High quality made camshaft to suit the BSA A7 and A10 swingarm models, this is a high lift sports camshaft profile and is suitable for use with high compression engines and for tuned engines, was popular for the A7SS, Super Rocket and Rocket Gold Star engines.
Can be used in low compression engines and plunger models, please see technical info below.
When fitting new camshafts and followers , cover with cam assembly lube; always check fitted valve spring length, most camshaft and follower failures are caused by over stressed valve springs .
Check fitted valve spring outer length to be no less than 1.400 inch (35.5mm) also check valve springs at full lift and make sure they are not coil bound and can be compressed at least another 0.080 inch (2.0mm).
When fitting the Spitfire profile camshaft to plunger engine casings, the camshaft trough may have to be relieved, as the cam lobes may touch the casings, it is not an issue on the swingarm crankcasings.
