Hi all. Getting close to the end of the build now. Decided on a stainless Motad 4 into 1 as the NOS originals are nowhere to be had. Been looking for 9 months and only seen one in the USA at $2000 plus the usual import and postage (too rich for me). Anyway, started fitting the Motad and was surprised that their is no way to fix the header pipes to the collector box. Was expecting clamps or springs etc. Does this just go together dry or am I meant to use exhaust sealing paste? Doesn't make it clear in the instructions, just says as per diagram that isn't there. Its a shame ASh isn't on here anymore, he would know. COME BACK ASH!! Cheers all.

You should be using the copper crush gaskets and the stock collars, at least that's what I did with a motad on my 550.
-
Just push fit on Motad.
-
Cheers Trig. Push fit it is then. Was kinda hoping that would be the case as it will be on and off a bit as the mounting bracket is miles out. The main stand bump stop completely misses the bracket and ends up fouling the drive chain. Looks like I may be making a new bracket next week. Cheers.
-
Well what can I say!! Started fitting the Motad exhaust without the required instructions that were not in the box. Have posted some photos to try to convey just how awful the quality of this thing is. Clearly Motad have never fitted this to a real bike or they would know that it just does not fit. Good old British engineering.
The first issue is the fit of some of the pipes to the collector box. The picture demonstrates the I can push a matchstick down the joint. This is going to blow exhaust gases for fun.
Next we have the fitting collars that are too long. As you can see from the picture, pushed up tight there is no stud threads showing to get the nut on. The only option is to hacksaw 10mm or so off the end of the collar. But why the hell should I, this is supposed to be made to fit a CB750F2.
Last but not least, the bottom of the silencer mounting bracket is supposed to be a main stand stop. The picture shows that the stand does not even touch the bracket, it goes straight past it and fouls the drive chain. To repair this I will need to fabricate a whole new bracket. But again, why the hell should I.
I know Motad are following this forum, I hope they can come up with a few sensible suggestions as to why this does not fit without a fair degree of re-engineering by me. Just wondering, has anybody else had problems like this with Motad? Think I may just put it back in the box and send the whole pile of scrap back to them, then order a system from America that will probably fit straight off.
Happy days!!

I got a 4 2 1 stainless exhaust from Café racers in US (not stock or even like, but sounds great), very cheep and fitted perfectly. postage was cheep, and good help from them.

Definately speak to the Motad guy on the forum. Mine fitted perfectly with nice tight joints. Maybe your exhaust has been mis-labeled or something.
-
Something not right. Give Motad a call.
-
Have checked all the labeling and numbers on the packaging, and they all check out as correct. The bends on the header pipes appear to be correct, so maybe this is for a K or and F1 or something and as you say its been mislabeled. Have emailed Motad with the same pictures as on here, so will wait and see what happens. Feeling a little less irate about it now. Sorry to have unburdened on you all. Cheers all.

Where else would you get service like this?

well getting it right first time would be better
but as about the last uk volume producer- at least we are here to sort this out
you may need to be fluent in Cantonese to resolve most other supplier problems!
-
I understand from your email to our Sales dept - that much of your anger was because your dealer was not answering your questions
clearly first step is to resolve this issue (we are always ready when asked) and Dan in sales has already sent you an email answering your questions, sending another set of fitting instructions with diagram and awaiting your feedback so we can get this resolved and your system fitted
Ian
sent today as I am out of the office from tonight until Thursday and I do not want resolution delayed
-
Nice response Ian and hopefully this gets resolved amicably. I for one am really pleased you're getting involved here. Regards, james

its a simple equation- you guys pay my foodbill (along with 23 others)- and we are all quite keen on continuing eating
we just need to be told of any issues if we are to resolve them!

Nice to hear Ian....

