1) the reason when you buy bearings from pro flo that the numbers are ground off and they come in a plastic bag is Bc that’s what he does for a living . He did the work to find them and know that information and if they were just floating around everyone would have them and there would be no reason to pay him .of course bearings aren’t all he does
2) interestingly enough the only people I’ve ever met trying to figure out these numbers have countless amounts of illegal mods. If you’re running your pdub with the torpedo out of the exhaust, wiseco piston, no oil Injection, pax transmission gear , HD clutch springs , holes in your air box, etc . Bearings aren’t gonna do shit for you because the first AQ you show up to you’re gonna have a line of people tearing you down before you go out for your first moto . not worth it .
And it was years ago, but I went in to Ponca in '79 at 15 as the #1 qualifier from the west in 125 expert, I know the routine. I also know how wrong it can go, as I left Ponca that year with a torn ACL.
80 Expert at WMGP... Photo below is dicing with Chris Heisser. Scott Burnworth won that 80 mod class.
So it's still years out, but if he wants to ride, I am on 1.5 acres and can turn the pit bike loop in to a practice track in nothing flat...
Because I said I could afford a Pro Flow?? Not sure where you are going with your comment.
Moto Dad's (or Grandad's) can give the kid a great experience without being a bitch.
With a simple Google search I found the bearing brand.
Once you pull the factory bearings all you have to do is go to a bearing house that distributes that brand of bearing.
Not sure why the moto 3 start was bad for him, but I don’t remember any protests that year. Those 2 were just on a different skill level at the time. Thinking back, i haven’t heard either of their names since that day.
Stopped by Barrs Competition last year and they were building about 30-40 “legal stock” PW50’s and they have been building them for Lorettas champions for about 40 years.
I just bought a Pro Flo bike, made my decision easy
Pit Row
I understand some people above thinking that money spent on a PW50 is wasteful... But even a decent mom and pop racing program will include proper maintenance and race prep on a race bike. We would go through 4 YZ80's a year since we raced and practiced on the same bikes and there were multiple stock and mod classes. I think today the better route is a practice bike and a race bike or bikes. And if planning and prepping for a LL run, a premium built race bike isn't unreasonable, even in the shaft class.
Talent is still king, but practice, training and talent supported with a proper race bike is simply doing your best, no matter who you are. Am I missing something?
1. You are allowed to use aftermarket bearings as long as they are the same class and fit as the stock bearings.
2. If a bearing has any identifying markings ground off, they will be deemed to be illegal.
3. NO chamfering of any ports is allowed in the PW50 class. The only time chamfering has ever been legal is in the replating process. I'm pretty sure the PW50 is not a plated cylinder thus no chamfering allowed.
Hope this helps. Please send any further questions to

I can't remember who said this but no one has ever put it better:
"Don't mod the bike, mod the kid!"
And before anyone complains, this is not a reference to Performance Enhancing Drugs.
Fuck it, I'll get some of these bearings. Maybe his younger sister will take an interest in it.
