no torque/boging off idle

[1966nova]

its hard to believe my buddys banshee with JUST fmf and shave head only is VERY raspy feeling and super fast on his throttle

compared to mine it feels like a four stroke throttle down low .......

yes i did i changed the jets to 290 today no better i have some red needles the kit came with try those???by looking on inside of carbs they appear to be sliding both the same... use factory middle clip on needles?

 

also what is the +4 timng plate do more low end it should have made a diffrence right??

 

with your head shaved and new top end,... +4 timing, and pro circ your bottom end should be frikin great! your jet needle and main are controlin 1/4 throttle on.

[1966nova]

so really the red needles in the kit jeff sent me doesnt really change much???? should i physically remove the pilots and check for blockage?but it does idle good though

[Screaming Yellow Zonker]

when did mains begin to effect idle off idle response? mains dont really effect anything till 3/4 throttle.

 

If the main is too big than it will dump fuel.

Do you know how a main jet works?

The needle is going to make a difference. The stock needle will dump fuel quicker. The new needle will allow the fuel to flow gradually. Yes the middle clip.

 

You will loose a little down low with +4 timing but it wont make it bog.

 

I am running 3 1/2 degrees and still have good low end. I am also running a 340 main with a 27.5 pilot.

i also had vitos carbon reeds on it and took them out tonight put stock ones in and it seems to be more better on topend so i guess reeds didnt help any performance??

 

 

 

i also had some problems with one carb leaking out fuel from the bottom hose? with the fuel valve on i have checked float settings are good ive cleaned it and tightened the screw and still leaks very slowly would that make it bog ?????

uhm, no fuel is going to dump at all if its frikin closed. the pilot is the only thing working until transition into the needle at 1/4 throttle. the needle is still in the needle jet until about 3/4 when the taper is out the the needle jet and main transition to the main.

if they over flow then your bowls are set wrong. hold em upside down and measure 21mm from the bowl matting surface to the top "bottom" of the float. sometimes they will leak if you leave the petcock on while its sitting though.

check to see if ur airbox has the rubber snorkel on it if it does remove that. that snorkel thing does that to my bike if i put it on just take it off i know this sounds newby but infact its true.

ive measured them before there within the spec in the books and the drain screw is clean and tight,,, that wont make the bogging feeling would it??? i guess tommorow ill change the needles and physically remove and clean the pilots i guess and see what happens??

[1966nova]

i dont have the airbox im using 2 k/n bolt on filters

If the floats are adjusted properly, and the carb is still leaking fuel out of the overflow, then the needle, and seat above the float is either dirty, or needs replaced. The needle, and seat being dirty, or worn out, will cause one side to be very rich, and you won't be able to adjust the carbs, and make it run good. In short, yes, the carb leaking fuel out the overflow hose will make it run like shit. Another thing is, FMF pipes like a fatter pilot. Try a 27.5 or even a 30, but you must fix the fuel leaking out the hose first, before anything else will help.

How do you know it is at 1/4 throttle? so than all needles are the same is what you are saying!

 

the needle and pilot are set up like a hole and a plug. When the needle is down very little fuel will get by the needle. As you give it more throttle you get smaller and smaller on the needle. when that happens you start receiving more fuel. It is not until the needle is all the way out that you are using 100% of the main jet.

 

 

 

I would take the pilots out of the carbs and make sure those are clean or even put the 30's in. I would definitely put the red needles in.

doesnt have to be exacly 1/4 that depends on the clip position. why are you f`n with me, all I started this with is mains DONT effect the bottom. go walk into a knife. yea I was born yesterday. I dont know how they work your right!

[1966nova]

i just checked my pilots yes there 25 and they are clean???

so i guess ill try the 30 pilots i have in the kit and use the red needles?? what about air screws set them about 1-1/2 to 2 to start????????????? dam im puzzled about this bit**ch i hope these needles will fix it or the pilots

You need to fix the problem, with the fuel running out the overflow hose, before doing anything else, or you will end up doing twice as much work.
