Hi guys i have a cbr1000f 88 model the engine is pretty fecked. I'm thinking about replacing it, was toying with the idea of putting a cb1300 in it??? Would this engine fit in or would i have to fabricate engine mounts? What other engines will fit, i don't really want to put another 1000f engine in it as there are too many issues with said engine. ie. cam chain tensioner drive chains and things. Any suggestion more than welcome. Thanks.
