2023 Vader 150 Front Sprocket Help!
 

Hello! First post and first chinese ride! I recently tried to upgrade my stock 428-15tooth front sprocket with a 428-17tooth front sprocket but the center shaft size on the new 17t sprocket was too small to fit on the shaft. Anyone know what size center I would need on a 17t? I guess i just ordered one i saw someone put on their 125cc. Are they not the same size?

Make sure you get the 20mm shaft.

13-17T fits without any modification, just plug and play.

For an 18T, you'll need to grind a little off of the top left of the sprocket cover (near the starter motor).

For a 19T, you'll need to grind off the left 1/4in of the sprocket cover, and a bit on the engine case.

A 20T doesn't fit without major case grinding, and welding.

Thanks!
 

Also if you dont mind! What length chain comes stock on our bikes? and will a new carbeurator for a 125cc fit onto the 150. I bought some things thinking that the vader in the video was a 150 lol. Appreciate it!

If you get the 150, there's no need to swap out the chain. It's a decent chain. You can use the OEM chain all the way from a 13t to a 19t front with OEM rear, or a 30 to 38t with OEM front.
