anyone know of where to get the best price for front and rear pilot powers? wife keeps bitch'n at me to get new tires cause i patched the rear 5 months ago. not too worried about it, my brother-in-law patched his and rode it all the way till it had cord showing. but i dont want to chance it. dealer wanted around 400 but damn thats a lot. found it at competition accessories for 210 but not sure of shipping. dont know if i could find them cheaper than that. how hard to change them?
