Finishing off the Pit Bike (Pit Bike Engine Swap Part 2)

in this video, I make a custom exhaust up for my engine swapped pit bike.
I also make up an intake manifold so the carb would be on the correct side. Next I changed the gearing on the bike to make the gears longer by installing a 35 tooth rear sprocket. I swapped the front sprocket that came with the engine on as well as a 428 chain to go with it. Finally I put in a new tube and rim lock. I have also put new bars, tires and a seat cover on the bike. I had to adjust the valves on the engine also. To end the video off I did some riding. Thanks for watching!

Bikes running pretty lean, I can tell by the backfiring. I’d start by watching a few videos about carby tuning and try get the spark plug a nice golden colour. You’ll get a lot more life out of it

[@slimsqde7397]

agreed

[@obama2150]

Dude the engine swap had done heaps. You’re proper zooming. Looks so fun

[@GregBarling]

Yeah dude it’s so fun to ride! it’s 10 times better with the new engine!

[@remady5827]

I've been watching you since you did the motorized bikes, and I'm glad to see how advanced your videos are since than, keep up the great work!

[@GregBarling]

I appreciate that!

[@kanewest4155]

Your the man bro. So good to see a young fella tinkering with tools and bikes keep it up bro

[@GregBarling]

Thanks bro I will

[@Pitstershedder7517]

Made me smile watching you blast around on your pit bike you very good rider wow 😮

[@noahGCT]

looks likes its coming together nice man. keen to see more on it keep us updated !

[@GregBarling]

Yeah I will man!

[@PreferredAxe]

Good stuff man, great to see you making regular content again. Also wanted to say ups to the misso(?) on the camera. When you were riding the camerawork was outstanding. Starting zoomed in, perfect framing and following etc.. Really good, keep it up!

[@GregBarling]

Thanks dude I told her about your comment and it made her day cheers!

[@2smokemedia]

Bike absolutely rips! 👌🔥

[@kalemd27]

Yooo you're killing it on the pitty. I love how custom your going with the bike too. It would be really cool to see you on some sort of supercross bike at some stage. Keep the great content coming dude

[@GregBarling]

Thanks dude I recon I’ll get one sometime this year

[@marshallbrydon7916]

Nice keep it up i want to do some more building on my bikes

[@frankdicarlo6269]

Nice job dude! That thing rips!

[@xxshiftlockxx]

I've got the Pitster Pro MXR 155, so essentially the same bike. I ended up throwing away the trash carb it came with and got a genuine Mikuni VM24-512 carb for it. For my elevation 5k feet, I had to re-jet it from the stock Pilot 40 main 210, to a 20 pilot and 180 main. That made a HUGEEEEE difference. I'm sure your jets are off.

[@rumbei6944]

been subbed to you for ages but completely forgot about ur vids cus not been on youtube much, nice to see your still at it cus youre a cool guy hope to see you upload more ur vids are great💯

[@GregBarling]

[@DaveHiggins-k9t]

I've been trying to get my pit bike to be like that that thing looks fun for it's size

[@jackkelly5941]

Really well done i know ur not sure what your doing but u have done an excellent job

[@d1ktaatt0r13]

that pitbike is awesome!

[@pipejones1806]

Looks Rowdy!

[@boxatron365]

Nice one mate, i swapped my pitpro 125 to a zongshen 160 a couple years back. it's definitely running lean, go a bit up on the fuel and see how it reacts, those motors do hammer when they're running good. I must say i went through about 4 back wheels over a couple months of hard riding, the spokes seem to give out on those chinese rims quite quick. Nice video keen to see more 👍🏽

[@ericwilson2585]

That engine sounds like its got a really good torque curve number, and the way you make an engine fast that has a lot of torque is to give it a high geared final drive ratio, that is what in a sence converts torque into horsepower.

[@slimsqde7397]

your welds are decent man, tig welding isn't easy, just needs to be sealed haha, and its way cooler that its something you made even if the welds arent picture perfect

[@jeroenyoutube5621]

Your flying in that thing

[@GregBarling]

Haha yeah Jeroen!

[@AllTheBoost]

Bro deleted 2/3 of his sprocket bolts after he doubled his power and put a smaller gearing on it. Send it 🍺

[@joshuavardy3144]

Hey Greg you reckon you could try and get sturdy, keep the good videos up champ 💯

[@alexstanton2033]

that is awsome greg, please more moto vids!!

[@GregBarling]

Okay Alex 👍

[@jamespierce2415]

I’d pay large sums of money to have an Austrian pit bike excursion

[@InfiniteVibration]

Yo that bike is rippin

[@JohnHoran-z4q]

Love your vids bro. Dude can send it haha

[@evanoc12345678]

that thing rips !!!!

