We are building a Bantam racer. Now we have a Todd Head and cilinder to fit the early D7 crankcases.

But we need longer cilinder holding down studs (app. 160 mm length).

Anyone know where to get them? Not much available over here in the Netherlands.dunno

Hi, you may find it easier to make them yourselves. Take some steel rod, cut to length you need and use a die (or lathe if you have one) to cut the threads on the ends.

1956 D3 running, lights to sort. 7 other bikes in the Barn. 1950 D1 engine now running.

Hi, Good idea cocorico but make sure you get you have the correct grade of steel. The B175 studs were EN 15 or EN 16 - that's from my parts book.

(BSA must have been in a real mess when they produced the parts book - 2 studs quoted as EN15 and 2 as EN 16 - strange, oh so strange, and both pairs the same dimensions and thread sizes)

B175, on the road. Honda XBR 500, and ....... Suzuki Burgman 200 scoot! Nicknamed "The hair dryer" - by me I hasten to add; & great storage under the seat when you get to your destination.
