Lets just say if you dont have one of these you need to get one. http://cgi.ebay.com.au/CABLE-LUBER-CRF250-CRF450-YZ250F-YZ450F-KX250F-KX450F-C-/380288722443?pt=Motors_Automotive_Tools&hash=item588af9660b If you have a clutch cable or any cable you need to lube then you need one of these. The reason i bring it up is because i did a search and noticed ALOT of threads about heavy clutch pull. I think this has to be one of the best and most needed tools any dirt bike rider could have and its helped me out on many a heavy clutch over the years. Whats your ''MUST HAVE TOOL''.
