This time we expose the craft of motorcycle bearing the tuning fork probe, so ... for vehicle owners vega / Crypton / jupiter z who want to have a motorcycle fast without bore up, this is the tale! Woi sing buri ojo turu didongengi nek, i even drool Kae piyeee ... Modify machine yamaha 200 cc bore up so fast ... = normal wear cannibal blocks supra125 temlar roller head + piston bore up tiger, tight = fair, exorbitant capital modifications are sent to Thailand, fast, fair ... minimal capital sent to the RAT requested weird spec, ndak taut = fair. Hehehehe ... kidding! But if you only rely on Crypton piston whose diameter is 49 millimeters (15 millimeters difference over the piston TIGER) want ... fast!! Piye carane ...? Hmmm seneng we were told thinkers gini Kalok concept we should not stray too far from the design of the Yamaha engineers, pakde Graham Bell said, do not over-enthusiast = modification of excessive ... Once again, Thank God, not for arrogant-vanity, but to enliven the universe that science perbalapan murmerceng still be used to create the race took 9 seconds 200 meters with a capacity of crude So we can move forward together. After all, this is also the result of many learning relationship to various machining experts
Because Miss Broken Gear Ratio
What should be addressed ...? First, basic motor Crypton too old, the first PR machine must be cut in total to check the feasibility of crutch, especially bearing crankshaft, and the whole bearing of transmission, must be replaced new, the choice can wear hi-speed bearings, FAG or SKF. For crutch if there is more money could buy crutch Japan or Thailand steady, that there is a bit much fortune can order a new crankshaft jupiter z at the dealership. But if not, standard crutch back and checked dibalans defiasi crutch swing arm must be below 0.10 millimeters. Replaced new piston, with a density of 43-millimeter leaf crutch, handlebars have to use z jupiter cheaper than having to buy con-Rod's 4ST Crypton. The price could be half bokkk ... the rest is pretty good deed for the mechanical
Crankcase fresh, clean - half of faith
Affairs of the transmission, the ratio re-formulated to link meperoleh crazy acceleration and torque output of the gear 4 to be able yelled at high rotation we use 26/23. Unfortunately the general matter of approaching other event when setting gear ratio is chipped, so was forced to return to the standard, down 0.3 timernya second because the acceleration in 4th gear to rely on very low standard cry-cry ... we as a mechanic put it, could only ndremimil, "best hope, may at best ... "hahahah ... Since the finals were forced to wear a standard overdrive gear we use 13-36, turner overdrive thinned to fit in the chain honda charisma. If only we could use a healthy ratio of the final gear is heavier, is expected to be higher topspeed.
Diperdekat with crankshaft balancer, such as disc
Rotor turner out
Crankcase if still viable, can be used, but if it is too oblak be hunting like the middle of the motor X1 Thailand, or message on a pair of Yamaha Crypton new crankcase, notanya Nested let ga questioned if there was a more Bete Police Seeing us nyeting motor n grounded our motors in the police, but ouch ouch nyeting did not commit a crime, after all the drag racing track in Indonesia is very minimal, unlike the drag racing thailand prima donna! Actually we are the mechanics of this were already looking for a quiet and safe street, anyway emang our work for a living family here really have the heart yes if fine motor racing official, sob ... ... vent colongan hikss Who ever behold also raise your hand?! If racing wildly disciplined pack hehehe ... I agree more steady again if the police held a racing event to accommodate the aspirations of young kids the wrong direction let ga ...
Total Loss System
Done affairs crutch and our friends like the middle of the lid. Blak! -Strong-toned precision! Areas of common coupling is modified, using the tub manual clutch, can the brand TDR, or the direct man-made Yamaha Thailand, you can. Canvass of the manufacturer Suzuki coupling is used, the type of FR 80, but we wear brands Tokaido hehehehe ... or INDOPART lah, already bagusan it, the problem does not exist already mosok bike on the road, Suzuki is still a lot of spare part nyiptain her? if you bought a brand TDR Racing is definitely more stable pitch strength. Pears coupling even so, we rely on the 8000 smash clutch pear's, masyaALLAH, kasian yes we .. hiks ... if you can use pears pengennya Yamaha RX King original clutch, sadaaaappp ... especially if you use pears Yamaha YZ125 clutch, steady ... yet we exist, but the price of hundreds of thousands were not able to reach the owner of the motor which is actually still sitting in school, when yo anake pack Carik, hehehe ... but his name has not been able to work alone so yes gapapa lah, received sober, fortune can be sought later from the boss of the infinite justice of God, Most Merciful ...
Kepikiran to carry a dream ... wkwkkwkw
Balancer we make with weights 600 grams, offset the magnet we change it to a total loss, relying on jupiter z pulser from DC, the weight of the rotor magnet reached 700 grams, by removing the entire magnetic circuit, and perform on turning here and there. The aim lighten the engine speed to be able to reach tens of thousands of rpm with a propeller remained stable. If yes there is more money to buy ignition kit YZ 125, ouch ouch ouch ... try denger geberannya can make horny ... emmmppphhhh Life only once, try a time to feel the pleasure of geberannya alert deh wet dream.
