Is your kid’s Yamaha TTR-90 running rough, hard to start, or bogging down? A carb rebuild can often work wonders, and this Labwork kit has all the essential parts you need to get that little engine purring again. This is a complete rebuild kit designed specifically for the Yamaha TTR-90 and TT-R90E models from the years 2000 through 2005. The kit includes the crucial small parts that wear out over time: jet needles, main jets, slow (pilot) jets, the float valve, and the float chamber gasket. Everything is new and made to a good quality standard. A clean, properly rebuilt carburetor will restore smooth throttle response, reliable starting, and overall better performance. This is a great project for a handy parent or small engine enthusiast. Just remember, the picture shows exactly what’s in the kit, so you know what you’re getting. Bring that trusty dirt bike back to life!
