 Piston Step Potion - Setting Fast Becoming Shogun 125

Shoma initially raise the piston stroke or step 8 mm at Shoma's Shogun 125 of Praya, Lombok middle. But it was the power that comes out even lackluster. Finally, try to be reduced and the stroke only increased by 6 mm. The result is even tighter.


"Step piston so initially only 55.2 mm 61.2 mm,"said Suzuki was mechanically reliable manufacturer. Mechanics are good at it back Kilik mix with oversized pistons Honda Tiger 100, bore 64 mm so swollen.


The composition is proven even more fitting, though still overbore. "Actually, it was tested by increasing the stroke of 8 mm. Ketemunya be 63.2 mm. Kan should have approached the square. But even less good, "said the mechanic who ngebengkel on Jl. Kartini Raya No. 18, Depok.

Capital capacity in the range of 200 cc engine, plus the change in duration of 280 degrees back in moving the valve in 31 mm and 27 mm ex valve, rpm roar was quickly multiplied. It proved again, this bike is already competed several times.


"Even the already 20 times in succession pitted against racing on the track straight aje. The result is baseball ever lost, "said Andre, who likes to study in Bandung and Bali enliven alais wild racing.

Rextor AT 14,500 RPM


"The peak power at 11,000 rpm 41 degrees ignition served by relying on programmable Rextor. Starting at 11,500 ignition start back at 38 degrees, "added mechanical ngebul continue.


But let the machine safe, Ahon make limiter cut-off on the CDI at 14 500 rpm. "More than that fear makes motor broken. Anyway have not met the peak strength. Mending is restricted only, "said West Kalimantan was the original mechanic.


EFFECTIVE IN 800 METERS


Shoma korekannya claims is more effective in karapan 800 meter. "If 600 meters has not met its peak power," the reason. That is why, just change the gear ratio I = 13/30, 15/28 with the final gear. "Teeth standard 2,3,4. If changed, it might be different again to the ideal distance, "explained the mechanics of this straight-haired.


Enlarge handlebars PISTON PIN


Handlebars piston still use the standard Shogun. However, obstacles arise when pairs of piston Tiger. Piston pin hole in the handlebars Shogun only 14 mm pistons, piston pins Tiger is 15 mm. Automatic piston can not be installed.


Overcome them, "Enough besarin hole in the handlebars piston. Originally 14 mm to 15 mm, "light motor mechanic who often rely Suzuki though for wild racing rules like-liked.

Modif Engine Motor For Wild Racing Suzuki Satria Fu 150




Here are leaked settings make wildly racing suzuki satria owner of CMC Praya fu150 Motor Many say the harsh wild world of racing, the engine capacity should be higher or masimal. Like any other competition, racing wildly impressed just know one key "an important win!"

Well, make that want to try but what a wild sensation of racing engine power is also made daily or in a for outlets, hehehe ... do not worry, please refer to this engine modification tips ...

Engine capacity of 150cc Suzuki Satria which results from a combination of 62mm piston diameter and 48.8 mm stroke, 10.4 compression ratio has to be our specification Destroy it if you really intend to become king of the streets. The first thing to do is ... siapin money first! if there is no money which can be modif ...:)

Ok lah, I consider the money already in hand. Next we'll change the engine spec to be 61.8 mm stroke stroke results from the elevated tracks standard 6.5 mm and 65mm piston hispeed existing brands coakan valve for 4klep.


If its engine capacity is calculated to be:


V = 0.785 x 65 x 65 x 61.8 = 204.9 cc


Well, this capacity was able to make an official drag racing in the class up to 200cc 4tak duck "FFA"goOOOdddd ...!

Anyway, do not forget to stroke it takes up 6.5 mm below the aluminum block gasket 4.5 mm thick. Then the piston is made jenong with a height of just 1mm and then cut the head as much as 0.5 mm.

Talking heads talking about the valve must also ... Jump aja beat the standard valve (23-19) with valve size 25 intake and 21 exhaust. If there are difficulties in this section can directly contact me for assistance and reservations.

Then do not forget also Noken as in modif so have lift 7.8 mm with a duration of 280 intake and 276 exhaust. The next step, still seputaran head, do not forget ported in and ex into a circle, is not his standard oval ... Ported intake channel with a diameter of 28mm and 27mm exhaust.

To use only the standard valve springs because it is still strong enough koq. Problem of power distribution and per-clutch clutch alias, can be replaced with racing product .. It must be okay ..


Make sure the magnets are also exposed to 1.5 mm circular lathe let light and support the acceleration later. Here's the problem carburetor. Here is pake karbu NSR SP 28mm in diameter, it should not besar2 karbu, Ntar difficult to find opponents ... Hheheheeeehhee ...;)

Setting mainjet pilot jet 42 and 125. 1.5 swirl round. Then for the affairs of ignition, leave it on the CDI Rextor - which may be an adjustable or programmable - the setting of 15 degrees until 38 degrees at 9000 rpm. Pegged at 14 000 rpm limiter alone while for the gear ratio transmission, aka not a problem just use standard.

