Hurricane 600 motor install

[bbanna]

If I were to purchase a second CB-1 and wanted to put a F1 Hurricane 600 motor in it, it looks possible with one exception. A new upper motor mount bracket needs to be made. The rear lower and front lower motor mounts look to be in the same location.

I found a complete 600 motor for about $70.00. That is not all to bad and it looks to be a fairly good shape. Might be kind of fun to build a bike like that. Long term hobby project/ track bike.

I understand it is possible, but just curious about what it might take to put a 600 motor in the CB-1.

Talk to Kai Ju, I believe he has done that with his CB-1.5.

I have to look him up.

I am just wondering if it is worth buying the motor now and putting it aside for a future project.

Hey bbana,
     Long time no hear from.  How are things?  The CB-1 engine came from the Jap market 400 Aero.  The Aero was the little brother of the 600 Hurricane.  If the engine is in good shape and its only $70, I say go for it!!!  That would be a great project in my opinion!  Projects usually mean creating solutions to problem that may come up!  GO FOR IT!! How did you find a Hurricane motor???  You should play the lottery this week as well!

Hey Pete,

Things are going well. I am back in San Diego till the end of the year on a contract job with Qualcomm. Hoping this time to go permanent, but only time will tell.

I find all kinds of stuff when I least expect it.

I have been toying with the idea of another project bike. I start off with wanting to build something exotic like a CBR400RR or a VFR400RR or an RVF400R, but I keep coming back to the CB-1. I am just a huge fan of the -1. I have an MC28 single sided swing arm that would fit the frame just fine that came with a set of Honda MagTec race wheels. The project that I am currently working on is going to be my road worthy CB-1 the second project would be to see haw far I can go with building a CB-1 superbike for the track. I doubt I will get the 600 motor though. I like 400's and it is the 400 motor that helps to make the CB-1 so much fun. You have to work the bike to make it do what it does so well. Its the challenge of the bike that makes it so special as well as Honda engineering that allows you to swap parts from other Honda bikes to build your own special bike. Now with the internet making the world so much more accessible, I can source parts from just about anywhere.

What I will most likely do is buy another CB-1 to ride until I get my current project done. After I finish building my first pride and joy, I'll dismantle the second bike and start that project.

I just found the posts by Kai Ju. He used a 600F3 motor which I think and from the looks of it will take a bit more modifications to install. The motor I found is from the F1 600 Hurricane. If memory serves me correct , I recall a discussion about this motor. The CB-1 motor is derived from the F1 motor. If you look at the motor below the head, you will see it is pretty much an identical match. All the motor mounts below the head are the same. The size of the case is the same as well. obvious differences are the case covers. The only motor mount that needs modification is the head mount. The F1 hurricane motor has the mounting point centered where the CB-1 is forward. it would not be hard to design a new mount and have a couple of them machined.

From what I remember Kai Ju saying, (and I'm sure he wil be along to confirm), it was the rear mounts that he had to modify, but not by much. Don't forget to check the sprocket allingnment on the hurricane motor too, although I doubt that there's much difference.

The only mount that was a bolt on for the F3 engine was the lower rear, everything else was built from scratch.
From what I've seen the Hurricane engine will be really close.
You mentioned that you really enjoy the qualities of the 400 engine, I wouldn't worry too much about losing that sensation. The Hurricane engine is not as powerful as the F3 engine so you'l still get to row the gear box.
Pics please, providing you'll go for it.
I'm in Long Beach so if you want to peak at mine you're not to far away.

I'll try and answer any questions you might have.
