Just wondering, do you have a tach on this bike? I'm starting to wonder if the gear ratio is too long. Maybe it's getting to a point where it just can't pull the bike. I don't know what the cam is supposed to pull to but I feel like that setup should pull pretty high in the rpms. I'm wondering what it is reving to? Sounds healthy as hell though man. Keep up the good work.

[@Black66]

Yes, the bike gets a 58MM stroker kit and Methanol in up coming videos. Its fun finding out what the cam and head will do in a smaller package in the mean time. Thanks for watching!

[@armandosierra731]

I love that he's the only one on KZbin that is reviewing the PK stuff and is honestly just letting the math speak for itself

[@dannymccullagh8211]

I love this channel and all the combos!

[@steveblottenberger1097]

You're doing a fantastic job and you remind me of me I just don't have the KZbins like you do keep up the good work you're really kicking ass

[@bernandoturner4840]

This Thing Sounds like A Harley PanHead…. Not your Average Kids Mini Bike..😆🤣😆

[@rogermcdonald1607]

I always look forward to your videos to see what you are comparing next. Great job man!🎥😎🇺🇸

[@Black66]

Thanks!

[@raleighparker7046]

Black, my man. You do the most consistent testing of all. Thus your conclusions are mostly sound. With your welding skills, it would do your fuel adjustment setups much more surety and less guesswork if you built a header pipe with a wideband sensor, that could be used on a gamut of your engines, perhaps not in its finality, but again consistent testing to achieve optimum AFR, THEN the final test would be, going to the actual header pipe for the bike (no WB sensor), and get I suspect an even better improv. I mean you probably have a 3-step header that would install and run on a bunch, even if like out the side but with a well installed, sensor weldment about mid-pipe, aiming inward under seat. Just a thought, I’d kick in on the WB kit, you’d have to make the test-pipe(s), I think you could find the weldments and make 2-3 test-pipes with WB sensor ready to plug right in.

[@dmann1209]

Sound good and looks fast on the video. More Please!

[@Black66]

Thanks! New video with this bike on Saturday.

[@TiaanRides]

Always love watching these videos

[@raleighparker7046]

It would also work with the various fuels you play with. Imagine if you could get full range AFR during your tests and have a log of your 0-30s and TOP speed tests. Again, I’d kick in on the AFR WB kit.

[@Black66]

👍👍👍

[@dennispage5333]

Thumbs up, You do a great job.

[@Black66]

Thank you very much!

[@BSRjboii]

Lost a little in in the bottom end but clutch can be set a little lower for engaging think it will snatch and take off a little quicker Fasure

[@kylesyx8432]

Trains are so cool !! So is that badazzbike!!! 👍❤

[@anthonyh.1512]

I’ve noticed that the size of the carburetor doesn’t always make the difference. As long as it’s tuned right it will run just as good. I’ve been using a 28mm. And it works great cause it’s tuned well, but some people say it’s too big.

[@colbyturbeville2946]

The carb depends on your intake valve size normally

[@demetricwalker123]

Put a 13 Tooth sprocket on the clutch

[@richpalmisano1740]

"Might suck in a rock or a bee, but that'd be ok..." Not if you are a bee...lol Great stuff as always.

[@Black66]

Thanks! LOL

[@stuch77777]

HOW did you knowthe right length push rods you needed?

[@Black66]

I use an adjustable pushrod to find out the length. You can also use a dial indicator.

[@NVScrapper]

Thanks for another great video! 💯💯

[@ol-man-duffyj688]

Also on the 28 mm carb but a camera on the high speed jet tube. I have only seen ONE actually pull more fuel at WOT. Mine winds up higher when I close it sadly. 🤷🏻‍♂️

[@HappyHands.]

196cc stage 4 vs 224cc stock.... What do you think??

[@kylesyx8432]

That’s crazy fast ! I’d be a lil scared to go any faster on the Chinese bikes! My lil stage 2 bike will go 56-58 but I like bottom in to be strong ! I live in the middle of the mtns so I gotta have it set up this way! Cool video I enjoy all of them. I wished I had more time to have more hobbies! But I enjoy these small engines I just ordered a tilli 212 and next try some big valves out ✌️💕

[@Minibike-Isaac]

You should try a smaller sprocket on the rear that will add alot of top speed too. Try a 60 so you still have some trq but gain a few mph and break 70 😎

[@Black66]

I have broke 70 on this bike. Check out the Mega Moto playlist. Thanks for watching! kzbin.info/www/bejne/roebmmhvlqyIl9E

[@jamesfalvey77]

When I watch your videos (all the time) I noticed when you beging your road test you don't give full throttle until after you built up some speed first. Is there a reason for this?

[@smartassist9700]

What would one cost to make? I’m not pushing for top speed. I need a reliable scooter to add proper lights to and tag it. I need a way to drive 40 miles round trips 2 lane roads. Avg mileage to please? U r genius!

