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.
Sounds like your Choke could be stuck on,it may be sticking in the carb body.
Your peformance is way below par, it should pull like crazy to 135-140kph then climb up to 155- 160kph eventually getting to 165- 170 kph if you have enough straight road,or more with mods as mentioned above
