The Competition Mod carburettor is the new addition to the Rooster Tail Engines modified carburettor series.
Bridging the gap between the Bearing Mod and the Full Mod carburettors, the new Competition Mod will perform exceptionally well, and fit right at home on the smaller engines.
As with all of our modified carburettors this one includes high quality, stainless steel sealed bearings on each side of the throttle shaft to help support and seal this area from dust ingress in the most demanding applications.
When this material enters the shaft bore area on a normal carburettor, it can cause excessive wear on both the shaft and the internal bore of the carburettor body.
This mod stops 99% of dust and sand from entering the carburettor bore and the engine, thus making it more reliable and saving you from an expensive engine rebuild from dust and sand ingress.
The Competition Mod carburettor also includes a lower pop-off pressure, with an increased closing pressure for faster response. Also the fuel flow is increased and the venturi signal strength has been raised for a boost to overall performance.
- Walbro WT-990
- 15.88mm bore

Very happy with modded product, with service to match. You will not be disappointed with the quality and workmanship that goes into making precision as well as excellence
With this carby fitted there is a obvious increase in response off the mark and the top end sings nice and smooth. I'm not to sure how to word it, but the engine does not seem, like it has more to give like with a standard 990. It is smooth and sounds complete.
