Compass Ignition for Yamaha XS 650
Yamaha XS 650 1970 - 1985Rated 5/5 based on 2 reviews.
Yamaha fans have asked us for it and now it's here! We are pleased to offer our latest ignition product - the Compass - a high-performance ignition to suit your Classic Yamaha XS 650.
The Compass system replaces your points ignition. It delivers precise timing, easy starting, improved throttle response and an accurate advance curve.
- Ease of installation
- Wiring plugs in to the original loom
- Eliminates the auto advance unit - found to be sticky and problematic
- Eliminates the points - maintenance free
- Huge increase in spark for easy starting a smooth running
Included with the Compass Ignition for Yamaha is a 12-Volt Dual Lead Coil with leads and caps. The dual lead coil outperforms the twin coil system original to the bike with double the spark voltage. It mounts similarly to the original coils and fits neatly in the same space.
The tiny control box, made by us in Adelaide, Australia, is easy to hide under the fuel tank and it's fully sealed against vibration and moisture. It uses a high-speed processor to generate the timing required for coil saturation and the advance curve without delays or jitter. It has some unique developments on the inside including high levels of voltage spike protection.
Events such as a battery becoming disconnected while the engine is running can lead to voltages spiking outside of the normal range and must be considered in case a fault does occur.
- Reverse polarity protected
- Spike protected to hundreds of volts
- Continuous overvoltage protected
- Pickup inputs protected
Reverse polarity is blocked out by a diode on the power input and the pickup inputs can tolerate full battery voltage should a connection go astray. It's designed to take anything the bike can throw at it but in case something extraordinary does happen.
The box is repairable thanks to an easily removable sealing compound.
The pickup unit that replaces the points plate (also made by us in Adelaide, South Australia) uses extreme temperature safe components and materials:
- 300-degree Celsius magnet rating,
- 200 C winding wire,
- machined aluminium frame and backing plate
- silicone lead wire
The generous component ratings ensure a happy life inside the hot engine environment. There are no active components inside the pickup unit and it's potted with a flexible sealant to cushion the internals during thermal cycling.
We call this system the Compass because the triggering rotor has two points like a compass! It's this unique shape of the Compass rotor and the accurate CNC machining process that gives the required timing stability and accuracy you would expect from electronic ignition.
Improved reliability, maintenance free and better performance in an easy to install package - the Compass System for your classic Yamaha ticks all the boxes!
An ignition system for people who love to ride their Yamaha XS 650!
Yamaha sounded completely different28 October 2021I recently had my son’s 1976 Yamaha XS650 installed with a Tri-Spark Compass ignition system made by Steve Kelly. It was still running a points setup and although it was running quite good it did have issues on cold starts. I dropped it off and it was fitted with his new ignition set up which included a new twin coil and leads. On returning to pick it up Steve started it and straight away I noticed the Yamaha sounded completely different. The exhaust note was more mellow with an even beat and the throttle response more precise. Some days later I went for a 60 kilometre ride in the Adelaide Hills with some mates, all riding bigger and newer bikes. I didn’t have to try hard to keep up. The performance was so different, it pulled hard and precise right thru the rev range. No backfiring or pops and misses just smooth running. It was such a joy to ride. I would highly recommend this system for all you XS650 owners. John (Dougie) Walker
