Need advice........Pro Circuit pipes, K&N

[REV-I-DOO]

Ok, here's the deal............

 

It starts on the first kick without choking it. Seems to stumble and load up when it's cold and from idle to abbout 1/2 throttle when it's warm. It acts like the pilot circuit is rich but I have the stock pilots in it and I should have to go richer with the mods......... no?

 

Here's the mods.......

 

Pro Circuit pipes

K&N pods

ported/polished (don't know who did it)

Boyesen reeds with spacers

 

Stock carbs without TORS

300 MAINS

25 PILOTS

Aftermarket needle (not sure who makes it but it's longer in length and the taper is longer and alot thinner).

 

Anyone out there running a simular setup? Please help!

[NEVER SATISFIED]

im runnin similar setup.. im at sea level .. ive got pc pipes.. ported pods and v force.. those are the only things i have that effect the air fuel ratio. i've got a 420 main air screw turned out .5 from seat and needle in stock place with a 25 pilot. runs like a champ i pull 17 front tooth sprocket with no probs bogging.

 

as for that after market needle ya got there.... sounds a little lean to me.. try going down one clip on the needle move it towards the tapered side one clip.

I'd bet money you have the dynojet/toomey jet kit. Those needles are much longer, and I've heard they are Blaster needles. Can't be 100% sure on that last part.

 

This is a dumb question, but...are your air filter(s) clean...unobstructed?

I'd turn in the air screws .5 turns out...and go from there.

 

Usually aftermarket pipes like 1 size fatter pilot...and I've read some FMF's like 2 fatter.

 

Definately sounds like you're rich...though. At least you have it narrowed down.

 

Put stock needles back in and try the middle clip...

if the toomey needle is longer it would cause him to be more lean than rich..it would make more sense to me for the toomey needle to be a shorter(leaner) needle. i dont see the point of running the toomey needle myself. i always ran stock needles with my t5's and it ran great. i would ditch those needles and go back to stock and see what it does.

Thanks!

 

I just put the stock needles in and I'll give it a try tomorrow.

Loco...let me assure you the Toomey kit/Dynojet needles are longer.

 

I have 'em. Got the kit from Magic.

Came with stickers...he he. Needles and 270 and 280 main jets. that's it. Oh, and a spacer for the needles....

 

Once you install the Toomey/Dynojet needles it's "akward" pulling the mains out, cause they're so long.

 

My shee runs fine...IF I had problems, I'd change the needle back to stock.

 

Again, the Toomey kit is in fact a longer needle. I'd go back to stock, as said...and go from there!!

 

Next time I take my shit apart, I'll be sure to take a photo of each!!

I had Pc pipes on both my shees at one time,totally different machines,but the setup was still the same.Both had K+N filter,modded airbox

 

27.5-30 pilots,300-310 mains,stock needle in the 2nd clip from top.(one notch leaner than stock.

 

Was really hesitant about leaning out the needle,I thought for sure that it would be the opposite,but it was the only way to get the middle/top of the porcelin a choco brown and eliminate the light stumble.

 

One had Pc pipes,k&n,vforce,140 psi,+4 timing,stock piston,modded airbox.The other had Pc pipes,k&n,boysen rad valve,170 psi,+4 timing,power pistons,modded airbox

 

With the exception of one size on the mains,they were setup exactly the same.

Put the stock needle back in, e-clip in the third notch.............

 

Problem solved!

 

Did some plug chops and it's right on.

 

Thanks for the help!

hey do a WOT and see if she bogs or feels like it doesnt want to pull anymore... 6th gear pinned

[dajogejr]

Glad to hear it's screaming again.

 

I've heard more bad then good about the toomey/dynojet needles, after I installed them...of course. I've had no issues with them, mine is dialed in...and plugs look beautiful!!!
