- Hey everyone today I run through the process I use when tuning the big 21mm carbs. It’s honestly easy once you get the hang of it like most things in this hobby. We also go over assembling the slide which I thought was good to include since there aren’t many videos on that.
If you enjoyed todays video hitting that subscribe button would mean the world to me.
Stay safe on the bikes and thanks for watching!
Youre videos are great for someone new to motorized bikes. Just built my own for my work commute and had issues with 4 stroking top end. Got a plan to fix it now. Appreciate you
That engine looks mean.. hey kid you did very well on explaining everything.. good job keep up the good work..
Thanks
This is the best carb setup video I've come across thus far..
Very good job. You answered multiple questions of mine.
Glad to hear that man
Thanks Keegan. Looking forward to seeing your next video.👍👍😺
No problem bro All I can say is it’s gonna be epic 💪
Great video man I love the genuine character you have. A dummy can understand you. Love the videos keep it up.
I try to make these videos as easy as possible to understand while still including all the import info you need to know when tuning a carb or porting a cylinder. I hate other channels that don’t share what they have done to their motors to make them go fast. They gate keep what modifications they have done. I’m all about sharing those things to the community.
That’s why I’m a returning viewer. Your very genuine about how you say things and while your videos may not be entertaining they are very informative
@@motorizedandrew3942 it’s hard to make motorized bike videos entering unless you do a lot of riding videos or crazy stunts such as wheelies etc.
You can cut some of the sheathing away on the throttle cable very easily. There's videos on it and I installed the dio reed kit on my yd100 with the nitrous kit and i love it! I cut away about half an inch of the sheathing on the throttle cable and that made it a lot easier
Thank you this is very helpful👌
I needed this tutorial because I have no clue what I'm doing. Thanks
What do you mean lol I thought you were running a nibbi carb on the saw engine
Why you Keep ignoring my response I know that saw got air leaks
@@keeganhache6667 I didn't see your comment, been busy with work. Oh dude air leaks everywhere. I'm about to go outside now as I hopefully fixed it all. The PWK is a long story
@@MikeNBikes well hope you can figure it out bro
@@keeganhache6667
1. Base gasket
2. Crank case gasket
3. Thick seal
4. Manifold adapter to carb
These are all the leaks. I motosealed everything and bought "Viton" FKM seals for $6. I got the hook up.
Only reason I'm running a PWK is to not need any manifold adapters, as it removes an additional air leak vulnerability
I like the clear carburetor intake tube......I switched my black stock oil lines to clear lines like those on my 2000 Buell so I could check/see oil flow by just a quick glance. Same with using clear fuel lines.
I'm going backwards, I started with a 700cc Yamaha then a 1200cc modded Buell. Now I'm down to a 80cc motorized bicycle lol.
Yeah man it’s great for seeing how your fuel to air mix is doing. Every time I down jet I can see a difference. My question is how did you go from them big machines down to a motorized bike lol.
Will the needle move out of place because mine does I’m trying to figure out if I may have put that in wrong
What is the negitive pressure adjustment for?
What jets can be used with this carb, can I just get off brand keihin pwk jets off Amazon? Or bad idea? Trying to make a 28mm version of this carb work with a Yamaha Blaster 200 needing to start around a 50 pilot/150 main
Did you end up figuring out the correct jets?
Hi Put on 21mm PWK on my engine it's a scooter 50mm bore 80cc put in a 35 air when I open the throttle quick it cuts out lifted the the needle to rich it's a bit better put is rich on tick over any ideas thanks.
Adjust your air screw 2 1\2 turns out from all the way in
I’m using a 38 pilot and a 105 main with 1 clip up on the needle at top speed I get boggy and then it comes out of it then back to boggy what would be causing that? Too much air?
Down size the main
what allen key the pwk need to take off the throttle
Where didd you get clear intake tube and what else could I use for the intake and where do I get it from? Also what size reed goes with these?
The intake tube I made myself but the inner diameter of the hose is 32mm hope this helps
i’m running a pwk on my new phantom v3. do you recommend the same jets? also when i switch out the jets how would i drain the float bowl so gas doesnt spill everywhere?
What I do is get a small container and hold it under the 17mm bolt and loosen until gas comes out. Don’t fully remove it you want to just crack the seal. Also the phantom needs way higher jetting. I would start out at a 140 main and work down from there.
@@keeganhache6667 gotchuu thanks!
Nice video man ! i have a same cerb on my motorized bike and i have a trouble i have 115 main jet and dont work .
What is the best jetting for this car main and low Thanks
Well does it sound rich? Smoke a lot if so then down jet the main and pilot also mess around with the needle clip to see what works best for you
what its your set up 115 main and 35 slow what
thanks
@@sleepered7692 just start large on the jetting and work ur way down
Hey do you know a good crankcase gasket maker or gasket
Moto seal is good stuff
Hi i was wondering do you modify your pwk carb by drilling out that tiney hole ive seen done in a smolik performance video tbh im rely not sure what its called or if you know what i mean i think its called a vacume hole or something lol its meant to help the motor pull the fule threw better and stop bogging that these carbs are known for on motorised bikes i dont mean the jets might sound wrird how ive described it its just for the life of me i rely cant thinn what its called i as just out of curiosiy by the way love your vids its grait that yourself and others take time to educate the motorised bike comunity ive learned a alot from yourself and many others here on youtube and facebook Thanks :)
Yeah the pwk is fine because the hole is already bigger. If you got an oko carb the hole is gonna be smaller. Just start large on the jets and go for a ride. Then each time jet down until it has the most power and response
Slide isn’t installed right there’s a little groove there in the slide hold the spring back put throttle cable there in the slide in the groove where it locks in then let spring go slowly keeping tension on the cable
Yeah it took a few tries but eventually I got it. I find once you have installed the slide onto a flat side it makes the NT look so easy lol
@@keeganhache6667 that it does also a good carb for the price
35/90. There. The golden ratio of the pwk.
I agree with you for the most part but I gotta say on the yd100 with the 105 main jet in it. The bike feels ridiculous when you get over 1/2 throttle. It just hits this power-band and before you know it on a 36 tooth sprocket your in the 40mph range all day. I won’t hit that often because I’m still breaking in this new motor.
Every one have a different number 🦾 . You forget the power jet . For the carb to work full potential 😎.
@@ELISRACINGTEAMthe “power” jet? Is that the vacuum jet on the air side of the carb?
IF i can get the stupid carb working .. then this video would apply. Doesn't apply to those that cannot start their frickin engine.
Just spray a little gas into the carb to prime it. I had the same issue with mine before. Since the intake is so long on the first startup you will need to spray some gas inside.
You can hold the throttle and get some gas in there be careful as you can flood the bowl
