CB500/550 / Lovely weather, rotten fuel lines!
« on: May 30, 2020, 01:28:13 PM »
Got the bike out, checked the tyres, oil etc., turned the fuel on - petrol spraying out one of the fuel supply lines. Luckily I’ve still got a spare set of carbs ( long story) so swapped them over. No problem, had a nice run out in the sunshine.

Upon return, looked at the removed carbs, hoses cracked and split.

Can anybody recommend a reputable hose supplier that supplies hoses that withstand modern day fuels?

Also, just to confirm the hose size, I.D. 5.5 to 6mm? O.D. 10 - 11.5mm?

Thanks

Other Bikes / Yamaha XJ 900s Diversion 1998
« on: January 26, 2020, 11:08:32 AM »
Hi, my commuting bike is a 98 Yamaha 900s Diversion that is doing me proud in all weathers.

My problem is, that according to every specification I look at, the tank should hold 24 litres, giving a range of about 240 miles. I get about 10 miles to the litre so my consumption seems spot on, but I ran out of fuel after 135 miles the other day and it took about 14 litres to refill it.

I can’t say for certain how much fuel was left in the tank when it “ran out”, so it might’ve been that there was ten litres left in there.

There is no reserve setting on the fuel tap, only on or off. It is not a vacuum operated tap. There is an electric fuel pump.

The bike has a fuel gauge and low fuel warning light. As appears to be normal for this model, the fuel gauge is not reliable, so I use the odometer for my remaining range calculations. Apart from the light check at start up, I have never seen the low fuel light on.

When the weather improves, I am going to empty the tank and take the fuel tap off to see if there is an extended pipe or something inside that is reducing the amount of available fuel.

Another thing is that maybe the tank has had a huge dent in it that has been very well filled and repainted, but I doubt it’s this.

Anybody had any experience of this reduced range/fuel tank capacity on this model, or any other?

Other Bikes / Electric fuel pump
« on: October 06, 2019, 06:18:49 PM »
1998 Yamaha XJ900 Diversion fuel pump gave up the ghost. Upon inspection I found there’s a clip missing from the 5mm diameter solenoid spindle. The clip opens the points when the solenoid is energised and the spindle displaces.

Has anybody got any idea what this clip looks like?

I can find round wire clips, online, but only down to 6mm diameter shafts. An external circlip, that small, is not an option.

I’ve fitted a E clip for now, but this is loose fitting and I had to crimp the clip closed to stop it falling off. I’d prefer a more secure clip, but what?

Need some advice good people.
Took the carbs off today to check out the sooting up on 1, 2 and 4. 3 was ok.
Took bowls off, everything looked immaculate, put bowls back on.
Took diaphragm covers off and found 1,2 and 4 needles separated from their respective carriers. Retrieved very small spring and washers and reassembled them. Has to be said the o ring that holds them in place had seen better days. I will need to replace them at some point.
Anyway, confident that I’d found my fault, put it all back together and now engine won’t start, just cranks over and over, with the low fuel light on. (Only on when starter button pressed). Tank is full, fuel tap is on. There’s no fuel coming out of the fuel bowl drains.
I took the supply pipe to carbs off, no fuel coming through.
Took fuel pump off, connected to 12v supply, pump runs ok
Pump is not getting 12 v supply, why? What have I missed whilst refitting the carbs?

CB500/550 / What colour?
« on: June 26, 2018, 03:49:21 PM »
Lost my left side cover today so I’ve ordered a replacement, second hand one, from the States, that I will need to get painted.

I assumed my bike, a 1973, US, K2, was flake sunrise orange, but can I just check with you guys.

CB500/550 / Chain size?
« on: June 16, 2018, 10:07:53 AM »
My clutch cable snapped at the handlebar lever a few weeks ago.

When I had the sprocket cover off, first time on this bike whilst I’ve owned it, I found the clevis on the clutch operating arm, worn through on one side but the clutch cable was still attached and engaged. Once I’d prised the cable end out, the worn clevis wouldn’t work with the new cable, the nipple just pulled through. Bit the bullet and bought a new arm from D Silvers. Fitted this, new push rod and ball, courtesy of Trigger, cleaned everything up, greased everything and adjusted. All working good.

After about 200 Miles, thought I heard strange noise from sprocket cover and took it off. Found collision damage on the new clevis. Measured chain and found the pin lengths to be 21.5mm and width between plates to be 20mm. Checked split link and found pin lengths to be 23.5mm. I am guessing it’s the split link pins hitting the clevis so I’ve turned the split link so the clip runs on the inside of the chain for now.

I have no idea if this is the correct chain for the bike and an old thread on here says it’s not possible to fit o ring chains as they’re too wide. However CMSNL site sells an O ring chain that they claim is suitable for CB500K2 .

Can anybody advise where I can get the correct chain for my bike please? I’m not bothered about colour, o ring, etc., I just want the correct one that won’t rub on anything.

CB500/550 / Clutch Cable Routing on K2
« on: May 30, 2018, 02:29:44 PM »
Can anybody advise on the correct routing of the clutch cable on a K2 please?

I’ll b3 fitting a new cable tomorrow and just want to double check that mine is correctly routed. I presently have the clutch cable coming down the left hand side of petrol tank and the throttle cables on the right hand side. Is this correct for a K2?

CB500/550 / Clutch cable snapped
« on: May 27, 2018, 09:51:55 PM »
Clutch cable snapped at the handlebar lever the other day. I’ve ordered a new cable from Silvers and decided to take the old one off in readiness. Disappointed to find the clevis on the sled, clutch lifter damaged, even though the cable was still connected and clutch operating ok. Ordered a replacement one of those as well. Just waiting now.

In the meantime I thought I’d check out the clutch push rod with a view to fitting the new one I got from Trigger last year. It seems that my set up is a little different to that shown in the CMSNL exploded diagram. There’s a short section of rod/sleeve about 8mm diameter and about 60mm long that is made up of two pieces that rotate against each other and I can’t see the long push rod anywhere.

Are there different set ups out there?

CB500/550 / Plug caps
« on: May 02, 2018, 07:00:13 PM »
Bought a set of new plug caps the other day. They’re slightly different to the ones I have already in that #2 and #3 on my bike are straight. The new set has 2 x longer ones and 2 x 120 degree ones. Anybody know which ones go where.

I’ve fitted the longest ones to #1 and #4 and the 120 degree ones to #2 and #3, but not sure if this is correct as the HT lead routing to 2 and 3 seems strange.
