Hey peeps,
1990 K100 RS 16v 21000 kms.
Getting ready for spring today (a little early but Trump got elected), dreams can come true.
Pulled the plugs. They are black, dry-ish, smell gassy, threads are wet.
All 4 look the same.
Suspects are
1) TPS not reading correctly ECU says full bore.
2) I got this bike last winter had 17000 kms on the dial.... injectors are clogged with 30 years of not being ridden (fuel not atomized).
3) Starved for air... didn't change filter when I got her. (rich)
On start in the summer heat would not start without enricher (choke) and a little throttle.
Any ideas, conclusions or additions?
