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.
