Thanks Aaron and Draka for your feedback..

Looks like it's going to be really worth it IF i ever get it.

Draka, who tuned your bike for you? What's your settings?

Aaron, what's your settings?

Dear Friends,

I'm looking to offload a 34mm carb, for the post 06 model RS125. Purchased Oct 09 if

I'm not mistaken. Looks very new. Was bought when exchange rate was 2.35 to the

damn british pound. You do the maths. Check out the price at PJME.

Asking for $250. 34mm carb manifold(2ndhand)= $30

(can be used for pre 06 rs 125 as well)

You'll need both.

PM me or call/sms at 93352445 if interested.

You'll be saving alot instead of ordering a new one online. And you need to factor in

GST and shipping. It aint that cheap.

Cheers

Decided against the BBK. The BBK will give more low end power but overall power won't go up much. What I want is power at higher RPMs. Using a cone, 34mm carb and jetting it properly (135 or 145 maybe) will give more power. Oh, and the vForce3 reed block too. I'll eventually put in a programmable CDI too. That won't be any time soon though since I'm keeping the bike till the COE expires.
Just a side note: The BBK doesn't rev as high as the stock either.

It's fine if I can't get it ported here. But do the racing teams like HKL do it?

RSV4 or ZX14 for class 2?

Oh man, kindred spirit!

Finally here's someone who bothers to do their own homework before opening his gap! First time this has happened here in this forum!

Yes, the big bore kit gives better torque at low revs. Yes, it is not designed to have the same rev ceiling as the Rotax original cylinder. Yes, it is only good for low speed pick-up, it suffers at high revs, and keeping the revs high will kill the engine.

To use the programmable CDI, you'll need a ported block to maximise the power. If you wish to keep your cylinder stock, the stock CDI is good enough.

There's no one in SG who can port our blocks sui sui. Trust me, after spending more than $20,000 trying out porting from difference mechs, I must say, no one knows what they're doing. Stock is best.

If you really must have a race ported cylinder, Edwin can get one for you. The one I'm currently using is better than the big bore kit. Honest to god.

Still stays legal because there is no change to the displacement. The fresh charge and exhaust just has better flow through the ports.

Anyone interested in Brand New Stock Aprilia blocks?? Most likely ordering ard late June period.. starts saving up for those who are interested.. Price ard $700-$750..

For Fairing wise, anyone interested in Full CF fairing by Sebimoto? Price ard sgd$1800 including shipping etc.. Lead time ard 4month upon order as these are made to order..

Full CF? Yes please. I only need front cowl, left and right side fairing, and maybe the tail.

Hey, can any Aprilia RS125 riders write up a tentative review of the bike?

Similar to this: http://www.singaporebikes.com/forums/showpost.php?p=6315184&postcount=205

Appreciate it loads.

And how do I "auto-subscribe" to a thread? The threads that I posted in never appear in my User CP.

The revs are what that is actually needed. Because of the small engine capacity it has to be able to rev high to draw more power out of the engine. The stock has enough low range torque in my opinion. What I'm looking for is power higher up in the rev band, say 6k upwards, for easy overtaking etc.

$20K How much would it cost to get Edwin to bring in a ported block and piston? Not trying to turn it into a track bike, just a more powerful one. Don't want to spend a ton of money on this. The CDI will be the last thing I do to it because I'd need to get the bike dyno-ed and tuned properly. That won't be happening any time soon. Still have to save for a car.

I await to see how long u to take to do up your bike. Maybe when it's done, we can have a demo?

I think, before one decides to set up their bike, one needs to have a clear picture of what one wants. So do you want your bike to be set up for street riding? Track riding? It's very difficult to find a balance for both. From the looks of it, if you just want power, get a bigger cc bike. There's not much to be squeezed out of the 125cc. I think quite afew guys here have pushed it to the limit. Honestly, my desire would be to have a ride that's smooth and accelerates without any jerkiness. I'd rather give up some top end power to have a really smooth, fast ride.

