A friend is looking at a 66 BSA chopper. The owner says the gear oil onto the chain and was told the cases will need to be split to fix this oil seal. But the owner is not very mechanically oriented and knows nothing about his bike. We haven't had a chance to look at it to determine. My question is if it is the main seal or gearbox seal can't they be replaced by pulling off the inner primary cover and or timing side cover? Thanks.
