I have a 1997 ZRT 800 i just bought recently. It starts ok and i took it out to ride for the first time. It was working well until about 20 mins later when it seemed that it was going to shut off. When i would try to accelerate, i had it full throttle and it wouldn't move past 5000 rpm. I had some 87 octane gasoline along with some Stabil in the tank from before. I am thinking that it is the gasoline. but i'm really not sure. and also if i attempt to start it again, it is a real pain in the butt. It almost seems like i have to wait for it to cool down. which is weird because i know it is liquid cooled. I even noticed a rubber burning kind of smell which was also weird. Any suggestions, would greatly be appreciated.
