    The DR650 is well known for having crap header welds where the flange that bolts to the head is welded to the header pipe. On my DR650 I took off about 3mm all the way round and that still left 2mm in place.

    Today I had to replace the Cam Chain Tensioner gasket on Jennifer’s DR250 Djebel, (Which is for sale) so I pulled the header off the 250 and found the 250 is exactly the same as the DR650.

    I managed to take the lumps on each side out but ran out of grinding discs for my dremel.

    So if the DR 250 is like this then I imagine the DRZ 400 is most likely to as well.

    Nice job.

    Did it make a noticeable difference?

    On the 650 I did multiple mods at once so couldn’t tell. I haven’t ridden the 250 yet.

    I did my DRZ250 offroad machine. It made a difference – not as mush as the subsiquent air box and DynoJet rejetting of the carb did.

    Has the DJebel a CV carb or a slider carb? I can recomend the jet kit to liven the perfomance somewhat.

    I will be looking at MY DRZ400’s pipe shortly

    We actually just sold the Djebel, it had a slider carb.
