The frame number you gave is incomplete.  It should be 17 digits.  Look for it on the steering head of the frame.  The tenth character (not the 7th or 8th) of the complete VIN will be 'Y' for a 2000, '1' for 2001, or '2' for '02.  The engine number can only be researched by someone at a Yamaha dealer.

The VIN may appear on another sticker on the bike somewhere, or on the title/registration papers.  All VIN's have been 17 digits for some time, although the coding in VIN numbers within the EU varies from the North American standards sometimes.  You may need to check with a local Yamaha dealer to figure this one out.

Long shot, and perhaps not definitive, but what's the number on the left side of the carb?

The carb is an '01.  If I had to guess, it looks like it is the first 6 digits that are missing from the VIN, that the "1" is the year marker, and the 7 digits after it are your sequential vehicle serial number.

:uk:  Old School British Thumper Technique: 

 

  1. Put the bike in gear and pull it BACK until compression stops it
  2. Return to neutral, pull in the compression release and hold it
  3. Push the bike to speed, shift into second and allow the engine to start turning over
  4. Ease off on the compression release, and gently roll open the throttle just over an idle
  5. When the engine catches, pull the clutch in to keep it running, and/or ride it.

Try increasing the pre-load on the rear spring.  But pre-load is correctly adjusted while you are sitting/standing on the bike, wearing full riding gear.   Lots of info on here about pre-load, sag and ride height.
