I don't have my data on the 2002 available. If you look at the carb and their is a round vaccume module mounted to the side with three vac lines attached...two to the carb and one to the intake manifold then the answer is yes you have one. If the side of the carb is clean and you can read the Kehin name on the carb you don't.

Brian are you there?
Could I direct this question to you?: What effect does disconnecting the gray wire do?
I’m curious on your opinion of disconnecting it.

I have none of the fancy jetting mods save richening mj, stock needle one notch richer, and one richer on pj. That's it. Runs great, maybe not as strong as some with custom needle and BK mod, but doesn't foul plugs, and virtually no cough. I can ride from 2000 ft to 7000+ and it's fine. I am on the second plug after about 3000 miles, and no complaints. Am I lucky, or are we over-thinking the mods?

Maybe yes and no. Until some insider from YAMAHA provides some answers…
There’s got to be a way to check what happens. Has anyone tried this: Set the bike up on a dyno, wire in toggle switch on the grey wire and note the difference with a timing light as the switch is toggled?
Or, what about just get the YZ ignition module?
Does cutting the gray wire on a WR cause noticeable pre-ignition (pinging) that was never noticed before?

I am certain that Taffy's jetting tips are the ticket for pure performance. Many people here on TT have done these and all seem to like the effect. My question is this: do the bikes then become more altitude sensitive as a result? Does it require re-jetting every few thousand feet? If I ride one week at 2000 ft and then next week at 7000, will I likely need to rejet?
What do you think, TAFF?
