PRICES AND LISTINGS ARE SUBJECT TO CHANGE AT ANY TIME WITHOUT NOTICE. DO YOU MAKE A LIVING WORKING ON BIKES? ARE YOU A SHOP OR DEALER. PRICES ARE SUBJECT TO CHANGE AND LISTINGS MAY BE REVISED AT ANY TIME WITHOUT NOTICE. At BPRATV we sell parts from the best names in the industry, and we stock the same parts from different manufacturers so that when back orders occur we have an alternate part to send that is the same quality.
This would be the ONLY reason your order might be slightly different when it arrives. 99% of problems can be easily solved without returning the entire order. Once items have been modified, installed, or used in any way they are not eligible for return. This product is NOT DIY. Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person doing the work to ensure the parts work correctly. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. If it cannot be fixed we will supply you with a new one. Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most. Please work with us and we will ALWAYS work with you.
