Okay guys, I need spark plug help… I just recently purchased a very neglected ’01 rebuild and figured it’d be a safe bet to just replace some of the basics that probably haven’t been properly cared after. Even though she didn’t seem to be having any issues that aren’t unique to a Blast, I replaced my spark plug cable with a HDstock replacement, just for safe measure. However, the end that pops on the sparkplug just did not want to fit onto the spark plug. So our next conclusion was that the sparkplug was probably the wrong size as she was pretty much rebuilt with leftovers from god-knows-what. So I did some research, and found most people like the Iridiums IXUO-27 so I got an NGK spark plug, and went about seeing how to remove the tank to install it… Everyone on here and the service manual(don’t get me started on their vague directions) said removal of the tank was risky and unnecessary so I just unscrewed the old one out, and screwed the old one in. No problem, except she won’t turn over(only chugchugchug of the starter trying to catch). Took the sparkplug out, still cabled, and it’s sparking. Further investigation shows that I tightened the gapping closed. I figure I just need to buy a whole new spark plug and redo the whole installation process, but I’m not quite sure where I went wrong. My boyfriend’s convinced that the 27s are the wrong size and that I need to just stick with the stealership’s sparkplugs. Does anyone know what I messed up or can someone explain in laymens terms EXACTLY how to change a spark plug?? Should I be removing the fuel tank or is a 5/8 box wrench(what I used) good enough? Please help! I’ve got to take my bike to my ERC this weekend and I want to make sure she is in tip-top shape, nonetheless simply runs.
Thanks so much in advance. I know you guys are knowledge experts and I’ve already found so much info on these forums. I really appreciate it!

What exactly do you mean you tightened the "gapping closed"

The gap at the bottom of the plug, where the sparks created, the pieces were smashed together so my boyfriend used a flathead to pry them apart... then it sparked but still wouldn't start right when it was put back in... I have a limited knowledge of spark plugs, so sorry if this is flimsy/hard to understand.

2 things - did you smash the electrodes together, or did this happen after you screwed the plug into the head? If it happened after you screwed it in, most likely your piston is making contact with the spark plug (no good).
As far as it not starting, was the spark plug covered in gas when you took it out? If not, check to make sure you didn't accidentally shut off your fuel valve while you were reaching around under the tank. |

PS - use the factory recommended spark plug to make sure it is the right size.
Check the "thumper" section here for a lot of good Blast info

I think I smashed it while screwing it in? And that's what brought up the question if it's just the wrong size or what. Is it that hard to gap the stock plugs? I'm running by HD today to pick one up as a backup. No gas. I made extra certain the fuel valve was ON because my fuel valve is broken(I got her as a ripped apart rebuild) and its very hard to move the switch(it's been cut/smoothed down).
Thanks for the feedback though, Kilroy!
No one in the Thumper Forums have replied yet, even EZBlast :-/

Whoa - you should have asked in the thumper section - lol - first NGK sells an Iridium plug, however, that number goes with the Denso racing iridium plug - best plug you can get your hands on for a Buell - so far - lol - that plug fits, should have red locktite on solenoid base just above ceramic, 1/8" leave rest of solenoid bare, screw on solenoid top, then install, do not use locktite on the threads, you can use anti-sieze - lol - do not gap - they come from the factory ready to install, and trying to check gap on them would probably screw them up - maybe - that would be 40 bucks blown - shipped from the factory in individual padded hard plastic cases - also the proper number is IXU01-27. It directly bolts in.

If the NGK plug was iridium, you probably busted the wire trying to check gap - I would not waist my money on less than the Denso Racing Iridium plug because it is so superior to regular plugs, and its durability factor is far superior regular plugs in a twin, you can feel the difference.