[@GregBarling]

Aye! 🤙

[@dccracker7922]

You got potential. Gotta post more tho if you wanna go anywhere

[@Altie8]

noice i learning on the way while watching

[@moustacherider01]

Bruz , you should do merch !!

[@buzzedriders]

Epic Bro!!

[@GregBarling]

Thanks 💯

[@gazza70cr]

Did you do the upgrade on the fork and any other work to the bike Greg?

[@jonjon2times576]

Dope Bro i have a Apollo Rfz 20 max the adult size and im currently trying to make it faster n 😂 my only option its going to 190cc and a better carburetor

[@AllTheBoost]

Use a rubber coupler on the intake next time. That with two strong hose clamps and you probably didn’t have to try to weld that aluminum pipe with your steel wire 😂

[@cheekohanratty3271]

Wire wheel the weld joints that will clean it up a treat

[@GregBarling]

I’ll have to do that mate cheers

[@amanteapasionado6836]

Shoulda got a yoshi slip-on or even a replica from amazon since you were built your own exhaust, it would have looked sicker

[@vincentlui819]

Hi man! Good video. Still learning how to work on my bikes. What were you doing on 11:16 and why? I would appreciate any explantation!

[@kaosadventures]

Bro save your coin and buy a good dirt bike take your time you will pick up a good one cheap enough just keep lookin. Love the vids keep it up

[@GregBarling]

That's the plan mate 👍

[@kaosadventures]

@@GregBarling legend 🤘

[@somlysom6315]

What you can do is flared out the tip of the new pipe then it should fit snug inside the exhaust

[@AngusBrady-st2gi]

Get a klx 110 rL they so good

[@JoeMaxFpv]

Did you do anything to the front forks? Mine is a bit squishy. Wanted to stiffen it up without spending 600.00 on insanely expensive brand name forks. I’ve heard about the heavier oil and spacer thing. Is that worth it?

[@cjstricklen2930]

Yo greg, your welds may be turning out grey and raised because you’re using too much heat and making up for it with filler. try turning the heat down and only using filler when needed 👍🏼 hope this helps a little

[@GregBarling]

Thanks a lot mate 👍 I will try that out next time I do some welding

[@henrydrewett6516]

A 28mm nibbi carburettor would solve any lean issues and give you more power up top

[@sagesends]

fucken shredding!

[@GregBarling]

Thanks bro

[@absolutelegend5519]

You need to make more videos, you have over 70,000 subscribers!!

[@jaydenorr1610]

Ya better turbo it Greg

[@lg_ballgloves7486]

Can you make a video showing how to jump pit bikes? Would greatly appreciate it.

[@GregBarling]

Maybe mate, I just send it I don’t know how to jump them this was the first time I really have jumped it

[@Pitter_crewzz]

What front tooth sprocket are u using and rear as im concidering changing my gearing up

[@GregBarling]

15 tooth man

[@Mroswaldo16]

Isnthis those ebay/amazon 140cc engine?

[@RaNdomguy76840]

Whats the plastics called

[@ericwilson2585]

I woudn't put JB weld on the inside of that intake manifold.... If it comes off inside there, guess where its going???

[@megamoose6448]

What brand is that ripper?

[@GregBarling]

Pitpro

[@justhow23]

hey dude what cc is the motor

[@GregBarling]

155 man

[@Slicknickcampbell85]

Hey what’s up Greg! If you are having any issues with jetting or air fuel whatsoever…you should refer to stock and then play around and see what the bike likes… obviously when you add a pipe stock jetting is no longer sufficient as there is a lot more air being pushed through your motor. I have a klx 110 and I got a pipe and the thing would spit flames like yours. Also you mentioned your intake port, if there is not a perfect seal on the intake manifold after the carb, then your motor will run extremely lean due to too much air. Now also with pit bikes since me and all of my friends like to bang these little things off rev limiter all day like yourself, you should probably run a fuel additive just to keep things a little more foolproof in terms of catastrophic failure. Lucas makes an oil fuel treatment that helped me out a lot. Blew 2 top ends before I started using the fuel additive and now I have about 140 hours on a Cammed 110cc with a Bbr rev box and some other bolt ons…They smell a little bit like burning oil but they are a lot more reliable. Anyways Cheers bro, been following your channel for a long time. If you have any questions feel free to message me.

[@GregBarling]

Thank you bro for this information! I haven’t really played around with anything on the carby I think I should move the clip on the needle to give it a bit more fuel now that it has a pipe on it. I’m definitely going to get some of that fuel additive a try! Thanks again

[@specificocean270]

What chassis is it?

[@GregBarling]

crf 50 style frame
