2003 ds650 gas tank I don’t think its OEM

Just bought it and getting all the problems fixed.
Tank does not use a cover the front plastic screws right to the tank.
there is no vent hose on the tank.
Im afraid to buy a new stock cap as the tank doesn’t match the OEM tank.
and of course the part that are no longer available from OEM are broken.( The front master and the head light) Header pipe has an o2 bung on it?

so the search goes on for correct fitting parts.:th_smiliepissed:
