:-[ >:(Well some of you may be aware I have started to restore my brown cb 750k4 and for some time I have looked at prices for the exhaust system from people like david s.s. etc.
Are they having a laugh? I cannot justify spending £1600 - £2000 on an exhaust.
I know , I know- it's not going to look or sound right but i want to ride this when it's done - but would I dare !!- and without the original type 4in4 I will be spending about 5.5 k including purchase price and possibly a MAC 4-2 exhaust. It will be years before I would get £7k for it. You may think I have overspent - or will do but I have been very selective on things I need to make a good job. I did buy an original seat for £400 and that's been the most expensive thing, then front mudguard,seat lock and chrome chain guard another £400. But as you all know you make a list as long as your arm when you take the thing apart and it all adds up. My only oversight was the back wheel which is the wrong one and will be another £320 including build and tyre.
Well anyhooo I'm enjoying the project and I'm really not complaining. I knew it would cost to do it properly right down to replacing nuts and bolts and electrics.
My point is :-
How come these are selling for about £5k restored
Is the mac 4-2 exhaust at £300 a good option for now then possibly if I want to sell in the future, invest in an expensive exhaust prior to advertising it?
-
You will always overspend but its always worth it ;)
I was lucky enough to get my pipes cheep enough so I will use the bike what ever the weather.
5k Sounds about right iv spent around 8.5k on two bikes and the bill is still growing. ::)
I don't think the price of the pipes push the value up much they just make it easier to shift.
I originally bought my bike as an investment but I can't see me selling it any time soon I like them so much I bought another. 8)

Agree with Mick,
It for me is a passion and makes me feel young as I had one in the days and I can not stop myself buying parts that catch my eye.
When I sell something that's no longer needed I spend it on another bit.3 to 4 years ago I think
I only paid 900 quid for the set and that was everything from the head to footrests from DS.
Now that for some reason no one can make them anymore when you can find them they are megga bucks.I have gone past the point of no return and no I will not get my money back but I love riding it and don't think I will never sell it.What the wife does with it when I'm gone that's up to her.
Cheers

Fair enough, you're right - and I'm not in it to sell and make a profit. It's just a hell of a lot of money.
I would love a set. I think the best bet is to hang on until the rebuild then see how i feel at the point when it needs some sort of exhaust.
-
sometimes if your lucky a half decent secondhand set turn up, I paid £120 I think for a set of hm341's from a guy in Ireland the lowers have been repaired but only on the underside so from the outside they look ok 8), cheers Mick.
-
Antony, you can bring the price of the rear wheel down by building it yourself. Stainless spokes £70
Wheel rim £100
Tyre £60
That will knock 90 off.
-
Antony, A set of exhausts up in your part of the country.

Trig,
Did see them the other day just one thing he claims they never had exhaust gas in them.
Why are the head bits a bit black?Apart from that look a nice set of 300s
Cheers
Bitsa

See what you mean Bitsa, Still buy them and then knock him for mis-description.
-
Thanks for the link - it's already up to a grand and I would say it will be one of those things that go not far less than buying new - and that;s without the heat shields.
No one has commented on the Mac 4 into 2 as a temporary. Are they any good???
-
Anthony
Sorry cant help you there the last non standard exhaust I had dealings with was a Moturd 4 to 1
in the 70s
Cheers
Bitsa
-
Just seen a set for a lot less but it says to fit 1977/78. Is there a big difference, can't see why they won't fit.
-
Not really sure but could be k7 k8 you can tell by the ends they are more rounder
Cheers
Bitsa
-
K7 K8 pipes do fit and don't look to bad.Better than a Moturd anyway.
You will need to fit studs in the engine but thats no biggie.
Mick
-
Mick,
Did not know that, obviously knew to change to studs.Do they look the part because I have seen some nos somewhere at a good price.
Cheers
Bitsa

I can't remember who told me.I think it was someone I bumped into when out and about I only saw a pic.
I think he modified the rear mounts but that can't be to complicated.
Mick
-
Wonder if its worth the risk. Could be an expensive booboo. Someone else advised me they could fit but the cylinder head mounts are different and I have to use the ones of a k8. mmmmmm :o
-
All you need to do is remove the Exhaust flanges and clamps and use the ones from the later modal that's all I did but in reverse on one of my bikes.

Trig
That set you found went for 1802 quid.Wonder how much I could get for my still boxed set of 341s?
Some still will pay big money.

Bitsa,
I rebuilt a engine last year for a 750k for a customer. The guy also bought a set of exhausts from Germany for £2,500 with all the fitting. I asked him how could he justify spending that kind of money. His reply was logical: "The whole set cost £2,500 and i am hoping they will last me at least 10 years, so that's £250 a year. Not bad if you work it out at £4.80 a week". At that point i thought i should up the price's for a engine re-build.
-
Trig
One way of thinking about it, but to get 10 years out of them they must never see rain,salt again and be removed each winter into a nice warm room me thinks.Back in the 70s cos only form of transport used in all wheathers cleaned regularly 2 years max.
Cheers
Bitsa

Bitsa, You have always said OEM parts were the bollox's. A motad would last longer than 2 years. The 750 in question has been family owned since new with 14,324 miles at last MOT. So it doesn't get out much.
-
Agreed Trig,
I had forgotten to take into account even moturd must have improved on their quality over the years also your right bike did not get out much, bit like mine now.Was winter more harsh back in the 70s? slid off mine a few times I recall.I mean last year did nothing but flood in the UK never remember winter like that during my youth.Same here no snow this year first time in 14 years.
In those days they did not cost that much as today a new bike was only 969 pounds on the road.
Cheers
Bitsa
-
Trig,
Forgot to mention yes I am a great believer in Honda/oem bits only because they fit straight away, I am not saying the quality is the bolloxs for all but for engine internals seals,o rings etc you know you can not beat them.You know as well as I do fit anything else and I dare you to tell me you have had never to modify something one way or another ie, DS pattern frackin seat.Tried one for 10 seconds removed and sold on ebay.
Cheers
Bitsa

Bitsa, Never bought anything patten/aftermarket from DSS. Engine parts, yes you are spot-on. Though i have used Vesrah gaskets without any problems. If the customer requires.
-
Again spot on Trig.
Versrah pads ok never tried gasket sets but did like another set cant remember what the name was but Bryan did Came in a yellow packet.If your customer is happy with what you say your the man.No intension of knocking you wish you all the luck in the world go for it.

I wonder if this is worth a try!!

cant make rusting worse so may be worth a try

The last Time I was in the UK a shop recommended Scottoiler to me.I have squirted this stuff down my pipes till it ran out of the holes.Done this for the last 3 years and touch wood no rust.
Did it also with my tank after wire wooling it no rust good stuff I don't know but so far works for me.
Cheers
Bitsa

Scottoiler. Diesel does the same job. Take a diesel car exhaust. It lasts 10 times longer than a petrol car.
A bit like the Vaseline Bitsa , old proven methods.
-
Trig,
You get me thinking would love to have a beer with you.Where in the world are you located? Git.
You sound as you are my double annoying,argumentative,opinionated and dying to talk with in a nice way.
Cheers
