| You know I’ve been thinking about the crank plug backing out and can’t understand why this would happen, is it the material used? I mean we are not talking about state of the art technology here crank plugs have been used in cranks for as long as cranks have had an end feed for the big ends, and it cant be the vibration that causes it because you can't get much more vibration than in a British parallel twin, so it must be a design fault and a pretty basic one really. On a British twin it is a steel plug that is staked in, and I’ve never heard of one these backing out.
Any one care to put me right on my theory? |
