Tech Talk: How Exhausting!

The EPA and CARB continue to crack down on emissions tampering, and we are doing our part to comply with the letter and spirit of the laws governing motor vehicle emissions.

All the products that we sell that have potential emissions implications (carburetors, mufflers, jet kits, etc.) are labeled correspondingly on our website. Products that are labeled “race use only” can only be used in closed-course competition racing, and cannot be used on the street.

Tech Talk: Rims and Spokes

In this month’s tech talk, Carl talks about the importance of having matching rims and spokes when putting a wheel together.

We hear from a lot of customers who dent a rim, bend some spokes, or just want a different rim on their bike. We also hear from customers who bought a rim somewhere and just need us to get them a new set of spokes. Unfortunately, not all rims and spokes go together.

Tech Talk: Petcocks

In this month’s tech talk, Carl gives an overview of fuel petcocks and walks through the process of rebuilding one. Fuel petcocks sit between the tank and the carburetor, and are typically either vacuum-fed or gravity-fed.

Tech Talk: Seize the Day

In this month’s tech talk, Carl will demonstrate how to properly apply anti-seize paste. Anti-seize paste contains copper, aluminum, or zinc particles mixed with bearing grease, and helps keep your parts lubricated so that they do not seize up, even after being exposed to extreme temperatures or the elements.

Copper-based anti-seize are suited for high-temperature applications such as spark plugs, head bolts, or brake calipers. Aluminum-based pastes can be used for things like triple-clamp mounts or handlebar mounts.

Tech Talk: Stiff Spring

In this month’s tech talk, we will go over how to replace the throttle return spring on a Mikuni TM40 carburetor that’s often used as an aftermarket option on the Suzuki DR650, Honda XL650L, and Kawasaki KLR 650. Many of our customers feel that the stock spring is too stiff, making it harder to rev up their bikes and straining their wrists on long rides.

Tech Talk: Rings to Rule Them All

In this month’s tech talk, we are going to go over bonding the rings onto a Mikuni TM40 carburetor for use on the Suzuki DR650. We sell these rings in the DR650 conversion kit, and have received a few questions on the process of attaching them to the carb.

The kit we sell includes two rings: the larger for the airbox side and the smaller for the cylinder side. We use a good 2-part epoxy (such as Devcon Home 2-ton Epoxy) to bond the rings. Following these instructions will allow for many miles of smiles.
