Ok....so I brought the bike out of the garage for a spruce up before the summer, as the weather has been looking more promising...
I decided to put some new plugs in, change the oil and check the timing ( not done that bit since I don't know when).
Now, here's the conundrum, the strobe light shows that the timing is about 4 degrees or so retarded, but the mounting plate doesn't have any more movement to adjust for this....any one else seen this problem??
Was considering splitting the mounting holes round some more, but the bike runs absolutely fine, and start.s on the button, even after 4 months inactivity.
Any advice or thoughts??

Thanks Bob

For me ..leave well alone, timing dosen't go off unless there is an issue elsewhere. If it runs fine and more importantly starts ok ..out of timing ..it wouldn't
The markings on casing etc aren't always precise even if they are meant to be ...no one would follow the chain adjusters would they?

That was sort of my feelings... I'll leave it be, but was curious why so far out..
Anyway, the rest of the bike is looking ok...
