what is it and would it be worth getting? and does it give you a claimed 2.5 hp increase?

 

It offsets the flywheel relative to your stator plate, doing this advances your timing. Your spark plug is timed to fire when the piston is in a certian position. Advancing your timing is changing this so that it fires at a different time.
I highly doubt that you will get 2.5 hp, but some might argue against that.

 

thanx for the info shavo, how do you like your fmf pipe? im thinking of selling my dg and getting that. would you say that the fmf is unreasonably loud at all?

 

No actually i find it to be quiet compared to others such as toomy and LRD. But power wise it's the best all around.

 

have you ever heard the dg? i think its loud and my dad wants me to get rid of it for when we go on trailrides and stuff so we dont get in trouble, if you have heard it is the fmf a lot quieter than it? thanx

 

I donno dude. I can't say that I've ever heard any DG pipe products. Usually on-line you can find DB ratings, check the two websites and see if they say anything about it.

 

It all depends on your definition of quiet. 2 strokes are not exactly the quietest with aftermarket pipes. I have fmf and i really like it. My friend has pro circuit, but it just doesn't have the same power.

 

well thanx for the info guys
