Goofit Single Pulse Generator (Ignition Sensor) Compatible with Honda CR80R/CR80RB/CR85R/CR85RB Motocross Motorcycles (1996–2002) Original Specifications for 2-Stroke Engines

【Ignition Sensor for Honda CR 2-Stroke】This ignition pulse generator (crankshaft position sensor) is specifically designed for the high-performance 2-stroke off-road motorcycles Honda CR80R, CR80RB, CR85R, and CR85RB (1996–2002). Manufactured to original Honda specifications, this product features a special high-temperature and shock-resistant housing that withstands the high vibrations and temperatures of high-revving 2-stroke engines. It precisely monitors crankshaft speed and position, delivering a stable and accurate ignition pulse signal to the CDI system. This crucial component determines the ignition timing, directly impacting engine performance, throttle response, and starting behavior. [Specifically adapted to the CR80/85 series upgrade cycles] This product is designed for the specific production years of the following models: Honda CR80R / CR80RB: applicable to models from 1996 to 2002. Honda CR85R / CR85RB: applicable to early models (generally from 2002 onwards, overlapping with later CR80 models). (Note: The CR80 series was replaced by the CR85 series around 2002. Since the engine design is similar, this product is compatible with both. Please check the exact model, VIN, and year of manufacture of your off-road vehicle before purchasing. We also recommend comparing this product with your own.) [Two-Stroke Ignition Troubleshooting] Replacing the original sensor, which may be damaged by severe vibration, have a damp ignition coil, or have aged due to thermal degradation, effectively resolves common two-stroke engine problems: starting difficulties or even starting failure (no ignition signal), extremely rough idling and risk of stalling, loss of power at high RPMs, jerky acceleration, and sluggish throttle response. [Precise Installation and Strict Air Gap Compliance] This product is a high-precision electromagnetic component. It mounts to the magneto or crankcase and engages with the flywheel release hub. The most important and challenging aspect of the installation lies in the precise adjustment of the air gap between the sensor head and the flywheel trigger mount. This air gap must be set exactly according to the specifications in the Honda CR Service Manual using a non-magnetic feeler gauge (typically 0.3 to 0.6 mm). Even slight deviations can significantly impair performance at high RPMs. [Scope of delivery] Single-pulse trigger unit × 1 piece
