    I think your being paranoid but be interesting to know if they did need adjusting?
    Never done mine or even thought about them.

    Steve just done mine at about 280 hrs mine were on the looser side of the tolerance which is better than being too tight only done it because she started to smoke

    I'm sure you ride the older Ktm RFS?

    Easiest bike to adjust valves, they are on adjustable tappets no shims required.
    I've had two Ktm 450's and a 400, all RFS engine. Engine is easier to start with correct clearance and power increase. My 400 cut out up Walters and wouldn't start due to clearances.

    No its the 2012 onwards engine. Its no smoking as far as I know and easy enough to start so I,l leave it alone.
    I was thinking of fitting a new piston kit at 250 hours.
