A CB360 named Quorra (Vintage Racer)

[Lucius Fox]

Lets get right into it. I already posted my member intro so enough of that!

74' CB 360 nuf' said.

There are a few minor problems with the motor.... A couple leaky gaskets and possibly some funky valves. Running very well for the couple months I was using her as a commuter! Just needs a quick and fresh rebuild! I want to finish the bike as quick as I can, with high hopes of having her done in a month or 2! I tore into the bike yesterday and now she rests completely dismembered in the trunk of my car

QUORRA. Inspired by Tron; Inspired by the Ducati Sport 1000.

I know it doesn't have the same power.... but it doesn't mean it can't have the same look. I want the rear end to be a bit higher then the front. Real sleek lines. Do I just get a bigger shock to raise up the rear like that? Forgive my ignorance. I've never delved into that kinda work!

Attached is what I have done in the last day!

List of things to do thus far
- Sandblast The frame
- Clip ons/ Clubmans
- Powder coat Frame
- New Levers
- New Mirrors
- Seat
- Possibly a new tank (though I do like the 360 tank)
- Motor Work
- New Rubber
- Rear sets
- Suspension
- More to add once I think of it!

A little help from DTT is always nice! I will ask the questions when I got em'!

The frame is in good shape. And the wiring harness is mint. So I can cross those two off the list!!


ohhh... and she fits in my trunk ;P

Making a Honda look like a Ducati 1000...that's going to be interesting but I'm rooting for you!

Re: A CB360 named Quorra

Thanks bud! I know it's nearly impossible to make a bike that isn't a ducati, look like one. I just want it to have similar lines and features. We'll see how it goes anyways!

Re: A CB360 named Quorra

Sandblast and powdercoat your frame is the LAST thing you do after everything else but paint is done and the bike is all assembled. If you powdercoat first, then every time you have to weld a little mounting tab on the frame or grind on a spot you will be hating life. Also, if you start with the sandblasting and leave the powdercoat till later, your frame will start to rust.

I caution you about raising the rear with longer shocks. It will put the swingarm at an angle that may cause the chain tension to vary during suspension movement. Even more important, it will reduce the steering stem rake, therefore reducing trail. This bike already has minimal trail so reducing it further may make the bike less stable at speed than you would like.

I know what you're saying. I wasn't planning on powdercoating or doing any painting to the frame until all the excess was trimmed. It will probably be last. I was just jotting things down in a list. Not in chronological order....

As for the rear shock dilema. I really don't know how this will turn out. All ideas at the moment. The reason for posting here was to get input from you guys! Which is awesome and helps with making decisions like these. I will probably end up welding the hoop on with a bit of an angle to get the illusion! Or if you have any ideas of getting that look?

Re: A CB360 named Quorra

I agree, that you can get the stance you are looking for by elevating the tail without changing the bike geometry.

When you look at the rake of a bike like Ducati, and the rake of the Honda, you might think the Ducati has a pretty steep rake, why can't you do that on the Honda, too. One of the differences is in the triple tree offset. The Ducati tubes are further back, closer in line with the steering stem. That increases trail with a steep stem angle. Pretty typical on sport bike geometry. Do that with the Honda triple trees, and you may find yourself doing tank-slappers.

Glad to have a fellow Tron enthusiast on board! Once I'm done with her, She'll belong on the Grid.

Thanks for the insight Alphadog! I will definitely keep it in mind. Once I figure out the lines I'll really be able to decide what I want to do!

Re: A CB360 named Quorra (Frankensteining)?

Alright I need some help with this one! I'm sure someone out there can give me some insight. I've done a little research on swapping front ends. I would like to know why it is harder then it seems. I wanted to make my bike look meaner by swapping the front end. I saw "Ducatiboy's" 350 that had an 848 front end on it and it looked amazing. Total inspiration.

So I have bartered my way into a 2000 yamaha R1 front end/frame/swing arm/back rim. I haven't pulled the trigger on it but I would be trading with something really minimal that I hardly use and it seems like a hell of a deal. Even if I don't use it. I could sell it.

Bear with me. I am a complete novice in this category so any help would be awesome. I just want to know the viability of it working. There is an example of it being done attached. I might sound completely ignorant but without questioning, one cannot learn. Would it be possible for the 360's wheel to fit in that front end?

