Are these rebuild kits pretty good or should I stay oem at least for cylinder and head?

How did it go? I can’t get my kids pw to run hardly at all, just did a new oem carb, thinking about doing a rebuild

Do you recommend honing the cylinder with a flex-hone to get a cross-hatching before installing?

@julianstrau8355 Жыл бұрын

Does anybody know if this cylinder or engine also fits the Yamaha Sting SG 50? It looks so familiar.

*Get some decent footpegs for them. *The OEM bars restrict the options for levers so going to the hassle of converting to aftermarket bars can be worth it as it allows you to fit reach adjustable levers. Keep an eye on head stem bearings and races and consider upgrading as the OEM races are prone to cracking. *You will need a dual gauge to confirm the oil pump is set correctly. *The suspension is garbage so be prepared to spend time maximising its ability once the child starts to find its limitations, which will not take long. The 2017+ pw50 has upgraded forks and are a wise upgrade to any older pw50.

blz I'm from Brazil I have a bike like this and the start pedal stuck what could have happened

@carlosnoevalle4037 2 жыл бұрын

I had the same issue, I just open my pw50 and the kick shaft was broke inside , just remove the engine cover where you put the oil and you going to be able to see the broken shaft , I hope this helps you.

What psi of compression should these pw's be at?

@rmatvmc 4 ай бұрын

100-115 psi is great. If you're in the 80-100 range or less, you'll want to do a top end.

@iuliangoicea7667 Жыл бұрын
