I was just wondering what eveyone has done for mods and any instructions to do them would be appreciated. It's my understanding that the airbox on the 750's need attention as does the exhaust. Mine is pretty close to stock mechanically, but has a custom pipe and the can from a DRZ 400 and although extremely quiet, it's running very rich and doesn't seem as powerful as it should. I have a hard time pulling more than 145 km/h and is seems sluggish after 120. Do I need to completely remove the airbox and go with k&n's and a rejet and if so what size jets? Or is there some airbox mods or a different box that will work? I will remake the spark arrestor from the DRZ can so I can get more flow out of it.
