I have a 2006 Yamaha attak with a big boy spring from pioneer and I have been fighting the set up from day one. This year Im going to use the bergstrome triple point. my weight is around 225-230 dressed to ride. Any set up help would be great.

first, you will like the bergstroms. his shop is 5 miles from my house. id advise keeping your old carbides for the marginal snow days in early and late season and swap the bergstroms on for when the snow is good. the bergstroms are tough, but why trash them in bad conditions. as for your attak, check the weight transfer setting. mine came from the factory full forward. i just noticed it last month. i cant wait to ride it now that i've brought it to the mid point. enjoy and let it snow!

Did you have the shock revalved? This is a MUST with the Big boy spring. I am about 50 lbs. heavier than you, and could barely ride mine with the stock spring and valving. I switched out my front shocks with GYTR clickers before I ever rode it. Like these a lot, as good as the Ohlins I have on my Viper. I am running Slydog Powderhounds with 8" Bergstrom Triplepoints. Stock skis were good for trails with the same carbides and a 1/4" shim under the back of the ski rubber. Changed to Slydogs for more flotation AND sharper turning. I run the transfer rod 2 lines toward minimum and it greatly reduced the pitching fore and aft when entering and exiting corners. Goes like stink on the trail, and is asequate offtrail. Any other questions, just ask!!

What kind of set-up probs are you having???
As ViperDave mentioned the shock revale is a MUST w/ the higher rate spring. The shock can not keep up with the new spring.
As for skis I have C&A XT's got-em from Richmotorsports. CB carbides. This works well for me. The XT's are a little harder to turn at slow speeds on packed snow but in the pow and chwdered turns they are great.
I also have the high rate spring and have the shock revalved. Totally diff sled. I can pound the mougles all day and never bottom. I go 280 w/gear. I have the shock on the 3 c-clip and can run the ra in any position and never bottom.

I have had the shock revalved the suspension works well but I get a tone of ski lift in the corners. I didnt know if any one is pulling the limiter strap tighter or what.

Yes you can pul th limiter straps up a notch. This will create more ski pressure. Also the a-arms in your front suspension should be parallel to the ground. Normally people have them so they are angled up to the sled a touch.
To do this back off on the front shock springs. The nuts. You may also want to try a larger sway bar. But start w/ the arm adjustment and the limiter starps.
Just a though here. If you are new to the 4-stroke. Be smooth with the throttle. Go into the turn on the gas and keep the same throt pressure. When you whack the flipper comming out of turns you will get ski lft. Also where do you have the transfer set at?? If you are looking for cornering keep it to the minimum side of the settings.
Do some adjust ments and RIDE!!!! Put some miles on it before making other adjustments. Small changes at a time will make the best improvements.
Hope this helps

Adjust your front shock springs to the lightest possible setting, making the a-arms almost flat. This will help stop inside ski lift in the corners

question about adjusting the front shock springs- do you adjust them so the a arms are parallel with the rider on or off the sled? i would assume rider on, but i know what happens when i assume....

one more question- how is the limiter strap adjusted? i weigh about 190 with gear on. where would i want to set the strap to?

Pull the limiter up one or shorten it by one hole. Place a 2X4 under the front of the track, this will put slack in the strap and allow you to tighten it. As for the shocks, Raise the sled off the ground, loosen the rings until the springs are loose then tighten them one to two turns, just enough to keep them from flopping around when you lift the skis off the ground. Make them the same from left to right. As for transfer, I would set it as one to two less than min. this will give you less transfer and keep the skis on the ground, also allow you to spin the back of the sled around a corner a little if wanted. Start your front compression at min, if you bottom out raise it up, the same for both sides.
