chris, my block when i looked at it....the scratch i think removed a little bit of the nicosil coating.. and to what the mech says, he said theres a "drain". but then he told me that i could still take the block to polish...maybe make my bike slightly louder thats all and maybe eat a little more petrol.

 

so what do you say..now i really have phobia for piston seizure already

I see what you mean - the scratch was a depression that would have prevented the O-rings from sealing completely. The question now is whether or not the polishing managed to get rid of the scratch completely, and if it did, whether or not it means your nicosil coating is completely gone too. If the scratch hasn't been completely been removed and there's still blow-by (the blowing - or leaking - of gases from the combustion chamber area below the piston to the area above the piston), that means you'll most likely experience some loss of compression.

 

But as long as your top overhaul was done properly, your jetting's correct and your 2T flow is properly adjusted, there's really no need to be paranoid about piston jam. That's a lot of "ifs" though.

i only know that my 2T jetting is very rich now. was advised to switch back to normal when i clock 500km. i was thinking of tuning my bike to make F.C less rich. but after a piston seizure...abit scared now... dunno what will happen the next minute.

 

when can i feel the power of my bike again :cry:

overhual seems to be the latest craze among aprilians... first chris ,then me , then vinesh,samual,andrew and latest victim shane....

 

within a short span of 1 month plus 6 RS125 overhual.....

 

our run-in outing group is now recruiting more members.... who next come come dun shy:cheeky:

hahahahaha... dun go out like dat....isa suay...all racing bikes then all move at top 70km/hr!! hahahaha... but guess i will be the first out of the league..aahhahaa... as of now...180km clocked! hahaha

 

wad happened to shane bike? i tot he long ago overhauled le?

where is the scratch located? above the exhuast port? by how much?

haiyoh....not so sure lei....i look at the cylinder block, dun even know which is which... anyway now starting to run in le.....guess will start to find out if there are any probs in due time..

 

rainy day....ride safe

Hey bro.. It's Viknesh, not Vinesh la!

Anyway, I agree.. Alot of our bikes seem to be taking a break in motortiams.. Dunno who will be the next victim liao!

 

Hey Samuel, do you mind sharing with us the price of ur parts etc of your overhaul? Atleast we'd able to compare and know where are the best deals for the cash strapped.. You say Arai helmet, which one liao? got so many, from 200plus to 800 plus..

[Sub Zero]

By the way, Mr Edwin.. Pls refrain from using so many emoticons.. I wanna quote your post and add reply also cannot!! :mad:

Andrew, why you need so many things? What happened to your bike?

If I'm not wrong, Andrew suffered a piston jam.. His 2T flow was most prob not enough as his 2T gear teeth were broken. Piston jam before he could replace it..

 

Haiz.. so many Aprilias in workshop now.. Including mine..

Aprilians, whenever anything seems to be wrong with the 2T flow from your 2T pump/tank, immediately pour 2T direct into your petrol tank to premix it with your petrol. Don't care whether 2T gear teeth spoil, 2T tube torn, 2T rocker cable snapped, or even as simple as 2T tank level hardly going down - play it safe, immediately premix first, then bring to mototiam.

 

Too much 2T won't harm your engine - at most lots of smoke and throttle response sluggish only - but not enough 2T is a disaster

Amen to that... Better to be safe then sorry.. Poor Samuel and Andrew fell victim to this.. I'd like to add on to this..

 

If you think something wrong with your bike.. Bring it to shop asap.. Dont delay and be complacent and endanger your bike and your life..

guys , the battery breather tude for wat one ?

A piston ring is like an o-ring

but cannot be an o-ring

and an o-ring

cannot be a piston-ring

so,

a piston ring, is not an o-ring

Then wat is an o-ring?

Where is it located and wats the uses for o-ring?

 

i guess the 2 metal rings that clips onto the side of the piston are piston rings, right? so, the job of the piston rings are to expand so it will form a good seal between the top of the piston and area below the piston?

[wacko]

wah..

so many overhaul..

i might doing my top overhaul end of the year or 50000km which ever comes first..

hope its end of the year..

hari raya coming up need money..

haiz..

 

anyway...

experience a bad one last 2 days..

with my bro over at 2nd link and after the customs, i whacked my bike until 180km/hr till i felt something wobbled...

slowed down and stopped and saw my back tyres actually burst and i actually heard a pooping sound before..

rode home with a flat tyre..

best part..

its with my gal..

:cheeky:

haiz..

changed whole set for 220 at LAB..

money money money...

must be funny..

in a rich man's world...

Bro..

 

If i'm not wrong, the O ring is the metal ring that fits nicely into a groove in your engine block when you remove the cover to your block..

 

By right, you're supposed to change it every time you open up your block.. This is what i heard..

 

It is not in the cyclinder..

yes piston rings r the one that is responsible for the compression in yr engine... yr 2t also plays a part in forming the seal.... compression will start from the time yr piston ring pass yr exhuast port... original aprilias come with double rings piston to ensure good seal so that u will have better low to mid range power...

wah so many ppl servicing bike ah ... i still haven get bike yet knn.... donno still got how long . ... my bike hor is premix wor [ is it ok ? ? ? hahaha ] den hor my piston hor is [ single ring piston , ah boon tell mi ] gd ma ? i heard quite hard to find huh izzit ?

Bro,

 

Your bike premix wat? You mean 2t is usually poured into the tank is it?

 

And single ring piston? I think it's a racing piston.. Dont worry about finding parts bro.. got money sure can find one..

 

bro, wat the changes Ideal is doing to your bike before you can ride it? you better find out.. dont get screwed out of your WP shocks...

means i got no 2t box i think have to carry 2t ard when refuelling petrol den premix to gether ... haha ... ya its a racing piston ..... if they dare screwed my tat WP suspension i will gonna screwed them up .... hehee .... becos all the wiring r for racing den now he have to change back to road bike ma so wiring all have to change ...

Any idea of the top speed of the 03 models with the rs pipe?

On a '03 stockie, at least 180km/h on a relatively flat stretch of road with revs to spare........

Just make sure you always mix in the right amount.   Originally posted by spiderman@ chris meant it to be the piston ring Yup, very paiseh, piston ring I mix up with O-ring, next thing I'll be mixing up 2T tank and petrol tank Tonight, before I sleep, I will repeat to myself: "A piston ring is like an o-ring but cannot be an o-ring and an o-ring cannot be a piston-ring so, a piston ring, is not an o-ring"

Bro..

 

Why dont you get a 2t reservoir pump in? Sia la, one time forget to premix that's it.. Piston jam liao.. It's more safer..
