I've also never understood what performance gain sealing off the exhaust valve port gives - as far as I can reason, it can only cut down on maintenance.   Originally posted by lightbolt75+--> QUOTE (lightbolt75) Actually my riding style is pretty much the same as urs.[/b] That's great! This means you and I can have a fairly accurate comparison of how modifications can worsen fuel consumption. Is your bike completely stock?   Originally posted by lightbolt75 Lawrence should be around at AMK also? Maybe can ask him to come along? Actually I have no idea what services does his shop provide besides stickers I'll leave this for Lawrence to answer, but suffice to say that his shop provides plenty of stuff, not the least of which is the full Unil-Opal product line - 2T, 4T, gear oil, coolant, fork oil, chain lube, cleaning solvents, etc.

Guys, I think u are having a small misconception on the purpose of the powervalve and its maintenance. Riding with and open valve all the way is not really gona help much.

Paul, owner and mech of workshop Race Incorp, and former Aprilia mechanic at Ideal Motor Sport, claims that RS125 power valves have a self-cleaning feature whereby they vibrate rapidly when in open position, discarding accumulated deposits and keeping the valve clean.

 

I don't know how true this is since I don't have any Aprilia workshop or technical manuals though I plan to get my hands on some. However, my experience has been that my valve jams when I don't open it often enough, and stays fine when I open it regularly, even if I don't clean it for 2 months.

 

---------

 

On the subject of spending money on modifying 125cc Aprilias: my perspective is that I intend to keep my RS125 for at least several years, even after I've gotten my class 2A and class 2 licences, simply because restricting my engine size restricts my running costs to some extent. 1 spark plug vs 4 spark plugs; road tax; gear/engine oil; it all adds up - I've done the numbers. Modifying is also fun, and it's a way to have a bike that performs beyond what people may expect.

 

Keeping a 125cc 2-stroke is also a great way to race on the track at a level that's safe and fun. I may never ever get anywhere near good enough on a 600, but with a 125, got chance at least.

125 is like so modifiable (if there's a word like this) i can do so much stuffs on my

own...

 

thou 250 is faster and better.. but there's always faster and better bikes ard...

how are we gonna keep up with it??

Hi guys,

 

I'm very depressed.. I've gotta certain no. of problems that i need your opinon and help..

 

1)White smoke - Till this day, i do not know why is my bike still belching white smoke.. My bike has been ridden by my bro.. and he has whacked it hard so it cant be carbon in the exhaust.. He even brought it to the shop and had them drain out the old 2T and put in new one.. yet, the bike belching out white smoke.. the min i start the bike, smoke comes out.. i ride abit and come to a stop, smoke comes out.. only at higher gears, there's little smoke, but could be cause i going faster... Any ideas?

 

2)My speedo and trip not working.. i discover the speedo cable hanging out this morning.. Any idea where i can get it done up and how much? And are the speedo and trip both associated with the same cable or different? i was told by someone who got his speedo fixed that it cost 120 to replace that teeny gear part... how?

 

3) Spots of black oil found below my bike.. leaking engine oil.. God knows fm where? Wat are the reprecussions of this and how much to get it fixed??

 

 

I cant take it sia.. before getting my license oredi so much problem.. If i din love Aprilia so much, i'd hang myself... :cry:

 

please help!!

i got a service manual[/b] Heheh, yah, I remember you mentioned that you had the soft copy of one. A torrent would be great, if it's not too inconvenient, otherwise please don't waste a CD - I'll just pass you a flash drive the next time we meet.   Originally posted by eyz+--> QUOTE (eyz) sealing the exhaust valve port is needed when ya remove the valve[/b] What I meant was I don't think there are any high-end performance gains to be had from removing the valve and sealing the port, versus keeping the stock valve assembly. All you would gain would be not having to worry about your valve jamming. For low-end performance, of course, it would be a definite downgrade.   Originally posted by eyz yah.. i can't figure wat's that sound... it seems so werid... he said it's the teflon balancer You're talking about the sound that's like mice running around inside his engine block, right? That's definitely weird. But what I find even weirder is the sound of his engine when he throttles hard - it's not constant, but instead quivers/vibrates like an Italian opera singer, hurhur. Now that's the weirdest sound I've ever heard coming out of an Aprilia.

Viknesh, when you say your bike's belching white smoke, do you mean there's more smoke than our bikes? 2-strokers across the board emit more smoke than 4-strokers. We all emit plenty of white smoke. What brand of 2T are you using? The higher end ones are supposedly formulated to reduce the amount of smoke emitted.

