Holtzman Engineering, Inc. manufacture a carburetor compensator, the Tempa Flow, which automatically adjusts for temperature with an easy manual altitude adjustment. Holtzman Engineering, inc. also manufactures Slide Springs in six rates for vacuum operated slides in CV (constant velocity) carburetors which are primarily used in the Yamaha RX-1 and Vector snowmobiles.
***Before ordering, if unsure which TEMPA FLOW will work best for you, please contact us and we can help you make the proper selection.***
***Returns subject to a 15% restocking charge. No returns after 90 days and without prior authorization. ***
New for 2019 is a Generation II TEMPA FLOW which has a slightly more aggressive calibration, more altitude range, and a thermal response time twice as fast as the original. This compensator automatically adjusts carb jetting for temperature changes and is set to work with -20F (-29C) carb jetting for snowmobiles. It can easily be adjusted, however, to work with jetting for any temperature. There is an external screw which easily provides manual altitude adjustment effective for up to an 8000 foot (2400 meter) elevation change. Along with the generic Tempa Flow Snowmobile kit, we have some model specific kits (see below). TEMPA FLOW works on Mikuni TM flatslide (except 01 and 02 Ski-Doo), VM roundslide, and TMX SnoPro carburetors. Also works on Keihin PWK and FCR. Call us for any other carburetor applications, including constant velocity (CV) carbs. One Tempa Flow will control multiple carburetors, only need one per engine.
CV Slide Springs
We have found some "easy" horsepower in these slide springs, specifically designed for three altitude ranges and inlets (stock or modified air box or carb filters) for the Yamaha RX-1 snowmobile. Improved throttle response and up to a 1000 RPM increase results from the use of these springs. A set of four springs come in a convenient carrying tube.
For Vector applications, use the Green springs for 0-4000 feet, Yellow for 4000-8000 feet, Red for 8000-12000 feet regardless of inlet (air box or filter application).
We also manufacture a Black spring which has a rate approximately 25% stiffer than the stock RX-1 spring which has been found to work well in some Turbo applications.
