the gains are minimal and if your stockish it wont affect much in front of reed cage yo uget more midrange behind it by the carb theres subtle topen gains .if you have boysen ports professionaly ported in your intake, there is a decent gain
na i m not stock i have a ported job done .i askin u dis because
since i put on the aluminium air box and use the reed spacer for my carb to be closer
my bike cuttin out on the top end when i stay too long in my last gear
i mean by cuttin out :it s doin like it runin out of gas and when i ease up on the throttle it s comin back normal but if stick the throttle in sixth gear ,close to revin out it will bug down after let say 8 second after.
i m try the test to find out if i have on the right the main jet by strechting the last gear and shut down the engine while i have the cluch in .the colour of the spark plug after dat test was brown like chocolate .so i m guess dat jet it s fine .
can i have some opinion from the elders in dat game lol
sounds like your sucking your carbs dry .. you may need an adjustment on the float or you posilbly have some sand in your filter that is attached to the petcock .. you will have to drain your tank, pull it off your bike and remove the two screws.. the filters are right there see if there blocked and it is probably a good time to go thru the carbs.. clean em.. and inspect the reeds
na dajogejr i m using the spacer cause with the aluminum air box my air boots was too short so i had to use spacer to bring it closer.
i didn t check electrical yet i will double check for air leak .
i didn t have this problem before the alu air box .
thanks to y" all
what did you have pod filters? my guess is that with the restricted flow of the air box you are on the rich side. if you had an airleak you prolly woulda broke a motor (lean conditon) i would rejet it and see what happens. i have seen bikes actually foul the plug and stall wide open in six from being too rich
the other thing that i forgot, do you have stock carbs? if you put the spacer on the carb side, then it goes from that lil hole in the carb (what are they 26mm or something??) to the big open area of the reed block, could be losing velocity, if you stick it on the engine side, it may respond better. just a thought
alright heres the deal, i think your not getting as much air or air at the same velocity that you previously were without the spacers (and whatever filter arrangement you had). since not everyone is a plug reading expert, check your main jet size, go slightly larger (next step maybe 2 steps). see if your WOT stumble gets worse (happens sooner or shuts the motor off) then you know for sure that you are WAY too rich. then you can go leaner than the baseline jet. hope that helps
