my bike ran good UNTIL....

[Overboost]

ok, issue...

 

bike is mainly stock, outside of timing and pro circuit pipes.....

 

stock reeds and TORS topped carbs, stock air box, KN filter cut lid...bike would pull hard, pull wheels off ground easy and no issues

 

I changed carbs to stocks with TORS removed, VF3 reeds, pod filters and rejetted 320 main, 25 pilots.

now, it has major bog off idle and no matter what will not pull wheels off ground now, at all

 

so I rejetted to 30 pilots, 350 mains...same thing, no change?

I am sorta lost here, ran perfect until I changed carbs and reeds. I know pods wont make that much difference but I did jet up for them.

 

an input or ideas. I am going to put it back to previous setup and go one at a time.

prior jetting was 290 mains and 25 pilot, ran perfect

Make sure you didn't put the slide in the wrong carbs. Also check to make sure you put the choke tube on between the carbs.

first thing I checked, runs good, so tube is in place, and slides have the taper in the front, it just has an issue when you rev it sitting...(bogs then catches up) and dont make any power....when in gear and rolling....

 

if I mess with the air screws the sitting bog gets better, but I went from 25 to 30 pilots and it is still the same...

 

could the reeds cause this issue? stock reeds and stock carbs, fine..I change both, then I wind up with these problems...

thats why I will just put it back and see what happens.

25 to 30 pilots is a BIG jump in stock carbs.

Even with pods, I'd bet one turn out on the air screws and 27.5 pilots would be fine.

Also make sure your carbs are sync'd.

 

If they're not in sync, it'll cause it to run like crap off the bottom.

reason I went from 25 to 30, in jetting faq, for the pipes, pods and reeds, recommends, 1 each, so I thought 2 total was good.

the farther I turn in the air screws, better it runs which says I need bigger pilots.

but still on the rev and trying to pull, it hits a wall, dont pull anymore, just stops, no pull I can hit 3rd gear in my yard when I used to only get to top of first, while riding a wheelie across the yard.

 

I lost power somewhere, it must be a jetting issue.

or I just have junk carbs and my bike dont like VF3?

i have stock carbs, rocket pipes, dune/trail port, cool head with 20cc domes and k&n pods at 1100 ft. and 60 degree average i am running 27.5 and 320 mains. i see your about the same elevation as me. to me the jetting sounds rich for just adding vforce 3 and pods. i would go down in jetting 300 main, 27.5 pilot. did you buy your vforce new or used? how is the reeds on them. make sure they are clean, no cracked edges and seal good.

[James-26]

After you removed the TORS did you unplug/cut the black and white wires under the gas tank?

[Overboost]

I dis-comboobulated the tors before I did anything. it would stall when you let off clutch slow, but ran great when you revved it up and rode it hard, that ended up being a bad clutch

 

I just added things from my old bike to this one, and it dont like it...

I moved it all over from old bike that ran good until it lost a seal in the engine and smoked because it was pulling trans oil into the cylinders....

putting it all back to normal tomarrow, see what happens then.

 

just discouraging. do all that and then it dont work correctly.

Most bike that are running stock carbs don't need more than 27.5 pilots. My wife's bike with pipes and an open air filtr runs 27.5s, my bike with a cut and chambered head, dune port, pipes, timing, ported reed cageswith Boyesen reeds, and +4 timing, and carbs bored to 28mm runs 27.5s also.

Your jetting is way off as said before, you do not need any bigger than a 27.5 pilot.

350's are way to big.... im running pro circuit pipes, bouysen power reeds, +4 timing, k&n with proflow no lid, and cool head with 20cc domes and my jetting is 280- 290 depending on temp.. so i would start dropping sizes and see if it improves

im in lansing mi runing t5s +4 timing pro flow with k/n in box lid off bouysen rad valves stock carb needel 4 up from bottom boss in takes no cros over 300 mains 27 .5 2 turn out on air and acool head 20C domes runs spot on id go with the pilot and air screw frist just my 2 cents

[shee2000]

i live in saginaw and im at 27.5 pilots n 310 mains. with pods,chariot intake built in crossover,+4 timing,22cc domes,tors gone,and fattys

I read over the part of you having an air box with the lid cut, my fault.

280 to 320 is where you're going to end up.

 

I still think your carbs need to be sync'd better or there's dirt/debris in the carbs you have.
