alright well i got on my 450r today and i went to floor it and it reved up real high then bogged out and went, put put put put put then stalled, and it kept on doing this.

do you think that there might be water or somthing in the carb?

is your air filter clean :-\

Hows your Gas? Old?  Put some fresh 93 Octane in it :-\

*Clean your Air Filter & AirBox*

try 2 change your plug

ya if it's not starting back up its probably the spark plug thats the first thing id try.

Was it warmed up and everything, and does it have clean and enough oil in it?  Is the fuel percock on?  Is the choke on?  Check the plug too.

my gas is fresh and my filter is clean and i just put new oil in it, my dad thinks there might be water in the carb? :-\   but ill try a plug!

Water in the carb is sometimes as easy as just draining it, it'll get it out sometimes.

Will it idle? Does it bog when you give it gas and the shut off? If so I would check to see if the clip the holds the needle is broken. When you give it gas the slide will come up and the needle will stay down, choking it out.

AHA!!!!!!!!!!!!!!!!!!!!!!!!!!!
NOW YOUR BIKE ISNT WORKING!!!!!!!!!!!!!!!!!!!!!!!
thats what ya get for makin fun of me ::)
















Dont it suck, i hope you get it fixed fast, Could be a dirty carb, I'm no expert though, hope its an easy and cheap fix!

alright, i got a new plug in it, and it is still not working.

yes 450r racer i give it gas and it goes put put put put then dies!

how too i drain the carb?

Check your muffler bearings sometimes they cause that or your cool start by-pass check valve in the radiator could be acting up, flush it out with some gator aid high endurance or some red wine.

ya ill get right on that eric ::)

It's not your plug, it's not your exhaust...

it's either a fuel issue, or an air/fuel mixture issue.

Put your petcock in the reserve position and try that.  If that doesn't work, then I'd drain the carb.


Good luck

did you leave your air box lid on after washing it, sounds like something stupid like that.

This may sound stupid Josh but I ran mine with the airbox lid off and it did the same thing. With the stock jets it runs like crap when it gets too much air. Good Luck!!

Of course...

It could be the Fitzer Valve. If that's the case, you'll need some 30 weight ball oil and some ball bearings.

If it revs up real high then died that is a sign of a really lean condition then since it's so lean it runs out of gas hence the bogging and engine stopping. Basically what you did is burned all the gas that was in the bowl. Correct me if I'm wrong but don't 4 strokes have some type of electrical gismo conntected to the carb kinda like a fuel pump. I read that on a site when I was searching for a carb for my 500. If there is something like that then my guess is that it shorted out and didn't feed carb enough fuel.  -Mark

does it do it all the time hot cold or after it sets

clean the bowl on the bottom of the carb. my friends 86 250x does that too. the gas tank is so old it gets stuff in it all the time. we put a fuel filter on it and it does a lot better. anyway check that. if there is stuff in there clean it out and get a fuel filter if you dont have one. it is only like 4 bolts on the bottom of the carb on his.

i had the same problem with mine about 3 months after i got it, i just cleaned my carb and cleaned out my tank(there was stuff in both) and then it ran perfect, mostlikly whats happening is when u go to rev up it sucks something up into a jet which inturn kills it, just make sure u always get good gas and never have anything in it, a inline fuel filter wouldnt hurt either

i read somewhere that the tanks have a filter built in the pet thingy. :-\

any way. i think you need 2 rejet it josh. i pulled that plug out and it was BLACK!!! plus before i pulled the plug out i jabbed the gas but the plug was dry.  :-\

they do, but it only filters out larger things, small stuff goes through it, i had like lil black specs of dirt or something in mine  because the gas station had a bad thing of gas, a inline filter keeps most or all of that out, mine has been runnin perfect ever since i cleaned out my tank and carb

already borke this one to?

shut up tom how bout you learn how too ride before you talk crap about me.....your brother who has been riding for 1 month or less is already 3 times as fast as you....wait the mini quads are already twice as fast as you....so sut up fat azz

ok josh, chill out alittle, ryan def isnt faster than tom....ill back him up on this one, and i would be pretty pissed if u came to my house when i was gone and rode my bike

ryan???????

ya exaclty

where did ryan ever come into this? and maybe i only rode it cause rob said i could!

thats why i said ryan???? i think you mean robbie alan. ;)

sorry thought u said ur brother


ill hand it to robby, hes gotten alot better! but hes also on a fast bike and has gotten more seat time, but oh what do i know right?

umm one question josh.....does robby own that bike.... no
does rob work on that bike no... robby doesnt really work on his bike himself either i do alot of it... and it doesnt fall apart.....

ok ok children calm down!

ya eric lol get in there and supervise this  ;)

wait tom fall apart ughh umm i do belive at bartow i had to help you fix your bike cause the rear end was falling apart.....

wasnt that after u rode it? lol sorry josh had to  :P

Yeah I need to with all of you rugrats ;) You guys better hurry up and make up! I'd hate to have to send you to the corner lol

ya since doing 3 laps would of done that!  and tom rode it after i rode it!

umm u told me what the part was called then sat dwn and had a drink and i was iin the sun for a hr gettin it out and bending it back... u can ask alan he saw it...... u hit the pin with the hammer then put it in backwards.... so that was soooooo much help makin me do it again.!!!!! thanks

OK CHILDREN STOP AL THE COMOTION. THE MAIN THING STILL IS JOSHES BIKE DOESNT RUN OK. :P

yea a half a lap b4 the double..... then i relized o its messed up....

tom you had no idea how to fix it, when i helped we actually fixed it, and u didnt even bend it back, bing did

i just think that his whole arguement is about tom being unhappy about josh riding his bike, but back to the thread, josh i think ur problem is the gummy bear i stuck in ur intake that night u were being real mean to me, i figured u would have noticed it wen u did some adjustment to ur intake  ::)  :D

no but i did happen too see the publix bag :P

funny lol, but im still trying to get he point across that doing that was a bad idea....could have been really dangerous if i would have cased somthing that day  :-\
