I've tried the 10mm spark plug socket but no use! also I've take all body work off the tank to reach the vertical plug but I'm still struggling to reach it, do you have to completely remove the tank? If so what's the best way don't fancy fuel everywhere! thanks for any advise on this.... Steve
You may not have to take the tank right off but you'll need to unbolt it and lift the back end and also release the fuel pump connector. The plug is 10mm with a 14mm hex: MAR9A-J specifications
OK many thanks I've just checked the front one but can see the difficulties with the vertical one will give it a try now.....
