Took the 400 out for a good trail ride today and again all I can say is wow!!!!I putted it around a little off idle hit the gas to wheelie over a hole bang it was there.Run with a 400ex on the road and he could wheelie his but I took him all the way.Climbs hills great no kind of a bog at all has power from the start to the top.Hung it up in the mud it rocked and powered its way right outt. I cant understand why this pipe isnt pushed like the others.This pipe really rocks.

 

So Brad. Tell us what you really think.[img]i/expressions/face-icon-small-smile.gif[/img][img]i/expressions/face-icon-small-tongue.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img]

 

I have told lots of people that I really enjoyed the dynoport. Rich Daily deals with snowmobiles and they are basically the same thing.

 

Anybody have a dynoport pipe for a concentric 400 Scrambler they would be willing to sell? PM me or my email is Fourwh8863@aol.com

 

Still looking [img]i/expressions/face-icon-small-smile.gif[/img]

 

yes,the dynoport was the second pipe i bought for my scrammy
late back some years ago,great friendly tune,but it only work
on a stock clutched setup and doesn't like to rev past 6000-6300 rpm,
but yes it is actually very impressive for it with no flat spot
at all considering the the low range it of revving it produce,their
sleds pipe are very respected also.

 

I got it to work best with a Dalton blk/white primary spring(close to a polaris green) and a Aaen blue secondary. Which is close to stock but better backshifting.

 

I'm almost positive now that I'm going to get the Dynoport. I already have a green spring, so I may use that to start with. What do you guys think of running a green or purple primary spring and putting in a set of S-58 weights in it? Someone reccommended it, just wanted to get your guys's thoughts. I've already got a HPD violet secondary in, which is pretty much the same as the AAEN blue.

 

I would start with your green and violet springs and stock S55 weights and then try the S58 to coompare which you like the best.

 

no in hell you will pull s-55 weights with that pipe,or lazy response
is what you looking for,stay stock weights,the violet secondary is not
a bad idea depending on what shims you put behind the snap ring.
