Yamaha Mio 2008 (Jakarta)

Riset Kelas 175 CC

To enliven the racing 175 cc class skubek open, aka Saputra Eksa Medi Medi Speed of getting ready early. Get ready ...!

Tuner from Jl. Harsono RM, Ragunan, South Jakarta was trying to use Tiger piston diameter of 63.5 mm obtained easily. However, increased engine capacity was 183.3 cc. Well, violating regulations dong?

In research, Medi not want to admit responsibility. Because of this new class and get off at the circuit design unknown treknya, he makes two models of the engine. Like the standard model of the dome design and a bathtub.

Two models were intended to look for better performance. Thus, the team was able to modify the appropriate data and do not need to touch on the circuit.

As a test, the cylinder block in the content Mio Honda New Tiger piston diameter of 63.5 mm. Incidentally the same diameter while the piston pen to change the piston head. Also changed gedein hole boring and crank-case of a 61 mm 69 mm.


Later when I met settings, replace the piston according to regulation 175 cc class. He said disposable piston Honda GL-Pro 62 mm diameter platinum. The result was the volume of a cylinder 174.7 cc, "explained the father of this child.

Because Medi dome makes two models, automatic piston head in two blocks necessary adjustments. As usual dome model, so do the trimming 12,5:1 compression outer ring around the piston head 0.5 mm. To form a circle 54 mm in diameter. Dome was a bathtub, his head circumference dipapas by leaving a 0.8 mm diameter circle in 52 mm.
"Because the dome is different from usual model dome bathtub models, no doubt on the corner of the dome valve boss bathtub I slide into. Problem degree secret. To be sure, the rest of the distance between the valve settings in and out in the dome of about 0.5 mm to avoid collisions when they overlap, "said Medi.

For the supply of fuel because the cylinder was distended, the pinnacle of the standard back changed. Just about the duration or the duration of the valve in and out open-close, again dirahasikan Medi. Wah ya cheapskate?

Just as a benchmark, Medi admitted that back for a high dome ridge in the bathtub dipapas be 26 mm by 19 mm thick waist. Out back was the pinnacle height 25 mm and 18 mm thick waist. It seems too after a lap top.
