My son loves riding his dirt bike, but we have run into several problems with the different bikes that he has had over the years. It has taken quite a bit of trial and error to find the right parts to upgrade the stock bikes and avoid some of the costly problems that we have experienced in the past. Through all of those trials, we have learned exactly how to modify his new bikes and save a ton of money in motor repairs. To learn what we have done to his bike to keep it running long and strong, visit my website.
If you want to purchase a used motorcycle, you need to make sure that you inspect the motorcycle before you go through with the purchase. Just like when purchasing a used passenger vehicle, it is up to you to inspect the motorcycle and make sure it is up to your quality standards before you purchase it.
Check the Oil
Pull out the dipstick and check the quality of the oil. When you pull out the dipstick, the oil should have an amber color to it, and it should be transparent. If the oil is black and opaque or if you can visibly see dirt and debris on dip stick, that is a strong sign the oil has not been changed frequently enough. If the oil looks milky, that means water is getting into the engine, which can be really damaging.
Look beyond the dip stick and check out the oil filter as well to see if it is clean. Be sure to ask about how often the oil and oil filter were changed on the vehicle.
Check the Coolant & Radiator
Motorcycle engines tend to be really sturdy. When you check out the radiator, make sure that there are no bulges in the radiator hoses. Then, check the coolant. It should be either a green or orange color, and it shouldn't have particles in it, nor should look like the oil.
If you notice issues with the engine, you are probably going to want to pass on that motorcycle. Motorcycle engines are really sturdy, and it should be easy for you to find a used engine without any issues.
Check Out the Frame
Next, you are going to want to check out the frame. Make sure that the metal on the frame is not bent, paying especial attention to the metal around the shocks.
Always check the tires to make sure that low air pressure isn't the issue. Then make sure that the shocks are set up properly. If the tires and shocks are set-up right and the bike is still leaning, the frame is bent.
Finally, be sure to ask if any modifications have been made to the bike. Although modifications such as adding a body kit or magnesium alloy wheels can change the look of the bike and make it look more cool, it can also impact the ride.
If there are modifications to the bike, see if you can test ride the bike to make sure that you are comfortable with how the modifications change the ride of the bike. Although modifications and upgrades can look cool, you should make sure that they are safely installed and that they don't change the ride in ways that you were not expecting.
When purchasing a used motorcycle, be sure to look at how the engine was taken care of and make sure that the bike doesn't have body damage that will impact the ride of the vehicle. Make sure that the modifications made to the vehicle improve the ride and don't take away from your experience or the quality of your ride.
