Topic: New Motad Exhaust

[trueblue]

Damn Dave, you are really showing your age tonight, pacman, space invaders and KLG spark plugs .  I do see what you mean though.  I still have that chain out in the shed, I couldn't bring myself to throw it out.  Only because no one would believe me if they couldn't see it, hell some people don't believe it when they are holding it in their hands.  The stupidity of some people has no bounds.  JBMorse, my jetting is stock and air filter is a K&N in stock airbox.  From what I have read, Motad spent a lot of time and effort getting their systems as close to standard performance as possible.  I would definitely recommend one of these systems.

yeah i still cant fathom all the fuss over a simple exhaust that still has back pressure and fiddle with the jets myth,i still run stock jetting on a 4-1 thats a mix of transac megaphone ex retrorocket with home made baffle not loud,ive put plenty of fang miles on this set up.

[LesterPiglet]

I've never heard much about jetting and float heights until I joined this forum, seems everybody wants to tinker.

[Fritz]

Of course the color will come back.

I did buff off the golden oxidation once but it was a waste of time. The color will come back within a couple of miles.

I'm glad that a decent replacement for the stock 4-1 exhaust is available, although I really like the looks of the stock headers of the 550F so much more. I replaced them just because my stock muffler has rust holes at the tip.
It's a pitty that Motad does not produce a muffler that fits on the stock headers...

[Tree]

That Motad looks real nice.  What is your jetting and air filter system?  If you're not popping on decel you must be pretty close to optimum tuning, right?  I am curious how close it is to stock with this system.

  My 750k5 is all stock except for the Motad.  It's a  heavily baffled muffler.    I'll bet it's as restrictive as the original pipes.  I noticed that mine stopped  popping on deceleration as well after I installed it.  Seems to work great. (I like that orange / gold color the stainless takes on).

we used to- and took it out of the range around 25 years ago- the problem was that fewer people were runnign stock headers. If there is enough interest (and someone to loan a bike) we could reintroduce it

[motad_uk]

Mine has the stainless down pipes.  They turned golden within about 30 seconds of starting the bike, but I actually like the colour, it goes well with the red of my tank .  72500John thanks for the offer for the bump rubber, I went for a drive to the hardware shop and picked up a small black door stopper that should do the trick for a couple of dollars, if it doesn't I'll let you know.

we changed from chrome to stainless pipes around 6 years ago- so any more recent systems will be stainless. We are considering changing the silencer to stainless as well (no price rise)- what do you think?

[LesterPiglet]

I knew mine were chrome. 
The original headers were one of the main things that attracted my attention when I seen my first 550.

I reckon a stainless muffler would be brilliant, only I just bought mine.  So I would miss out on it .  Unless Motad would supply me an upgrade for free .  Again thanks for a great exhaust .

Glad you are pleased- and wont mention the Olympic cycling track pursuit!!!

I would be the first to buy one! Provided, the headers would not need to be modified.
But I see your problem. There are not many CB550Fs around that still have their orinigal exhaust. So I guess that most people who have a CB550F do not have the stock headers any more.
Though there are many good used stock headers to buy. It think it's hard to assess the market potentialhere...

[motad_uk]

the problem is that the stock exhausts were designed for a short life (Honda wanted you to buy a new bike!) which is why we have survived for 40 years

They generally fail fairly quickly - however as an example we have made for David Silver Spares a version of the 400-4 pipes with the trademark sweep of pipes- so it can be done but only if there is enough interest- these would be single skinned pipes (tooling up for double skinned would run in to 10s of £thousands

Would be nice to do- i had 200,000 miles out of a 500/4 and two 550s and have a soft spot for the bikes- i even almost forget that feeling of panic in the wet as the lag between no front braking and some kicked in!

Would love to see a muffler for the 750F that fits the stock header.  I think yours is better looking than the MAC which seems to be the only other alternative.

i put one on my 500, and i agree DDS has great shipping. you will enjoy it. quiet at idle but throaty enough at higher rpms. stainless down pipes area plus for the price.  if you need a bumper for the centerstand send me a pm. i have a few spares.

is that a skate wheel? that's smart.

I think a stainless silencer would be a great idea.

[super pasty white guy]

If you make a full stainless system for a 750F,  I'll be first in line to buy one.

[motad_uk]

we will upgrade the muffler to stainless probably in the next production batch- no change in price

dont want to start selling/promoting  on the forum- but its a change that is needed.

no plans for a muffler to fit standard headers- purely because there are so few bikes out there where the original headers have lasted

At least, with a stainless muffler, I had the chance to have it modified to fit the original headers.
Do you sell the mufflers without headers?

[motad_uk]

we do- in fact all systems are available as component parts

but the collector is integral with the muffler so would not go onto stock headers even with MAJOR modification

in 20 (or10 )years time your stock headers will be the only ones left in the world  and worth lots!!

put a full system on and keep these for your pension

[72500john]

a full stainless exhaust? dude do not make it so good you put yourself out of business!
one thing that could be improved on is the muffler mount with the built in angle for a center stand bumper. it needs to be a bit thicker metal. had to rivet two  .050 titanium doubler's to mine to stiffen it up to keep it from bending. otherwise great exhaust system, could not be happier!

Agreed. I welded in a brace, because someday I noticed the ugly noise of my centerstand hitting the chain because of  the bent muffler mount that came with the motad exhaust.

I gave the bike a wash and polish this afternoon, and I figured while it was clean I would take a video of the sound of the exhaust.  On the video it sounds to have a lot of clutch rattle, but when standing next to the bike it is barely audible, the crappy  phone mic seems to have amplified the noise.

[CB750F2]

Very nice Andrew. If you don't mind me asking how much did DSS charge you for freight? Thanks, Pat

[trueblue]

Pat, the total cost delivered to my door for the exhaust, manifold gaskets and a couple of valve guides for a head I'm doing up was just over $430 in our money.  I think shipping was 78GBP from memory.  All told it still cost me half what it was going to if I had bought an exhaust here in Aus.

[CB750F2]

Andrew, you have done well. I will re-check to see if they are available for the 750 f2. I didn't see one listed a few minutes ago. Pat
