No. And this was discussed in another thread on the very first page of the forum, just a couple of days ago!
You want R5300A's.
Actually, more accurately, it is possible to use the R7282 (with the corresponding cap), but you need to be sure you get the correct version. The R7282 usually comes without a gasket.
The "correct" plug for the NSR250, as specified by HRC, is the R5300A. _________________ Andy.

I think he probably means, rear head on the front, and unless he specificaly wants yo use shorty plugs, ie, performance etc, he does'nt have to. You can run standard plugs without clearance probs with the head conversion,well i did for a couple of years. _________________ Proud Father of , 05 ktm 400exc supermoto 2018 honda crf rx supermoto
Les, that's not entirely correct. If you run anything other than bog-stock settings, then you run the risk of hitting the plug cap. It's even possible if your front forks are a little saggy! If you run HRC settings, or HRC forks, then the short pugs are a must. Some people are also convinced that over-sized tyres are essential, and that will cause problems too.
Yes, you can orientate the head differently, but then you have to consider both the plumbing and coolant flow differences. Just because something worked for you, doesn't mean it's right for everyone... I've seen a lot, and I mean a lot of broken front plug caps over the years!
The racing plugs do gice a far superior spark, even better when combined with HRC coils, although it won't be anything you can physically feel. As with many things, it's all the little bits that add up. _________________ Andy.

Yes I follow you , must have been a typo . Buy your parts from Andy , at least you know they will be correct for your bike .
The UK NGK parts list doesn't show the R7282 with the correct crush gasket as available. The only part I can guarantee will work is the R5300 and its' corresponding cap. The R5300 is also about US$40 cheaper! _________________ Andy.

Iam now running shorty plugs, but i certainly never had any fouling issues with standard plugs, with the head conversion and with the yokes dropped down, buy like you said Andy what works for one dont allways mean its gonna work for others, Perhaps cause i'm an old fart i dont brake hard enough, jonnymac keep telling me i'm too old for all this speed malachy. _________________ Proud Father of , 05 ktm 400exc supermoto 2018 honda crf rx supermoto
The 7282 does not need a washer as it is not the detonation counter type plug . The 7282 A is the detonation counter type plug . But both of these plugs are wasted on a nsr as said before .
Hi Guys....thanks for the info....the plug choice issue is a bit confusing. It would have been easier of the market place OR Tyga had the plugs in stock but neither do. I searched the interweb and found what I though was the correct plug. The complete plug number is R7282-9 # 4753. There was no "a" after the number and from what I read...the heat range of 9 is correct to. I'm use to buying plugs for my VJ23 which is much easier! I'm buying the cylinder head with the central spark plug location, the correct plug (hopefully), the hrc coolant hose and new cap for the plug. Also going to buy a top end rebuild kit and have the card reflashed to the HRC spec.
I'll most likely have a look at the barrels and send to whomever does the port work listed on this website:-) _________________ "If your not first, your last!" Ricky Bobby
I can get the R5300's, and the caps, but they are on pre-order. I just ordered up 4 and they were about £150!
I will change the wording of the advert to reflect the fact you can pre-order them. They should be with me in about a week, once ordered. _________________ Andy.

Btw..the plug was $40 US shipped. If Its the wrong plug, I'll sell it on eBay and order from Andy:-) _________________ "If your not first, your last!" Ricky Bobby
