how to make a 4 stroke scooter faster how to make a 4 stroke scooter faster

The easiest way to remove the catalyst of your scooter is to replace the stock exhaust with an aftermarket model. Apparently they are built for maximum fuel efficiency and to not go faster than 30mph. Different countries have different laws. CDI The problem with those CDIs is that they are a) not documented, so youd need to reverse engineer the circuit yourself and b) they are usually one big piece of glue underneath the plastic. Your CDI is restricted and does not allow to exceed a certain rpm (VERY COMMON ON CHINESE SCOOTERS) 2. Therefore, we can say that we will gain about 2hp (depending on the model) complying with all regulations since we are not modifying the power of the engine. I mean bike is only 3yrs old, and has more than likely never bin changed, which begs the question of the longevity of belts? I am new here. Thanks mate. Heck, it would probably be easy to make a near-universal one given the network theory of economics/engineering that says that over 90% of designs are using at most 10% of components and design choices. It is obviously restricted somewhere, do you know where the restriction is and possibly how to remove it? Fast vehicles are dangerous. Anyone have a 2014 Piaggio Fly 50 4T that is derestricted? I appreciate it that you like it so much. Your manual will indicate the engine size, and the mechanic or salesperson will show you the range of muffler options.

Open up the variator system. I had to push the frakin thing up to a lesser incline the shame. Daniel, I have a new Italkit 70cc cylinder kit for a Aprilia Morini engine. Those usually come with a variator ring, and a deadpipe on the exhaust. I covered about one third of the rubber intake tube opening with tape to duplicate the restriction of the air box. Especially the main jet might need to be increased to comply with the higher engine revenues and the increased amount of fresh air supply. 4. By good I mean these can be removed easily without spending a single penny (given the right tools). A catalyst has to operate at a high temperature to perform in its intended way. All Piaggio engines are the same, therefore if the exhaust doesnt fit, its probably for a different engine Although the Stage6 have shown some horrible quality control in the past with their China goods Anyways, get in touch with the dealer and ask for a replacement. Hi Theodor, Sorry for the late reply. Examples for these are variomatic rings, exhaust dummy pipes and carburetor opening restrictions. It can be removed when disassembling the silencer. 4. I would go with 1. and buy an unrestricted CDI. This can be accomplished by either drilling holes into the air intake (located above the variator case) or by removing the intake altogether. Any insight would be appreciated as I cant seem to find a legit answer anywhere! Mhm normally this sounds like a carb adjustment issue (too big mainjet), but since you run the stock carb it should rather be too lean (too small jet). The carburator needs to be adjusted according to the amount of air it is processing. Hey mate, i have a 110cc Honda Benly. Try 1-2grams lighter ones. Examples for these parts are: electronically limited CDIs, diameter restricted inlet manifolds and increased length exhaust manifolds. The intake is attached to the scooter by two or three bolts, usually with two attached to the underside of the rear wheel well and one attached to the variator case. Variator weights are so light, that the given engine speed does not produce enough g-fore to pull the variator plates together. It runs great and has only done 2500 miles but it will only do 29mph flat out even down a hill! 2015 TuningMatters.comConcept and Development Daniel-Klose.com. Whats the jetting like? Not sure I how to increase the performance of this type of engine , been looking at all of performance heads and cylinders, carburetors, transmissions, etc. But as my name suggests, i am still relatively new to all this, and so follows the first of my quandaries, Still with the nifty (JC 50 QT-20 sudoku) http://www.mopo.fi/ajoneuvot.php?ajn=21&merkki=3, No dummy pipe fitted, unsure bout other exhaust ress as no weldin equip available, vario (? have you done any other changes besides the CDI?

Unscrew the fastening bolts located near the connect point between the exhaust pipe and the muffler. Any tips would be appreciated, cheers colin. The most common would be to increase the cubic capacity of the bike by changing the cylinder, piston and cylinder head, but, besides being a very expensive modification, we would be outside the law. Therefore, we will stick to those modifications that comply with current regulations and do not pose a problem for you, your insurer or other road users. either way ill be getin a de-restricted one. CDI Obviously pink wire had no effect, but would i be right in deducing that de-restricted CDIs have only 5 wires regardless of the pin count? If, on the other hand, we drive more on highways or interurban roads, we can install higher weights in our variator to achieve more top speed. Any idea what the top speed would be with a un-restricted CDI? UNBURNT so, of course there is no loss of energy. Tho the stock engine wont have the power to rev higher by default. 2. Belt Belt life depends more on the usage raher than the age. Seems it is scooter with max speed 25km/h. The belt is too narrow.

