Here are some questions and answers to help you along the way.

  • How long will it take to get my order?
    Many factors contribute to shipping. When a parts kit order is placed it usually takes 7 to 10 business days from time of order until the customer receives the order. Weekends and Holidays are not business days. But carriers do have delays due to weather and other events beyond our control.
  • Where is RebuiltPowerSports located?
    Rural Northern Minnesota. About 100 miles south of the Canadian border.
  • Do I have to pay Tax on my order?
    Only customers from Minnesota pay Tax. When you enter your zip code at time of checkout, the tax will be added if necessary.
  • Do you have parts for other kinds of vehicles?
    We have parts and do engine work for Honda, Yamaha, Suzuki, Kawasaki, and Polaris. ATV's , Side by Side's , and Dirt Bikes.
  • What kind of engine work do you do?
    We do CNC cylinder boring-honing, cylinder sleeving, cylinder plating, crankshaft rebuilding, cylinder head rebuilding, complete engine rebuilding, and full engine restorations.
  • What if some parts are no longer available or too old?
    We have partners that still have many Vintage NOS Parts for a lot of models back to about 1966. Not all OEM parts are still avaiable.
  • Do you offer Free Shipping?
    YES. We offer Free Shipping on all parts orders. We will also pay the return shipping for you on most repair services.
  • What is the turn around time to bore my cylinder?
    After we receive your cylinder, it will take about 2 weeks to get it back to you, unless more repair or special parts are needed. We can also supply you with a New Piston Kit & Gasket Kit.
  • How come I dont see my parts listed I need?
    With millions of parts available, it is very hard to list everything. We add new parts and engine repair services to models every day. If you dont see something you need, use our Contact Us page and send us a message. We answer emails 24/7. You will get a reply within 24 hours.