Lastly ... and this is the most important in this Hobby Box Shoma ... Kalo is complete run the steps above modifications suzuki satria fu150, then now is the time to earn money and I'll be racing Stay well-racing every day ... Hehehehe ...: D

SETING KOMPRESI DI 11,7 : 1


Honda BEAT Doran race is playing in setting Satria compression 11.7: 1. Through the setting, the original racer Jakarta also feels solid play in the front row 130 cc class Matik Tune Up Supermatic Indonesian Open first series Circuit Race in Kemayoran, Central Jakarta, some time ago.


"Power is on track BEAT tikungannya straight and big enough," said Doran Satria who join the team JP Racing Kawahara. In fact, through measuring machine dynotest, penetrating power in nearly 15 dk lho. That is, almost equivalent to automatic 150 cc race.


Of course, want to know the secret dong spur kitchen curtain BEAT this sunrise. Let's go together. "Not many are played. Most around the head and karbu. Then, the piston deh, "said Mariasan pocket, mechanical team based in Rice Village, Ciputat, Tangerang.


Starting from the piston first! To achieve maximum limit, of a cylinder in the 130 cc class, 54.4 mm diameter piston applications. Through Bore up method, now so 127.3 cc cylinder capacity. Self-dong

With a piston diameter that is larger than standard, suction and exhaust valves are also adjusted. For this BEAT, relying on the valve pocket Honda Sonic. But the previous Sonic valve diameter 28/24 mm re-adjusted.


"The diameter of the spigot dikecilin again. Valve in disposable 27 mm and 23 mm valves ex so, "said the man who is familiarly called Marco who was taken from the abbreviation name. Well, open-close valve affairs also made ​​repeated duration. Of course, through the alteration profile, neither the Noken as camp.

Kem, wear brand Kawahar type K-1. For the valve in, made ​​a 265 º. 28 º suction valve opens before TDC (Top Dead Point and close 57 ° after TMB (Bottom Dead Point. Medium ex valves, as well as the duration of the same application. Yup! So 265 º 57 º before TMB opens and closes 28 º before TDC.


Through change in the duration and the valve, the valve lift is now taller. For the valve in, high-force valve to 8 mm. Moderate ex valve, a little lower. That is, play in the 7.6 mm.


To maintain the stability of open-close valves, per valve sponsor Marco's Suzuki Smash. Just like a Honda Sonic, as Smash was also used per valve didobel owned Honda Grand.


Through changes around this cylinder head, piston dome is applied also has participated adjusted so as not to hit the valve. Thus, the piston dome is made to be 1.5 mm with the following coakan suction and exhaust valves.


This figure is obtained, because the cylinder head also has dipapas 0.8 mm. There is one thing that Marco applied for easier loading and block-pairs. "Gaskets replaced with an aluminum block 1 mm thick. So, if you dismantle the block, not mutually gasket, "said the man who also racers with start number 133 this.


Oh yes! Speech compression 11.7: 1, is quite low for racing racing. But, are consistent with fuel that applied at the Indonesian Super Matic Race. Namely, Pertamax Plus. So, want to try setting that is applied pocket?



SETTINGS racing carburetors

Before performing the final set-up that is in the carburetor, we should first know what's the difference who it is the same generator carburetor gak ...:) Carbu is a component of air mixing with fuel vs comparison of certain compliance and mengkabutkannya into the combustion chamber through the intake manifold and ported space first. How it works rely on a negative pressure or vacuum cylinder during the suction step. There are two types of carburetors, which rely on constant velocity of skepticism with a vacuum with menkanisme membrane, two carburetor has the advantage of each. What is certain to need a racing carburetor that can provide open and closed constantly, not a vacuum, because it adopted a racing camshaft with a large overlap automatic negative pressure piston is higher because the suction step begins far before the piston down to the suction step. Carburetor vacuum will react slowly to change this.
Now the right carburetor setting certainly already know a lot, jet pilot work is to set the idle up to a quarter throtle open, in the middle rounds that work is a bit of influence and the influence of the pilot jet and needle clip position skepticism vs. nozzle, on 3 / 4 cycle gas work only skepticism carburetor and devices, while full throtle main jet of pure duty.
The purpose of setting up the carburetor actually simple, find a mixture of air molecules against the ideal fuel to form a compound that is easy to dipantik spark plugs and have a strong potential to explode. Certain comparative figures would produce a different power and performance.
AFR 14: 1 = is ideal for mixing ratio of the standard motor in order to work normally.
AFR 13: 1 = is a comparison to performance, with a little wet but keluran to optimal power despite the economic side of the sacrificed fuel
AFR 15: 1 = emaciated ratio that will result in fuel consumption is more economical, but with the risk of excessive engine heat tends towards overheating
Therefore, for a little help, here is a table carburetor jetting motors that exist in Indonesia, nozzle size that you want to search, exchange-pilot jet main jet to find an appropriate setting, without many words okay ... enjoy research carburetor my friends! :)
