PW50 Rejet after Oil Injection Removal
Posted April 13, 2009 - 03:48 PM
Bike still has stock jets, but removed the oil injection. Now bike doesn't want to idle but it does run better with premix.
I have a 62.5, 65 and a 67.5 to try.

My experience from the PW80 is the most power to be gained is from limiting exhaust restriction and correct jetting and you'll swear you got a whole new machine.

What did you do to remove the oil injection? Some guys say to leave everything hooked up, and just run premixed gas in the oil jug. Is that safe? Could it eventually trash the pump, or no?
You can remove the pump and take the pump drive gear off the shaft. Then the pump just acts as a plug in the hole.

The top end rebuild gave it a lot more power!

This will make the pilot jet lean condition worse. You can try richening the idle fuel screw, but it may not be enough.

I also put in the Holeshot clutch springs but my daughter doesn't like it that way as she has to keep it rev'd up to keep the clutch engaged.

In the near future (two weeks?) I'll have a better low cost silencer mod that doesn't destroy the factory parts, it should work on any of the 2t kiddie bikes, cost is around $10 and about 45 minutes of work, compared to the after market silencers that are going to be $80-100 and a half-hours work.
You can put lighter springs in and it will engage sooner than stock. But not too light or it may be engaged at idle. Your daughter may prefer that.
