    I can't find the post where I said I'd reply once I tried it so here it is...
    after 500km of using the BOR12LGS in my 640 LC4, I have to say it works great. Most of the claims I've read are true. The most noticable differences from most to least are:
    - a little more oomph everywhere and rev's more freely (it was kinda flat over 6500, now it revs to 7500 very quickly)
    - less prone to stalling when plodding around trails in 1st gear near idle
    - fast starting. 1st kick from cold with the kick starter
    I'll be pulling the plug out for a check soon. I'm using a 157.5 now and the soot in the pipe is a little lighter in color and the exhaust is blueing further back then it was.
    If its doing a meltdown like I've read some sceptics say, (like sparking to the piston) its doing it very quietly.
    Its the Akropovic of spark plugs, except at $10-20 its a lot more power per $.

    Note: the body of the plug is slightly larger than the NGK, so it takes a good shove to get the cap on on. (more water tight now)

    I got such a load of crap when I started a thread about spark plugs... you woulda thunk I insulted somebody's dog!

    anyways I recollect someone or somebodies saying the Brisk are prone to failure... but your test sounds good.

    care to take a pic of the business end of that plug? :deal

    His test is completely anecdotal, just like "I use STP and get 45 more horsepower".....

    There, how's that for a load :huh

    Hi Meat :cry

    Thats not true, I waited til I did development and QA testing before I reported. I'll post a pic after I yank it out. Hopefully, without any molten blobs of aluminum attached.

    ahhh, its nice to see the peanut gallery is on the job!

    dag, your dog just needs a haircut and we'll be square.

    chrisC, didn't you see the dyno curve? jeebsus your askin alot for a sparkplug test... an anecdote is probably all a spark plug is worth.

    i would just like to see if its one of those open face old-skool race jobbies. you know cut the ground back until the electrode is fully exposed

    does that make the plug hotter? :evil

    yep, fully x-posed electrode - that's the old racer's trick I hear... where are all the old foggies when you need someone to recollect? :dunno

    english only? if you want to be democratic about it try Chinese or Farsi, maybe Spanish out of the romance languages...

    Oh fuck! Now I see it's an "extra turbo racing sparkplug"...

    I take back every negative thing I said. Where can I get one? :evil

    kinda like the emissions ratings in Cali

    LEV - low emissions vehicle :D
    ULEV - ultra-low emissions vehicle :evil
    SULEV - super-ultra-low emissions vehicle :bluduh
    PZEV - partial-zero emissions vehicle :huh
    ZEV - zero emissions vehicle :freaky

    when you have named something and then you come up with something better, its pretty damn easy to paint yourself into the corner of stupidity...

    still the plugs appear to improve performance, based upon the dyno results - UTI is no slouch.

    And I'm more prone to believe the independant observations of a fellow Advrider than some for-profit website.

    The website is a business and you are right there. But UTI is a hard-core no-nonesense mechanic's school (my friend's dad is the Pacific Rim Recruiter for them - his son went there too). So if they did the testing then it is probably legit.

    OTOH, the results may have adjusted between UTI and the webpage... who knows? gybeman may be the sole proprietor of Brisk Plugs USA... :lol3 :dunno

    but your right, he is a better source in this limited situation. of course those honda/toyota moders are so fanatical i wonder if they would skew results for profit.

    i would try a Brisk, if I knew which one. alot safer than trimming yer own neg ground. :nod

    Well, after 500kms of some gravel, lots of mud and 15/42 gearing. I'm sticking to this plug. Heres a pic of it fresh out of the bike. Excuse me if this does not work... first pic posting from a different site. http://ca.pg.photos.yahoo.com/ph/washburnsurfer/detail?.dir=/602a&.dnm=ea43.jpg&.src=phYou can see from the insulator its a nice tan color around each one of the four electrodes, so its sparking from 360degrees around the plug, and not grounding out to my piston...lol. Thats with a 157.5 main and 12 silencer discs I think. The biggest improvements I'd say is its pulls great, very hard to stall now at slow speeds and it revs quicker to 7500, where it was slower to rev over 6K before. The white residue that blew by the gasket wiped right off and it due to either not enough tightening and/or road salt I think. The gasket wasn't damaged. I read to use 20nm but I put it in by hand and it didn't take much to loosen it when i took it out, so its torqued now, and ready to rip.
    I'm a believer.
    Here it is before it went in.

    I emailed the tech contact at http://www.briskusa.com/ (Martin ??) and asked which was the right plug for the the bike. I can't find the original email, but I see they have updated the website now and it now has a BUY NOW button. It been almost 2 months since I got it and it was back ordered for 2 wks when i did order.
    It was $20US mailed to my door in Canada. I also found a NGK to BRISK convertor somewhere too, and it said the same plug #.
