Hi Dar,
I only converted those Metric figures on the Webra site to Imperial. Having been eductaed (?) in England during the '70s & '80s I am bi-lingual... sort of... when it comes to dimensional units.

Spooky that you should post now ... I have just printed out your 17 page thread - "Tapered Bore Engine Break In" - as I have a Webra 50 & an MVVS 49 that both need running-in and I want to try and do it properly. Thanks for the info btw [sm=thumbup.gif]

Spring is here
