okay i moved my uni pod filter in the air box and took it mudding when i was there my friend crashed and so i only went through a tiny mud pit. we stopped for a minute and i turned my back back on and it started fine but when i hit hte gas the throttle was like grinding but ran fine.

I go the blaster home washed it and then started drving it around when i gave it some gas it would boggg and then take off again so i changed the plug cleaned the carb and changed the fuel filter. nothing adjust everything nothing changed.

So i took the reeds up to a mechanic to see if they looked good he said that he though they were ( i already ordered new ones) and i was like sh*t so wtf now.
BTW it has always ran a little rich. So i clean the carb and i look at what size the main jet is and its 230 isnt that small for a pipe and a filter? but its always ran a lil rich. im confused and have no idea where to go from now ?????????????????????
 
where is the pilot jet
how do i know how what my need is set on and where is it?
im blank on workin on this type of carb
 
when you said grinding, that probley means that mud and water got into the carb and the carb slide. when you cleaned the carb did you notis any dirt?? did you clean the slide?? and also clean the air filter and intake tube. and if water got in the carb and intake then its probley in the crankcase. as for yor jetting what makes you think that it was running on the rich side?? what is your altittude??
 
fuel filter is located between the shut off and the carb

and no dirt really it was pretty clean and the slider u could see black where it had rubbed on the inside of the carb. Is that wierd?

Also the plug has always been black and a lil wet
 
a fuel filter?
mines an inline one idk yours is newer could be right off the tank or something lol
 
well..... blasters dont come from the factory with fuel filters. my carb slider has a couple rub marks too, but if its 2 much then i would make sure its installed correctly. is the throttle smooth again?? as for the jetting that is odd, how many turns out is the air/fuel skrew?? do you know your elevation??? was there water on or in the air filter??? (just trying to get all the info man)
 
air screw 1.5 out i think

there was water on the filter yes but not anymore and it still does it
and idk bout elavation i live in missouri if that helps lol
 
im thinkin that water is in the crankcase still. you could try running it, to dry it out or flushing the crank out a few times. have you tried doing plug chops??? with your mods it should be on the lean side.
 
What kind of grinding we talking about. Did it do it when you was idleing, taking off? Also this may sound stupid but hows your chain for adjustment, they can grind if they are too tight/loose.
 
it was the throttle it was stiff and it wasnt the chain lol

i think im gonna try new reeds and diff jetting wat size do u think i shuld be at?
 
what size jettin should i run and i have boyseen dual stage power reeds dg pipe (crap) and uni air filter and boredd 10 over wish it was more but thats it lol
 
The needle, as it sits in the slide of any carb, is slightly loose - just the way they are by design. Some needles are held in by a small spring, some by a clip, some held by a small arm and a screw. But all of them have the ability to move just slightly.

This movement (especially as the carb gets older and starts to wear) allows the needle to rub against the inner wall of the needle jet (the brass tube that the needle slides down into and that the main jet screws into from the bottom of the carb - sometimes called the emulsion tube).

What happens over time is that the needle will eventually cause the needle jet to oval out, changing the jetting from mid-range on up towards the top end (not as much on top end though, as the main jet limits the maximum amount that the carb will flow when wide open and the needle's not really doing much when it's at wide open either).

So, if you're chasing what seems to be a rich mid-range jetting problem and you have a old carb or a carb with a lot of hours on it, pull the slide out and look down into the needle jet and see if it's starting to oval. You'll see the ovaling on the engine side of the carb. - think egg shaped

Most of the newer carbs, along with the higher performance older carbs, have replaceable needle jets, so if yours is looking worn, just go get a new one!

You can also do more specific tuning with the needle and needle jet too - there are often options of needle tapers and needle jet diameters. It can get really deep if you're one of those racers that chases that last spec of hp.




could this be y im runnin lean i almost always run in the mid power range and my throttle grinded that one day could of grinded it into an oval and not when it goes into mid range power it gives it to much fuel and boggs out and then takes off when it burns all the extra fuel?
 
ive never heard that but i guess it makes sense. only way to find out is to change your main jet to maybe a 260-290??? and keep the needle in the middle position. when i was tuning my bike i noticed that when it was on the lean side the power band didnt kick as hard, then when i got it right, it would be a little slow in low end then hit pretty hard in the power band.
 
i know it should be runnin lean i havnet done a plug chop yet but when i put in my new plug a while back it turned a really wet black just like my last one was

and why would water in the crankcase make me bogg?
i know its not good to be in there

did you go through all six gears full throttle when the spark plug was wettish? and did you pull the plug out right away? if not then just pulling the plug off would not do anything. or help you to tell where your jetting is. usually for pipes you will go up 3-6 jet sizes. sometimes more sometimes less.

start at a 250 main and do a plug chop. then go up to a 260 and do the same.

do that until the plug is card board colored. buy a 250 main, 260 main, and a 270 main jet.


as for the crank case i can't help you
