do a search on here, there is a thread on the manual. There used to be a guy in ponsonby who had a manual, I made a copy from his when I had one, that went with my bike out to manukau.
Tyre pressure - same as normal, usually 32/34, up to you
You need a new bracket and lever I would suggest going into a honda dealership or ask a wrecker - I couldn't figure out what model bike the bracket on there is from, its definately not from a cbx (the cbx one looked like your brake bracket)

The fun begins huh.
Lots of manuals out there on the interweb, can take a bit of finding though.
If I recall correctly the engine in the 250RS is the same as the XL250, so a manual for one of them might be helpful. I'll check if the one I've got at home covers the twin carb version, if it does I could probably send you a copy.
Otherwise they're pretty basic, and pretty easy to work on.

The bracket is stock, ive seen the same that I could buy from a shop in england showing the same part. The young guy at the bike shop admitted he ordered the wrong one.
Cheers for the tyre preasure.

Sweet, good info. would love a copy if you can find it. Cheers
The CBX was never sold into the US so it doesnt seem like anybody did manuals apart from the factory one.

- Whatever the cheapest 20/50w is, amount cast into the crankcase. Get a 4 litre
- Over 30
- The perch has been changed
- It's a CB, just weld some tube onto the rear subframe

Yeah hit that bitch with a MIG. Don't have to butcher it; just try to plan how you'd angle grind it off again later should that ever need to happen.
I had one... never rode it, gave it to a mate and he raped the crap out of it, so I know the sides of the tyres can be worn out before the centre :lol:

As for the rack buy a cheap one of trademe and make some brackets too suit...burn the man that said its just an cb:)
just get a after market perch with lever
Tyre pressure I use too run 32 front 36 rear have alook on your tyres it will have the recommended Psi printed on the sidewall

Had a look, my manual only goes up to '84, so doesn't cover the twin carb engine :( chch library has a copy of the honda workshop manual for the CBX250RS, but a bit hard to get to at the moment
My single carb 250 has a dipstick attached to the filler and the oil quantity is not cast into the engine, also has no oil filter just a screen so it pays to run some decent oil in the thing.
As for a pack rack, there should be enough mounting points on the back to hang one off (top of shocks, grab rails etc), all I did for my old yamaha was buy one off trademe and attack the mounts with the grinder and mig and make it fit. I now have a GSX1100 pack rack on an XJ550, not as pretty as it could be but works.
Levers are cheap, aftermarket around $20 complete, not so good on the trail bike as they break when you drop it but should be OK on a road bike.

Hmm, speedo reads on the odometer but not speed. Odd. And all the dsah bulbs are blown. And tach and fuel gauge dont work. Oh well gives me something to do.

Thanks, I have a few checks to do and if they dont work out I will go there.
Ive got power to the tach, will run a lead from the coil to see if the wiring is the fault. Want to check the earth on the loom but cant find it yet. Tank will come off over the weekend.
But so far Im real happy with the bike.

Speedo works when I put drill on the end of the speedo cable. Maybe it was not fitted properly or the driver is not working. But drive turns when I spin the front wheel. Will have to ride to find out.
Off to buy parts today.

There's usually a brass ring that holds the cable up at the speedo end, if it's slipped the cable may not be far enough into the speedo. Or could be the problem I had with my yamaha, the part on the drive that engages in the wheel was bent and wasn't driven by the wheel any more, or if it's been in bits the drive might not be assembled in the wheel correctly.

Any bike shop would be a good start....Hiflow filters are a good aftermarket brand

Little bit of work tonight. They got the correct lever in. the perches are stock. Just had faulty parts guy. Ive adjusted the gear and brake levers to the angle I like. And checked tyres. Back was at 20psi. Thats enough for tonight.

Went and got oil, filter, instrument bulbs, fuses and best of all gloves.
But real nubby question, should I have got motorcycle specific oil? And does 1.8 ltr sound about right?

Yes. Always use a 4T oil in your motorcycle.

Well first rides today. 2 and a total of 6ks. Bike goes great but after the first ride I had to adjust the clutch and bent the gear lever out so I could get onto it. Second ride was great. Much easier through the gears. Its going to be a few weeks before I have enough cash to go do my BHS as most of my money has gone on gear. Really would like to spend some time in a car park to just to get the hang of it.
The bike seems to be geared really high, cant practise the slow stuff for the test as the bike just wants to go.
Also need my speedo working. No idea how fast im going.
But really good fun, arms and back very tired. I was holding on to hard!!

Yeah I found it much more difficult doing bhs stuff (weaving between cones and the 10sec 10m) on the cbx than your standard gn250 - the cbx has heaps of low down torque so as soon as you get any throttle it just speeds ahead

Great days work on the bike today. Got the rev counter working, dirty contacts. Got rid of the overspeed wiring from the speedo which was causing it to fault. Then pulled the back wheel, fitted new tyre and adjusted the brake.
But dumb question, what petrol should it be running on? 91/95 etc

Now you're getting serious, I've never bothered fitting tyres myself, always figured the cost vs the effort made it someone else's job. Good work on the wiring stuff, don't know why people are so scared of it, it really is as easy as following it from one end to the other.
As for petrol, a single banger honda should be fine on 91, they ain't high tech enough to need the good stuff.

Cheers. I cant afford others to do it for me so if it needs doing....
As far as I could see the overspeed wiring just put a red light on when you got over 100kph. So wasnt needed.

So now the CBX is all road legal and running well, have I added value to it? What would it be worth now? So its an 86 CBX250rs with 13700ks on it. Great tyres etc.
Not going to sell as I :love: it.
But in 9 months, maybe something with more CCs will take my eye....
