Shogun Drag And Daily

Shogun Drag And Daily
Hello OP, I'm your fan from the Pacific Islands. 125 Shogun bike, want kubikin Teach me tight .. yes .. Because I do not want dioprek by the workshop. Kerjain themselves better than cheated again. My question;

1. I want to bore up the engine for drag. For a minute there I heard Dragbike event in the Pacific. Cuman because this is the only bike so it should be used daily as well. Most sip piston wear what? How to get in and exhaust valve? Teach setting off the carburetor in order to breath, then?
2. Is the gear ratio to be changed? So how the comparison?
3. Replace the coil and CDI should wear what?

Never be fooled action of an individual does not mean that all pebengkel workshop had the same character, Sob. Try it play to the bike shop the other, certainly more honest than the hokey hooked.

1. Shogun 125 dibore up for drag but safe for daily? It would be difficult ngejawabnya. Make follow-drag it means the machine is set up for a certain distance (201 m). For example, the official drag bike so that the maximum spec change was quite extreme. This principle is far different from the daily motor which often can only explore the performance of the engine in the lower and middle rpm.
   Another story if the designation for a great performance at least daily but not far behind than drag racing.
   Uh, by the way, Shogun 125 dibore up means penetrating capacity of 130 cc. For info, stride length was 55.2 mm Shogun 125. Create example, if only 150 oversize piston fitted which means the piston diameter 55 mm, the cylinder capacity to 131 cc. The problem, for it is already past cc regulation duck Class 4 stroke 125 cc in Dragbike race, which is stuck in 130 cc? Worse, if the capacity for more than that, the motorcycle can only compete in FFA Class 4 stroke s / d 250cc! Unless there is a wide opening of the new race class Ducks 4 No Class FFA s / d 200cc kinds of drag in Yogya or Class 4 stroke Duck Tune Up s / d 155cc kinds of drag in Gresik.
   Of course another story if the purpose is a buddy drag Bali aka wild racing.
   So, if that is what want, use the OP advice piston Suzuki Thunder 125. Diameter is 57 mm, Sob. That means the Shogun engine capacity 125 cc buddy be 141.4! Advantages of using piston Thunder 125 is on pen size piston, exactly as Shogun 125 which is 14 mm. So do not hassle application.
   It's just to set it up, there are several things to consider in order to succeed overbore. First, the boring Shogun 125 must be replaced. That's because the outer diameter of 60.5 mm cuman boring. Once entered piston Thunder 125, thickness 1.75 mm boring live.
   Figures refer to the thickness of the liner that much too hot R2 daily motor. Seher easy expansion, might be prone to jam. Should still at least 2 mm thickness. But it is a bold claim to some mechanical Kolter apply to the remaining liner 1.5 mm. The choice of course back to yourself buddy.
   Direct play Kolter hell might be. However, because the rest all that thin, sure pal must Kolter mechanical tiller can do a good job.
   Oh yes, plus piston ring piston Thunder 125 plus pen can be redeemed with money Rp 245 200. Meanwhile, if my friend did replace the boring costs around Rp 100,000. Uh besides piston Thunder is no other option ie use of aftermarket pistons for special Daytona Shogun, Smash, until Shogun 125 available piston bore up 58 mm. Complete with gasket priced at Rp 300,000. If you want, direct contact Daytona Nagata, Jl. 84B Flower Market, Surabaya (Sunday open), telephone (031) 71411362-71612023. Course for the Daytona piston liner remaining standard thinner, live 1.25 mm!
   Problem affairs valve, this depends on the purpose pal. If you want to pursue power in the upper rpm is most sip valve sizes expand.
   Well, after the bore up to 140 cc. So that was in the torque the engine is under growing craze. But this short and make breathing machine. That's because it's too fast bergasing engine to higher rpm.
   In addition the gas velocity becomes too large for the size ratio of the valve area than the entrance area of ​​the piston. With the carburetor fuel supply technology, this is a big problem. Because the fuel supply will be difficult mengabut and disturbed.
   Because of the negative effects of the other factors, especially earlier in the cylinder head should be aligned. For daily than hell, the application adequately served Thunder 125 piston valve has a standard spec exhaust and intake 21 mm to 25 mm.
   Once found path is rather long, it will feel once the engine runs out of breath at high speed. Therefore inevitably, the valve shall be raised in diameter. At least the valve combination 28/23 mm could be an option. Valve option that many on the market. My friend can use aftermarket products from DTN brands are sold Rp 110 thousand, Daytona is Rp 150 thousand, TK about Rp 275 thousand to Rp 250 thousand TDR. In addition there are also aftermarket kanibalan of Honda Sonic the berspek 28/24 mm, which is valued around Rp 200 thousand. Pairs of stolen goods or CS-1 with spec 28/24 for Rp 120 thousand.
   Applying big valve simultaneously increase the volume and area of ​​the combustion chamber that improves the engine's performance, especially at high speed. Of course this was followed by back in order to change the duration longer for the engine breath much longer. The key is structuring compression.
   Still dealing with it shall replace the valve springs with congenital Shogun 110 minimum.
   As for the options are carburetor Keihin PE 28 or better known as the carburetor NSR SP, cost about USD 600 thousand.
   Problem nozzle setting affair, this depends on changes that have been made. But as an example, if pairs of Thunder 125 spec piston valve is standard then the pilot nozzle is in the range of 42.5 while the range 115 main jet.
   
2. Affairs or the final gear ratio final gear once again closely related to the changes made. Again for example if the machine is fitted with a valve piston Thunder 125 standards then the final gear is okay to use the standard. That's because the gear ratio Shogun 125 classified as severe. Especially the 4th gear that ngedrop really.
   However, for purposes of relative path length, front gear 1 may be diminished in the eyes or if the rear gear can go down to 2 eyes. In short final gear made more severe.
   
3. Standard coil is still okay for bore up engine. If pengin powerful coil pairs YZ be valuable in the range of $ 500 thousand. While the matter of CDI varied choice, if the price of the benchmark for the range of USD 350 thousand, my friend can use BRT CDI type of Hyperband or XP. If there are more budget being allowed to use CDI Rextor retailed $ 500 thousand.
