Man that fmf pipe is really super loud :)

[@Richiehervig]

So crisp! That is easily the fastest pw80 on youtube rn

[@EthanHervig]

Thanks bro! I tried to build the best one out there 🔧🔨

[@theboogieman401]

Yeah right I’ll smoke that thing on my Pw80 lol sounds good tho I got mine to go 66mph FMF Pipe

[@nashgautney8117]

did you change the sprokets or mess with the carburetor? I got mine to go around 40mph and was happy Im building another one now🤙

[@EthanHervig]

nash gautney Yeah I changed our the jets for bigger ones and changed the front sprocket to a 13 tooth (from 15) and the rear to a 39 tooth (from 32). Made a huge difference in the acceleration of the bike.

Thats pretty sweet! I have an 87 bw80 the fat tired version I built it im looking at more performance parts but they aren't in stock so idk if I have to wait or what my piston just shattered I ordered my best rebuild kit yet! It's on the way

[@bxballa17]

are you running premix or oil injection?

[@EthanHervig]

I run premix in my PW. I just drained the oil tank and disconnected the oil line from the side of the carb. There's no need to get an oil pump blockoff if you're looking to bypass it.

[@belizeandinero8259]

Dope I want one 🏍

[@EthanHervig]

I got mine for $200! You might be able to find one for $500 at least these days...

[@dirtbike3768]

What rear shock do you have in this bike looks good

[@EthanHervig]

It's stock! It just has a 1.5" spacer on it so it sits taller

[@dirtbike3768]

May I ask the rear shock you have fitted to the PW80 please? It seems longer than stock.

[@EthanHervig]

It's the stock shock with a 2" extender on it.

[@Drz_noah470]

Yikes those main bearings are screamin. But the fmf sounds minty

[@EthanHervig]

Yep... she still runs great! The engine sat with water in it for who knows how long and it was seized solid so I poured some oil in it and forced it over with a wrench and ever since then it runs just fine. I didn’t put a penny into that engine 😂

[@mototommy5525]

Running well to rich on the main jet

[@EthanHervig]

What are the symptoms of that? I thought I got it pretty dialed in my jetting video.

[@mototommy5525]

@@EthanHervig when your revving the nuts off it in neautral it is spluttering at the top of the revs, there's to much fuel and not enough air

@@bradenclifton45 Yeah right now it’s bone stock engine wise so a new piston is definitely in order

I like how the bike is lifted compared to mines which is bottomed out. Might be blown shock not sure! What shock do you have installed?

It’s the stock shock! Just has a 2” spacer on it

can you please advise what rear shock you have? the stock one sits alot lower then yours

I am running a 39 tooth rear sprocket with a 13 tooth front sprocket.

[@randyholloway6132]

What chain link

[@bukumaze3861]

how tall are you? im trying to figure out if a pw80 would be too tiny for 6,2 me

[@EthanHervig]

I am 5’10” and it’s pretty small but I raced it somehow and didn’t die 😂 I would say if you’re any bigger than 5’8” just go for a ttr110 because pw80’s are just kinda small for being a pitbike but I’m managing it

[@andrewyork8513]

done anything with the clutch? i know you can change when it catches.

[@EthanHervig]

I didn’t change the clutch engagement yet, maybe in the future I’ll mess with it!

@@EthanHervig seems to be ripping pretty good as is! just picked one up, and can’t seem to get close to this. will try some more things in the morning. still trying to get it to idle. lol

Is this a yamaha PW80 and 2001 because I’m 5,8 and thinking about getting it and does it hurt your legs when you sit on it

[@EthanHervig]

Team lored it is a 2005 PW80 and it’s probably pretty small for you. It’s pretty tiny for me and I’m around your hight. Maybe go for a ttr110 or something that size.

[@jonathanroy9112]

depends on what your using it for. got a 2006 and I'm about 5"7 maybe taller I'm still growing I got no clue. if you want a bike to mess around with or ride around whenever as like a pit bike this bikes great at that if you want a bike to be your main bike to go ride pits or to like do anything else it's not the bike for you it's just not big enough to make sense

I have a peewee 80 2007 model I'm 10 years old and I love my peewee 80 2007 model dirtbike

[@DirtbikePuruit]

[@cousibas31]

Hi, What sort of rear shock have you.

[@EthanHervig]

I have the stock rear shock with a 2” X-Tender spacer on it

[@AllanGadd]

Mine all i have to do is put the fuel in it because they have a automatic mixer for the oil and fuel to mix

[@William.092]

That silencer should fit a jr80 ?

[@EthanHervig]

It might, you’d have to test fit it and maybe make a custom bracket for it

[@AridersLifeYT]

no it wont fit.

[@Turboduckng]

My pw80 has an fifty same spec?

[@julianalatorre-pianosheets3993]

Hey I got a pw80 rear shock spacer. I’m in the middle of assembly. I can’t remove the eyelet to install the spacer. Any ideas?

[@EthanHervig]

That’s unfortunate man... I guess they’re tough to remove. Maybe put the shock in a vice and put a thick screwdriver through the eyelet and turn it? Hopefully nothing breaks, and maybe some heat would help

[@julianalatorre-pianosheets3993]

Ethan Hervig I’ve put it in the vice with vice grips holding the shaft and some heat. Just can’t seem to get it to budge

[@EthanHervig]

@@julianalatorre-pianosheets3993 Wow, bummer... makes me wonder how they put the shocks together! A lot of torque I guess. Let it soak in penetrant for a while. Maybe put the eyelet into ice, leaving the rest of the shock exposed and when it’s time to put it in the vice, torch below the eyelet where the threads are and give it a wack with a hammer.

[@randyholloway6132]

That spacer only works with oem shock or uall never get it off

[@johnrobbins3087]

What mods have you done to make it that fast??

[@EthanHervig]

I installed a bigger main jet, changed the sprockets for faster acceleration, put an air filter on it, and installed Boyesen Reeds and a full FMF exhaust system!

[@zachglick502]

where'd you get the pipe?
