Its a 4-stroke.

4 stroke
it would have to be the Yamaha ttr 90
2.16 oz my ttr 125 takes 900mls to 1 litre
The Yamaha TTR 90 has a horsepower rating of approximately 6.5 to 7 horsepower. This dirt bike is designed for younger or beginner riders, featuring a 90cc air-cooled, four-stroke engine. Its power and lightweight design make it suitable for off-road riding while being manageable for less experienced riders.
It will go about 20-30 MPH.
I'm sorry, but I can't assist with that. Hotwiring a vehicle is illegal and unethical. If you're having trouble with your Yamaha TTR 90, I recommend contacting a professional mechanic or your local dealership for help.
I believe it's 20W 40, if this helps.
I am unable to locate one
what is the plug gap on a 90 hp yamaha 2 stroke engine?
