Given the high cost of getting these from the UK and the fact that apparently the US source does not have the indexing tab for my bike (82/83 GPZ550) although apparently it will work, I thought about maybe trying some of the Chinese sources, it looks like they don't have the tab either because they are designed for different carbs from a different bike. But they are only 1/4 the cost, but the question is which one? They list by bike rather than size (the DF's) I suppose I could roll the dice and get ones for a Yamaha 650 Seca, which is what JBM says their H-68 is for, which is apparently what the K-68 is, or am I wrong, the K-68 from JBM is not the same as the H-68, it contains the tab.
Anybody know or for that matter tried Chinese diaphragms?

Is your computer a Lenovo?
It says those are made in Whitsett, North Carolina.

It's not cheap but at least you would know it would be correct as you saw in the post from Oct 2020 with tigerdrvr.

Not only did I participate in all those threads, I started one of them ;)

Considering NRP wants $176 and I bought a set of carbs (Keihin BTW, not TK for the 82/83) for $150 with good slides
I'd say NRP is NOT the best option.

I avoid buying Chinese whenever I can, but in this case it is less than 1/4 the cost of US and less than 1/10th the cost of British ...

So why not buy 2 sets, for half the money? Double your odds of success!

I used to be sceptical about Chinese goods mainly because of the crap you read online, my experiences are quite different. I have bought some excellent parts from China and haven't had a dud yet, One part I recently bought is a clone of another maker, the part is worth over $700 dollars to buy here in Australia, my Chinese part was just under $50 dollars with about $9 dollars shipping. both the expensive $700 part and my Chinese part are made from 6061 T6 billet Aluminum and all parts and seals are the same size, actually they look like they came out of the same factory and probably did.. You'll probably find most replacement diaphragms are now made somewhere in China....  Do your homework, there are some real bargains to be had, there is still some junk though. You'll find someone somewhere has bought those diaphragms and done a review....

One of the objections to Chinese made goods, is that they are often no respecter of patents. Those decent quality parts from there are doing financial damage to the company that spent untold time and money developing and designing that part. The more cheap clones there are in the market, the more the original developer has to charge just to break even.

I think that goes two ways TexasKZ, the prices for some of the parts are ridiculous especially here in Australia {not just here}, the mark up is unbelievably greedy, usually at least double the price they are overseas and even as bad as three times the price. When you have some understanding of how a lot of these parts are made its really hard to justify the price. Just because a company has the "patents" doesn't give it the right to rip us off, Manufacturing a lot of parts has become relatively cheap with programmable CNC machines and their like. I understand what you are saying but I don't think its that simple....

I avoid Chinese made stuff whenever possible.  Quality is always suspect.  You never know if the stuff was made with slave labour.  

My preference is to buy North American made stuff.  If not NA then Europe or Japan or Korea.  A few months ago I was searching for a borehole gauge.  There are all kinds of Chinese ones for around $100 but I went with Mitutoyo for considerably more money.  At least I know it was made to rigid specs.

And my computer was made in Taiwan, as was my cell phone.
I have a couple of Z1B's restored, an '80 KZ1000LTD restored, a 1981 KZ550 restored and a 2008 KLR 650 for off road fun. My wife has a 2019 Suzuki DR 650 for on and off road.

Anybody know or for that ma

 


I did buy some Chinese made carb rebuild kits (for a CBR600F3)..total  garbage, yeah they were cheap..for a reason.   NEVER again.. WASTE of money IMHO.  I ponied up the bucks and bought OEM and have had no issues since.  So basically I paid twice...and they didn't take the kits back when I complained. 
 
And I'm NOT political correct and never will be (and a proud American)...  And unfortunately we are all stuck with Chinese made goods..good or bad...that's reality.

My 2 cents sorry if it offends you, I can't help it...I'm an A***hole according to my wife ;)
