ok i stil have a mid range bog... it will go away once powerband kicks in but it is like spuddering like crazy before it gets there and it is normal up to about 1/4 throttle... i am stumped i have no more ideas... it still seems too rich..it will just about move with the air box lid on it wont hit powerband with it on so i am about to not even run the lid anymore...plugs are all wet when i pull them out.. my jetting right now is....290 mains, needle in 4th clip from the top, 27.5 pilot.. so today i did a plug chop and i have no ring at the bottom of the thing at all on eather plug... i warmed it up with the old plugs... put new ones in ran it WOT in 6th and hit the kill and pulled in clutch took them out put the other ones in and rode home.... here is what they look like...

look up a plug chop on here... do that then if you need to change your jets you pull the carbs out and they are in the bottom of the carb when you remove the 4 screws that hold the bowl on.. its not hard to change the jets but it is hard to get it right..

ok i stil have a mid range bog... it will go away once powerband kicks in but it is like spuddering like crazy before it gets there and it is normal up to about 1/4 throttle... i am stumped i have no more ideas... it still seems too rich..it will just about move with the air box lid on it wont hit powerband with it on so i am about to not even run the lid anymore...plugs are all wet when i pull them out.. my jetting right now is....290 mains, needle in 2nd clip from the top, 27.5 pilot.. this is the deal on what made me rejet... i bought the quad with 38mm keihin's with pod filters and no airbox.. i need to run an air box because i ride in alot of water and mud and stuff... so i put the air box in and it always ran too rich.. i traded the keihin's for a set of stockers with stock jetting... so i had no idea where to start with the jetting.. i threw them on and it ran really good with stock jetting but it always ran way better when i took the lid off even with stock jets (200 mains and 25 pilot)... so i posted everything up on here and alot of people said i am going to ruin my motor with the stock jetting... i have not done a plug chop because i have not gotten it to run smoothly.. and i would have chopped about 5,000 plugs by now if i did that everytime i tried to get the jetting right.... if anyone has any ideas please let me know this is starting to drive me crazy i havnt been able to ride for like 2 weeks now because of this stupid jetting problem.. and i have to drive an hour to buy jets aound here or order them from jetsrus and it takes a week.. i am going to pick up some new plugs today and do a chop i guess.. thanks in advance

well i started too rich and i am working my way down till it doesnt bog anymore... then once it is running right i am going to do a plug chop and see where i am... i mean towards the blunt end...

yeah i got the tube beteween the 2 carbs... but the hole it was in is on the other side like if threre was 3 carbs where the next tube would go..

anyone know???

ok well here is where i am.... 290 main jet... 27.5 pilot..3rd clip... it runs really good right now where it is except for a little bog around 1/2 throttle... i remember reading that with the vforce 3 reeds alot of people have to lean the needle out to make them run right... so i am thinking about trying 2nd clip from the top... does that sound to lean for my mods or what??

when i was rejetting i noticed a stick jammed into the carb.. it was on the right carb (not the one with the choke lever) but it was in the spot where the choke tube would go on the other side(facing away from the motor).. is this suppost to be plugged??? or could a stick just have gotten jammed into it some how..

No Porting... has normal compression.. stock timing..

so do you think that carbs are just too big for the setup??? or can they be jetted to run right??? he just need a ball park range because pilot jets get expensive when you need to buy 5 or 6 of them.. thanks

anyone have an idea of where he should be???

yeah i know they are lol.... i had them on mine at one point and they always ran wayyy to rich.. yeah thats what he has done... it is also bored a little but i dont think that makes a difference with jetting..

one of my friends is having trouble with his jetting i just want to ask what you would thing a good starting point would be for him... he has FMF pipes, boysen reeds,he is at about 500 feet.. the carbs are 35 or 38 keihin's... he thinks its a pilot jet problem he has a 62 pilot jet in there now... any ideas on what he should be running for jetting???

k thanks for the info... i am going to buy 290-310 and see what happends... the thing is with my jetting now i dont have a crazy amount of smoke.... but it still has to be rich right??

ok the jets came in... i tried 340 mains...4th clip and 27.5 pilot... it did nothing but bog really bad and had no power through any of the throttle range... so i put a 330 in and moved it back to the stock needle clip...3rd clip and it runs better still lags alot beteween 3/4 to WOT.. but there is no way i can run the lid on it right now... do you think i need to go to like a 300 witht the lid on???

ok i will give that a try when the jets come in and let you know how i made out..

just to help future people i had alot of luck with jetsrus.com.... i would have used F.A.S.T but you have to call to order them and i dont have time for that at work... but jetsrus had all the large sizes i was looking for... thanks for the help guys ...

anyone???

let me know what you think of my jetting for a starting point...here is what i have for mods fmf pipes...k&n filter with the stock lid installed with snorkel still on...vforce 3 reeds... trinity stage 3 porting.. boost bottle...32:1 mix with high test.. 500 feet this is what i am going to run 340 main jet... 27.5 pilot...needles 4th clip from the top.. i ordered main jets from 330-350 so i hope i am in the right range...

no not much around here...and they dont like to stock anything

no problem man.. thanks for the help