You seem to talk about high revs, how often are you going to be using them? Especially on the road? Unless of course, you are riding on track, tat's a different matter. Even so, I dont rev beyond 11K RPM on track, but that's me. The others here might have different riding styles.

Personally, for street riding, I'd go with the Big bore kit. It's gives u the torque to manage road riding, and the pull is really good if you get your bike tuned up.

We should meet up in person to discuss. You seem to have alot of ideas.

Hi,

Forgive me for saying this, but i think it's a very stupid thing to do. Unless of course, you have money to burn.

IF you're changing your endcan to a supposedly better one, in terms of performance, it's really dumb. I cant think of any endcan tat increases power for the rs125. I believe(correct me if I am wrong), it's the belly of the exhaust system that matters.

IF you're changing purely for cosmetic reasons, well, that's another stupid thing to do. Unless of course, you're willing to burn your daddy's money.

And the idiot who buys your endcan, will be just inviting the TP/ROV to ask him to make a donation. If I'm not wrong, it's the full system tat's deemed street legal, modifying/removing any part of it makes it ILLEGAL. So you with the belly, will be also making a donation if caught.

Just my 2 cents.

ya , true ...the front pipe is the 1 doing the job and separating it will only attract tp/ROV but not optimised the performance .

High revs is what the bike is made for. The Polini big bore kit was originally made for the SX125, which would give the scrambler more low end torque, instead of having to wait till the revs were high enough to pull. By then, it'd be too late for you to clear the mound, jump, or hill. Some smartass figured to fit it onto the RS125, and next thing you know, it spawned a whole new generation of dreamers wanting low end torque on the RS125.

I ride with my revs within the 8,000-12,000rpm powerband most of the time on the move. Only when moving off from traffic lights is my bike chugging in unfamiliar territory below the 8-12k rpm range.

Our bikes don't have flat spots, IF YOU KNOW HOW TO RIDE THEM RIGHT.

I agree, stock has enough low end torque. Enough for me to move off from a stationary position. After that, my bike runs at full power with my powervalve open all the time. No flat spots, no power lag, with enough pull for overtaking. Want proof?

All in a day's ride. Sorry guys, video's not very exciting cos the rider had to ride slower and more safely than normal since he doesn't have any demerit points left to be deducted.

I dun see why one bike can't be street and track ready? You dun need to put tons of upgrade parts and extreme tuning to make it track ready. An engine with good setting should be good response, reasonable power cruve and all these based on good fuel efficency with reasonanle A/F range. The only things I can see the different between on street and on track is the spark plug and little bit more 2T %. BBK or not is not an issue, even OHV engine ppl make them race machine. There will be a solution to settle everything, just need to find the right guy and have good feeling about what's going on under your ass when you riding her and capable to translate to your mech. This feed back will help you shape up your bike to suit your riding pattern or the bike will shape you up to be capable to use the full potential of the bike.

It should take pretty long. I've only my weekends to get anything done on the bike and I've usually got stuff on during the weekends. Maybe 2 to 3 weeks just to get a single thing done. If I've to do OT for work (which I suspect I will have plenty of) then it'll take far longer. First step will be to overhaul the engine, it's just about due for it. Wiseco piston maybe. Then I'll have to source around and find the parts I want.

Being able to accelerate smoothly depends on the CDI (because of the power curve) and throttle response. A jap bike doesn't really do that very well in my opinion.

That's because I redline the bike everyday when I ride. When cruising around at 100KMPH or so it's already at 7K RPM. At 7K it's fine, but below 7K the it becomes slow at picking up speed. And on the express way you rarely drop below 6K RPM. That's why I want power from 6K upwards. I'm on the express ways most of the time (before and after peak hours) and barely ride around town or any congested area. I just think it's troublesome to drop gears to get into the power band to accelerate that's why I'm looking for more power. Yes I know it's a stupid reason to mod the bike, but why not? It's going to be my weekday transport for the next 5 years. Not going to change to a 4 stroker for fuel efficiency because none of them are as nice to ride as the RS. Don't want a bigger bike either, when I get my class 2 bike it will only be for weekend riding anyway.

