Yamaha Mio Drag Bike, Thailand Study Result

 of study in Thailand, one of them is the selection of the piston. No need anymore to rely on bore piston or piston aka big. But, simply copy the piston which is widely used by Thailand for the race tuner FFA.
Piston LHK brand used 66 mm diameter, try dependable Ismail Harjono, Tunner Harmony Monster Skutik (HMS) from Solo, Central Java. That outcome study last year to Thailand, all with automatic drag racing there.

The result is not indeed useless. Ismail able to deliver Yamaha Mio which spurred Rico is perched on the podium Boncel honorable title YSS TDR Comet Drag Bike Championship DID 2011 in Semarang, last Sunday.
Tracks straight Circuit Tawang Mas, Semarang became a witness greatness Mio continues that since the allowance is perched on 3 big. "Time to Thailand a lot of chatting with the mechanic there. I try to apply in this bike, "said Ismail.
Previously, Ismail choose to play with 70 mm piston for pursuing large capacity. This piston has a piston type races like the Special Engine (SE). The bottom of the piston is shorter. So, unlike Tiger Piston Honda or Yamaha Scorpio classified as long.

In fact, this bore applications, he said there were many changes. Namely, the desired power. If the previous power seoalah shouted and ran out of breath at a distance of 30 meters before the finish, not anymore.
Shouted a machine, can now cross the finish line. "When using 66 mm piston, until the finish there was still some power. This is actually a character created to be automatic, "beber Gembor closest call.
Use a large piston could actually outsmart power. But, the power under a mess because of too wild. Create pursue maximum capacity, 66 mm piston is combined with a stroke length of 86 mm.Stroke is the result of congenital crankshaft from Thailand as well. Yup! 've Received so!
With the replacement handlebar piston having a smaller pen crankshaft, big end automatic can be shifted even further. That way, the total contents of the cylinder which applied in this sleek Mio screen, a 295 cc. According to Tunner 32-year again, the capacity is already considered sufficient!
To Thailand again? (
