no header?

[Ridin' Jesse]

i saw a guy riding with no head pipe on his quad...i was wondering is that bad for the quad? if its not does it lower power? i was j/w

[m250r]

:huh :huh :huh :huh

He was riding it on purpose or was it like during a race or something and it just fell off?

[Scro]

im sure if debris or whatever got in there it would not be good

[m250r]

if i were you I would have just walked up to him and just like punched him in the head for being so stupid

[Ridin' Jesse]

he wasnt racing he was just in the woods where i ride and he had no header on

[m250r]

WOW! Not that it even matters but what kind of quad was it?

[400ex28]

wouldnt it be like reeeeally loud???? :huh

[Ridin' Jesse]

it was a little blaster..and yes it was realllly loud...it sounded pretty cool lol

[Toadz400]

That engine's not going to last one, mainly because it's a Blaster:p .

[Chef]

So was it the back part of the exhaust or the expansion chamber part? I dont think it would even run without the pipe on it...that is a big part of a 2 stroke.

[sam the brave]

it will worp the valves

[exatak199]

yaa it would for sure burn up all the valves that the blaser doesn't have:ermm:

and yes a 2 banger will run with out an expansion chamber not very well tho. I had a old 197? yammy 80cc 2 stroke and the one day the spring on the pipe came off wile i was rideing and i had to drive home with no pipe, it was loud and no power band (bout half a mile out in the back field)

[BUILT TO RIDE]

yeah man, two strokes dont have valves... There isnt anything to warp, or burn up. the only thing in the top of the head is a chamber.

[frosti108]

if a 4 stroke is run with no header, it will definatly burn up the exhaust valve(s)

idk my 2 strokes but thats what will happen with a 4 stroke lol

[I-7]

If the guy was doing it on purpose... then hes an idiot. Its an open entrance into the motor and its not good for the motor at all

[The grey ghost]

what will it do if i run a header but kno back pipe?

[m250r]

it will sound like s**t

[UglyMotha™]

this has been an enjoyable thread :huh

[Ridin' Jesse]

[The grey ghost]

what do you think

[m250r]

When you're taking ur back pipe off then you can take the airbox out and the carb...i heard its better for the quad :rolleyes: :rolleyes:

Yeah, take off your airbox and air fliter while yur at it, It just adds weight and slows the air down. :huh :huh

[Toadz400]

Might as well take your engine out too! Just extra weight on your frame, a kid at my school thinks his Banshee frame is pretty sweet! :huh (true story).

Well gee, I never thought of that one before, go try it out and tell me what happens...

[nhs333x2]

i will have to dissagree about no valves on a two stroke. They are power valves and they work with the exaust for your power band. To finish this, that guy needs beat with a rather large blunt object.

[speedy400]

what would happen to the motor? rings would fry, itd also run really really crappy because most the fuel and air isnt being burnt, just going right threw..... kids these days.-darren

Not all 2-strokes have powervalves. The Banshee and Blaster don't have powervalves, neither did the 250R. That's an aftermarket option on those engines.

[LazeR]

There is also reed valves, but thats before the air gets to the motor, so i doubt to much could happen to them..... Everyone who thinks its ok to run without a headpipe, or whatever, try it and please tell me how it works ? I've been wanting to know :rolleyes:

What the heck?:huh dude there are no valves in a 2 stroke. tHey have reeds. The "power valves" your talking about are exhaust ports in your sleeve. ports not valves. I also dont think it would hurt your engine to run it with no muffler. Is it gonna burn the valves? Maybe. Why? Running to lean. If re-jetted it would be ok. We ran race cars and go-carts for full seasons with straight pipes on them and no problems. You would loose back pressure and it would sound stupid loud but people run race engines all the time with no mufflers.

::Cough harley pipes Cough::

[nhs333x2]

Well every Dirtbike 125/250 i have worked on that where from 92 and up had them. Check with a professional, they could set you rigth, as for banshee and blasters, i never got to play with the engines to see. I know they are there because my freind broke one in his rm 125.

[440ex2001]

I am a profesional :) but i also know i dont know everything and i learn something new all time. Power valves are new to me.

The ONLY factory quad to my knowledge that had a powervalve system was one or two years of the suzuki LT250. Yea, dirtbikes have them, and guess what, they also advance at a MUCH faster rate than quads do...no matter what. The manufacturers, until lately, just havent really cared about the quads. I know for a fact factory Banshee cylinders dont have powervalves...I own one.

[wvspeedfreak]

The Kawasaki tecate-4's had factory power valve cylinders but they were only made for 2 years.Other than that I don't know of any others.
