I recently bought my son a new Pw50, he’s 5 and only been riding for a little over a month. He’s picked up riding very quickly and is already topping his Pw out around the local tracks. I’m looking for some tips to make it a bit quicker and have a little more throttle response (Gasket and screw have been removed). I DO NOT WANT TO MOD IT. He wants to race the stock 4-6 shaft drive class. Just trying to by some time and save money for a KTM or Cobra 50. Thanks!

Dont think there is mutch to do on thoes bikes other than the gasket screw thing and i have herd of cutting the throttle cable down 2mm then running it like that
Maybe able to find a trade for a ktm or cobra because some dad bought it for there kid and he could not handel it
Also some dealers are giving pretty good discounts on left over 50s could trade the pw in the finance it
( i am fulley aganist financeing bikes, but i would do it for my kid.)

He’s still got some stuff to learn on the pw but it won’t be long before he’s ready to move up. I’ll probably just have to buy the KTM or Cobra..... I’ll probably buy new because I’ve seen how some people take care of their stuff and I don’t want someone’s mess.

A couple things to do is:
1. Getting the jetting right, I went down on the main on my Grandsons and also up one clip on the needle(lowering the needle).
2. Find a set of QT50 gears, this is the ring and pinion. They gear it down just enough it pulls from a dead stop so much better.
I know allot of guys send their engines to Barr's to get balanced and blueprinted. Another thing to make them faster is to look at tire weight, I can't remember off the top of my head but there is one set of tires most run to cut down on weight.

Keep him on the PW for a little bit longer and then throw him on a 65. Forget the KTM, Husky or Cobra 50's. Save the money for a 65. I went from a PW50 to a KX60 no problem.

Sending it to Bars or proflow is a good choice. For the full blown package you will spend the same amount as the bike costs but there is no comparison between those built bikes and stock.

I also heard about not using grease at the drive train at rear wheel only use a WD40 based lubricant for races only. Refresh before each ride

Barr's done a lot of thing to cut down friction through the drivetrain besides the tuning.
Take it to the limit, one more time!
