I agree with Jess. Do the math. Sparkplug adapter $100 plus average plug $10, that a cost equal to four of Sam’s plugs for $35 each and you just broke even not to mention you had to pay up front to make your money back. It’s a no BRAINER! Pay more and wait for a plug that seems to work or spend as you go and have the properly engineered plug? At the same time you support someone who will answer questions and have parts you need for your bike.

Just recieved a plug adapter from fleabay came with a used DR9EA. I have to say the bike now smoothly idles at around 1200rpm instead of the slightly eratic 13-1400rpm also rides as good if not better than before. Any suggestions on plug that came with it or should I just use the CR9E.

Could be that you just needed another plug and this one did the trick for you. Just my thoughts.

I'm not sure how much Jess charges for them at Rotary Recycle if he has them but I'm thinking they may be less. He might have even mentioned about his plug supply in this thread or another one on the board. I'm sure Jess will chime in when he reads this. Myself, I prefer to have the original type plugs in any motor that I have, the RE5 included.

40 GBP for a lousy spark plug seems steep at first glance. ...or maybe not First problem is... THERE ARE NONESecond thing, they were 26 bucks US from Suzuki in 1975... I get $45 each for them now, you do the math. My supply is VERY limited, when they are gone, they are gone... Eventually, I will have no factory plugs left to sell. As they supply dwindles they will go up in price. It's simple economics. I had a call from NGK UK asking me if I had plugs. I said, "You guys made them... how about making some?" They said, "sure... 10,000 minimum order" Even if cost were 9 dollars per plug... Are YOU going to pony up 90 grand? ...Well? It is my belief that plug adaptors are an eventuality... period. Cutting up an old plug and stuffing in another is not an option. Some guys have had good luck and I am happy for them. I have, however, seen several engine proper units utterly destroyed using the fleabay plug adaptor... That said, I have spent the last year working on a good design that eliminates the inherent problems in every adaptor I have seen. I have come up with what i believe is a workable, tested design. Now the issue is the cost to manufacture. I am not an engineer/cad guy/machinist, so there were many many attempts to get it right. I then had to test the design in actual use for about 1000 miles. Once I was satisfied, I had to pay a guy to draw/create a cad file to get the things made to my specs. Now I have to make the decision to throw another large pile of money at them to try and get a reasonable number made, in hopes that they sell and I have not just chucked several thousand more bucks into the fire. Lastly... if I get them made and they do sell I get to hear, "$XXX.00 for a plug adaptor... what a rip off" So let me think about it.... Hmmmm... Nope.... 40 GBP for a spark plug that has not been made since 1985 is cheap. Just my 2 cents... I'm all for other opinions Best, Jess

There are two types of adapters that are, or were recently, for sale on ebay. One is drilled for the same plug size you would use if you drilled out an old stock plug and a common plug for that size is: NGK CR9E. The second adapter is drilled for the plug used in the Mazda RX8 which is: NGK BUR9EQP. I believe the RX8 plug is unique to that car. Where do you find the adaptor to run a BUR9EQ plug? It would be nice to stick w/ a proven rotary specific plug.

Wow, they pop up here and there every now and then but at $70 US I think not. I would rather just buy an adapter! I don't have a disposable income for spark plugs.

What was the NGK AU10EFP originally designed for and is it still made?

10's are just another plug for the RE5...
The are one step colder and Suzuki suggested replacing the 9's with a ten for road use.
Their position was that 10's would foul less. In practice, I have found little difference.
It is not a new plug... they have been around a long time. production ceased on them over 20 years ago.
Someone in England found a box or two on the shelf... They pop up from time to time.
We sell them for 45.00 each. We have no 9's available for sale anymore.
Best,
