ok just want to know.

But, concerning police radar and technical control speed rollers, I found and tested sucessful solution :-)

A friend of mine programed and made me adjustable cdi of oem kymco unit that costed me 30 eur.
Tested it and it works :-)

Now I have 4 options/levels of rpm's
5000 rpm max,6500, 8500 and no rev limiter
So, whatever modifications you do(comletely de-restricted, big bore, racing variator, upgraded carb),
cdi could be adjusted not to make scooter go faster than 45-50 km/h
And it's operated by front brake lever clicking scheme !

[streido]

Wow woodcutter thats very cool. Sounds like something from James Bond  . Good idea.

[blue]

true the cops around here are geting smart afew friends of mine was told to get a plate and a cycle license if its over a 50 cc.

[woodcutter]

I guess it's not so James Bond 'cause it looks simple to do :-)  Personally, I don't understand all that's done.
My friend have a certain level of knowledge. he is electric engineer.
He stripped oem cdi and by-passed some contacts inside with a small, programable, 12 v current restrictor.
Than connected restrictor to front brake contact.Of course, I needed to remove front mask with head light and front handlebar cover. Every front brake click cheme(current shock scheme) is pre-set in restrictor, and every scheme activates one of four possible current/rpm restrictions.

Than, cdi and restrictor are wraped up togeter with duct tape, and I managed to pack it up where cdi should be.
Doesn't look neat but it works :-)

Sorry for off topic but I felt I should share this with you guys!

<keep off topic> In the Netherlands most cops don't have a clue, but some cops are very smart when it comes to finding or suspecting limiters.

If your scoot sounds a little like it could have more power than stock or when it sounds like it doesn't rev up all the way it should do (sometimes they use rev counters when they put your bike on the dyno), they will let you choose between pointing out where you hid the limiter and how it works, or they will take the bike with them and pull the whole thing apart. And yes, they do know how a scoot works and what kind of limiters there are, even the brake lever schemes are well known... And on top of all the fun they will not only fine you for tuning your scoot but also for using an illegal device to try and hide it.

I've settled on keeping the original CDI rev limiter (which is legal because it can't be adjusted) (and it also lets the engine rev up like expected) and I chose a variator setting (with washers/shims) for such a speed that I will get fined but they will not seize my scoot when they put it on a dyno.

It will cost me some euros some day, but the damage will be limited and I don't have to suffer from rev-limiter-paranoia..

What is top speed of your scooter?
And what is penalty if you are going faster than it is allowed?
I saw there is 25 km/h and 45 km/h restriction in benelux I think

Same here, police is authorised to take scooter to expertise if officer suspects it's modified.
But, generally they measure combustion chamber and if it is more than 49 cc, licence plate is taken off and a fine must be payed. This is done if scooter topping way over 60 kmh on speed rollers. 
So, I'm not going to touch cylinder. Up to 60 kmh is tolerated because police here knows how much woulnerable scooter drivers are and how much this 10-15 km/h means to us in everyday urban driving. Car drivers often have low level of tolerance.

Anyway, all I did on mine was full de-restriction, cdi variable rpm's mod. and I tryed malossi multivar with 5.7g rollers.Everything else is stock.
Hitting well over 60(real) kmh now(a few kms less with windshield on) but 5000 +-500 rpm restriction is keeping me in range of 45 km/h.

Crossed my mind to bring back orig. cdi and variator set up(although I'm very pleased with expensive mallossi)
and install 5.5 g rollers .
Thats under 60, so, less for mods. more left for drugs :-)

Since not all dynos are created equal and there is a large margin of error, it's not an exact science here...

My personal limit is the result of some educated guesswork based upon experiences of others with certain setups and results.

With a dyno result between 50 and 65km/h (legal corrections for error margin included) the fine will be affordable for the average adult, at or above 75km/h things start looking grim...

Luckily they don't take the time to measure displacement and they will only seize your bike after a few warnings (if it's not ridiculously fast that is...)

[woodcutter]

Fair enough
That means as long as you keep your 50 cc scooter in a range of 50 - 65 km/h, you get a few warnings before seizure and a affordable fine.
I guess it's acceptable compared to 'A' licence cost :-)

Here, displacement measure expertise is done mainly on a very fast 2 strokes doing 80+(yamaha aerox, gilera runner, piaggio, etc) with resonant/open exhausts, 70 cc kits...
Even police now makes difference between 2 and 4 stroke 50 cc's.

Dam fellas.... socialism sux
$10 here for a lisence, A 1 pg test

[hungryrussian]

the cops around here have no clue how a scooter works nor do they even bother pulling you over for speeding unless they're having a bad day i've been pulled and told to slow it down before but never gotten a ticket scoots aren't real popular in my area though since the speed limit is 55 on 2 lane roads just about everywhere here

[woodcutter]

thebatman, what kind of licence is 10 $ there? moped or full motocycle?

mono, is this conductive glue you mentioned before in form of silicone that could be removed from cut
or in form of glue that hardens when dry?

The glue I used is meant for fixing printed circuit boards and that kind of stuff, it's a thin kind of glue with silver powder in it. It can be applied with a small brush and when dry it forms a thin and hard layer with quite good conductivity. I did three layers in the hole that I milled in the CDI, and it measures well below 1 Ohm now from side to side, which is as good as a straight wire for this kind of electronics.

Check your local electronics shop. In the Netherlands the brand is called "Bison Elektro" - as far as I know that's only available over here, but there should be more suppliers of this kind of stuff around the world.

Scoots dont need anything at all..............here in N.C........yet.
I think they have raised the price on the license here but they are good for like 8-10 yrs, but yeah drivers license, M.E.

[woodcutter]

Managed to put a small double bended piece of copper plate to re-connect restrictor in cdi
and sealed with silicone. It works but it's not funny to drive with restriction again :-)

Anyway, have someone tryed 732 x 18 x 8  30' belt?

Few days ago I installed Gates with these dimensions over Malossi Multivar and 5.7 g Malossi roller weights
and it worked great after initial belt wear in.
Main torque and flying clutch spring/s are stock and works very good with this set up.

Even more constant acceleration and 5% more speed and belt is not touching elec. starter gear.

 

[woodcutter]

Actually, it's 748 in lenght after I tape measured it.
I bought it as a 732 and there were no written dimensions on the belt itself.
Original belt was too short and stock variator had some 0.5 - 0.6 cm left to push the belt up to outer edge.
Even more on the outer fixed plate.

It's ok for stock var., doesn't touch the starter bendix.
Now, belt it traveling just to the edge as it should.
But malossi multivar is a few mm more in diameter(just like outer fixed plate pulley) and I guess I'll need even longer belt!!
Something like 752 or maybe even longer.

Someone had the same or simmilar issue?
