Just picked up a 1980 xs 650 for a $100. Engine turns over but noticed the left exhaust valve (as sitting) is stuck open, other three are ok. Question is whats the best way to possibly free it up without taking engine apart. I do realize it would be better to disassemble and check everything out especially since there was no speedometer but thought lets see how it runs as is. Thanks in advance for any and all feedback. Thanks
