So, I snapped my return throttle cable over a year ago and have been running pull only cable. No problems. I have the Red needle and re-jet with 3x3 and aftermarket pipe. Everything was working fine till I went for a little spin around the block yesterday and when I let off the throttle to shift, there is a big delay. (i.e. the engine seems to rev longer than before) I am at sea level and its about 45 degrees out. Do I need to switch up to the Blue needle?
