IMO Don these stock HM300 and 341 pipes make these bikes and with out them they aren't quite the same. I have a 4-70 750KO that I bought in 2011 and it still has the original 300's, but are showing their age and I have had to do some minor patch work in places. Now since they are discontinued from Honda I wish I had bit the bullet and bought a new set when I could still get them. Well should of, could of, would of I guess. Now I'll just have to run the original ones until they completely rust out. I've had 3 HM341 pipes for several years and been trying to get the near extinct #2 pipe just like quite a few other members here are. Last week on ebay a near new #2 went for $685.00. I need one bad, but I not going to fork out almost $700 bucks for one f#%^ pipe.
To answer the question, No I don't think Honda will offer them again. I think their done Im sure the top dogs at Honda aren't to concerned about parts for a bike that's 40 years old. This bike set Honda and the Motorcycle world on fire in 1969 but in 2013 it doesn't pull a whole lot of weight.

Then why is one of the newest bikes Honda produced (the CB1100) almost like the CB750? 
I think Honda does care.

[Don R]

  I think Honda would rather sell new bikes than promote the use of 40 year old ones. Evidence, they ignored the SOHC world tour, rather than encouraging and participating.  My opinion is, they could sell bikes by promoting their heritage and long lived product.

Mr. Honda would be proud of us. It was his opinion, as long as we wanted parts they should be available. Corporate Honda, not so much.

Sorry for the ignorance, but what is a nono?

No numbers stamped in the pipes

[Don R]

Now the question is, what bike to sell to be able to buy the pipes?

Sell your 750 bike to get the pipes, and hopefully you have another 750 to put the pipes on???

[Mo]

Crazy! I've always wanted 4-4 pipes, but how much would these bad boys go for?

currently listed at $1652 but not yet in stock in Japan. with shipping, heat shields and hardware easily over 2K. Who knows if the price will rise or fall. for a while they were selling for $1180 on Ebay last year, I don't know who made those pipes Honda or Yamiya.

Mo...there were actually 3 sets of OEM 4-4 pipes for the early CB750K. You have the no number / no paragraph pipes on the very early ones in say 1969. Then you get to the HM300's which are stamped into the top of the pipe and were on the say 1970 - 1971. Then in 1972 Honda went with the HM341 which are a bit quieter than the HM300's. So the 1972 - 1976 had the HM341's. Honda was making them up until about 2 years ago. I bought my last set in 2011. As far as your question regarding price...the no number pipes are $1,652 from Yamiya in Japan plus shipping. The HM300 and 341's you see come up on eBay for high numbers. They used to sell for around $350 each from Honda, but one just went for around $600 on eBay. So to nail down a price that is pretty difficult. You just have to keep looking around and hopefully find a used set at a good price that you can clean up.

Probably a dumb question but could old pipes in good shape be replated?

[Johnie]

Not a dumb question...the issue is the carbon in the pipes contaminate the chemicals used in the plating process. If you are lucky enough to catch a plater who is about ready to dump his chemicals and replace them you are in luck. I have heard of some platers who will seal off the ends and opening in the pipes and plate. However, if you contaminate his tank he will not be happy. Plus, you have to have enough metal to work with...in other words the pipe can not be rotted.

I sold a K5 to buy stock style pipes for my Z1 [$1300]
but I have another K5 to take its place!

[Don R]

I'm hoping to sell the drag bike back to the PO's family after it's restored and running. That will provide funds to complete the sandcast.

[Don R]

Yamiya got in the order of nono's and sold out the same day. I snoozed, I losed. They say more early in the new year.

[Don R]

Did anyone here get any?

[Greggo]

Not me...half decent HM300's for mine.

A few things.
 A buddy got H1 mufflers replated. Nice job...so it is possible..
 Next Suzuki is making an effort to make some remake parts available, several model bikes are in the plans..... That in itself should or may wake up the other big 4 manufacturers.
 Pipes are a commodity, like maybe gold, when people need money, they may sell what they are sitting on...at a profit.
 There is companies like Yamiya. Dont forget that OEM relies heavily on vendors, so the pipes were probably vendor made... And there is a lot more money in it, to sell a small batch quickly, than to supply OEM original quantities.
 2k for pipes is not out of line for a bike worth 20K or more..it actually makes them cheaper to buy than 341 were to finish off a K4 or K5.

Thanks for the clarification guys! Just curious, but why did honda move away from the 4-4s in favor of a single exhaust? Was it simply weight and cost?

I recently bought a set of stock style 4-4's for my Z1, a Japanese company Doremi makes them, the quality ant fit are excellent. 
I see this happening to the 341's in a year or two.

[Don R]

A one day sell out should encourage them to make more. I've auctually been looking at whole bikes as a source of pipes. So far nothing that works price wise.

Back then it was mostly style,  we were taking 4 into 4s off at the shop and throwing them away because no one wanted them. That was around the Philly area of course...Larry