[@miguelpagansr6128]

Nice bike, do you have a link for the muffler? It’s starting to look a little scary,

[@Black66]

Thanks! Here is a link www.gopowersports.com/exhaust-silencer-1-5-16-with-hd-ss-clamp/

[@232Stangpwr]

If you have the clearance go 1.3 and ARC billet extended rod. Also methanol (properly jetted) will kick that thing in the ass and get it rippin.

[@Black66]

Tested MANY rods at this point and clearanced quite a few engines. Have used Methanol on many different engines and combinations. Raced Karts for years in the 1980s. I don't know everything but I have had a lot of fun over the years. If I can't have fun with this stuff then its not worth doing for me. I know some take this stuff very seriously. I don't. Its mainly fun for me. Check out the pictures on the community tab.

[@jamesgravel7755]

Question. Why did you add jet to the main. Couldn’t you just open up the 3rd circuit. Just put a turn or half turn in the power valve and achieve the same results? I would think you could have left the 110 and just opened up the power valve. Or are they not the best on these PWK carbs. I used to use the add on ones in my snowmobile with Mikunis and kept the midrange a tad lean and at wide open the power valve added the fuel I needed. But I’ve never used them on thes PWK’s

[@duffy1298]

What phone app do you use for testing? I’m building a bike now I’d like to do similar testing

[@Black66]

I use a Dragy performance meter for 0 to 30. I use digiHUD on the phone for top speed

[@Jyoosh_]

What’s the motor mount slider you use ? Great build buy the way !

[@Black66]

Thanks! Check out the build videos on the Mega Moto playlist. It shows the Kart mount that I used. kzbin.info/www/bejne/jJPGoXRmn8mGf9k

[@PrinceoftheLightSkins]

What springs are in the Paul's Kart head?

[@Black66]

37lb

[@lawrencecoleman7850]

With the performance upgrades you have done to the engine you should be going a little more than 69 mph

[@Black66]

heck out the Mega Moto playlist for many combos with this bike kzbin.info/www/bejne/jJPGoXRmn8mGf9k

[@markrice3478]

Black66 what pilot and main jet did you start jetting the carb with

[@Black66]

I do so many of these video I'm not sure.I live at 3700 foot elevation so my jetting could be different than yours, Check out the Mega Moto playlist. I do show the jets used in some of the videos. kzbin.info/www/bejne/jJPGoXRmn8mGf9k

[@cordovaar]

I have a coleman CT200u-ex built 224 flattop piston, billet rod, hot 275 cam, 28lb springs, champion rockers, and a 10,000 rpm flywheel VM22 Chinese knockoff carb. bike has original gearing i cant get it over 38mph . at full throttle it bogs/ cuts out. runs good at full throttle until about 25 mph then i have to back off to a little over half throttle. looking for any advise on understanding what I am doing wrong

[@fuckingbasterds]

You're lucky my bikes never run

[@jakesdronelife6307]

Do you have to do anything special to get this motor started I just got one an it’s tough to get started

[@giovannquinones3497]

4.46 ratio is too heavy for the engine, and paul's camshaft is too big for that engine.

[@Black66]

This bike gets a 58mm stroker kit and Methaonl in upcoming videos. Its fun seeing what the cam and head will do in a small package in the mean time. Thanks for watching!

[@mitzu8386]

I don't think those rockers work with valve caps you might want to check that!

[@Black66]

I am not using lash caps on this combo . You notice later in the segment the caps are off. I also swapped out the pushrods from 5.110 to 5.160 without the caps . Check out the playlist for more combos with this bike!

[@mitzu8386]

@@Black66 My bad! I saw them on your table at 45 sec into the vid thought you were using them.

[@johndeesfpv9289]

bigger main jet.

[@Black66]

I live at 3700 foot elevation. My main jets tend to be smaller than someone living at sea level.

[@johndeesfpv9289]

@@Black66 I see was just wondering if you tried going up ?

[@fuckingbasterds]

​@@Black66then my stock jets must be especially small for my vm22 Chinese knockoff carb. It stalls when I throttle the gas. Need a 115 main jet and a bigger pilot jet. Right?

[@steveblottenberger1097]

Hey my friend sounds like your gear ratio is too high you know for top speed sounds like it's just not coming out of the hole with no RPMs

[@shrugger1]

Wake it up? Like with amphetamines?

[@adamjankowski4315]

So in all of this PK stuff added zero performance gains. Good to know

[@Black66]

That's what the channel is about. Testing different combos and having fun with mini bikes.

[@lawrencecoleman7850]

Bro I think you should to change up the gearing

Had this bike well over 70 MPH . Check out the Mega moto playlist kzbin.info/www/bejne/roebmmhvlqyIl9E

[@johnk6346]

☹

[@steveblottenberger1097]

Stay away from the methanol it's nothing but trouble it dilutes the oil I would just stick with my cam2 racing fuel don't mess with the methanol because a lot of us can't afford that and you just going to confuse the crowd

[@Strict30]

m5 much better

[@Black66]

Yes, I will use it along with a 58MM stroker kit in upcoming videos.
