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.

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.

Did you get sorted?  I recently got some from Raybox engineering in the UK.  These are manufactured from high tensile steel with 'rolled' threads, not die cut.  Shorter than what you want but maybe contact them.

I found out the hard way that the studs I bought previously were made of some kind of cheese, the moment I tried to torque them down.

I received some bits off him, a lady dealt with me, last week. I put a watch on the studs 8.8 high tensile, rolled threads as you say Egbert. Can`t muck about with cylinder studs. Proper job.

Fit decent plain washers and springs and quality nuts too. He sells the 8.8 tensile nuts... ** Please log in to view **?

I don`t like spending money on new stuff, but this is one of those areas I don`t compromise. They`ll outlast everyone.
