank and fit a smaller one inside it. That’s what I think I’m gonna do for my baja build coming soon
What gearing did you have on this? What clutch were you using as well? Really curious.
That's cool. Is that head like a stage 3 4 or 5 part? Im not at that level yet but I wanna be.
Hello From Philadelphia
HI! They have a couple different versions of the head. You can use the one I used in the video with the steel valves and automotive style retainers or when you are ready to step it up they have the stainless steel valve version with the titanium retainers for the higher lift set ups.
@black66 we have a big outlaw race we are getting people signed up for. Racebikes, E-bikes, nitro, gears, anything under 500cc. You interested?
Maybe...can you email me?
@@Black66 what’s your email?
what was the jetting you used before and after the head change thanks
wow, is that a stock cam?
Where can I find the disc brake drum for 6” Astro rim?
Hello sir, I saw on Amazon that they sell electric start 212cc engine with shaft diameter 20 mm, does it fit the torque converter kit ?
I just got one of these bikes recently I’ve had a mikuni carb that i’m trying to throw on there and a pipe what else would you recommend putting on this bike
What size head gasket did you run on this?
Do i need to modify a 212 engine for using a 28mm carburetor?
You can use a 28mm with a 212 but a 24 or 26 will be closer to the optimum set up with a stock or mild 212
Okay you sold me dang it😂
You using rockets with this, that speed seems slow compared to what ive seen is that just your gearing?
Nice!
now... port the head ... some and try it again. not a massive hog out but something a normal person cld do with ebay grinder in an hour or 2. polish exhaust if want to.
the bearded gentleman, Not Fidel, got 2 hp at full song with stock ported hemi head on his dyno at 7700 rpm; where he had JB weld failure from grinding the roof of the head too thin.
the head is kinda thin tween the roof of the port and the well next to spring perch... the "well" tween spring perch and side casing of the head ~4mm? some fill that area with epoxy?
the head would have to be CLEAN, CLEAN (Brake) cleaned (NEW?) head clean for the epoxy to hold. even new head probably has machining oil coating of it from drilling/tapping/milling of the head at factory... so ... brake cleaner to clean it out of machining oil before epoxy the "well" tween spring perch and outer wall of cyl head? nice vid we love to see them. keep em coming.
Where did you get the pipe from????
Made the pipe from an existing pipe. Check out the CT200U-EX playlist.
Did u realize if the carburetor lost performance without the manifold.

The shred head is a great head for solid gains for sure! The bike was running a 275 cam in this video.
Would this work on a ducar212
How would the steel valve one compare with this one?
This is the steel valve version with the 26lb springs .
