Why are my plugs all different colours?

[IBLOWN]

I've got an injector cleaner if you want to send them to me? can test and clean them out and send them straight back to you.
Your bike dosnt have an o2 sensor does it?

If no o2, vac lines are all clear, then I would be looking at injectors.

those plugs are way rich,
if the air cleaner is cleaned and theres no restrictions/blockages
anywhere in the air box and the injectors are fine
then you'll probably need to adjust your fuel maps.
maybe give it a dyno.

Its actually booked in for a PC V in the next few weeks but wanted to sort out this problem first.

It definately has a problem if the richness is getting worse over time. Tuning would be a waste of time until its fixed. The tune will just go out of whack again.

i dont wanna get caught up in any of the crap thats going on,
just had a cpl of thoughts

the other thing ive seen that can cause the plugs to foul can be
the coils, are they getting full voltage?
i thought i read where u stated the bike was running fine, i could be wrong, what makes u think its getting worse?
unless u had the plugs out prior and they looked fine you wouldnt really know unless the bike was losing power.
also once the plugs start fouling it will make the engine run worse eventually anyway, the plugs dont self clean once they start
fouling up, so maybe once u get the pcv put on and sorted ull probably find itll fix ur problems.

if u think the fuels could be causing the problems clean/replace ur plugs and fill with different grade fuel run the tank and
pull the plugs again and compare.


just saying.

I havent checked the coils voltage yet. I check their resistance and theyre fine. I'll check the voltage soon.

You could have a point there about the plugs building up with crap. Its getting worse because i can smell the exhaust more and its now burning my eyes. My trip computer is also showing this.
