Hi guys. I have been a member here for about a year when I bought my brand new Ninja 300 which I only bought as a test mule. I ran it for 700 Kms and ripped the engine out to make a major modification to showcase something I have been working on for over two decades, on and off. I picked the Ninja as it is so well developed already that if I could beat such a clever engine with my idea, it would highlight how good this thing I have worked on really is. Well, tomorrow I get the casting back for a brand new cylinder head for the Ninja 300 designed from scratch and cast in Brisbane Australia so I am on the last few months of machining and bolting together the most advanced cylinder head available and it is all designed to fit your favorite pocket rocket ninja. What is so radical, you may ask. Well, I ditched the camshafts and valves. I made a rotary valve cylinder head that has put almost 20 years of research on show. The only other modification is a Power Commandeer 5 (with fuel module) and new pistons. What I want to know from you guys is, before I take it to the industry, do I let the cat out of the bag and let you boys play with it too. Do I put a kit of parts together and make it available for you nutters to play with. Be warned though, it will be very powerful for a little 300cc lightweight, but exactly how much I will know late this year when I fire it up and test it. Want to know more, go to the website enginedevelopmentsaustralia.com and let me know what you think. All it is, is that after all this time of working on it, I am now looking at what to do with it after I have finished the trials. A petrol engine that pulls serious torque, can run 15:1 compression on pump gas and is lighter, smaller and with no valve bounce limits, less parasitic losses and more power due to more airflow, what could possibly go wrong.

Wow that is exciting news and I wish you best of luck with finishing your product. I think after testing and showcasing the final product and results, many would jump on this if you provided a kit with very details instructions to install.

I look forward to seeing your test results.

Omg YES make it available to us. I would much rather give you money and do mad scientist experiments with my little ninja than buy a 600 in a few months. Please please please dooooo it!

Not sure how you can run pump gas on a 15:1 compression. Wouldn't you need to get the octane to about 108? You can only advance the timing so much. It would be great for track/racing. I figure the die hard racers will mod their own engines...just saying...good look with your venture!

Am I the only one who noticed that "a member for a year" only has 2 posts?

This smells sh*tty. Plain and simple.

There are members on forums (including ours) that never post (or do it after years of being silent). Also OP had a link to a website that seems legit. Just two details that go for him.

OP, what's your patent number?

I'm calling bullshit until you show us.

For those thinking I'm an asshole for asking, either he doesn't have one yet and REALLY NEEDS ONE BEFORE HE SHOWS THIS, or it's snake oil.

Rotary pistons?

Rotary pistons?
No, you couldn't just put rotary pistons into a normal engine, it's a completely different design (most famously used in the Mazda rx-7). He's talking about rotary valves (which is what he typed, imagine that...). It's a different way of opening the valves to let air/fuel into the combustion chambers (and exhaust gases out) that doesn't utilize conventional camshafts like most engines do. Sounds pretty exciting abd I hope he shares more with us. Op, don't mind the haters, we are excited to hear whatever news you have and I'm looking forward to seeing you succeed in your endeavors.

This is not new. The Rotary engine was developed by Felix Wankel and made it's way to motorcycle engines in 1974 by Suzuki's RE5. The rotary engine was not fuel efficient due to uncombustible gas escaping which caused the exhaust pipe to get really hot. They recently perfected the gas leak. I'm not sure if they fixed the torque issues compared to their piston counterpart. In recent years they reintroduce this in racing...not sure how they stacked with the pistons. Unless the OP has made significant design changes, this design has already been patented.

Just like other members already pointed out, the OP is not reinventing the rotary engine- he is rather talking about a new engine head that contains rotary valves as opposed to your typical valves actuated by a crankshaft.

Not only is the OP clearly not talking about a rotary engine, but this point was clarified in the post immediately preceding yours. C'mon guys, read more carefully!

Ah, got it! You think the clutch can take the extra torque?
I'm sure this type of head could produce more power than the clutch could handle if you took it to its full potential, but I imagine the clutch could take a fair amount more torque than a stock 300 makes. I personally would love to be one of the guinea pigs lol.

OP: if you get to the point where you want to have people "beta" test the head in real-world conditions, PLEASE drop me a line. I would be happy to purchase a prototype head and install it myself followed by extensive dyno tuning/testing. It's great to see someone thinking outside the box and following through on their ideas! I would love to be a part of the process.
