Went for my first major ride of the season and the 1998 srx700 had a few minor problems. Hope someone here has some suggestions on were to look. First, I clean my carbs at the beginning of each season (I actually have two identical carb racks so I can clean one at my convenience and quickly swap them out when the time comes). Although, I cleaned my carbs at the beginning of this season I had a issue today that I think might be carb related.
Right away the sled was hard to start. It is stored in a garage that is kept at 65 degrees fahrenheit. It usually starts 1 or 2 pulls with the choke. Today it took about 12 pulls (the choke is working fine, I checked). Once it was running the idle hangs high, at times during the ride it would bump against clutch engagment (4000 rpm). Given enough time it would settle down to 2500. We stopped for 1.5 hours at a restuarant and I could not start my sled when I came back out. Pulled about 40 times. Pulled two plugs and they were both bone dry. Poured some gas in the cylinders, put the plugs back, and started it that way. Idle problem existed all day long. Other then that the sled ran good. So good I think I might have been a little lean although it was a cold day and that usually makes her feel a little more responsive. Any thoughts?
Stopped on the trail when my sled turned 18 000 km. Not bad for a two stroke that still keeps up wiith most new sleds. Six kilometers later the speedo and odometer stopped working. Took the cable off when I got back and the cable appears to be fine. Wondering if its most likely the speedo or the take-off at the driveshaft?
Thanks for the Help.

Your idle hang could be your idle setting is too high given it settles to 2500 instead of 1800-2k. Recheck cable free play if you turn it down.
You know there is half and full choke settings? Tugging 40 times after a 1.5 hour soak and finding dry plugs would suggest you're using half choke or the choke plungers aren't supplying fuel.
Do both carb racks have the same jetting/adjustments?
If the speedo works by turning the cable where it's attached to the speedo drive gear, pull the drive gear and you'll likely find a wiped out drive shaft bearing. Be glad you found it before taking out the chain case.

Back your fuel screws out a 1/4 turn at a time till idle drops to spec after you blip the throttle. Worked like a charm on mine, and seemed to start easier, well it would idle by itself without having to half choke it to keep it running from a cold start.
For your idle hang:
