Shoodaben Engineering

"The way things 'Shoodaben' done from the factory!"

Welcome to Shoodaben Engineering - A website dedicated to the improvement and enjoyment of your 1986 to present Kawasaki Concours ZG1000 or 2008 -up ZG1400!

I'm Steve Sefsick, and my background in automotive and motorcycle engine building has always had a slant toward performance enhancement. My personal 2004 Concours, and now my 2012 Concours have been the development and test beds for the various products offered here

My Company is named "Shoodaben Engineering" which is code for "should have been". In other words, My Concours is what I think the Concours "Shoodaben".

 When seeking performance upgrades, I've found thinking "outside the box' to be a blessing and curse. While I can come up with some pretty good ideas to make more power, they are rarely easy to achieve. I have worked obsessively to tweak and improve my Concours, and along the way some products have been developed that will improve the performance, smoothness, and economy of your Concours.

These products are offered here, and are improvements the Concours owner with average mechanical skills can incorporate into his or her motorcycle. If you are interested in anything I've done for your Concours, drop me an email. I can do any of these improvements for you, all done on a custom basis. I also offer services from carb rebuilding all the way to full engine building on a custom basis. 


Each of my products is guaranteed to work as advertised, period. I'm very sure each item is well developed before I have released it, and always want you to feel comfortable in incorporating Shoodaben Engineering products into your Concours.
