Modified Yamaha Lagenda 115Z with 32mm UMA Racing Carb and RB SP399 Wheel

Modified Yamaha Lagenda 115Z

This is a test bike from Maju Motor. It is fitted with 32mm UMA Racing carburetor with is way much bigger than the original stock carburetor at 17mm. Using larger carburetor is one of my favourite modification since this will definitely increase the horsepower and torque at the same time. Fuel economy is not in the equation here since it is not being considered. I still remember my Honda C70 that I use to have when I studied at university in Johor, that is fitted with RX-S 100 carburetor at 22mm, I think. The power at high RPM is enormous and surprisingly, the stock cylinder and casing of the Honda C70 can bear the torture.

This red Yamaha Lagenda 115Z also fitted with Racing Boy SP399 3-spoke wheel in white that matches the overall look. SP399 is one of the most popular wheel in modification scene since it is lightweight, high quality, easy to clean have and nice style. Anyway, this wheel design is not originally from RB since it is being used as a stock wheel for Yamaha Y125ZR in 2001 by Enkei.

This bike is still in progress of modifying, so, I shall visit the shop again to see what it looks like when everything is well finished and ready to run.
