All of the parts you have to go through to find the right part so we know what to buy.
Very very generous of you to share all of this information free of charge. You spend a fair amount of money getting the wrong parts several times and finally get the right part and we all benefit from your hard work and money spent.
That is extremely good of you sir!
I appreciate you noticing. Thanks. It is fun though. I do have a collection of dud parts tho. LOL
That carb looks perfect if you want to add a blow through turbo because it has that extra jet.
You’re lucky you just need to have one tune. Up here in frozen land I have a winter, spring/fall and summer tune. Great video.
So true. LOL
Mann.. just wanted to tell you, your videos are fantastic! Keep up the great work!
Liked the format.... sweet ride
Loving the 50cc vids thats what I have and want to get the most out of my 50cc. I weigh ALOT. (270ish) And i dont have the expertise to go to a 150cc weld on kit. Please keep up these awesome 50cc vids. Have you done a vid on the 50cc BBK kits?
No before and after vid on the BBK. I got that one with a improperly installed BBK. I am looking for a POS cheap used 50 on marketplace. I want to take one from stock all the way up.
Id watch the hell out of that series!!!@@GhettoWrench
Right good stuff man .. I'm running 43 45 with the 50cc
Nice. Still 49c ? I'm struggling with a 49cc trying to get it past 40. I'm blaming this florida heat. LOL
Badass man!
I got a top speed of 56mph today with that carb. Holy moly what a power increase even with the glixal gear up kit it just kept going. next i'm going to get the 95mm variator and see what I get.
That's awesome
Would like to see ghetto wrench testing on a airbox test, velocity stack, pod filter, snorkel, maybe modified airbox. See if any advantages to pod filter besides airbox. Smooth airflow into carb or no change. Vacuum gauge on intake or some good ghetto wrench testing 😂
I like it! Ram air? LOL
@@GhettoWrench as a old 2 stroke guy your self, you already know 2 stroke love the airbox. 4 stroke seen both arguments and some say yes some say pod . Could ghetto wrench break the myth lol. Can a smooth airflow through the tiny intake in the head make more power ??
@jeremyhope6869 tiny intake. Increased portrait velocity. That is old school. LOL. Ya I always ran an airbox on my road race bikes. Instant volume. Pod filters on a gsxr is just dumb. An airbox would prob help a GY6.... especially if I could force feed it from in the front.
Like that idea, find a classy way to
mount a scoop, or full on mad max huge bug catcher hanging off the front of the bike lol
Thanks man, got the same set up as you and that carb has been no fun tuning. I tried all 3 pilots that came with it. Smallest is 35 and I get a bog when I try to open it up wide from and idle. Bogs down bad, any suggestions? I tried 40, 38, and 35 seems the best. Gonna pick up some pilots tomorrow, looking for advice.
I think I was down to 28 on that pilot. I can never tell if the Bog is rich or lean when just off the throttle. So I drop the needle all the way lean then start going up or richer 1 step at a time and see if it gets better or worse.
You the man! Thanks. I'll give it a shot tomorrow. Will KIT on my build also. I have a white gen 4 maddog. Similar to your other one. It's nice! Ty again
Crucial!
Critical Mass Acceleration!

Thank You Ted
for Your postings!
It is Real Helpful.
Love Your Work Man.
Now that my bike is running you got me looking into this carb upgrade 😂 Do you recall the size of the air filter for this? It doesn't come with one off Amazon and I couldn't figure it out.
Thank You!
I think it was 50mm. The carb you get will say the size it needs on the ad. So check that. Is yours a 50? Or does it have a big bore kit?.
Yes, mine is only a 50cc. I noticed since I had to replace the cdi box to get it running again I've lost 5 miles. Before replacing it I was hitting 40mph and now I'm hitting 35mph.
Will this not work if I don't have a big bore kit? I'm new to all of this with a bike. If not, what would be an upgraded carb for my stock 50cc maddog gen 1 bike? It has the 1P39QMB in it.
@jayb5623 check out my newer videos with the white maddog in the thumbnails. I did the 21mmPWK on the 50cc and it wasn't great but worked. I then did a video with a Nibbi 19mm and that worked better for the 50cc.
@jayb5623 I lost 1mph with aftermarket CDIs compared to the stock one. Should have been that much slower. Idk what that would be.
What was your RPMs at when you hit 53?
No idea. No tach on that one. I would suspect 8800 to 9000. It has a 95mm variator so that geared it up a bit
@@GhettoWrench cool thank you! Love the videos keep it up
What would be the best place to buy the 90cc bbkit
I’ve been looking at the rolling wrench one, but it’s kind of expensive
I got my 171 kit at rolling wrench. You know you get good legit stuff from him. The 90 kit for the 50cc I got from NCYstore.com. always great service from him. I got the Naraku one.
@@GhettoWrench thanks man yeah I’ve been ordering a lot from NCY store. I definitely was looking at the rolling wrench. Bb kit I’ve ordered stuff from him before. Thanks for the awesome videos man really helps out appreciate you
@@GhettoWrench so is the biggest bb kit. We can go with is 54 mm.
@randyalmonte1431 I'm not sure. NCY store has great descriptions. It says the kit yields 89cc and if you upgrade to longer stroke crank then same kit yields 100cc. Thats why a lot of people call it a "100cc" kit.... but it is not. Ihave not seen one bigger.
Can you upgrade my bike I’m not good with mechanics
You can anything woth youtube and some harbour freight tools
Look at the carb. From the side if the mixture screw is in front of the slide towards the engine its a air screw out to lean in for richen. If the screw is behind the slide towards the air cleaner it's a fuel screw out for rich in for lean keep at it you'll get it some times it takes a while to get it right
Oh cool. Great info... thanks. I know sometimes they would do opposite. That is why.
You got that backwards. It's an air mixture screw if it's closer to the air intake and it's a fuel mixture screw if it's on the engine side. Screwing it in equates to less of whichever type screw it is, less air or less fuel.
@GTECHEE ok thanks. I am about to put another PWK on a 50 so this helps a bunch. I screwed the idle up on that one.
If you get to rich it will be flat on the top end
Your turning the mixture screw the wrong Way you need to learn what you're doing before you make a how to video.
@user-jh2zz2sc3i don't leave me hanging, how do I tune it?
On this set up, the screw is for air jet adjustment so counter clockwise will give more air. I just gone done with a 63cc gy6,ported polished with stock cam. Ended up using 33 pilot and 88 main with power jet still being used. That is the smallest cc engine I will use this application for. It was a nightmare to tune. A lot of the flat spot at take off can be eliminated by using an emulsion tube out of a 24mm cvk carb. The 18.mm carb emulsion tube does good up to 3/4 throttle and then goes erratic because the smaller emulsion tube is a little too short to reach the base. Hope this helps someone as well
@gennygauck4974 this is great info. Thanks. Ya I was tuning that pilot jet all backwards with the air screw. Live an learn.
