What for?
Off the top of my head mine is 420lb empty.
Can't really help you with stall speed - who knows how accurate the asi is in the stall, but mine is almost certainly more than 26mph. A figure I've seen is 38 kts which is in a very different ballpark, but I suspect closer to reality.
Mine has a 1600cc engine rather than 1200cc making it a bit heavier. Also, it's fairly easy to tell when you're approaching the stall.
