Can you buy the spark plug for the Blast at any auto store such as autozone of oreilys or so you have to go to the hd dealer, or online?

Part# for NKG Spark Plug was: drp8ea-9 for any other newbies out there looking like I was. It's a medium heat .35 gap. Nickle alloy. (I've heard Iridium is like 1000000x better but I couldn't figure out the part number for that one.)

Sigh - you want drp9ea-9 - see my profile for the Iridium, right now the real hot ticket is the Brisk plugs.

Pulled my Brisk BR10ZS out of my XB after some days of sustained triple digit trips and they still look amazing.

NGK DCPR9-EIX are the iridium.

NGK heat range 8 are too hot and leave you very little room for error. If your boot tears, your piston melts, pretty much.

Brisk heat range 10 is equivalent to NGK's 9. A Brisk 8 is colder and a 12 is NGK's 8.

I'm running a BR8ZS in my super-modified XBlast and a BOR10LGS in my stocker. Both bikes responded well to the upgrade.

I plan on buying some more BOR10LGS and BOR8LGS so I can swap out the ZS plugs and see if there's any noticeable change.

FWIW: I used to run NGK's all the time, but in the last few years I've found they are not the plug they used to be. They work, but not the best anymore. I'm only using Denso's now (cheap or expensive) which clearly perform better. If the "Brisks" are recommended (by EZ and Jetlee), I'd use them. The other plugs I use are NLA!!!

Stock - 10R12A/10R12 - It works - enough said.

Our Favorite - Denso Racing Iridium IXU01-27 - http://www.globaldenso.com/en/products/aftermarket/plug/racing/features.html and http://www.sparkplugs.com/product.aspx?zpid=11283
This plug is known to fire even in the most extreme conditions, has a lifetime twice or more than stock, and is very difficult to foul. If you are unsure of your tune, then this plug lets you rest easy.

Semi-New Player - Brisk- which has the multi-spark - BR10ZS and the Torc-hammer design BOR10LGS - http://www.briskracing.com/brisk-premium-multi-spa rk-plugs/premium-multi-spark-racing-br10zs-spark-p lug-detail and http://www.briskracing.com/premium-lgs-racing-bor1 0lgs-spark-plug-detail
I and others running high comp (using BR08ZS) and stock running the BR10ZS find this plug to have an average plug life, however, the performance of the multi-spark plug is just like that of a multi-spark ignition offering a even more complete burn than the Denso, though it does not have the Denso long life - but at half the price of the Denso it is almost a wash. I tuned my bike for the denso and had to re-fiddle with the shimming for this plug. Many trying the BOR10LGS find it to work as well as the Torc-Hammers of old and like the build quality upgrade. Brisk is the maker of plugs for Lamborghini meaning a high quality material product. These plugs perform best when the tune is generally correct.

New Player - Pulstar With Plasma-Core - HE2RT8 -
https://pulstar.com/product/he2rt-8/?filtered=5391 4 and https://pulstar.com/
These are the new guys on the Block - offering the most bang and complete burn that can be had. Talking with Angelina - their phone tech - brought several things up of note - first this plug coolest operating number is actually a 9.5 equal to 9.5 NGK equivalent to a Denso 29 making it acceptable to a Buell engine running higher comp such as 11.0. No special wires needed, unlike other versions, and the 1125 would run JE2RT8. High quality materials used in build.

Prices:
Stock - 5 to 10 bucks
Denso Racing Irridium - 30 to 36 bucks
Brisk - 16 to 18 bucks
Pulstar - 16 to 18 bucks

I bring this up to inform, and allow questions. I did not bring up NGK or others because they are really no better than stock even in their Iridium versions, since all will drown equally under a rich tune - lol

The Brisk BR08ZS plug is too cold for winter weather - looks a bit shot as well - with only 1300 miles on it! Back in goes the Irridium Racing plug - which can handle the hi comp and cold.
