PW-80

[HaremScarem]

Anybody know of any tricks or tips on getting a little more performance from the tiny 2smoker. I have the washer removed from the exhaust pipe, but thats about it.

[Blitz393]

uh... holes drilled in the airbox? does it have a throttle stop?


hehe.... take out the PW motor and put in a YZ80 mill.....


i wonder if those crazy crusty dudes with the tricked-out XR50's have aftermarket pipes for the lil' zinger? hmmmm....

well, i just exhausted all of my infinite knowlege on this post, thanks a LOT ya bum...

Not as familiar with the 80, but on my little girls 50, I played around and got a lot more out of it by also removing the spark arrestor. The exhaust is really restrictive on these bikes and I think that there are ponies there to be had by opening it up, but I am not sure if any pipes are out there for it.

Given the suspension limitations on the 50, I intend to get her through 1 more year on the 50, then on a KTM. THose little bikes rock and they have great suspension.

Thanks for the reply. I was thinking along the same lines. The current muffler insert has some sort of "spiral fin" setup, which I'm thinking of cutting out.

[FFRacing]

The "spiral fin" is nothing more than the SA. Doesn't greatly effect flow.
These bikes(pw50/80) were intended as learner bikes. Suspension and handling are very limited and the thought of making them faster than what they are intended for is down right scary.
let you lil riders learn the basics on them and when they are ready, get them something that was meant to go faster. Just my opinions. Tryce

[Keetoman393]

Have you looked into the BBR stuff to see if they might be able to help? That stuff is expensive but man they make some trick bikes! Good luck and keep us posted on what you find.

I just installed an exhaust insert from a TTR-250 into the 80.
We'll see how that does, but I think Tryce is correct. I wait till junior beats the gaskets off the thing, then upgrade!

Thanks for the reply Men... Much respect to all

Ok I'm new here but. There are a couple of things to do to the little 2 stroke. First, get your little one some aftermarket bars just to make it look good. Second, buy some stiffer shock springs from [Only registered and activated users can see links. ] Third, buy a fatty pipe with powercore 2 silencer from [Only registered and activated users can see links. ] Fourth, buy some graphics for the pw from [Only registered and activated users can see links. ] Now your about done. Open the airbox up a bit, fiddle with the jetting, get some nice chain and sprockets and your ready!
Have fun!

[Blitz393]

oh man, i gotta hand out another WTATM to TTRracer :

Welcome To All Things Moto! you sure have some great info, and a REALLY tricked-out bike.. i had a '01 with nothing but a dunlop 752 rear tire, opened airbox, widened filter base, and removed SA for the track.

hope you visit often and post often, too. any questions, just ask and you'll get more than enough info.

Thanks for the good welcome, Blitz. But, I'm not the one with the tricked out bike, I bet that YZ and Z 400 are mean. If you haven't gotten the springs from BBR yet, you have to. Makes the bike much more rideable and takes quite a bit of air to bottom it. Hopefully my list of TTR mods will grow very soon.

Hey, My 9yr. old son has an FMF setup on his PW80 and loves it.
We are looking at porting and polishing next. Also we have a set
of 87 YZ80 forks that are going to be installed. And we are looking
for an old Fox air shock for the rear end. After that we are going
to eliminate the autolube and go to pre-mix

That is cool, be sure to let us know the results. The PW's are so detuned that most simply move on to a new bike. I am anxious to hear how much more juice you can coax out of it.

A couple of other things I found out about the PW. Now I'm not 100% positive this will work but I think it would. I think the PW80 and TTR90 use the exact same shock. Now Works Performance sells a shock for the TTR90 but not the PW. Really I'm about 99% sure there the same shock but you could ask someone else who may of done it. They make the shock custom built for your kids weight and riding style. They even offer the shock for up to a 210lb rider: The YZ80 fork sounds like a good idea but I'm sure it would jack the front end up. So you would need something to balance it. I've seen a DRZ110 with RM65 forks/shock/swingarm. So possibly RM65 forks with a Works shock in the back: I dunno I'm just tryin to give you some ideas.

[Badbird69]

Hey thanks for the info, I think it's the same rear shock also.
We are not going to use the yz fork's, not because of the height
but because of the weight. The fork tube's will slide up past the
bar's, so we could find a happy medium there.
We did put a 14(1 less than stock) tooth counter shaft sprocket
and it help take out the bog between gear's. There are a few other thing's that we are loooking at, but that will take a few week's.... Thank's again

I see a few responses about how to tine up the PW80 and the pipe is a great thing to start with. The FMF Fatty and PowerCore II will help with the restriction that the factory applies. Also, Works does make a shock for the bike and can be ordered by weight, rider style, etc. they actaually make two different shocks, one that is standard in legnth approx 10.5" with 3.7" of travel and another that is approx .75" longer, but gives over 5" of travel and raises the rear just a bit. I also met a great source for one off graphics and he will make anything you like for a reasonable price (GraphicMX.com)(attn:Marsden) he did some custom graphics for our PW80 (tank and fenders with logos etc.) for a total of $70 shipped to the house. (highly recomended) My question is...does anyone know if a CDI box is made to remove the rev limiter on the bike? We need to catch up with all of these XR50 folks and the mods availble for them....

[Badbird69]

The info on the rear shock is very helpful. Another thing we did,was to install Boyessen reeds
I dont know about the cdi/rev limiter thing.

[Parvo]

Badbird69,

How did all the mods work out on the little PW. Want to do the same. Any suggestions for or against. I am hopeful, but worry about jetting... HELP:-)

[eyreracing]

All the mods we have done turned out well. We did the graphics, rear shock, renthal works chain, FMF pipe & silencer and rebuilt the front forks to stiffen them up. Didn't have any issues with the jetting on the bike after changing the pipe and I think you will find the same as the pipe is very similar to the factory pipe and uses the factory cover, but makes it sound like a real 2-stroke, frees it up and the kids will love the sound. We are also changing the front sprocket down a few teeth to see if it will allow my son to get better throttle response. That's about all we have thought about so far and all has gone well. Good luck !