The one picture is what I am bartering for. The other is a cx500 with what looks to be a modified R1 front end!

Re: A CB360 named Quorra (Frankensteining) ?

I have done a fair amount of research on this, as Im planning a front end swap on my cafe project as well. What it comes down to is this: anything is possible.
There are generally a few ways of getting a front end swap done: 1) sometimes you get lucky (or do proper research) and all you need to do is buy a conversion bearing kit from allballs.
2) machine shims/spacers whatever you want to call them so that you can press your old stem into the new triple clamps. These need to be very tight, and many people also weld them into the new triples.
3) machine a new stem. It should fit into the new triples, but accept the old bearings so that it fits into your head tube.
Doing this machine work isnt too hard if you have access to a shop or your friends do and you know where to buy beer.
One thing that is worth while to pay attention to: the length of the new fok legs. They shouldnt be too much different from the length of the old ones. If theyre way too short you may get squirrely handling or bottom out. If theyre too long, you get lazy handling, but you can usually drop the triple clamps to correct this on modern USD forks.

This is just what Ive come up with from researching my fork swap over the past couple months. Often if you do enough research, you can find someone who has done a swap on your bike, and this can be a major resource for those of us who are new to projects of this scope. For example, I was able to find someone who had done a USD conversion on my bike, and laid out all the steps he took (albeit in german) but still.
Research is your friend

Hope that helps! And nice work so far

Fellow 360? Tron? I'm in...'nuff said

Re: A CB360 named Quorra (Frankensteining) ?

Glad to have you on board!

Update: I haven't figured out a way swap the front ends on.... I really want(ed) to, but I'm just not sure if it is going to work. Either way... I will undoubtedly make this bike look "Tron" before its back on two wheels


:As previously stated: If anyone has tips or advice for me, speak up!!

I haven't been able to do much with the bike. Still waiting to sandblast the frame. I have been working a lot so it's been on pause for the week! :[

Motor Is waiting to be torn into... which I am putting off : but I will get into that soon!


I'm going with a classic Black on chrome look. Seat is going to be a 2 up, all leather. Might try to make my original seat pan work. even though its a bit worn! Time will tell...

Thanks for tuning in :]

 

[edukaycheon]

Re: A CB360 named Quorra (Frankensteining) ?

What kind of seat are you thinking about?

Re: A CB360 named Quorra (Frankensteining) ?

Here is some progress for you guys that are watching!

I have the bike in a ton of pieces in so many different places at the moment... but it's all making its way back to me! I disassembled the front end and started to clean up the forks a bit. Waiting for new seals so I can get them in proper spec. Also cleaned up the rims! Still a lot of work to be done on them but i'm happy with how nice they are coming along. I plan on having them re-chromed at some point but I don't want to waste a good set of rubber. When that happens I'll be beefing up the tire size as well.... I just want to save a little money for now.

I have a small workspace, hardly and money and very little tools... So if you think you can't make something to be proud unless you have those things. Rethink it and dive in!

I plan on tearing down the motor this week. Are there any special tools I'll need? I've never done a bottom end rebuild so forgive my ignorance!

Here are some pictures of some things that I have done... and some random BS!

Nothing that you have posted so far gives any indication that you need a bottom end rebuild. Sounds like you just need to freshen up the top end, mostly because you have leaky gaskets. No reason to open up the bottom end unless there is something you haven't told us.

Re: A CB360 named Quorra (Frankensteining) ?

good to see a fellow barterer i hope you got that front end.... all the bikes i have besides 1 ducati have been bartered for

You don't say?! I am thinking about it more and more and I am not sure if I am going to open it up. There is a pretty decent leak coming from the bottom of the motor (I will post pics of it tomorrow) It only seems to be leaking whenever its warmed up though. For instance, I'll ride around town come home and notice a couple drops on the ground, then I'll check again in an hour and it wont be any worse. I'm not exactly sure where it is coming from... so I will clean up the mess on there now and try to figure out the source. I ordered a new gasket kit as well as a new set of rings. If you don't think I need to open up the bottom end... I'll listen :]

I did indeed end up with the front end.... not sure I will use it though! I'll just add it to the collection for a later day! I love to barter.... It's the best way of doing business!

Re: A CB360 named Quorra (Frankensteining) ?

Very common to have a leak around the shift shaft.
