Previous owner washed out this bike but did not mention how bad he wrecked it . I need to replace the water joint but the top 8mm bolt is directly behind the frame and absolutely no room for it to screw out . Was told I can take off exhaust system, radiator , and LOOSEN the throttle body and twist engine to the left to get that one little screw out , I have the new part but wow I think I should have taken it to Honda to replace .
