1972 BSA A65L engine knock

[Zoltan]

Haven't seen a lot of BSA guys on here, but I thought It'd be worth a shot anyways.

Purchased a BSA in november for 'discount' due to some engine noise. The bike has a little over 2000 miles. Valve clearances are set correctly, oil is getting to the top end, nothing dangling around in there. Rockers appear to be assembled correctly. Thought I would post to some bike websites before I really dig into this engine, in hope that it is still something simple. \

smoke in video is oil burning from spitting out of the - not completely tightened rocker cover -

thanks in advance for any suggestions!

all the twins(a7,a10,a65) have a bushed main on the rt side of the crank which does not hold up very well (neglected oil changes,old non detergent oils , etc) . You can check oil pressure or physically check movement by removing the right hand cases.
You should get your self a good manual and check out britbike.com forum..
good luck , joe
