I bought some new chrome grips for my busa (2008) and tryed to put the throttle grip on and it is stuck, i have tryed to lube it and get it back off but it will not budge. I am thinking about getting ones with the throttle tube built in (SUZUKI HAYABUSA GRIPS BILLET POLISHED ALL YEARS G01PC: eBay Motors (item 110578019199 end time Oct-24-10 08:08:01 PDT)) are these difficult to install and will this solve my issue by taking the stock throttle tube off. I am also guessing i have to open up the box that the throttle lines run into to install these new grips?
