Suzuki Kingquad 300 Mikuni to Keihin Clone Carb Conversion and First Start!

[@iamdead3y3s47]

I first learned a few years ago how to re-wire quads an things watching your videos in fact you gave me advise regarding a warrior 350 quad, awesome hack! Now i can fix anything Chinese, and 80% of the Japanese bikes. I just purchased a pz27 with cable choke for an olde DPX-200 Redcat. Cable choke is a must for the quad projects. Anyhoo! Thanks for all the knowledge and i LOVE your Hoard of Goodies! Awesome!

[@HarveySpooner]

Iam Dead3y3s, Now that U know my 2 big tricks, the portable CDI box - wiring these things and the PZ27 carb, U can do everything I can do!!! U are a great student!!!! Thanks for the kind words, encouragement, watching, and commenting,,,, I'm glad my videos helped U!!!

[@matthewcampbell8071]

Can you show how to hook up the gas tank to that carb?

[@kruzchek1]

Can you please tell us how you ran the vacuum lines for the fuel pump and the petcock valve?

[@patrickwaugaman4929]

Yes please

[@Aliveinloma]

I am looking for the same info

[@joshuagarrett4149]

So how did u set the original gas tank up because it’s gas city fed and the carb is high then the tank the fuel pump won’t pump enough out or won’t work with suction

[@pinefighter1]

Sounded good,had one years ago.keep check on those rear c v joints $$$,thanks for the videos .

[@HarveySpooner]

Hey Pinefighter!!! I took a quick look at all the cvd joint boots and they looked fine.... Does not make any noise, clicks or squeaks, when it rolls, so, I'm hoping that they are good.... But, I will give them a good inspection.... Thanks for the good advice, encouragement, watching, and commenting!!!

[@pfun41]

You need a ultrasonic cleaner. I stopped buying carb cleaner after I got mine. It'll make old carbs look like new. The only parts I ever seem to have to replace is the needle and bowl gasket. I've done a number of the CV carbs. As far as Im concerned they're no worse than the Nikkis. That is to say, if you know exactly what to do they're easy to work with. The only real issues I see is ensuring the diaphragm works, real easy to pinch those or have a sticky slide. I had a mikuni bs29 on an Ozark that I tried to fix when I was younger and dumber and never got it right. Finally after a few years I dragged it out and sure enough it was a pinched diaphragm. New diaphragm, cleaned it out, and it hauls ass now.

[@HarveySpooner]

Hey pfun41!!! What do U use as a solvent in Ur ultrasonic cleaner? I like the PZ27 clone... They are cheap, easy to rebuild, and I can make anything from 90 to 300cc engines run on it.... Having said that, I have nothing against using the oem carb if it is reliable... This one has jets full of brown epoxy tar, does not look like they will come loose from the aluminum body... Given my techniques, I did not believe that a cleaning / rebuild would be successful.... Thanks for Ur thoughts, advice, watching, and commenting!!!

[@pfun41]

@@HarveySpooner Simple green and water. Trust me, soak it long enough in an ultrasonic cleaner and it will sparkle. I've had that thing clean out rust and corrosion.

[@troyladoux1953]

Thanks for posting the retro. I picked up a 2001-02 King Quad 300 last fall and like it a lot. It's my first ATV so nothing to compare to. I am in the middle of rebuilding the carburetor, first time for that to and it will not start now. I did not pay attention to the idle screw setting and I have heard others say screw it all the way in and then back out 2-1/2 turns. Problem is I am afraid to screw it all the way in for fear of damaging the idle screw. I bought it because it came with a plow and I plowed snow with it all last winter despite people claiming you need a 500 or larger motor. It worked great! Way better than I imagined. I hear these are special with their low gearing and differential lock. I mainly used 4wd in low for plowing and only used the diff lock when I got stuck. Amazing machine but then again I have nothing to compare to. Small and easy to store. I just hope I can get it running again.

[@adam31957]

It's a nice quad you scored big time

[@HarveySpooner]

Hey Adam, I always love it when a quad starts for the first time.... It is like bringing the dead back to life!!! Thanks for Ur thoughts, encouragement, watching, and commenting!!!

[@randyhodges3319]

What about the vacuum feed fuel pump? Did you just not use it?

