My son jumped his pw 50 off a pile of dirt going down a hill. Almost endoed. Bent the forks. Ended up busting up the spark plug boot due to the front tire hitting and knocking it off. Ordered new forks and spark plug boot and wire from pw’s only. Fork tubes were to small and had slack in the lower triple clamps. May have sent the wrong ones I dunno. But they didn’t work. So now I need a source for actual forks that will fit. I assumed the spark plug wire would just be a easy swap. I’m guessing now that the stock ignition coil and wire are made as one piece. I couldnt get it loose. Any advice on replacing the spark plug wire or do I need to replace the ignition coil to make it work. Thanks in advance for the help

I will not claim to be an expert on your PW50, but in most cases the plug wire is made in the coil and not replaceable as a separate item. However the cap does unscrew and is replaceable as a separate unit.
With the coil assemble only costing about $25, it would be good to just replace it.

NGK makes a splice kit for plug wires. Very easy to repair or lengthen the lead with one of them. Used to have a ton of PW stuff. Down to the last one now.

Looks like those after market forks offered today are about a MM or so undersized from stock. For that, just go buy some shim stock, and fit a small piece in as much of a wrap as possible. The top leg nuts are what keeps them most secured. Those things are not worth dumping much money into, so cheap it out if you can.

Better check the lower steering head bearing race. Most all of them crack. Will egg out the frame tube if not fixed.

Screw it man, just cut some strips from that last tall boy can and jam that shit in there.

These forks were about 1/2” smaller on the fork tubes. Everything about them was smaller. May try my luck on another aftermarket set before blowing money in oem. I will definitely take a look at the lower steering head race

My opinion is you should get your kid the right (OEM) stuff not cheap Chinese knock off crap. Sucks he bent the forks but you can get a set from Yamaha for around $200 and they are the right ones

Yes. Or get some calipers and measure the old tubes. Most of the listings for the aftermarket stuff shows them to be about 1.2mm under OEM. To have a 1/2 inch of slop on a 22.30mm leg is pretty drastic. The legs are not even an inch O.D.. The replacements must be the size of pencils if his measurements are close.

I remember Cannon Race craft offered a set of hardened tubes at one time. At least with the beer can shims, the material will match those knockoff fork legs.

PW80 front end with a 10 inch rim spoked up was common at one time.

Pretty sure I’ll be ordering oem tonight. Half inch may have been a little drastic but it would definitely take more than a small shim

I found some 1" cups from a bmx bike that fit . Held up a bit better. Chances are, you are going to have to shim the bearing cup as the frame is probably shroomed out, and won't hold the race.

Dunno why my edit didn’t work. It’s a 2020 model he rode about 2-3 minutes after the forks bent and kept knocking the plug boot off. Hopefully the frame isn’t shroomed out. Looks like the 2013 and up forks are actually different. All the aftermarket ones are for the pre 13’s

Well I got new forks from peewee cycles and they are identical to stock. Highly recommend them. I also replaced the steering stem bearings. The top race was also cracked. Something still doesn’t look right. I’m assuming the upper or lower triple clamps are bent. Is that common? About to take it all back apart and check them out. If they are bent do y’all think it will be okay to ride like that over the weekend till I can get a new set in?

Anyone had any luck straightening the frame back? Really want to keep the vin due to the last three numbers are a old racing number. Thought it was pretty cool. Also any advice on things that won’t be obvious about tearing it all down and back together? Sucks it’s only 2 months old.

Can pretty much leave the engine , drive line, and rear wheel intact when removing the frame. Some type of jig or table is going to be needed. Measurements from a non damaged frame to get the neck angle right. Gusseting is advised after repair.

Hang the frame on a wall. It’s a trophy now. You spent the money on oem forks, do what’s right and replace the frame.

I heard cooper Webb saying he bent like 8 frames on his PW. Tell your son that if he feels bad at all or anything.

Hell, my kid just ran his PW in to the barn wire fence at full throttle about 10 mins ago.
