Holtzman Atacc, is it worth it?

[cheddar brawt]

Just thinking about puting Holtzman atacc on my mountain max. wanted to see what you guys think? I usually have to travel to ride, so im always messing with jetting. Would want to be set up for 7000-12000' My sled is piped big bored and has a boostbottle, will that effect the atacc in any way?.....wouldnt think so, Anyway let me know what your think.

One of the guys I ride with has one on a polaris. It works well, his is piped and ported and he also runs a boost bottle and it works fine. He used to be f'ing with his jets all the time and doesn't have to any more.

Ran one on my MM with SLP pipes and all the other goodies.. Best investment I made.. Ride it at 1500ft change clutching and ride it in Cooke at 10k..

Right on! Thats what i wanted to hear, im tired of jetting and worrying about it! i think i will order it from slp, unless you guys know some where cheaper.
Thanks for the info.

Ya me and all my buddies used to run em on our mm's. Make sure you get your baseline jetting correct, and drop a size or two on your pilots. We had problems with them loading up at an idle. MAke sure you dont move the adjustment screw on the one piece of the compensator or it will bugger it up. All in all I think it is a good move, take some time to get it set up right and you will be happy. Oh ya make sure you mount the system outside the airbox, as the carbs on a mm dont vent in the airbox. good luck

Not sure what the price is from SLP but we always got ours Fett Bros Performance. Good guys to deal with also.

Boost is right on. Baseline jetting is must be correct!!

Good deal, I ran on my MM with slp pipes and a gutted air box. Leaned her out a little and ran perfect from 1500 feet to 10000. Do your plug checks properly and you'll be able to lean out as well.

Cheers

From my expeience(on my Polaris) I had to richen the pilot circuit because the ATACC was leaning it out too much. I had to richen it at base elevation and in the Bighorn Mountains. Other than that, jetting was spot on.
