Title: Am I running rich?
Post by: teecee90 on 21 March 2017, 09:22:49 pm

These plugs were fitted new last July about three months after getting Ivanised. The bike has done about 3000 miles since then.

Yes definitely rich, should be more a light tan colour,
First thing would be to check the air filter if this is ok then it would be best to Dyno it to see if the enrichment is across the range or different parts of the throttle openings
Then you can decide how to fix it, might be as simple as a pilot screw adjustment

New air filter (genuine Yamaha) was fitted at the same time as the plugs, so can't imagine that's the problem.
