Yes, I have these. https://yamahaxs650.com/product/headpipe-torque-inserts/Couple more questions....
Did you use torque cones at the engine flanges in this exhaust or no?
What sort of jetting did you go up to if you recall?
I also bought Exhaust Port Optimizers from 650 Central.
The engine is still on the bench. I will use BS34 carburetors breathing through stock airboxes. I'll start with stock jetting. That's the plan.
