Suzuki DR header welds – DRZ250 – DRZ400 – DR650

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.

Did it make a noticeable difference?March 18, 2017 at 10:32 pm #17289
On the 650 I did multiple mods at once so couldn’t tell. I haven’t ridden the 250 yet.April 20, 2017 at 9:18 am #17730

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 shortlyApril 20, 2017 at 11:24 am #17731
We actually just sold the Djebel, it had a slider carb.
