As above, but there is a BUT.
The 250's and 350's are stamped the same but are different!

Have a look at Xaviers web page as follows:

www.rd350lc.net/pageEXHAUST.htm

this explains the differences.

German restricted pipes then.
Check your carb refs too, if they also marked 4L2 then they are restricted too.

if your oil light is flickering when you brake i would put some more 2t in the oil tank .

You can take the restricting bits out the exhausts if you cut and weld them back up, 4L2 carbs would just want 4L1 spec jetting to bring them to un-restricted spec, not a big deal.

And yes put some oil in the oil tank.

Hi mate no on the carbs it has 4l1 there ok then are they

Yes should be provided fitted with correct internals, so most likely if someone went to the trouble of switching the carbs.
