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.

Unless otherwise stated, we will put the quality of the parts we sell up against any other companies' in the industry. Also, we stock the same parts from different manufacturers so that when back orders occur like they have been for the last year 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. If you want a certain brand part just ask (if part is back ordered this may cause a delay on your order).

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. It requires special tools and has to be done 100% correct. Many parts must be measured down to. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. It is the responsibility of the person assembling and tuning the parts to make sure they work correctly.

If it can not be fixed we will supply you with a new one. It must be sent to us for inspection, and Millennium Technologies will determine if the cylinder is repairable. 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.
