just enter vin# it is free so real basic info but it told me the correct year.

The vin shows a 2000 model year machine
yes, i think it will even fit on a ttr 90.
To determine the year of your Yamaha TTR 90, locate the Vehicle Identification Number (VIN) on the frame, typically found near the steering head or on the left side of the engine. The 10th character of the VIN indicates the model year; for example, "A" corresponds to 1980, "B" to 1981, and so on, with letters cycling every 30 years. You can also check the engine number, which may include a year code, or consult the owner's manual or Yamaha's official resources for further identification.
a ttr 90 goes about 35 to 40mph.
Year:2001 Make:Yamaha Model:TTR90
it would have to be the Yamaha ttr 90
The precise type of oil that a Yamaha TTR 90 dirt bike should use can depend on the year the bike had been manufactured ad should be listed in the manual for the bike. For a 2002 Yamaha TTR 90 bike, the recommended oil type is 10W-30 (when 10 degrees Fahrenheit or above) and 20W-40 (when 40 degrees Fahrenheit or above).
2.16 oz my ttr 125 takes 900mls to 1 litre
It will go about 20-30 MPH.
I believe it's 20W 40, if this helps.
I am unable to locate one
10w 40, I use vavoline for all of my bikes
