why do you like them out? cause it makes you louder? Put them back in so people dont think you are a nuissance to the community.

[MotoX3]

disc systems like that run like crap without discs anyways...you have no low end

[99_300ex]

no around my community it dosent really matter ppl dont care.

That is not true, the whole point of the discs is to change power increases. Adding and removing them changes your gains and whatnot. How does it run without them? Does it preform any better then with them? It will not hurt your motor running without them. But if there are no preformance gains then theres no point. So its really up to you. Good luck.

Its 4 stroke dude, the more air that can flow out without restriction is better, you will have to rejet if you take them all out.

if you can see through it, you can just call it a straight pipe, it wont hurt the engine at all, it just sounds like an animal, it roars! i did this on my quad you just have to rejet! its awesome

[99_300ex]

pvt. maggot i think it feels like it pulls a lil harder w/o them and thanks on your input,dierwolf i see what your talkin about and thank you also.

i was thinking that the discs did something with back pressure or something is this true or does it not matter sry for all the questiosn but im always worrying about my motor.

I left all the plated out on my dg for a couple of runs. It wad hard to tell if there was much of any power gains I just know that it was loud as hell so I put them back in!

[zeppelin]

make sure to rejet though, you could be running so lean that youll fry your rings, i personaly wouldnt do it be cause youll loose back presure and bottom end power but what ever floats your boat

[DeerNuts]

You only need to worry about lack of back pressure when you run your motor with only the headpipe/ no headpipe. The issue isnt harming your motor (unless your lean) it comes down to sound. Dont piss anyone off, and as long as your happy and jetted properly, your fine.
