A great question to consider with all of the fires out west this summer. The best way to get an answer would be to contact your local USFS or BLM Ranger station, or one near where you plan to explore. The local Rangers are going to be the ones that determine if you get ticketed while encountering them on a trail, so their attitude is the most relevant IMO. I have had good experiences with BLM folk, and none with USFS. The poor USFS budget is too small to staff enough patrol rangers around here!
With a stock exhaust I wouldnt worry about sparking a fire via the exhaust, but would take care not to park in tall grass that would contact the CC/muffler chamber under the engine. We have all seen low slung cars set green grass on fire via the YouTubes so its a real concern.
Spark arrestor or no, you DO NOT want to take a chance on starting a fire on federal land. If that happens, and you are identified as the ignitor, you get to supply the funds needs to contain the fire! A dunce-worthy young couple decided to fire tracer rounds at a closed shooting range earlier this summer near me, and they started a 12,500 acre fire that the state says cost $13M to contain..... not anything I want to be considered to be on the hook for, or charged with arson for as those kids are currently facing (Lake Christine Fire, CO)
For me, I decide based on current conditions, if its a tinder box out there ill for sure only take a spark-arrested bike off-road or even dirt county roads. Glad to see this discussion here, asking the question and being concerned in the first place is half the battle!
