#4 plug fouling....

[Seana23]

Hi all.
Ok, so.i think the carberation is roughly set up.for my GS850 with Harris 4-1 and pods...
But....
Number 4 cylinder keeps dying.and when i take the plug out, it doesn't spark when resting on the engine...
When I stick another one in, it fires up on all 4 again...
Then after some 10 miles or so, it goes back onto 3 cylinders...
Then 4 again with another (not even new) plug..
And so it goes....
What could be causing this?
Thanx all.

What colour is the plug? It's probably running rich and fouling. Have you still got those 'restrictor bands' on your pods?

Hi HH.
yes, ive still got my Patented Pod Socks on...
The plugs seem to be a healthy dark grey colour...
so you think its running too rich... Ok. Ill add that to the mix...

Thank you babes.

Got to fix a couple of bikes for other people before we go on holiday .....tomorrow! Camping with the missus and the kids 50 yards from a private beach. Jammy ain't we, picking the only week this summer with sun. 90+ degrees on Tuesday - we'll be in the sea, few lagers in a bucket, BBQ sizzling, beach cricket and I'm not too old to make sandcastles.

ok, quick update..
ive checked a few things....
the pod socks were covering the front half ov each pod and the needle height was set so the circlip was on the one down from the middle notch (4th groove down).
so yeah, the air is being restricted by approx 50% and the fuel is being richened at 1/4 to 3/4 throttle......
i changed the main jets the other day to 130's as i previously had 142.5's in there (because they were laying around in the workshop (back livingroom)
so once again your right, oh wise one from the West (admittidly not very far west but west none the less).
Right, so i spose i could either lower the needles or roll back the old Pod socks to only 10% or 20% coverage and see if that helps...

thank you.
Have a great wee holiday. hope the weather holds for you...

give my regards to Mrs HampshireHog.
