Although this might be a possibility but very rare as there is an oil filter to trap the moving sludge/plaque which it does not allow to reach up to the rocker oil feed pipes. Also a motorcycle which is used frequently and in case of BOV's Bullet it recently underwent a rebuild, sludge formation can be ruled out. That the mechanic would've missed it during the rebuild would be a different story. Quote:

What a coincidence mate same thing same behaviour was on my 1969 Standard Bullet. The timing case cover as well as the bolts that hold it was having oil leaks. Although this was due to the worn out timing case cover as well as the holes where the bolts go had increased in diameter due to lashes of time. Luckily my mechanic had an old model spare timing case cover in good condition which was a perfect match. Nevertheless I got the oil pump replaced along with the rocker oil feed pipe and the problem was resolved. In the process I also replaced the timing cover gasket and also fitted bolt gaskets on the timing cover for further protection. I think in your case too this is a double trouble i.e. a worn out timing case cover as well as a faulty oil pump. Try the method of replacing the timing case cover gasket along with the bolt gaskets to see if the leak stops. If not go for a new timing case cover. I believe your Bullet too is an old model, if I am not wrong. Quote:

The fact that oil is not reaching up to the rockers says that the oil pressure is not enough, of course there is pressure but not enough to circulate the oil up to the rockers. An oil pump is what pumps up the oil for circulation. Assume that the oil pump is like a heart which pumps blood up against the gravity to the rocker cover which is the brain. If blood does not reach the brain the person dies. Same is the case with an engine if oil does not circulate with pressure the engine will cease. Hence oil pump has to be replaced and rocker covers on top should be opened to check whether the oil is being circulated or not. Mere checking by removing the banjo bolts will not give a clear picture as to the pressure. Quote:

Mate mere checking by removing the banjo bolts will not give a clear picture as to the pressure. As I mentioned above remove the fuel tank to open the rocker cover and check the oil pressure by starting the engine. If you see the oil circulating up to the rockers easily then the pressure is fine. This is the best possible way to check whether there is enough pressure which is pushing the oil up for circulation.

On the other hand I took it to a rather well known mech ; he said that it requires a rebuild. Probably just jerkin me around. Its just been 7-8 months since I rebuilt her. Gotta get a second opinion on this.

The "well known" mech is trying to fleece you mate. If you are a DIY guy with proper tools then check the oil pressure for yourself after replacing the oil pump, if possible take the help of a mech to replace the oil pump.
