Aye Chrissie,
All the previous and a small flexible rubber mudflap extension to the front mudgaurd. Even with the oil cooler, an NGK sealed plug cap, deflector for the coil and lashings of WD40, the flood from the front wheel can bring the sparks to a halt.
Also, if and when laundering the bike, make sure you flush all the crud out from around the plug area. 'Gert' my first SRX600 had the plug corroded into the head and it had to be dug out!
Keep boppin', Bill
