Re: Houston ....we have a problem ...

Are you possibly trying to fix a "150" inlet to a "200" inlet manifold stud spacing? The two inlets have different stud spacing dependant on original cc- the "150" type studs are closer together than "200" type. not sure what you are talking about now ..........

Re: Houston ....we have a problem ...

The pictures not brilliant but that appears to be a normal larger engine mount- there appears to be the remnants of the usual white paint thereon. Innocenti produced two engine mounting systems- all S3 LI models and anything before used the short bar with the engine mount totally enclosed within the...

Re: Houston ....we have a problem ...

thanks Mick- thats the thought I'm coming round to. In over 50 years of scootering its never happened before but I suppose there's always a first time.
