Stock?

My bike is completely stock. Before the rejet it took several minutes to warm up, even in the 80's. For the first few minutes the throttle was touchy, not smooth, and even when you could turn the choke fully off if you tried to give it some gas it would stall.

After the rejet, I fire it up with maybe half choke. Usually I can turn the choke off in 30 seconds or so and ride away, throttle is reasonably smooth (still takes a block or two to really smooth out) and no stalling.

Overall I'd say it was worth it. You could skip it and still take off right away, you just have to keep the choke on and deal with the jerky throttle response for a few minutes. Overall though it was pretty easy and only cost $20 for the jets, so I'm glad I did it.

Ive never had to use the choke on my bike ever
