I own a TA 200 that is about 3 1/2 years old . I recently went to my local honda dealership for an oil change . I have read on differant forums that there is a problem with the cam chain tensioner . I asked the manager,who speaks excellant English but is not a mechanic about replaceing the tensioner . He had no idea but called Honda . He then tells me it is a big deal and the engine has to be removed . Is this true ? Where is the tensioner located ? I have about 23000km and it was recomended to replace cam chain tensioner at 25000km....thanks ..Mike
