Title: motad exhaust fitting
Post by: MikeM on May 19, 2014, 02:57:57 PM
fitting this motad until I find last part of my 4 into 4

Instructions on this don't match up with headers I have



instructions fit Q1M5H to port 1, there is no header pipe with that marking , all the pipes are marked M54-1S up to M54-4S

anyone came up against this before, thought it would be a simple job to fit these

tried fitting 1 and 3 first and then silencer but the last pipe is and inch out, no 2 cylinder the one you use the bolt to nip up the pipe with does not reach

Thanks

mike

just fit 1s-4s left to right. The end of the pipes should all be the same length. Fit the silencer last.

I have tried it 2 ways fitting 1-4 headers and then the silence........  also 1 and 3 as in their instructions then silencer and then pipes 2 and 4, pipe 2 seems to come up short ? by a good inch ?

when I had a motad I fitted all the downpipes first, then whacked the silencer on with a stout piece of wood.

thought about that... not sure how deep the pipes go in but when there all fitted at silencer end they are all different lengths

maybe that's what it needs mate a good whack to get the silencer on  :)

 ;D I know where bitsa is coming from but originals are not only expensive but hard to get, I have 3 out of the 4 originals

I know dave silvers are now doing 4 into 4 but there still repros and no reviews as of yet

so motad, yes not a great fit but whats the alternative ?

800 plus vat for  repro set or wait a few years to get originals ( if they turn up )

4 kids here and a mortage and hours cut to 24...... priorities have kicked in

I dunno guys, my Motad fits perfect, has nice chrome and looks fine. Only problem I had was they sent the wrong rear hanger which wasn't a big deal. I'm glad I saved £800 by fitting it.  :)

Hey Bitsa, grabbed a log from the wood pile, part number 0002-oak ( 0001 was not heavy enough) .   ;)

I put black tape on the pipes so I knew when they had gone in enough. (no part number)

After market exhausts are the best, who would want all that heavy chrome weighing down the bike and scratching on corners  ;D , I love my Laser system, and bike runs better.

One thing you will need is a stop to keep the centre stand from hitting the drive chain.

oh I wonder if mine will be the same, a long way from fitting it so will they honour it a few months later, mike is there any chance of measuring it so I can check mine?
Title: Re: motad exhaust fitting
Post by: MikeM on May 20, 2014, 08:45:16 PM

I was worried about this issue so put my head and barrels on temporarily so I could test fit my new motad. F*** it does not fit! Same as you Mike number 2 pipe seems to the problem, will have to get in touch with them.
Title: Re: motad exhaust fitting
Post by: MikeM on May 22, 2014, 07:56:24 AM
its a problem they are aware of mick, just have your invoice ready if you can, they will send you out a new set of headers

expecting mine today........  I was sure something not right..... number 2 header no matter what you do it will just not fit, its too short by at least a couple of inches
Title: Re: motad exhaust fitting

Just been on to Motad and they are sending me a replacement pipe, have to say no problem with them, very helpful.

I have never had any problems with motad other than of my own making - fitting dissimilar models and needing differet braketts. I must say I have found them very helpfull when I've needed spares to keep a discontinued exhaust systems running despite having bought most of their systems used (I think I've bought 1 new system for my gs125 and half a rebel 125 system) My motad Neta exhaust has been around 15 years now, got patched once in my ownership and was already quite old when bought - think it has done very well compared to how the original pipes were said to last back in the day, remember my motad neta was on an outdoor stored 550 and in daily use for about 10 of those years before being retired to spares shelf status. My chrome motad has fared less well and rotted 5 years after purchase off ebay but was again well used, I'll be putting a new end can on there. Don't knock patter exhusts - for almost every bike I've owned going OEM would have effectively written the bike off and I'd have gone over to cars years ago.