When buying an already restricted scooter make sure to receive all the parts needed to derestrict the scooter again. Im an under age scooter rider from India. In some states, 50cc scooters that can travel over 30mph must be registered as larger class motorcycles. The only thing that happens is that it allows to rev the engine higher.

Thanks for the help have ordered some new sprockets thanks shaun, Hi, I just got my Vespa Primavera 50 2T derestricted in certified Vespa garage, but on my way home I noticed that acceleration isnt what it used to be. These restrictions are usually provided by third parties which means it is not a restriction applied by the manufacturer of the scooter but a kit bought from a company that specialises in restricting scooters to comply with local drivers license laws. Derestricting a scooter makes it faster and therefore more dangerous to ride. Best Overall. The kind that had epoxy not to keep moisture out, but human eyes.

Here's an easy way to understand how an engine creates power. . Certainly too heavy rollers. It depends on what is available in your country, but I recommend the Naraku Unrestricted CDI available from Racing-Planet (they have shops in Germany and US). i believe the vario roller weights need increasing is this correct and to what sort of weight ? Following your guide I have now removed the variator ring, and looked for the exhaust restriction on the Leo Vince Touring, but it was not present. Is the rev increasing then? The new muffler will enable your scooter's engine to expel exhaust faster and cleaner, allowing more air to enter the engine during fuel combustion. So you took the clutch a part and now it only goes half speed? Ive asked the shops about the CDIs, and they are saying it doesnt work with the Bullet RS.

However, this will not make your scooter faster, but only allow it to rev higher. At least YOU have an understanding of the operation & function of the parts you talk about, and describe them in a manner that is easy to comprehend. This is often contradictory to the speed limit requirement as fast accelerating scooters also reach high top speeds. My question is my bike seems like it loses power or acceleration. There are some bigger engine scooters with restrictions but it is very untypical for them to be restricted. Hey Daniel, Do you have any ideas/tips on how to derestrict a 2016 Lance Cabo 50?

However, sometimes the manifold is even to small for the stock carburator. Hope these 50cc scooter upgrades help you make your scooter faster. Will a bigger carb make my bike faster? The piston goes up, compressing the air/fuel mixture. Buying an unrestricted CDI overcomes this limitation. In most cases derestricting the scooter not only improves the performance of the engine it also allows it to perform better, longer. Anyway the engine still bogs down after the initial acceleration, in fact it has the opposite of the very sharp 2 stroke acceleration I was used to with my previous 96 Piaggio. Thank you for the information combined in such a nice article! hi david i live in pakistan and have a yamaha junoon yd 100 and its cdi has gone faulty.the original is 1.too expensive 2.not availble any where near to me 3.its quality is not good as compared to the original one that came with the bike so it will probs go faulty again.what im thinking is of installing cg 125s cdi and coil with my own bikenow what i wanted to know is what are the disadvantages of having too much spark in the spark plug.i mean im installing a heavy cdi in place of original one, Hi I have this 50cc Pocket bike Im a person that loves to go fast.

Would really like to see it. After doing the above jobs i still noticed no further top end addition, although i did solve the bogging issue through the acceleration range. Id like some help on how to get the moped to reach higher speeds. You will find a lot of information on those on my site :), I have found that on Tao Tao Scooters and Roketa, as well as most other Chinese scooters too; that removing the black plastic plate between the cylinder head and intake manifold greatly increases the power of the scooter, that combined with removing the air box, blocking off the emissions system with a vacuum cap on the intake manifold, replacing the main jet with a #95 jet and installing a UNI Filter is a cheap and extremely effective way of getting tons more power out of your engine. These can be assumed safe to remove without affecting the life time of an engine. Ive got a 1984 honda nh125 / 1999 af28 dio you will have to see it to get what I mean but the problem is for me that it is only getting up to 1/2 the speed that the specks say it can reach and thats after having a few aftermarket parts can you help please. they all look the same!

Altogether I recommend to get another (newer) scooter model as tuning parts for these old Hondas are very expensive if you can find any at all :-/. I know that writing articles is boring and time consuming. Usually too big when it bogs but if your airfilter is too big (eg racing airfilter) this also happens when the jet is too small.
