Buy a race chamber from me, ask FM to mount it and show you immediately what they say it right without alter anything. If show what they said is right, i provide you a Alu silencer free! But take note ohh...my pipe is illegal oh...

oh.. you are answering the questions

 

changing the air filter got much help?

[rumpshaker_23]

Im running without air filter. It feels lighter. According to mech at FM, he say sg roads not much dirt unless u goin off road. anybody running without air filter?

[Sorrie4u]

yea i've heard running without air filter is alright in sg and more powerfull but after u took out the air filter then the AF ratio will be messed up so gotta tune the bike change the jetting n all that i suppose...i read that in the earlier posts from the pro aprilians...im very unsure thats y wanna make sure here lei...any pros can help? and is the original air filter for rs125 that expensive? 90bucks?!

[tknge]

I had been running my bike without air filter for 12yrs, no problem for 34mm carb as it came running rich. For 28mm Carb, not sure. Best is you have to check your plug condition and determine to re-adjust you AF.

[d3rRiCk]

i been running filterless too... no problem for mi. oem filter i dun know how much. the price of 90 is after market filter.

[Sorrie4u]

ok i will go take out the filter soon...can take out by myself de right? so i can keep the filter if need to put back next time...any effects on the fc? no need mech to take out right? jus unscrew 4 screws then take out everything inside can le har?

 

but if taking out the filter means more air go in then jetting all same...then most likely will run more lean right? the AF ratio? and it will lead to seizeure running lean??

 

anyone got the website with pics n descriptions for plug reading? and an accurate plug reading can only be obtained after u did a plug chop??? plug chop is running the engine at high speed then switch off the ignition right?

[lycan]

my airbox in side only got a 4 grid thing.. is that the filter?

[Sorrie4u]

hmmm i think should have 2 sponge like thingy inside right? then the 4 grid plastic thing is the seperator for the 2 sponge filter...im not sure too saw pics but never take out mine to see yet...

[rumpshaker_23]

my airbox in side only got a 4 grid thing.. is that the filter?

 

nope. da grid thing is to support da filter. so there's no filter lor. anyone disagree?

[Sorrie4u]

hmmm i change my gear oil to fuchs pro srg75 gear oil liao...and spark plug to denso iridium IW27... will give some reviews soon ^^ and the filter i decided to leave it inside la...since i see it is still quite clean...maybe when it comes to 10k mileage then i take out and throw awy and run without filter...now onli jus turn 6k mileage nia...omg i love my bike! haha!
