Ihave always filled the remote filter with oil before fitting on both my bikes A7 and A65 and never had any problems, been doing it now for atleast 10 years.

Now would be a good time to check for wet sumping having been laid up for 2-3 months you will be able to judge by the amount of oil that comes out as Julien says there should be about 100mls if it is there is say 300mls then you have wet sumping and I would suggest you start the bike up at least every 2 to 3 weeks and you should have no problems. I have an A7 and an A65 the A7 doea wet sump but if I start it up every 2 to 3 weeks no problems the A65 does not wet sump even left for 2 to 3 months. Also wet sumping is only minor problem in the winter as the bike gets used in the summer.

I fitted indictors to my early A65 and the flasher relay emits quite a loud noise which is in time to the flashing indicators and you can't fail to hear it so I never miss turning them off after a turn.

Going back to the original post, if money is not a problem there are companies that advertise in the classic magazines who restore tanks back to original new condition but they are expensive the last I heard was that to take out dents rechrome and repaint you are looking at a cost in excess of £500 depending on amount of work required. I mtself on my A65 have an Indian made tank fitted but it did not come without problems nothing major but did require some work. The center hle for fiting the tank was slightly out of position so I had to realigm the chrome strips the hole itself was too tight afit so had to be ground slightly bigger  . The holes for fixing the knee grips were in the wrong position so I had to modify them tofit. The petrol tap bosses were in the wrong position they were in the position for twin carb models not my single carb model so had to make new petrol pipes to suit. I also had to respray the tank as I could not get one the correct colour, but the tank has been on the bike now for about 3 years with no other problems. I di seal it with POR15 which I can recommend.

I do use a head torch I find it works great for me  mine has 2 settings one brighter than the other and it shines directly on what I am looking at ,it is also rechargeable with a USB cable and lasts for about 3 hours it cost me £7.99 at a local sports shop. I also have a couple magnetic battery powered torches and a mains powered portable light but they are sometimes awkward to position exactly. where you want them to light  something.

As you did not give engine and frame numbers in your original post And you were not sure if it was a Super Rocket also it has not got an alloy head and it has a non standard tls brake I assumed you were trying to identify exactly what you have and the only positive way to do that is to do as I indicated.

I use a company called METAL SUPERMARKETS they have branches in various parts of the country they stock all kinds of metal and will cut to size. I was at my local branch this morning I usually ask to look at their offcuts rack and then pick what I want and pay at the desk, they are cheaper than ebay.
