Should we look for Aluminum or some type of steel?

You want hi tensile steel, but an explanation is in order, a harder axle will take a lot more abuse without bending but if you over abuse it, it will snap instead of just bending

I'm on my fourth axle. Thankfully they're only about 10$ which is a lot for a bolt but cheap compared to a lot of other parts.

Does a CDI unit really improves my performance and top speed? 8-)Well it depends a lot on which CDI you install, and if it compatible with your ruckus, older ruckus had one capacitor in the ECM, and they use that to fire the ignition coil, at around 8000 rpms, it start cutting the ignition preventing the engine from going faster than 8k, so most Japanese CDI boxes replace this capacitor with one of its own, and bypass the circuit that limit rpms, my only concern would be that maybe the quality of this capacitors is not as good as the factory one, but it will allow you more rpms, however the Europeans has gone one step forward by using another capacitor in their CDI boxes but keeping the factory one still operating, this is ideal as two capacitors create not one but two sparks, burning fuel more efficient, therefore producing more torque, and this extra capacitor will keep the engine firing past its rev limiter, so in conclusion a first generation CDI will eliminate your rev limit but provably will not give you more power, a second generation CDI will give you more torque ergo more power, now the Honda engineers have a two capacitor ECM in the 2006 ruckus and probably in the 2006 metro, and that is why they have more power, now we need Daytona and Kitaco to copy Polini so we can have a second generation CDI for our carb ruckus

So is the extra torque gained by having two sparks really significant or are we talking like a 0.2% increase? Is there actually 2 sparks or is it just a double shot of the voltage producing one super spark? Also, can you achieve something similar to the 2 capacitor system by buying a awesome spark plug plus a H.O. ignition coil and the BSS spark plug exciter? Lastly, what effect does this have on our electrical system? I think we only produce something like 180 watts at 6000rpm (if I recall correctly) so are we using up significantly more of this with 2 capacitors?

about two question ago i answered about capacitor discharge ignition, they produce a much more intense spark but it only last a fraction of what an inductive spark will last, however by adding one more capacitor you can produce "another" spark and still last less than an inductive one, gas is suposse to burn from the spark outward, adding another spark will burnt any remaning gas and keep the control burn inside the cylinder going strong, pushing the piston downward for a longer period of time, giving you more torque, i guess about 5-10% more, at the 5-7000 rpm range (were we need it the most), so the answer is they are two diferent sparks not one superspark, back in the good old days the use to have two spark plugs for cylinder to get a similar result, we already have a HO ignition coil, the exciter just prevent the spark from jumping to ground and get weaker, the extra capacitor might use up an extra watt, so it should not mess up with the charging system

Interesting stuff...I love this kind of talk. Your detailed response has spurred a few more questions within me: 1) About the whole 'superspark' vs. dualspark situation. Does the Polini CDI intentionally set one a millisecond later or how do they not both happen at the same instant? Or perhaps they do but they just never end up being exactly right on. Also, I thought the ignition coil is what stores up the power to create the spark so how can you get a dual spark without 2 coils? 2) About an aftermarket ignition coil. I was thinking about buying this coil in the following link because...well...I just like to have everything. It's made by KRS and it's the same one PomeRuck bought back in the day. Pome said he thought there was a small improvement but that's hard to tell off the seat of your pants. Anyways, is this coil a complete waste of my money or will it do atleast a bit of good? This coil comes in a couple versions but the 2nd picture listed shows the Honda version I believe. cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=45995712893) About the BSS Spark Plug Exciter, so that prevents the spark from jumping and getting weaker but is this an issue or will it be one later for whatever reason? I'll get one if it actually helps or if it's a good thing to have but I don't want to get 0 benefit for my money. 4) Is there any chance we could use the Polini CDI and just not use the F.I. part of it? Actually, now that I think about it you said the 2006 Ruckus has 2 capacitors in the ECM so that would be pointless. Or would it make it 3 sparks for another 2% gain?? Are you sure the 06 has 2 capacitors or guessing because the 06 hasn't been pleased so far? Perhaps someone will come out with a 2006- ? Ruckus CDI that simply eliminates the redline but does nothing else. Judging by the Polini HP graph the peak hp lies higher than 8K so I'd like to have mine revving to at least 9K.

1.-DD you need to go back and read my post about ignitions, the coil is a transformer, it boost the batt voltage into the 20ks volt needed to jump a spark in the sparkplug, the capacitor boost the primary circuit in the coil, and then the secondary just shoot the voltage to 40k, so as soon as that field collapsesd the coil is ready to create another

the coils so i have heard from japanese zoomer websites are not much of a difference, what you get from it is the "placebo" effect thinking that your ruckus is performing better. I wanted to get wires too but i bet it might even weaken your spark strength coz you have to cut and re attach the wirings like the NGK one sold at Jiang Wayne

I went back and read your ignition post. From the sounds of it we've got the good system but it's too bad the 03-05 Ruckus's don't have the dual spark. Are you sure the 06's have it?

NO i am not sure, because it is not posted in any site, but judging from the information we have the only reasonable explanation is a multiple discharge ignition in the '06, that will explain the better pick-up and the nose dive when they install an aftetrmarket CDI

8-)Back to your original questions the aftermarket coil is not better than the stock, just looks nicer. The exciter have a resistor in the spark plug connector so it makes the spark jump this resistor and create a shorter more intense spark at the spark plug, it makes an inductive ignition perform somewhat similar to a capacitor discharge one, but we already have a capacitor discharge ignition, so i see no need for one What we need is for some one to make a CDI that acts like the polini and have a real rev limiter (maybe MSD )

So you're saying we need a flux capacitor in other words.

Um, so can we just buy a stock '06 CDI and install it on our 05s and earliers for the same dual spark?

Unlikely...if it was only that simple, life would be grand.

The ECMs are really expensive even if it would work...

Question: What should I use to seal the 2 halves of my case back together. I've got some liquid 'gasket maker' on hand that you apply a thin coat to and let it turn gummy when it's used on gaskets. I was gonna try that but is there a better substance?

8-)What you need is something that comes in tubes, like toothpaste use to came in, the one we use is the silicone sealer from Nissan, but permatex makes a great one called ultra grey (or something similar), if i remember right is 599, but regarless, use a silicone sealer from an autopart, there is a lot of them but stick to a known brand ;D

Um, so can we just buy a stock '06 CDI and install it on our 05s and earliers for the same dual spark? The CDI in a stock ruckus is the ECM (computer or Electronic Control Module), i just hope some manufacturer warms to the idea of suplementing the stock capacitor with one inside the CDI instead of replacing the stock one
