Thanks! That manual is great!

Just filles out the 2 small holes in the top of the up/down sliding throttle valve in the carburetor. LORD HAVE MERCY ON THEM REAR TYRES FROM NOW ON

It was CRAZY restricted in the carburetor.. now it flies but i need to downjet a bit. I’ve found out that it is a Mikuni PD42J model carb (same as Yamaha YFM660 etc.) Where to buy main jets for this carb? Can’t find ANYTHING in my country?

is it just a regular 5mm main jet? Can’t find any info on that either?!

and do you know if this bike uses the same oil in gearbox and oil reservoir/motor? Or does it need gearbox oil in one spot and motoroil somewhere else? Never really worked on 4 strokes, only inline fours in cars 🤷🏼‍♂️🤷🏼‍♂️
