Recently bought a 1988 VT1100 and on the first ride noticed the lack of power, plus the mid range flat spot. The engine was getting very hot and when I stopped the idle was rough. Just had the carbs cleaned and set up, but the bike still feels like a piston is dropping out every now and then. The next thing I’m going to do is check the coils. Everyone tells me these engines are bullet proof, so I don’t want to go straight in with an engine rebuild. Anybody have any advice for me??
