Vixion kit + jettings + stock pipe= COMPATIBLE?

[DreaderX]

I recently installed my Vixion kit and bigger jetts. I have a stock pipe.


It all fit well but when i revved up the throttle it sounded something like....uhm how do i state it....it sounded like as if the choke lever is turned on..


My mechanic changed the carb settings and also the accelerator pump..

but still, nothing worked. we couldnt find out what the problem was. maybe someone could help me with my problem...


maybe there's a specific setting for this?

please help..


what do i need to do? without changing my pipe?

shave the block 0.5 mm, change the cam (is it stock T135 or Vixion's?), check the plug first

 

[DreaderX]

shave it you mean squishband? yes its the vixion's cam.......what do you mean plug? the spark plug?.....

 

[King.Leoric]

stock pipe diameter is too small bro. Change it to bigger diameter ^_^

 

[DreaderX]

any other way to solve this problem?

 

[traxxas-modifier]

what specific mods your mechanic made in your carb?

 

[goff_d_p35]

It sounds like your restricting the exhaust flow out by keeping the stock exhaust. Your 150cc is bigger than stock 135cc, their for you need a bigger exhaust flow. Find a Vixion exhaust or get an Open Exhaust like the NOB1 AL.

Try checking your sparkplug color. An experienced mechanic should be able to identify the problem seeing it.

Changing bigger diameter pipe/header should be the second step.

no other mods done...we tried to change the carb tuning and also the accelerator pump...but nothing happened..

 

[traxxas-modifier]

check the spark plug for color.

also i advise to rejet your carb

pilot jet from #20 to #22.5
mainjet from #105 to #107.5 or #110

those are already my jetts...

i removed the air filter but i guess there are consequences to this..

but for the mean time ill just leave it removed...

what would you suggest??

it did solve the problem...its running okay now but what about the objects that might get into the engine?

@dreader : that means u got too large size of main jet/pilot jet.. depends where the blurrpy happens on what throttle position.. my suggestion.. revert back first to stock jets and accel pump setup.. run the bike a few minutes.. see whether there's any hiccup or not.. stop.. then check the plug color.. if it's red brown then u dont have to change to bigger jets. i for got to ask.. why in the first place u need to change to bigger jets ?

if its ok now without air filter, then get aftermarket airfilter that can
make your engine breath freely and safely..

hmmm...i miss the silent sound of the stock muffler...is it ok if i install it back eventhough my bike have been upgraded?..what could happen if: for long distance rides n what if i "blast" my bike(ride aggresively) when using the stock muff?

Up for this thread.

I have a stock pipe and I had the tubing changed to a diameter of 1 and 1/8 size ( for nouvo/mio 150cc ) The engine can breath better.

ive tried this onced coz i miss that quiet stock sound ...God i thought my engine would blow..and the heat that the engine is generating is too much...its really not advisable to use your stock pipe when you have already upgraded your engine ( block,cams,carb etc etc)

When are you going to modify your stock pipe? mine sounds like a stock scooter ha ha ha.

I can't go strolling in PASIG area anymore with yypang shorty installed to my sniper because of the ordinance of loud and open pipes there. So I have to compromise a little in performance and use a modified stock pipe.

I am wondering what would be the suitable jetting/s to use?

try changing your cdi into racing cdi. because the stock cdi has a limiter
