TB Carb Kit, 20mm – TRX90

TBparts 20mm carb kit for Honda TRX90s. The perfect solution for replacing a worn-out OEM carb or unlocking better performance. The 20mm carb has a proven track record of performance, quality, and easy tuning over the 15 years we have been selling them for a variety of small Honda’s. This kit is made to reuse the stock air box and intake manifold. Works great with stock engines and even better with an exhaust/bore kit.

Included in the kit with the 20mm carb is an extended throttle cable to use with your stock thumb throttle. A carb to manifold spacer, so the carb can fit the stock air box tube. A dual feed petcock and set of 90° barb fittings to plumb the fuel line.

Key features:

• Proven 20mm Carb: Delivers improved throttle response and power over the OEM unit.
• Carb-to-manifold spacer (ensures proper alignment with stock air box tube)
• Extended throttle cable (compatible with stock thumb throttle)
• Dual-feed petcock
• 90° barb fittings for easy fuel line plumbing
