Cheech

Hey Guys,
Cheech here from Red Rock Cycles in WV,USA.
Here a cheap,simple and easy little trick for those pain in the rear choke arms on the stock NT type carburetor that you have to reach down under your leg to flip on and off as you wobble down the road.

---

Step 1. I found a coaster brake arm strap layin' around the shop the kind with a whole in each end ...bent it in half to give it strength...

---

Step 2. Drill a hole out at the folded end with a 5/32"(3.97mm) bit,tapped it out  and threaded a knurl like on a set of cantilever brakes.Then I flattened out the 2 tabs on the choke arm and drilled a 9/64"(3.57mm) whole through the flattened tabs.

---

Step 3. I placed a spring with about the same strength as an NT carb throttle spring between the choke arm and our cable support.

---

Step 4. I used a throttle or brake cable threaded through a handlebar shifter arm (similar to the setup on a CNS carb) down through the knurl support, through the tension spring and through the flattened choke tabs

Step 5.  Position your choke arm on your handlebar in a full forward (choke off) position on the carb end pull your choke in a full down position (Choke Off,spring should be relaxed)  slip a brass cable stay up your cable and butt it against the bottom of the choke arm and tighten set screw.With a few fine adjustments you should have an excellent thumb choke. Be safe and as always...Ride the Breeze™
