Not trying to stir the pot........but...............I have to ask,
What list of category of quads to be ran, type of porting, is this an all drag or is this Dune port race, what size piston,  how can anyone tell before hand? Length of swing arms, paddle type, size, what fuel? C12?  do you both drain the tanks before hand? and use the same 5 Gal jug? No NOS systems , weigh in on each quad? ...........Would both parties be willing to do a teardown inspection afterwards?

Or just bring the best beast you have and run it?

Very cool, I hope this happens....by the sounds of it Kennerz was looking to race comparable bikes (one with a QV2 and one with an HPR#19) to put the “best pipe” argument to sleep, while Dale wants to have a “Zilla Wars” to determine the baddest bike period.  I’d love to see the outcome of both scenarios, so I don’t really care where or what they race lol.  Imo pavement would be the way to go if you want to take the swingarm/suspension/tires/rider ability/etc. variables out of the equation, but it’s hard to deny who has the faster bike when one makes it up the hill first (especially if there aren’t any whoops at the bottom).  Plus I think Tony ran NOS on the bike he raced Dale with before, so you wouldn’t want to restrict that.  Personally I like all the “drama” a good pipe comparison thread creates....it sure beats the same old questions over and over.
