Hi all
For months now I’ve been trying to tweak my 550 carbs I now have new carbs air filter and still have the same problem my spark plugs 1&4 are always rich (black) and 3&4 weak to normal (light brown) this makes me think ignition, I think I have a David silver electronic ignition as when I set the timing on 1&4 there is no adjustment for 2&3
The bike sometimes takes a little while to start then hesitant to pull away but runs great at higher speeds I have changed carbs, filters coils and plugs each time we get better but the plugs are always the same.
The bike used to overheat and oil warning light would come on at low revs and tick over would drop
Any ideas before I change the electronic ignition
Thanks
