Alright so I've heard of what the mags say I wanna know what you guys say. Has anybody tried them yet and on what how much difference did they really make?. Also you know how in the adds theres that fin in the middle does that fin stay in that postion or does it move? I'm thinking of trying it on my '03 kx125 but I don't want to throw away a $100 so lets here what you guys think.

Matt ive had it on the 03cr125 for some time now but the weather has not let me ride. As it will fit both the 03 kx and the 03cr 125's it will be interesting to see how it performs on both bikes. I will post on how it feels on the track and then dyno both bikes with it along with some other mods also. Come on spring!!!

thanks for the reply Steve. I saw one of the mags. did a dyno on the cr with the power now and they noted that they had to lean the jetting out. why is this. Please help I'm no alstar mechanic.

The leaner jetting seems to be the trend with the PN but I don't feel anyone has come up with a solid answer on why just yet. When i find out more I'll let you know.

This product seems to produce results similar to the U.F.O. slide insert that I installed in my round slide carb. With this installed I went from a 50 pilot to a 25 and raised the needle one notch. This tells me that due to the increased velocity of the air (less turbulence) it tends to pull off the needle jet/jet needle circuit a bit more. I would think it would make the transition smoother due to the increased overlap and increase throttle response. Just an idea!
