i have a dt200l.. i have done a few mods to it pipe and v-force 4 reeds transfers cleaned up standard carb no air box..it goes really well very happy..
how ever i also bought a 32 mm carb for it..i put this on and started to jet it in..at low speeds its great power is much improved and throttle response as well..it will pull cleanly through the rev range..BUT if i sit at 80-90kms per hr roll the throttle on..it will cut out all together..this is just as i start to get to the mid range throttle position. i have done plug chops but the color is like a brick red so does not really indicate or help..i have riched the clip postion as much as i can but no difference. i guess my over all question is ..does this sound like a drastically lean mid range scenario? i have never experienced this before
ps does not do it with stock 28mm carb.
thanks
