X30 going to fixed pipe?


(Alex Christie ) #1

The talk in our tent last weekend at supernats was that the X30 will be going to a fixed pipe. Does anyone have more color on this (when)? What do people think? At first take I’m a fan (one less variable). I could see how some might miss adjusting the flex. Some of the front runners in JR were running lower gears with lots of flex.

I’m all for it. One less thing to break or worry about.

I too am for this. Makes a user friendly package even more user friendly.

Also, how about the guy caught for running a senior header on a junior :0

At SuperNats?! (20char)

Yup my understanding is they pleaded ignorance. Didn’t go well.

Yes, in the Junior LCQ. I knew a kid was DQ’d for an oversize header, but I thought it was a 26mm that had been (cough, ahem) “bluprinted” and went just over spec. Pretty sad if it was a full-on Senior header; at 320lbs with a Senior header he should have won by 10 seconds. I imagine the amount of cheating in the LCQ is pretty rampant. Plenty of guys take a shot when they are in the back and likely won’t reach tech. At Rotax Nationals this year I saw a kid who started in the back for the final passing 3 or 4 karts at a time on the straight at NJMP. It was hilarious; he could barely drive the thing anywhere else on the track. He was racing for a team that has been caught cheating a few times in high profile races.

As far as the fixed pipe goes, it is my understanding that it isn’t going to happen for 2019. I was told this by the same person who a month ago told me it was a done deal, so who really knows. It is getting late to make a fairly big change like that. They would have to have a lot of inventory on hand right now in order to facilitate the change.

I like the idea of it, it’s a much nicer pipe and a cleaner overall setup, but the lack of flex tuning will make differences between motors more obvious. You will have one less variable available to tune away a motor’s slight deficiency. The more “spec” a series gets means the better motors will just be even more better-er. In Europe, where they use the fixed pipe for Senior only at this point, you can still adjust the exhaust length via different sized gaskets behind the header. I was told that when we go to the fixed pipe here in the US, it will be one fixed size gasket only.
