Post by Rockerbri »

how we first got her.jpg
Hi all ive been building a g2csr for the last 2 and a bit years i got it as a engine and frame the rest of the bike ive found on e-bay auto bike jumbles etc as you can see she was in a bad way but hay did not want to see it not put back on the road again any ways i canot find the correct bolt pattern for the bolts that hang the front mudguard i thought it was bsf so any ideas ? o the photos show where i started and where im at now she is running like a dream now so not far of getting her back on the road.

Hi

Some transformation 8-)

The threads in the heavyweight sliders are 5/16" BSF.

Nothing to do with threads types but please put the front wheel in the correct way round! The brake torque arm must be fitted in tension not compression when the brake is applied. It maybe that you already know this and have merely put the wheel in just to move it around but I thought I'd give you the heads up just in case.

Really, Rob? It would be in tension under braking when going ahead as the torque arm is in front of the slider.. Here's a pic of a G2CSR, taken at the factory, the 'wrong' way round..........

Different hub Nev. The picture you posted is of a British Hub type but the one in the original picture showing the after look is of the AMC hub which shows the torque arm attachment behind the slider. That hub is not from a CSR, but the very top picture showing the before look does have the later hub so something has been changed.

Cuh! Shows how little I know about Lightweights and post '57 bikes in general. "British hub.......AMC hub". Thank goodness the factory closed or we'd be 'avin a Brexit hub next :roll:

The brake plate and stay are on the right/offside on the 250 CSR ( the one with the air scoop slots ) but the 350 and the earlier lightweights have them on the left/nearside.
