So me and Jetblack are at brands with my race bike and we have a problem,
It's firing on the front 2 cylinder onlys.
We've had the plugs out a lot and they are definitely getting fuel and spark.
We've changed the rear coil pack.
Had the carbs apart and cleaned crap out the jets.
It's ran before with these settings but the rear are 122 Mains, someone else suggested the rear smell like they're getting too much fuel, now we could of stuffed the plugs or/and the jets are too big?
What are we missing?

If you reply please quote the post so my phone buzzes. We've got no access to fresh plugs unless someone has some near brands, I've phones round the dealers, tried the paddock suppliers and announced on the paddock tannoy pleading for some.

Can the connections on the coil be pack to front?

Phone me REMOVED if you can offer any help at all.
Thanks
Ben

Bt late as im just on my way out in the opposite direction to brands but if you or someone can get to chatham i can leave some plugs out for you

Think we are calling it a day thanks Tony. Can't guarantee its spark plugs, both of us knackered and still a lot to do once the bike is running.

swap the front and rear plugs over and you will soon see if it is the plugs or not.

the coils can be wired either way.

If you have been using ER10s then that is going to be it.

I had a shitty day at Oulton park a while back with my racebike and it just did not like the ER10s. ER9s for the win.
