The reed block holes were there for the fuel pump,
as i've said all 3 motors ive got are ex-speedway so they have drilled and taped holes were they've needed them.
What i hated most is that all the steel collets that would other wise be in the swing arm pivot hole were removed leaving large open alloy holes.
Thats why i had to make the swing arm spacers i did.
Ive also had to track down 3 kick start mechanisms @ witch ive only got 1 but i still need the small pressed steel tab that stops it unwinding.
I'm hoping the 250 1 will work.
BOB: Yes they were push started in they're speedway life.
For your interest formula 5000 is based on say 1/2 scate sprint cars running 500cc single 2-strokes or 600cc single 4 stroke, they do go well.
They had a national rule change last year where the now run 600cc 4cyl late model jap bike motors.
