Jetworks has been using ADA’s products since their inception in the early 1990’s. We found them to be the one of the few manufactures who produced consistent products that met and many times exceeded our expectations in quality and performance.
This Jetworks Head Kit is one the essential performance products for your Yamaha 701 SuperJet. The interchangeable domes allows you to adjusts and increase the compression ratio to your preference of fuel or elevation. Increased cooling capacity helps dissipate heat while the all O-Ring design eliminates blown head gasket issues and tightens the squish band, there by improving combustion characteristics, resulting in better response , a cleaner fuel burn, and above all, more power.
Another feature of this Jetworks Kit and possibly the most important benefit is the girdle system. The intake side of the Yamaha cylinders are know to crack when making more power but not using a girdle system, the girdle system itself is custom made and easier to use and install than any other on the market.
This kit is made of American aircraft grade 6061 billet aluminum that is anodized for corrosion protection and to add a little flavor to your ski’s engine compartment.
