| RIVA YAMAHA XLT1200 STAGE 2 KIT |
RIVA Flame Arrestor Kit is installed to increase airflow to motor. No internal carburetor modifications are performed. "Tamper Caps" are removed from high and low speed carburetor adjustment screws to optimize carb settings. |
| RIVA/Boyesen Reed Stuffers are installed into stock reed cages with stock reed petals. Stuffers increase fuel/air velocity through intake tract, resulting in increased throttle response and acceleration. "Tamper Caps" are removed from high and low speed carburetor adjustment screws to optimize carb settings. No internal carburetor modifications are performed. |
XLT Performance Cylinder Head is installed. Head features 41cc domes (including OEM gasket valume) that produce 145-150PSI compression (valves down). Girdled head design securely clamps cylinder down preventing potential cylinder cracking possible on modified motors. Requires use of 92+ octane pump fuel.
NOTE: RIVA also offers a modification service for your stock cylinder head. This consists of decking and redesigning the combustion chambers. This modification will produce performance similar to the RIVA Performance Head but does not provide protection from cylinder cracking. |
| RIVA Cat Removal D-Plate is installed in place of restrictive catalytic converter increasing top-end speed while reducing under-hood operating temperatures and allowing the use of regular 2-stroke oils. Our D-Plate is a high quality stainless steel replica of the plate that is standard equipment on export model Yamaha watercraft without emission controls. |
| RIVA Cat Temp Sensor Chip is installed to prevent warning lights & beepers from activating when catalytic converter is removed. |
| RIVA XLT Pump Seal Kit is installed. Location specific molded inserts are siliconed in to the voids of the OE pump inlet shoe significantly reducing cavitation. |
| RIVA XLT Performance Ride Plate and Top-Loader Intake Grate are installed. Our ride plate and intake grate combo increase top speed and significantly enhance handling characteristics. Prop spin and cavitation found with the stock grate is greatly reduced along with the modified XLT's tendency to drop on its nose when the throttle islet off at high speeds. |
Solas 12/18 Concord Impeller is installed without washer/spacer. Eliminating washer/space allows impeller to move closer to vein housing providing improved top soeed and reduced prop spin.
NOTE: Stage 2 modification is for competition use only. |
