Overview
This is the original TPO Parts AIS (smog valve) Removal Kit for Yamaha bikes. This kit is used to remove the "Smog Valves" from your Yamaha's engine for race or high performance use.
TPO Parts' AIS system removal kit is the most effective means of removing the factory smog (AIS) hardware from your Yamaha. The TPO Kit requires no cutting, no drilling, no screws, and no tapping. It removes EVERY part of the AIS system, all the way back to the cylinder head.
This enables the COMPLETE removal of the AIS system including all the tubes and fittings which other kits leave behind. There are no screws to work loose or caps that can leak or fall off. TPO's self-locking plugs expand to seal off the AIS ports with no screws and no sealant needed. Tapping threads or drilling is NOT required, so there are no taps to buy and there is no chance of getting metal shavings into your engine. This is completely unlike any other design on the market.
The kit includes complete step-by-step directions and a set of billet aluminum plugs that allow for the complete removal of the AIS system. A set of vacuum caps is also included.
Installing this kit has the following benefits:
- Improved exhaust flow
- Weight savings, of about 3 lbs
- A cleaner, less cluttered, engine area
- A more stable A/F reading for more precise tuning on the Dyno
This is a must for race bikes! Get rid of some useless weight, improve tunability, and clean up your engine compartment all at the same time! This kit installs with simple hand tools. The kit includes complete step-by-step directions detailing installation.