[@topdogmechanic8261]

im not picking sticks here but how did you over come the intake vac for the fuel pump? What I mean @harvey spooner is these gas tanks are not gravity feed so it needs vac actuated fuel pump to syphon the gas from the tank to carb. keep the good shows coming in brutha I enjoy watching and hearing bikes starting up.

[@jamesbowers259]

Vacuum for fuel pump ?

[@tstricklin4808]

I just put a mikuni 606 on my 150 reaction and it runs great. Its not a cv but a mechanical slide.my sons bike has that same carb you used and its ok but seams like i have to clean it out every spring and again midway through the summer. I just had to do it 3wks ago. But outside that no complaints

[@HarveySpooner]

Hey T Stricklin!!! U R right, these clone carbs need to be cleaned much more frequently, especially if they fit around on an atv, outside, without an aire cleaner.... I'm lucky if they go a few weeks, I frequently just clean them before I even try to start.... Thanks for all the info, Ur experience runs parallel with mine.... Thanks also for Ur encouragement, watching, and commenting!!!

[@davekimbler2308]

I have heard that they are as strong pushing snow as the Honda TRX350 Fourtrax and we all know that is one of the best snowplowing ATV ever built ! To be honest she’s not the prettiest filly in the barn but she will take ya around the ranch and back !

[@HarveySpooner]

Hey Dave, I'm always happy when they fire up for the first time... I would like to rig a snow blower to one of these atvs, so much easier on the machine then plowing.... We are getting almost cold enough for frost tonight, we will probably miss it, but, not up state... Thanks for the info, encouragement, watching, and commenting!!!

[@davekimbler2308]

Harvey Spooner it’s suppose to be around 50’s here tonight which is weird for Minnesota this time of year ! Lol. I need to buy a plow for my new Honda before the snow flies which could be soon !

[@erichiles9568]

[@midwestmaniaoutdoorsjustin4105]

Where did you run the vacuum line for the foul pump

[@btac6481]

Could someone for the love of God point me to a diagram for fuel and air lines on a 250 quad 4x4 this year. Thank you

[@fan1701]

That looks like a winner now. I really dislike those vac operated carbs too. 👍👍

[@adam31957]

Please run the air box we have an 80s kingquad it runs so good it goes everywhere and for reverse it has to be in neutral slide lever back and it's in reverse

[@HarveySpooner]

Hey Adam, I may go with the PZ27 and the oem air box.... Thanks for the info, Ur thoughts, watching, and commenting!!

[@brianj123458]

I dont like mukuni carbs much either but I definitely like them better then those clone Chinese knock off carbs I've had nothing but bad luck out of them. I'm using them on 2 strokes and a 2 stroke seems a little more picky on carbs then a 4 stroke but just my opinion great video thanks for sharing and God bless you my friend

[@HarveySpooner]

Hey Brian!!! I have had good luck with the pz27 clone or carbs just like it.... Have not had much luck with the PZ19 version, the one used on the 110cc.... I rather just smash a pz27 on most everything now,,,, Thanks for the info, advice, thoughts, watching, and commenting!!!

[@ryno___2830]

Awesome carb swap, I've had the 2 wheeled version of this and it took some abuse over its lifetime. The 2000's arctic cat 300s are the same setup as this also. Have you ever thought about mentoring some younger kids on the troubleshooting of non running machines? Here where I'm from there some young folks that don't know how to start a lawnmower for crying out loud.

[@HarveySpooner]

Hey Ryno, Around me, kids don't seem to have any interest in anything that does not include their thumbs and cell phone.... I wish I could find a kid to help me out and who I could mentor.... So far, I am having no luck!!! I remember hearing the arctic cat used some suzuki 4 stroke engines on their quads.... I think they changed just enough to make parts harder to find.... Thanks for Ur ideas, the info, watching, and commenting!!!!

[@troycrowder9942]

i do like your adaptor for carbs very neet idea hate them kind of carbs to they are nothing but trouble got my recon running it had bad valve guides the dam intake valve broke in half i put a used one in and ordered new guides and valves and more gaskets

[@HarveySpooner]

Hey Troy, When the valve broke, did the top of the engine get hammered? I love the PZ27 clone, it seems that I can start almost any engine with it.... So, if I have a functionally solid engine, I know that a PZ27 gets me fuel, and my portable cdi box gets me spark, makes starting an unknown engine so much easier!!! Thanks for the info, Ur thoughts, watching, and commenting!!!!

