80 custom

Postby Mello » Mon Feb 23, 2015 1:05 pm

I recently acquired 2 more CBX's. I posted the engine "issues" I had with the '82. Since that engine is now out of its frame awaiting some time and cash to pull it apart, I thought I would have a look at the other bike.

This has been modified a bit as can be seen by the pics. It appears to have been run a bit but the history of it is a bit sketchy at the moment. When I got it, the “bodywork” was not fitted so I stuck this on to see what it looks like. The 6 into 6 pipes are a bit rough but should clean up ok.

The fairing looks hideous IMHO. Think it will have to go.

I'm still undecided where to go with this bike. The frame lying next to it is a '79 I got amongst the bits. I was comtemplating trying to get it back to standard but there is a lot missing. I do have a spare tank, side covers and the correct '80 fender but no indicators, headlight, brake calipers, wheels, foot plates ....... The list goes on.

Apart from the seat mounting, it doesn't seem to have been too bad a job made of it. Not my first choice but with a bit of elbow grease, luck and some new bits she may make a nice bike, if not a "correct" CBX.

Getting the bike back to "standard" would mean rebuilding it almost completely. As it has been customized quite a bit, with a different front end, wheels and swingarm, I would work with this and just refine it to whatever your personal taste is.
I like the tank and the Ducati-style tail is a very popular modification.
I agree with you on the fairing. You can probably find a nice fairing with an integral headlight

Thanks for the input Mike. I have come to terms with the fact that it may be too far gone to return to standard, so cleaning her up to make a nice rideable custom may be the answer.

I agree, slap a headlight on it and go for a ride.
Save your money for unfortunate rebuild of your other engine.

What's the story on that tank?

It looks like a modified CB1300 tank.

To be honest, I'm not sure what the tanks is off. At first I thought maybe a CB1100R. Will need to look at a CB1100 to confirm. Here's some pics of it, maybe someone can id it?

It is a sweet looking tank. Fits the bike well too.

I decided to pull the carbs off, just to have a look at them. They were connected to the throttle cables, which need replacing and seemed to be adjusted more or less ok. Got them onto the bench - pretty dirty and corroded. I never ceases top amaze what people do or rather fail to do. Surely it is easier in the long run to just do stuff right? Take a look at these pics and I would be amazed if this bike actually ran.

Float bowls mixed up. Float bowl #3??? Missing screws! Idle screws!

No gaskets at all! Carb #5 has no float pin

On these pictures it looks very much like an 1100R tank, especially from the underside. 1100R tanks were aluminum (except for the knock-offs).
Check for the original front mounting brackets. They had to be cut off.

Looks like you have no correct #3 float bowl - none I see has a provision for the accelerator pump. Also, there are no second jets in these carbs because they are not VB 60 or 61. Look and see, but they would be VB 62-65. Yes, other than that they are still a mess!

Dave:

If they came off a 1980, they wouldn't be VB60 or 61, wouldn't they?
If they came off a SA bike, they would most likely be VB63s... :?:

The carbs are VB65. No idea if this was the original set or not. I have 2 sets of these, the other was on the 82. This set has screw in pilot jets whereas the ones in the pictures look like there are pressed in jets?

I have a set of VB61 as a "spare". Could these have been the correct carbs for the 80?

The VB65s are Prolink (81 and 82 or CBX-B and C) carbs for markets other than the U.S. and Canada (these were VB64)
To further differentiate, VB65A A were CBX-B and VB65A B were CBX-C carbs
VB61s were carbs for CBX-Z (79) for markets other than U.S.,Canada, South Africa and Australia.
So, the VB61 carbs you have were imported. 1980 (CBX-A) carbs were VB62 in the U.S. and Canada and VB63 everywhere else were the bike was sold (which is still the subject of different opinions)
