New member from UK looking for some help with the following issue,
My bike has just over 15 k miles on it and I've owned for a couple of months. Bike was completely stock when bought apart from PC 111.
I have fitted Yoshi RS3 and K&Ns, PC remapped to suit.
She was running fine then fired up one morning and running rough as hell, obviously down a cylinder but when I checked the headers for heat, cyls 1 & 2 were cold, 3 & 4 hot (reading left to right when sat on bike)
I have done following to rectify with no success
All for plugs changed (NGK iridium)
All coil sticks changed (Brand new Denso)
Tip best tool for plug change is the stock plug spanner from the tool kit which I didn't have
kit is same as versys 650, nice new kit off eBay for £17
Disconnected PC 111 and back to stock
Checked all electrical connections around plugs/ injectors
Cleaned fuel filter and fuel lines from tank and checked fuel pump all clear and fuel flowing.
Checked battery, looks to be very recent Yuasa and full of charge (trickle charged)
Before I remove throttle bodies to take out injectors, any ideas at what else to check would be very welcome!