Hi all. Just a quick update. Been talking to Motad via email and they have been brilliant. Unfortunately neither Motad nor myself are 100% sure what the problem is so we are looking for a workaround solution at the moment. So far they have made me a set of bespoke head rings that arrived today (shorter than standard), should be able to fit the pipes tomorrow. I should then be able to accurately measure for a modified silencer bracket. Never had after sales service as good as this from anywhere. Thanks Motad I really appreciate your help. Cheers.
-
Glad to hear this, I also found Motads after sales was great even buying a used system off ebay they were still able and willing to help with a discontinued rebel 125 system. Better than Honda after sales.
-
Forgive me if I have this wrong or misunderstanding not followed it closely but back in the 70s I fitted a motard exhaust cos Honda were too expensive frack me nothing like they are today if you can find them.Dont remember a problem at all except a crappy bracket to hold up the main stand.So please whats different? :D :D
Cheers

Hi Bitza. I guess the difference is that yours fitted the cylinder head, whereas mine doesn't. That's why they have provided shorter head rings at 23mm rather than the standard 28mm. Still got the bracket that the stand completely misses to sort out, but just going to the garage now to see if the header pipes will fit with the new head rings. Will report back later. Cheers.
-
Exhaust is finally correctly fitted. Motad (bless em) made me some new head rings 5mm shorter and now they fit a treat. On standard Honda studs the nuts tighten up with 2 threads showing through. Perfect. Not got a clue what was happening with the standard head rings. The header to silencer fit was due to "out of round" distortion from welding. I turned a mandrel on the lathe and tapped it in to get them round again, they now fit well. The rear silencer bracket was still miles out. I had to re-bend the bottom of it with a 45 degree bend to get it to meet the centre stand. Got it all perfect now. 10 out of 10 to Motad for after sales service. Shame they couldn't get it right first time. OH well!!

Are you now working for Motad R&D???

The question is what the hell has motad changed since the mid 70s?

Came a bit late to this but I too had a couple of issues when fitting a Motad 4 into 1 to my F1. I did feedback at the time but for completeness!!
Firstly I couldn't make the thing fit at all. Naturally assumed the problem was with the nut trying to fit the system! turned out 1 header pipe was the wrong one! Motad replaced quickly so no complaints there.
I would feedback though that the header rings were extremely difficult to push round the tight final bend on the header tubes and scratch up the finish. I used standard split collars and all was well. Maybe the shorter ones produced for this user would be better as standard?

Whoever is on NKK 38M but anyway, wouldn't be the first time I'd made that mistake ::)

Suppose if the light's bad enough it might not actually matter :P

all of our stuff is made here in the uk- by humans- and sometimes humans make mistakes
was difficult to track down what had happened to this system as the supplying dealer was unknown
but I can say that as the second model we ever made- we have made around 5,000 of these systems and if the correct fitting kit for the specific model is used it fits well
and in the very rare case of help being needed- we are ready to support
sales@motad.co.uk is the contact

Ian, do you make, or could you make a decent exhaust for the Honda 90 cub (85cc 12volt version) as most of the pattern exhausts on sale are crap! They rust badly within 6 months, and frequently snap the downpipe about 2 inches from the head. Stainless downpipe is available from Vietnam, but no sensible silencer to fit it!

sorry no- just not enough sensible people (like you) who realise the advantage of buying uk and spending a bit more- we cant get close for the people just looking at price
discussed with our production team to us all moving to £20 a week ( and all the bean sprouts they could eat)- but lets say it was a short discussion!
-
How many firm orders would you need to consider it though? And what kind of prices in chrome or stainless? There is a Honda Cub forum, and finding quality exhausts is like the holy grail, even gen Honda ones are now made in Brazil and not much better than far eastern stuff!

the condition 4 (severe external use chrome) is mega expensive and we will never downgrade so it would be stainless
I will do some "digging" to see how much interest there is- and I have no problem if you are on the cub forum I have no problem in you discussing it and posting up my email address ianmcdonald@motad.co.uk as a contact to see how many people might be interested
perhaps email me and we can discuss this of forum?
I took my bike test on a c90!
