Honda-SOHC

Looks like your gonna need a bigger garage Tim. Nice find, especially when you didn't have to buy it.

That's a great looking bike you have there. When you say tidied up, looks as good as a full restore. Nice one.

Not really. I have a CB1300, my mates have CB1000R and Fireblades. The standard of the exhausts on these is superb. Don't know if Sankei are still the same company as back then, May have been sold out a few times. One things for sure, they are just trading on a name. And with products like that should be forced into bankruptcy. Can you tell yet that I am a bit pi***d off with these exhausts.

The latest exhausts have just arrived from AC-Motorradteile (Germany). As soon as I saw the box my heart sank. Its got the CMS logo with the CMS name roughly scraped off. I think you know where this is going. This is what they are listing   http://www.ebay.co.uk/itm/Honda-CB-350-Four-Auspuffanlage-Auspuff-4-4-Exhaust-Muffler-System-Sankei-New-/291477666989?   Just check the seam weld in the fourth picture.

Opened all four boxes within and guess what, same old crap just more expensive.

Is it me expecting too much from a set of exhausts at £880, or could they have bought a £30 angle grinder and done something with this garbage before its chromed. Needless to say this junk is going back as well, wasted £60 on postage now (nearer £100 now with exchange rate charges), this is past a joke.

There's a good set of 4 into 2 available for this bike, I think that's the way to go as everybody is selling the same thing. Have these suppliers not got any standards, they should be bleedin ashamed of themselves selling high priced scrap like this. And misrepresenting like that is just below slime.

And as for CMS being a top supplier, although they have been through the entire stock and could not find any good ones, they are still for sale without a mention of the crap welds. Same with DSS. Absolutely criminal behaviour. These should all be sent back to the manufacturer, and if it puts them out of business, then thank heavens for that.

Buyer beware of these unscrupulous b******s.

Thanks Bryan. Looks fine except for the grooves. Will reuse it then.

Can someone in the know have a quick look at these pictures and say if this tensioner blade is shot or re-usable. I think it's past it's best? Also, are the aftermarket tensioners any good or am I best with genuine. Thanks in advance.

Am going to try a conversion from the horrible PD carbs on the 750F2 to a set of K4 carbs I have spare. These are 20mm shorter than the PD's so am going to need to use the isolator rubbers off the K series to get the airbox back on.

Does anybody have a spare K head that can be measured. I need the diameter of the inlet spigots. Not sure if they are the same on the F2, I have a feeling the K's are smaller. The F2 spigots are 35mm. The K's carbs don't fit the F2 rubbers as the carb outlet  bosses are smaller. If the head spigots are smaller it could be end of game before I start so don't want to waste money buying parts that are not going to fit.

Have searched the internet and unbelievably cannot find anybody that has done this before. Have found a guy that has PD's on a K2 (Why) but not the other way around. He's also running pod filters that I don't want. So I guess its all in the spigot size, if they are the same I can just use K series isolator rubbers and it should all fit? Jetting is then anybody's guess.

Thanks Guys.

Thats a lot of words, here's the short version.
Does anybody know the size of the intake spigots on a K4 cylinder head.
Thanks.

Tim. Have included some pictures to help. The chrome shrouds are a press fit and are very tight. This is how I got them off.
Held the fork slider in the vice so I could see the little cutout area just below the shroud

Then after liberal application of PlusGas penetrating fluid, started it moving using a sharp screwdriver and a small hammer. Be very gentle with it so as not to cause damage. Once its moving, move around the shroud, keeping it even all around, gently tapping it out until its far enough out to pull off.

Just need to be gentle and tons of patience. Good luck!!
