This is a big bore kit for the 50cc vertical engine. The SPL Big Bore Kit includes the SPL cylinder head with big valves, large diameter port and optimized combustion chamber shape. These variations broaden the tuning menu for the APE50 series vertical engine. The parts that are not included in the kit are basically reused stock parts.If the parts to be reused have significant deterioration such as scratches, wear and tear, replace them with new ones.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
I opened the 4th Engine for the first time. It was a long-established store truly made it possible to organize it with confidence! I think that it is good to refer to KITACO's cheat sheet or Net movie for the first time.View Detail
All were constructed by themselves.Although advanced looking at attached description and Net the start of , when constructing the time of taking down an Engine, and an Engine, it had a close game considerably.(^_^;). As a result of not finding how to construct a Cam chain tensioner again but applying power by force, the crack has entered and bent in the Tp part.As for the Engine, what started seemed to be out of condition. Although the [Torayuki volume] which has come out of the KITACO is purchased there on the next day and being reconstructed from 1, it is better for there to be this absolutely.It could work to the Smooth considerably and was able to construct certainly.He repented [ that what was necessary was just to have carried out by seeing this from the beginning, and ].I consider an after Torque wrench as it is better to be.Since it seems durability and on moral stable that it is very well with considering the thing of the future if Torque management especially (smile) with a positive Engine to which 20 Nm was not found [ how much ] at all when it was an amateur like itself has not been performed ... Although it is a direction of > engine performance,A difference is first known clearly in the case of a KICK of engine start.As the compression ratio has also gone up, it becomes heavy fairly.Even if it runs, compared with the time of 50 cc, remarkable acceleration is carried out even from low rotation.Although the kana which does not suit at a little time of 50 although it was changing the Front sprocket into -> [ 14 dishes of ] 16 dishes from the first was thought, after using 80, it became just right touch.I think good kana, even if it uses high-speed slippage to a slight degree.View Detail
[Webike Monitor] Although it was the amateur, it was able to construct somehow, carrying out a staring contest to a waist top key.When it rode, it became touch as if it became an Engine of the different thing completely in 50.A Sprocket follows steadily at least 33 dishes of pure back for a front.Even if a front raises about two dishes, I think that it is completely calm.If a High cam is constructed to this, in addition, they will be means.View Detail
Since XR50 motard of normal was too powerless, it carried out bore up and made it 2 sorts of moped registration. The selected kit is an 82-cc light bore up kit of a kitaco. A price is also handy. Although attachment was performed by itself, it is necessary to take down an engine from a frame first. It was like the half of work finishing, if this is fairly troublesome and it finished taking down. If recombination of a cylinder and a piston is a person familiar to an assembly of an engine, it is completed without suffering troubles so much. However, it is better even for the however familiar person to have placed the service manual at hand, and to refer to it. In fact, I also do without a manual and fail in the tension of chain tin SHONA. It has ended up constructing twice. the response (a pair of shoes -- responding) of a kick also becomes heavy, and those of the engine which it finished setting up is reliable. A shake down is carried out firmly. After a shake down finishes, when a full throttle is given, normal is acceleration in a completely different class. However, since intake air is restricted by the normal cab, even if it changes a moderation ratio, 70 km/h is as hard as possible. Although torque went up by the air-intake-and-exhaust system of normal, a suction amount is insufficient and it does not turn around high rotation. If it asks for the engine performance beyond this, reexamination from the air inlet of an exhaust air cleaner to a muffler is required for exchange of a carburetor and a camshaft, and it. It is better to be seldom avaricious, although I aimed at power up further by a carburetor, camshaft exchange, and reexamination of an air-intake-and-exhaust system after this. Since power up becomes in exchange for durability, it is good there, then to stop. Don't see the thickness of a cylinder sleeve or don't expect durability too much.View Detail
