Worst company ever.I brought a jackshaft kit and to start off the holes to line it up on the motor was in the wrong spot and the sprockets were made of cheap tin. The product does not work and just break the chains and will not let you start the motor. Of course you have to try something to find out it doesn't work and that voids the warranty.when finally got a hold of customer after being on hold all day the previous day they said if you open the box to look at it, it voids the warranty they will not even give you credit like you would really want credit from these rude idiots in summary do not buy from these idoits the product and them are a piece of junk
