One more but not from Mayora! But preparations for the jump in the 175 cc class, has done Komeng Deny alias Mansur. Doi, mechanical Motor Clinic (CM). This time, Yamaha's Sandy seriously worked to jump on a new class racing skubek.

"Research continues deh, while this class has not rolled it," said Komeng which to carry the flag of the class Petshop FT Youmbla Clinic (YPFTC).

Well, there was some research done Komeng. If anything, the process is done on an intercross engine tuh. Yes, intercrosses between two brands of manufacturers.

Confused? No! Continue reading until they run out deh. Starting from the first intercross yes! By increasing the capacity of the cylinder to firmly touch the 175 cc class, Deny raising measures about 10 mm pistons. Dilakoni to pursue it for a longer stroke.

"Naikinnya, use a pen stroke Kawahara 5 mm. Just that alone, enggak need big slide end," said the young man's heart good. Lho kok youth? Yeah, right Komeng unmarried. Hi .. hi .. hi ...

Go! With pen method, now measures 67.9 mm piston so. Iya dong, up and down adds a 10 mm. Mio original stroke plus a 57.9 mm, 67.9 mm dong so. Begitunya increase was accompanied by an increase in stroke piston diameter. Yes, the piston is taken from the 125 oversized Suzuki Thunder 0. "Use size 57 mm," said Komeng who had a workshop on Jl. Squadron, No. 14, Halim, East Jakarta.

"MX handlebars of the piston is longer than Mio. Also if not replaced, the piston can be fixed pen with crutches as the Ttitik Dead Down (TMB)," he said. This is practically intercross.

Adjusting the diameter of the piston which is only 57 mm, valve EE brands that had a size of 31.5 mm and 25.5 mm dipapas join. The diameter of the umbrella valve gambot so dipapas for valves 28 mm and 24 mm in valve for waste. In order to bejaban on the short track.

Now, with open-close valve is originally from the Toyota Vios in Thailand, the noken alias as well as play back duration. Unfortunately, Komeng enggak really know about the duration.

"But clearly, bumbungan valve into the valve and dispose of this K3 type Kawahara dipapas about 0.5 mm," said Deny is pleased with cropped haircuts.
