Just checked the valves on my 390 today. To my shame I realised I'd not checked them for about 160 hours. To the bikes credit, they were all still in spec with both inlets at 0.12mm and both exhausts at 0.15mm. Bike's now on 304 hours and 7807 miles.
Whilst looking for the valve clearances online, I came across a thread that mentioned timing marks? I'd already found TDC by sticking a straw down the plug hole after the inlet valve had closed and rotating the rear wheel whilst letting the piston push the straw upwards through my fingers but I still can't see the timing marks referred to online - anyone able to point me in the right direction, preferably with a photo?
Thanks
Steve
