Edited Date/Time:
I recently bought a 2016 150 SX from a guy and rode it for the first time yesterday. On the second lap this happened [photo below]... the exhaust flange broke.
After further inspection I think this was broken previously and poorly repaired with something like JB Weld by the previous owner (he didn't say anything about it). I thought I lucked out because that piece bolts onto the cylinder which means I could buy just a new exhaust flange rather than a whole new cylinder but after looking at the microfiche on Rocky Mountain it doesn't show a part number for this piece. The only way you can buy it is by getting an entire cylinder & piston kit which is $850
Does anyone have any experience with this? Know how to get just the part I need? It is a seperately cast piece so why would KTM not sell it as its own part?