BRT CDI smart click
Piston we all know, Izumi and BRT was never issued a piston racing, how to raise the compression? Memapas head / block as much as possible? Not a good choice. In addition to chain elongation keteng so crazy, top Noken often missed by a mile from the standard, though it's often because we make magic a la RAT Noken when installed in the head that are not precision = boong. Therefore thinned cylinder block 0.5 millimeters, 0.8 millimeters followed by the head is enough. To penetrate the compression ratio of 13: 1, head of the piston we LAS! Yes! Argon welding patched, then our lathe again, until the results of this customized form dum sank into the combustor dome 39 millimeters wide. Dum is bounded near the spark plug gap of nearly 1 millimeter, just not hitting, the difference in left dome pistons with 2 millimeters for not too dense. If it's broke kasian also, we kasian his intention to wait for the money eventually skipper not make ngebenahin liquid-liquid machine, hehehehe ... waiting for the chicken first broke the piggy bank saving pocket money from the school ... hopefully soon granted hehehheeh dapet big bosses can make the motor bore up, terusss vent ...
Hi-Dome Piston Made in RAT
Valve while it's relying on smash with a distance of 4 millimeters pegged safety valve to guard Noken racing waist Made in RAT by 17.8 millimeters, the duration Nested are certainly in close in the area of 70-80 degrees, ex open at 80-90 degrees. Selected valve springs are cheap disposable aja lah CS 1, we do not expect it could be a powerful round, therefore we limit the CDI at 12,000 RPM, if there is good fortune pear propeller engine valve can be opened even higher without the fear of floating and broken-down machine, and moreover back can be made higher up to waist 16.5 millimeters ajiiibbbbbbb ...! While there used to be.
Porting shortened 10 millimeters, the valve shogun
Porting is designed with a peak torque at 8500 RPM, peak power, which stood at 10,500 RPM, therefore we choose a diameter of 21 millimeters ported, if this expert interview form mas mas ... ported ... monggo disekecaaken. 100% flue diameter ported exhaust valve. To generate power might better be achieved with the change in purchasing a new head again for a redesigned sonic valve wear, reduced re-reach a diameter of 26mm inlet and 22mm exhaust.
Block in the press, deck clearance must be 0.8 millimeters
Cylinder head covered with a Torque Wrench, torque each bolt precision
Intake manifold we do not damage the Japanese manufacturer's default configuration, still rely on standard, including lekuannya curves, the bottom of the match with our porting, who met with the carburetor end we welded and drilled diral to be able to re-took the carburetor Keihin PE 28 millimeters. Once again, to save money, but on the other hand we create down draft intake model murmerceng hehehe ... Exhaust is designed so well, still wearing the neck muffler standardnya, considering we still want to see the design capabilities of architects manufacturer Yamaha, given its cylinder capacity not far from standardnya , as well as the initial bend between berharmonisasi ported exhaust with headers, surely the engineers were already thinking about the exact precision air flow. Maybe tomorrow we will desainkan racing exhaust made in RAT full system, with more sloping leheran, hopefully better results, but even better we will not be an architect appointed yamaha engine guard Jorge Lorenzo in Moto GP ... might be appointed to make wiped lackeys part- exhaust wiped the dust let it shine without ya ... wkwkkwkwkw
Exhaust Yamaha Crypton multigrade by RAT
Carburetor, we rely on the manufacturer that created the Keihin carburetor for Honda NSR, with a # 60 pilot jet and main jet # 118, NGK spark plugs escorted c7HSA standards nyampe ga 15 000's. Coil we used the Kawasaki Kaze, who want to contribute coil nggih monggo YZ125, we accept his sincerity may hold deeds not broken as long as we wear racing
Coil Kawasaki Kaze
Noken standard trick by RAT
Racing cepet2an make Noken
CDI, we use the BRT, SMART CLICK pilihanyya type, alert in 2008, deliberately muter-muter find that selling old stock, so cheap anymore ... oh ... oh yes fun story, if you suffer even more cool gini yes: p How could so ... do not so yes-skipper skipper prospective new motor RAT ... hehehehe ... we Ignition Timing 38 degrees BDTC stakes, as well as limit the RPM. Fair was this feature click CDI smart, but if there Rextor or BRT Super I-Max, of timing accuracy will determine the character of the machine can be adjusted to be more hard on lap down, central diputaran stable, fixed breathing at high speed ... ajibb .. the existence of advanced technologies should not be used, not avoided, bother that makes tuh, thanks Tommy Huang om, om Novel Faizal thanks ... you're rock!
Behind the front gear turner, charisma wear chain
I wonder what ... well maybe not lots, because we humans are far from perfect, because people can plan and tried, but God disposes. At the end of the race when we come home correction, the piston begins to crack exposed to compression that does not fit with pertamax fuel, benzol should ask ... do not miss a plus if the jockey gear ... ouch dik. Anyway, if the drivers gear already miss more than 2 times, please see if the engine disassembled valve is leaking or crutch is no longer center. Our experience of shared learning is used so as not to be repeated.