My Honda Rancher is great for plowing snow, not sure how the king quad would be, but I assume it would do just fine.

[@itsme-p7t]

Eyup Harvey keep up the good work bud you help me out a lot :can you do a vid on how to test if these coils are good or bad "LML Ignition Coil Auto 125 Deluxe Lite Models Star CVT SF1830398"or any other coil thats simular thanks .Theres nothing on internet on how to test with volt/ohmms meter it has primary and secondary coils like any other but theres no real resistance reading for them

[@HarveySpooner]

Scooter Lover, I have seen folks quickly tap a 9volt transistor radio type battery to the primary on a spark coil and watch the spark when removed.... I have tried it, it does work, but, I always worry about damaging the coil.... On another note, with all the junk I have played with, I have yet to have a spark coil fail on me, not saying it is not possible, just saying, give my 1000+ coil experience, I have not seen it... Have only seen a few bad cdis, one got cooked on a hot exhaust, one showed up bad new, and one was in a box of parts I bought.... Have seen a few bad pulse generators... Most of them were physically damaged also.... I hope this helps.... Thanks for the info, encouragement, watching, and commenting!!!

Harvy do you have a 200sx fourtrax tank i can buy from you by chance im in north carolina i will pay for shipping

[@buildurtruckurway9118]

I'm thinking this swap on a bayou is going to be coming. The cvk carb is very problematic in cold weather the diaphragm gets really hard when it gets cold especially on an older bike and causes it to run like crap and only on choke until it's fully warmed up. The rebuild kits are all from china now and made out of an even cheaper rubber that's even worse in the cold. I've got 3 cvks all clean all tried on my bike and all run like crap until the bikes warmed up. I've plowed with my bayou 300 in low range and it can push a couple feet for about 10 feet then the wheels spin then you have to back off and hit it again. I'm sure the king quad would plow a little bit better being heavier, having a better gear selection and a front locker.

[@nestyjimenex7903]

I got a yamaha wolverine 350 no spark. I used your method an i got it running but not good its misfire and dont accelerate i found than its has 2 pick up coils help please

[@mikeshobbiesandrandomstuff]

Try new spark plug first.

[@csgmail4316]

Could be timing?

[@HarveySpooner]

Hi Nesty, Now that it is running, U are 1/2 way there!!! Normally, Yamaha atvs have 2 leads coming off the pick up coils, I would swap them, I would try the other pick up coil, always try a new plug... It can also me that Ur valves are too tight or have leak by, did U do a compression test??? Are U sure that Ur carb is ok??? No dirt or water in there, Ur jets are clean.... Ur engine timing is ok, Ur timing chain is not stretched and it did not jump a tooth.... Was it running before the spark gave up???? I hope this helps.... Thanks for asking, watching, and commenting!!! U R almost there, just some tweaking left! Good Luck!!!

[@HarveySpooner]

Hey Xguxdu!!! It could be timing, carb, wrong pulse generator, ( probably one for forward and one timed to limit the revs in reverse... Too tight valves, leak by on the valves....etc!!! Thanks for Ur thoughts, good suggestion, watching, and commenting!!!

Hey Mike, It never hurts to change the plug, especially if the given plug is a champion or one made in China!!! Thanks for the good suggestion, watching, and commenting!!!

[@twintwo1429]

Get educated HARVEY.

[@HarveySpooner]

Hey twintwo, Perhaps I was not clear in my video and for that I am sorry, but, my experience is that the body of cheap after market carbs is made of a lower grade aluminum or is not polished as well as most oem carbs... That lack of finish and or lower quality aluminum makes them more prone to corrosion and they seem to need cleanings more frequently than the OEM stuff.... I probably use 20 to 30 knock off carbs per year, I like the pz27 and pz30 knockoffs, I don't like the Mikuni carbs, oem or clone.... Seems that the PZxx series is reliable, easy to rebuild, cheap, and easy to get... Thanks for Ur thoughts, feedback, watching, and commenting!!!
