      Hello everyone, this is my first post about my very recently acquired MZ TS150 which i am hoping i can get on the road soon. My first question is about the inside of the fuel tank- the bike has been off the road for a while and the inside of the tank has some light (but noticeable) surface corrosion. i’m assuming that when there is regularly fuel/oil mix in the tank, this keeps the inside free of corrosion but before re-filling for the first time (for me) what is the best way of cleaning/ preparing? Any advice would be gratefully received. Many thanks in advance, John.

      Morning John, if you are just tidying up before you go then try a handful of nuts and short bolts in the tank with some fuel and give the whole thing a good shake! Try not to go too hard in the fuel tap area or you may damage the reserve pipe and filter.

      Thanks Andy, much appreciated. Is there any kind of permanent coating treatment that can be applied to the inside? A new fuel tap and filter seem to have been fitted to the tank- would it make sense to remove (and block the hole temporarily) before the nuts and bolts/ fuel treatment? Thanks again, really looking forward to getting out and about on my new (to me) bike!

      In the end i used clear distilled vinegar + nuts and bolts followed by water rinse, a wash through with bi-carb solution, dried with a hair drier and ran a bit of fuel/ engine oil mix into the tank and shook it about. Left the vinegar in for about a day, and boy did some rust and gunk come out! its still not perfect but its a huge improvement! 🙂

      Good afternoon John

      I have used a product called evaporust, as used by edd china’s YouTube channel on a land rover chassis.
      My experience of using it to remove rust from a toolkit was very successful.
      You can pour the contents back into the container afterwards and use again.
      As others have suggested having loads of small screws/rivets etc to gently agitate the surface works well
      Screw fix stock this

      Regards
      Julian

      Thanks Julian,

      The vinegar treatment got a lot of gunk out of the tank (it hadn’t been used for a while) and got me going but it will definitely need treatment going forward so many thanks for the tip- i will check out the youtube vids!
      Have been running through my list of jobs and now have the 150 running and had a couple of short (5-10 mile) trips out (between the showers) to see how things go- the carb needs some sorting and i now have a small drip of gearbox oil; i suspect the level check screw should have a aluminium washer behind it?

      Thanks again,

      John
