Part: Honda CB450 / CL450 / CB500T Shockwave Electronic Ignition System
Why You Need This: For years we sought out a quality electronic ignition system for our beloved Honda CB450 DOHC twin-cylinder motorcycles. After testing several products on the market, the shortcomings of poor design quickly became clear. If we wanted an electronic ignition system for the Honda CB450 / CL450 Scrambler motorcycles we needed to design our own. 3 years of R&D and over 10,000 real road miles of testing later, we are proud to present to you the Common Motor Collective Shockwave Electronic Ignition System. The Shockwave replaces ignition points and condensers for the CB450, CL450 Scrambler or CB500T series of motorcycles. Never change or adjust points again. The Shockwave allows for accurate and stable ignition timing which means your bike will start easier, and run smoother (most note able at idle speeds).
Features:
NOTES:
1) *Warranty is only valid if bike is running a Common Motor #3023 combo regulator rectifier (besides you should be running one anyway as it is the single best electrical upgrade you can do to your bike!) If you have not upgraded yet, you can purchase one now with the Shockwave at a discount price. Early CB450's do not have a voltage regulator and later bikes that are equipped with one are very prone to failure. A voltage spike from a defective original (or non-existent) voltage regulator can potentially damage the electronic components of the Shockwave. Hence our requirement for a new unit to be in place to avoid such damage.
2) The Shockwave will work with stock ignition coils with a minimum resistance of 3.5 ohms. If you want to put a fresh set in with your Shockwave you can also purchase a set at a discount price as well. Note that our "regular" spark plug boot can work on the Honda CB450/500T but it will be snug. We suggest the angled spark plug boot for a better fit. A new set of spark plugs will round out the package.
CB500T Owners: Due to the coil bracket holes being slightly closer to the engine, the shockwave module bracket will make contact with the front engine valve cover. To mount the bracket, we recommend either drilling a new center hole on the module bracket and mounting it in the single hole or drilling and tapping a hole in the coil bracket for mounting the front bolt further back. You may also relocate the modules to any position on the motorcycle by extending the wires.
Installation Tip: Watch all the installation videos to make the process as easy as possible. You will need a set of feeler gauges to set sensor positions. A strobe-style automotive timing light is recommended to check the final ignition timing once the engine is running.
