You should see my dad's sled! When he picked it up, it read about 160-165 PSI both cylinders.It was rated at 115hp at the time. When i rode with my buddy who had the AC ZR800 at the time I was always left in the dust lol. Not long after that I got a 900 ZR ! Was really awesome. Put 14,500mi on that one. Fun fun fun. Hang on kinda ride.
