The fifth step is to rebuild the engine. This requires special tools and special skills. If you don t know how to take the engine apart much more to rebuild it, you may want to leave it to the professionals to do this part for you. During the engine rebuild, there is a chance that you may need to find replacement parts for it. If you need to get your motorcycle s engine restored and you don t know anything about restoring motorcycle engines, it is a very good idea to get someone who knows how to do it for you. This may get you to spend some money for parts and for labor but once you get the engine working the rest of the restoration process will be a lot easier. If you see a motorcycle that is the same model as the one that you are restoring, you should grab this opportunity and make a bid. You can also find spare parts being sold in websites like this. Just make sure that the seller has a good reputation by taking a look at his or her rating in the auction website. This is one of the reasons why parts for classic or vintage bikes are very hard to find. This is especially true for bikes whose manufacturers are no longer in business. This is why a lot of vintage motorcycle owners are forced to scab together parts in order to restore their classic or vintage bikes. If you are restoring the bike to the way it looked when it came out the factory line, then you have to get it painted with the original paint scheme. Or, you can give it a new paintjob to make it personalized and unique. After this step, the last thing you need to do is assemble the bike. Do this part carefully in order to avoid any scratches and other types of damage that may happen when you put on each of the parts on the frame. This means that you will eventually have a fun time figuring out what design you should give your motorcycle and it will also help in making the entire restoration project a lot smoother. Whenever you are restoring a vintage bike, always remember that this is a fun hobby. It s not really a job that you should take very seriously.
