Thanks motomike....most of the riding we do is trail/desert riding. ie no MX tracks etc.
Its also worth noting that I had this bike for 3 years then sold it to a co worker, who then sold it to someone else, and then I recently bought it back (5 year gap), so in all honesty I dont know how they rode it, or if the bike was parked up. I did an oil and filter change when I bought it back, as well as checked the air filter, which was brand new so clearly the PO serviced it.
