Hey Tonnyguy! welcome to the club. I just got my vader running good yesterday. The stock headlight bulbs draw to much and kill the battery. I replaced mine with these
https://www.amazon.com/gp/product/B00D6PJGJM/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Also my carb had the throttle screw backed way out, and made it so that my electric start wouldn't work and the bike wouldn't idle.
I think used wet clutch safe 10w-30 for oil. Change every 100 miles or so for the break in period.
Always use premium gas!
As for faster a lot of people are switching their carbs to a mikuni 26mm vm22.
Doing a sprocket change will get you a bit more in top speed, but slow your acceleration. 15t or 16t is common.

Vader 125cc

Ok thanks about that.

What I find out when look up online that
428 17t front sparked is the right one .

About the oil I understand that 10w 40 is the best you really think 10w30 will be better?

About the carburetor do I need to tune it and play with that or I can buy it and just replace it with the old one ?

What about the cylinder there is any cheap option about that ??

Cdi box not will make change ?


Thanks!!

Thanks,
I have installed a VM22 carb along with a 26mm intake manifold to my BOOM BD125. I have it pointing forward and it only requires slight modification to the plastic under the red frame.

For exhaust I went with the Aodonly Racing exhaust. It fits but you'll have the bend the pipe right under the engine at the 90 degree bend.
