newbie needs some answers
 

Hello! I have obtained/inherited a 1979 or 1980 GS550L in pretty good cosmetic shape, but the engine is seized. We've tried to break it loose, without any luck. I am wondering if other engine sizes and/or other years' engines in a similar size would fit this bike. Of course, if anyone's got one of these bikes sittin' around the back of the barn...[8D] Thanks, Roger
