One for the mechanical genii on here…
I have a 2001 Honda Blackbird, the fool injected one. It’s very low miles (8k) and was last fully serviced 500 miles ago (but a couple of years).
I took it in for its MOT today after being garaged for the winter. It was really lumpy under 2k revs to the point it feels like it’s running on 2 or 3. It clears above 2.5k and is fully normal up to the red line. It had a small amount of fuel in from last year so I brimmed to with Super Juice, had a long ish ride and gave it an Italian tune with zero effect.
Google says fool regulator or O² sensor, though if the latter, it would be throwing out a fault code which it’s not.
What do the wise mechanical wizards of STW recon? ‘Buy a new one’ is not an acceptable answer according to Mrs Boblo 😉
