Suzuki calls these "crank hole plugs" and this is an improved design from RCC TURBOS. The stock ones will strip because of the internal hex they use, these have a 19mm external hex, and come with the o ring. They will fit all Hayabusas and GSX-R 600, 750, and 1000. It also fits 2000-2004 DR-z 400 and AN650 2003-current . . . they are $38 each, and are available from me at POWERHOUSE MOTORCYCLES and also from Rob at BOOSTED PERFORMANCE. . .
