Hi guys, another small problem with my bike. When warming bike up, the choke is really touchy. I mean if I turned it up full, it would rev at 4000 or so and then I have to bring it to about 1/2 way to get it to sit at around 2000 (what I would think should be normal ?) and then it sort of revs higher then lower then it may go all they way upto 4000 without me touching it. So this being said, is this just a simple choke adjustment, or could this lead to a more serious problem?
