How To Jet and Tune that Pwk Carb! Tips on Using The (Stock Cable)

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

Great video man I love the genuine character you have. A dummy can understand you. Love the videos keep it up.

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

I needed this tutorial because I have no clue what I'm doing. Thanks

I like the clear carburetor intake 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.

Will the needle move out of place because mine does I’m trying to figure out if I may have put that in wrong

[TalariaMonster]

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?

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

[sleepered]

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

[Smodlee]

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?

[dario]

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?

[NathanMorgan-jxsx]

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 :)

Hey do you know a good crankcase gasket maker or gasket

[jdmfanatic]

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