 

About your speedo: Have you tried sticking the cable back in? Instead of replacing the stock analogue speedo, you might want to consider getting a cheaper, yet more effective digital speedo like what Law and I have. Check out either of our bikes when you have the chance.

 

Leaking oil: Look for telltale streaks on your engine to diagnose where it's coming from. It could be many things. Where under the bike do the spots appear, exactly?

 

Since you bought your bike, has it ever been looked at by a mechanic? That's not just a good idea, it's a requirement. I know you can't ride it there, but what's the status of your insurance? Can anyone else ride it to a mechanic for you?

 

Keep it together brother, maintain, there's no need to panic at this stage yet.

1) Check your exhaust/end can tip to see if you have black oil (unburned 2T). Coz my bike last time was tuned such that a lot of 2T flowing in. But coz never rev hard, so a lot of unburned 2T. Having said, too much 2T also means more smoke.

 

2)My speedo cable drop before too. See if you can screw it back. Every now and then, i still need to tighten it up. Think Axxis has this speedo cable problem dropping out on his CBR too.

Chris,

 

It's definitely much more smoke than you guys emit.. I've seen your bikes.. and my bike is like blowing out the smoke like there's no tomorrow... All i know is tat my 2T is nothing special.. cost 7 bucks.. not sure wat brand.. must ask my bro..

 

Abt the speedo, i'm a completely noob when it comes to fixing the bike, so i'll be getting my bro(as usual) to take a look at it.. In the meantime, i shall try to fix it in like wat u suggested.. Worse come to worse, get a speedo like yours if it can be fixed and has to be replaced.. How much was yours?

 

The oil appears mainly directly below the centre of the bike, and another sopt slightly towards the rear of the bike.. b4 the rear tyre, below the seat like that.. I'll give more details tmr when there's light for me to see exactly where on the engine..

 

My main worry is the smoke bro.. Just cant get what causes it.. From startng the bike, to coming to a stop.. it jus gives on blowing.. when i'm neutral, i throttle abit, more smoke comes out.. I'm quite sure it aint carbon in the pipe.. My only guess is that the 2T might be leaking??

 

My bike jus returned fm the shop last week too.. My bro brought it there to get the 2T drained as i mentioned and topped off with new one.. The shop fella said there should be no more white smoke... But... haiz...

 

Thanks for your kind words bro..

I can screw back the speedo cable by hand? Will try tmr!!

 

Think you might have a point of too much 2t flowing in... That's why i think my 2t might be leaking... could be the reason oil on the floor and so much white smoke..

$7 bucks? sounds like the culprit to me.

hiya ur speedo cable i told u can screw back liao ma.. oni tt u muz make sure ur speedo gears are still there if not no use no whr to screw into also.. haha

 

ur 2t.. $7 -_-" fyi im sure most of us here are actually spending quite alot on good 2t (fully syn 1s) if im nt wrong.. coz we dun 1 our babies to suffer n in the end fail on us =(

Others might disagree, but I say your $7 2T sounds like a potential problem. Most of us use at least mid-range 2T (typically above $10) because, hey, that layer of 2T oil is all that's protecting your engine from wear. You don't need to use top-of-the-line stuff (though I do) for adequate protection. For starters, try a bottle of Unil-Opal "Racing" 2T from Lawrence's shop, which should almost certainly be well below $20, as see if that helps at all. It'll certainly be good for your engine.

 

I think my VDO digital speedo was something like $60, can't really remember, ask Law.

 

gonggong made a good point, your bike could be set to use a hell of a lot of 2T. Get your bro or another mech to take a close look at your settings.

nitey guys...

 

-peace out-

[xxes123]

the teflon balancer is the gear(ENGINE) baLANCER Tat i have been teeling u guys,

my mad bro in law customised his gear balancer into cast iron($300 a pair) 1-2mth a new pair.. normal balancer he 1-2 weeks change once.. :giddy:

 

the teflon balancer is not the cause of weird sound , its the 250 arrow stomach...

[xxes123]

the leaking oil is most prob gear oil, the seal cost ard $8-10+ , small problem only, my one also leak and its been 5000km since my last oil change..... tommorrow i going FM settle liao... small problem only , no need panic... :smile:

 

too much smoke is probably cheap 2T plus open tooooo big, wat ur 2t comsumption...

 

worse case for white smoke is coolant go into engine.. tat one:goodluck: :goodluck:
