Frequently Asked Questions

Do you sell TM Kart parts?

No, we only sell TM motorcycle parts at this time. If you require parts for your TM Kart engine, we recommend reaching out to TM Kart USA (website: www.tmracingusa.us; e-mail: barkstmracing@aol.com; phone: 310-714-6907), as they should be able to provide any parts you need.

Can I run pump gas in my TM motorcycle?

For best performance and longevity, TM recommends running fuel with a minimum 94-96 octane rating in your machine. Unfortunately, most Premium-grade pump gas has an octane rating of 89-93, depending on location. We have found the most cost-effective way to achieve the desired octane is to mix a higher octane fuel (such as race gas) with Premium pump gas.

What is the recommended fuel:oil mixture for TM two-strokes?

TM recommends 3%-3.5% (28:1-33:1), depending on model. We have found the traditional 32:1 premix ratio to be the best all-around mixture for most TM two-stroke models.
