It is best to disconnect it to eliminate it

Thanks! Will do!

Hey guys,
Sorry to bring up an old thread.
I know that this topic has been talked about.. But I haven't found the answer yet, redirect me if it's here.

I have a stock ace 125 with the EGR still intact. My question is.. Is the little white thing attached to it supposed to be puffing air or exhaust?? Into my left leg? I'm just not sure if it was supposed to be attached to anything else.
Oh and if I bought a blanking kit and remove it will I need to re-jet or tune at all or will my bike run fine without any other adjustments.

Cheers

no rejetting needed. this part does not improve the way bike runs at all. it should allow air to enter into exhaust while bike is drawing air fuel mix into motor therefore making exhaust gases "leaner" on hydrocarbon content by dilution. it does not let exhaust gas to escape from white bit and the nozzle thingy is a air intake . it is not a true erg system as that stands for exhaust gas recirculation . all that happens is the little black hose gets vacuum from intake,turns on air tap to exhaust which draws in air from nozzle into the exhaust pipe through thicker black pipe into the exhaust port via steel pipe with flange on motor side. this air also triggers hydrocarbons in exhaust to have more free oxygen  so they go through a secondary burn in the exhaust header. these gasses then pass through a catalytic element(platinum corrugation after header ) and further reduce hydrocarbon content. platinum causes a reaction with gas and glows red hot without flame .this is all nice and would seem a good thing except that this restriction causes a loss of almost half of the engines usable power.

Thank you for the info, always good to know what the parts actually do haha
it does not let exhaust gas to escape from white bit and the nozzle thingy is a air intake .
Hmmm... Well there must be something wrong with mine because it is blowing air (a lot) out of the white nozzle with acceleration. Enough to feel it on my leg whilst riding!  Any ideas why this would be happening?
I'll try post a vid of it blowing a tissue or something to show you the strength of air.

Will I require rejetting if a get the straight through header from ooracing?
sorry for the silly questions, first bike everything is still very new to me.
cheers

if it blows not sucks  it means that the exhaust is so restrictive  that the valve is an easier escape rout for exhaust than the pipe and back pressure is coming out the nozzle... when you order oo's pipe , order jets to suit  .you will find a large increase in power ,better idle and easier cold start. not only is the catalytic converter restrictive but the bends in the original pipe are double walled causing inner pipe to crush and cause more restriction too.  so change jets , replace pipe and undo bolts holding little steel right angled pipe and put a plate under(behind) flange to block the egr if you don't want to take it off all together.
this will increase your power nicely. put on a new muffler from ebay or oo. and enjoy a good  more powerful bike...next step after that is do the barrel , piston ,head from oo(150cc)  change front cog to 16 tooth  and look out , you have a great bike.

Sounds like a new exhaust is needed ASAP ;) thanks for the response.

Front disc is warped. Has been from new but with new FA165HH pads I am noticing it more.

Went in to shop to get a new one under warranty. The new one was worse! So I stuck with the original. There was another Ace in for service and it had a slight warp too. They are NZ$40 retail, think that may say something about the quality.

With normal use it is unnoticebale but braking lightly and just coming up to a gentle stop I feel it pulse.

Anyone know what other manufacturer may have a disc that will fit?

metal gear in australia do after market discs, maybe if we sent them a stock disc to measure up they might be able to do one for the ace that would be better quality.
