Vader Big Bore Kit

Themanoz · 05-15-2018, 01:18 AM

Hey guys, I've been using this site as a reference for a while now. Finally decided to join in on the fun! So I have a Vader/Baodiao 125cc grom clone. I have been doing some work on it here and there, mainly power upgrades to keep up with traffic in busy Southern California aka 60 mph comfortably. So far, I have installed the mikuni 26mm carb, 17t front sprocket, and aftermarket exhaust w/ gutted cat. Top speed was 60 mph exactly so far! Now I'm looking for a big bore kit as a next step.

Here are my 2 options that I have found:

So my question is: what is the wrist pin diameter on these engines? My research hasn't given solid results. The 141cc bore requires a 14mm pin and the 146cc bore requires a 13mm pin. Do you guys think it would be possible to fit a 14mm piston with the 146cc kit? On another site, it says the 146cc kit has a 14mm option (https://tboltusa.com/store/tbparts-r...ines-p-55.html)

On a separate note, would this cam fit in the head?

I know this is long, just need some input! Thanks guys.
