Hi Tootall Paul,
taken me a long time to get round to seeing this, ok to use the picture in the section survey? Where are you going to put the oil, battery etc, If you need a pattern for making an underseat tank I can lend you a card and wooden version to modify. Mine has a rear head fitted, to the rear... so the oil tank will need relieveing ont'utha side. Finished in time for Mallory this year?
Best of luck and cheers
