...these are wonderful photos of the Perthshire Gask circuit. They give a flavour of the open countryside of Perthshire.
If you drive from on the A9 heading north toward Perth you will see a sign saying to the left 'Findo Gask' . The circuit was a WW2 airfield and is all now disappeared for housing and returned to farming.
 
 






I seem to be forced by circumstance to bore out the 350cc to be a 500cc.... the current set up is a long conrod which allows a triumph 650cc twin t120 piston . It has a compression height of about 26mm which is the same as a Honda 400 XR. Hence I am experimenting with the possibility of 85mm X 88mm giving the 500cc dimensions of BSA Gold Star . However I am very conscious that I do not have the breathing capabilities that machine has/had. However I am looking forward to the weekend of 12/13 August for the GB memorial sprint at East Kirkby. ...it has become a sprinters version of the Goodwood revival.

                                                      Trying a different exhaust system down in Lincolnshire .

I find the cylinder head on the old Norton can be difficult. Valve guides can work loose rather too easily for my liking.
 
The shape of the inlet port is poor though the exhaust seems far better in design.

Coming to the line at East Kirkby in September


 
Little knowing my piston would seize that day.

Had great day on Sunday 11 Sept at East Kirkby which is near Skegness . Great machines from the golden days of sprinting were there including ones borrowed from museums.

Rather well restored and prepared 175cc MV Agusta at Kirkbride last month.

 
Please my bike got a mention in the National Sprint Association magazine. The last outing- last month at Kirkbride- with points and battery !! Now using BTH electronic magneto and won't look back to my days of misfires.
