CB500/550 / Re: 550f master cylinder
« on: April 21, 2024, 11:57:55 AM »
Not sure what you're looking for

On my race Honda 350 K4 I put an AP Lokheed adjustable one on, it matched the AP caliper. Got to the classic TT and everyone appeared to be using the David Silver (other suppliers are available ) replica ones, which cost less than the rebuild kit for my AP one!

I also have the DS  replica one on my Yamaha TZ race/road bike, it works well

Plus, I'll be fitting one on my Honda CB500 K2 RC181 replica

CB500/550 / Re: Clutch adjustment problem on CB500 K2
« on: April 10, 2024, 04:13:45 PM »
Thanks to everyone for their input

The adjuster clamp bolt had a filed down nut in place of the clamp (there was another nut underneath the ball bearing!)

I have used emery cloth to reduce the size of the adjuster - it fits!

Waiting for delivery of the adjuster clamp and a new ball bearing, plenty of grease and everything will be ok

I knew when I bought the bike that a bodger had been working on it, to give you an idea of his incompetence, below is a picture of one (of two) bolts that were replacing the long stud on the rear bottom engine mount (the nuts were filed down to fit in the channel the rod should pass through)

I'm one step closer to completing my RC181 replica - thanks to all on here (I'm sure they'll be more questions to come)

Thanks for the replies - much appreciated

I've now sourced the adjuster clamp

The model is an import from USA

Just need to sort the adaptor

CB500/550 / Clutch adjustment problem on CB500 K2
« on: April 09, 2024, 05:46:02 PM »
OK so an FB post couldn't throw any light on this issue (Julie seal was helpfull, thank you)

I took thr LH crankcase/sprocket cover off to replace the clutch cable - the clutch was working fine

Obviously a strip, clean & re-grease was required, but I noticed that the clutch adjustment clamp was missing and the clutch adjustor wouldn't move

I eventually removed the adjuster, with a fair bit of force, but it is obviously too big for the hole in the case - the hole is 26mm diameter and the adjuster is 27

Can anyone any light on this and suggest a fix

Also, does anyone have a spare adjuster clamp?

Thanks in advance for any assistance

CB500/550 / Re: Where to source jets for carbs for CB500 Four K2
« on: March 26, 2024, 11:13:33 AM »
Hi John

Thanks for the speedy reply, much appreciated

Standard are 100 & 40

From spending hours researching on this forum, I concluded that with pod filters and straight through exhaust that would be a good starting point for my build  (a bit richer than standard.....)

Happy to be corrected

CB500/550 / Where to source jets for carbs for CB500 Four K2
« on: March 26, 2024, 10:09:16 AM »
Hi all,

Looking for #110 main jets and #42 slow running for my Honda CB500 Four K2 (I reckon 4 of each will suffice!)

I'm based in South West Wales UK

Any suggestions as a good source - or anyone on here wanting to sell....?

Thanks in advance for any assistance

CB500/550 / Re: Replacement tyres
« on: January 27, 2024, 12:28:54 PM »
The amount of miles these classics seem to do these days I doubt the longevity of the tyres is a problem, they'll be cracking with age before they are worn out in most cases.

Aye,
I think that's probably relevant to most folk on this forum, but I still manage around 3000 miles a year and so offer my comments from experience.

Yes but what you failed to say is how long they last, 4000, 6000, 9000, 12000? I can get 12K out of a rear tyre on a 1300 and that's a bloody heavy lump and that's not toddling around either. Even my worst rear tyre a Dunlop lasted 6K, most of these classics won't do that in 5 years.

Personally I don't mind trading off wear for grip, I look at it as if it saves just one off it's paid for itself

Yes,
Sorry about that.
Got 3000 miles from a Roadrider rear and 5000 from a Bridgestone BT45.
Michelin Road Classics have done around 4500 miles so far and still looking good.

Once had 10,000 miles from a rear Michelin Pilot Road on my BMW R1150RT, but that was riding about like a very old grandad. Normally last maybe about 7000 miles.

Hope that helps.

Skoti

Not sure if this helps on this thread or not, but on my 2014 Royal Enfield Continental GT (only about 30 bhp) the Avon Road riders have done nearly 7,000 miles and still have plenty of life in them

I use Avon Roadrider Mk ll on all my classics

I find they're a good mix of grip, wear, ride quality, price and most importantly they don't do that horrible tramlining that affects most of the of the other tyres I've used in the past

They also do a softer compound race version..

CB500/550 / Re: New frame/engine bolts. What type?
« on: November 23, 2023, 09:15:43 AM »
Stainless stuff has not the same strength as normal zinc plated high tensile steel fasteners.
Not ideal for engine, shockers, forks or brakes etc.
But probably ok for other light duty cycle parts.

Anyhow for a show pony it probably won't matter.

Stay safe

Skoti

Yep, the scrutineers at the Isle of Man TT & Manx Grand Prix/Classic TT check (with a magnet) that engine mounting bolts are not stainless as they have been known to fracture

Doubt it would happen on a road machine though

CB500/550 / Cb500 Four K3 Jetting
« on: October 12, 2023, 10:55:47 AM »
Hi all,

Carb rebuild time on my CB500 K3 to RC181 Replica project (I'm in the UK, but it's a US model)

I'm planning on running uni foam filters and straight through 4 into 4 exhausts and looking for suggestions as to jet sizes

My normal guesstimate would be to up the Main Jets by 3 sizes (100 to 115), up the Pilot Jet by 1 size (40 to 45) and raise the needle by one notch (from middle to 4th down)

My thinking is that should make it on the safe side of rich and I can tweek it from there

I've searched the forum and have read that keeping as much of the original brassware as possible is a good idea, also that 'Nurse Julie' on this forum is a good source for O rings (other things as well)

Any suggestions as to where to purchase quality jets and gaskets (preferably in UK)?

Thanks in advance for any assistance

Pic is where I'm at with project at the moment....

So I'm not hijacking the forum, by posting a Yamaha, my K4 is behind it and the picture on the wall is inspiration for my CB500 Hailwood rep

Hi all,

Thanks for the add

I have just purchased a '72 CB500 four, which I intend customising into a Hailwood rep

Rationale being, as a pensioner, I will soon be too old to bump start my current Honda, so will retain the electric start on this one!

A million questions running through my head, but fitting the Hailwood style fairing over the sticking out alternator, without cutting a hole in it, will be my first challenge....

Current bikes are:

1972 Honda CB500 Four K
1972 Honda CB350 K4 (see avatar) that I restored from a wreck
1974 Yamaha TZ/RD250 (looks like a TZ A twin shock but has an RD aircooled engine)
2014 Royal Enfield Continental GT535 (for going to the cafe on)
2019 Suzuki GSX-R1000R ('cos every pensioner needs a 200bhp Superbike!)

TT & Manx Grand Prix fan, first attended in 1976
Other hobbies include: Paragliding, snowboarding, unicycling, skateboarding, chasing women and drinking beer
