O.K so went to the bike & didn't start - assumed I may have flooded it (smell of petrol) so pulled out the plug and at the same time as I move the plug boot it came off - copper thread inside very Green
So given the lead is already short and hope no to cut it - which NGK boot are you guy's using > have seen it mentioned before - i.e dump the crap metal one and replace with NGK......... but can't remember angle etc (I assume it will be deep set one) and model number would be great. What pisses me off is the I had 2 from the Guzzi engine I am using i the trike - but cut one trying to make it fit in CERY tight chassis, and the other fell apart!!!!
Thanks