I've already planned out what I want on the bike. All I've to do is find the parts and get it done. Haven't decided on an exhaust yet though. Don't want an Arrow or Gianelli one, too common. Might get the Jolly Moto Corsa one though. Never seen one of those around here. Have to sort out my clutch still though, the biting point is very chui already.

I'm sure the BBK can be tuned to give power higher up too by porting the cylinder and giving it a longer stroke. But that kind of defeats its purpose.

8K most of the time, you always speeding ar? Why don't you rewire the solenoid so that it goes to a button/switch instead of the RAVE controller? Then when you press it the valve opens and it's like having NOS on the bike. You will lose midrange power with the valve open though.

That looks like very cautious riding

1.1K for the polini including installation at FM? That's a really good price. Mah charges 1.4K if I'm not wrong. And they dont really do a good job. They're hopeless at settings IMO.

Regarding the conversion from 05 to 06, does your frame have the same mounting points to accomadate the fairings too? Better check.

Jolly Moto has been around for a few years now. I've seen a few and have gone head to head with some. They're good.

The Arrow/Gianelli system, however, is more of an all-rounder, like the Swiss army knife of exhausts. Its got a good compromise of low end torque to high end power, so generally your ride is pretty smooth and top end is not bad.

I'm sure the BBK can be tuned to give power higher up too by porting the cylinder and giving it a longer stroke. But that kind of defeats its purpose.

The BBK's rev ceiling limitation is not in the porting, but in the laws of physics. BBKs changes the size of your bore, but not the stroke. You can generate more power at lower revs due to the larger displacement, but with a larger bore you'll need a shorter stroke.

At high revs, the larger piston has to travel the same length as a 125's, so does the conrod, and this places more stress on parts originally designed for the stock piston and cylinder. BBK means larger piston, which means more mass moving at the same stroke as the 125, which usually translates to more vibrations that BBK riders complain about.

This means that BBKs are practical for riders who never intend to ride to the bike's limit, nor wish to push the revs above 9,000rpm thereabouts. In the last 8 years I've gotten to know many BBK riders. Most have had their engines die on them within 3,000km of installing the BBK, because they insist on keeping the revs high.

The BBK is not incapable of reaching maximum rpm. But just note that if you intend to keep the revs up there for extended periods of riding, be prepared for premature conrod breakages, piston seizures, and bearing deterioration. FACT.

Can't say you haven't been warned...

The valve isn't really a boost. It ensures that we have optimal pressure by varying the size of the exhaust port at different rpm. 2-stroke engines suffer from power loss outside of its powerband when the pressure conditions are not right. The powervalve compensates for this.

Having the valve opening early will only cause a drop in power.

Yes, that's very cautious riding. Just to illustrate my point on having enough pull for acceleration and overtaking, like at 0:30, 2:28, 3:38, to name a few...

The rider used to ride a lot faster, max speed at max revs from Point A to Point B, rain or shine. No exceptions.

The rave unit can be easily altered to open at 6.5k ,7.5k compared to stock stock 8.25k rpm. How to acheived a balance system for max power output if valve is to be open at 6.5k w/o building up enough back pressure for sufficient recharge for higher rev , is the interesting question?

Infinite combinations of parts are possible but are only limited by our knowlegde , $$$ and access to parts for different setup

There is more than BBK, exhuast system,carb , Vforce3, HPI to achieve good balanced system..

Who would need so much power / torque on the low end?

If you're into poppping wheelies at yishun dam or infront of the tp bikes camping under the bridges on a hot sunny day then maybe lah..

Maybe next time I would wanna learn how to pop a wheelie..

Then slap on a bbk, p-plate and pop one right at orchard road
