Naraku 50cc Cylinder Kit for Minarelli Yamaha Vertical AC 2T Engines for 1988-2001 Yamaha Zuma, Yamaha BW 50
The Naraku 50cc cast iron cylinder is a an affordable and robust alternative for those who are looking for a replacement top end due to cylinder or piston damage. The power output is slightly higher than that of the original cylinder. All in all, a very good quality kit for the price.
Supplied with barrel, piston, rings, pin, clips and gaskets. Original cylinder head may be retained.
Note regarding installation:
Please be careful when assembling the piston rings, the "T" or "J" mark on the piston ring end must be facing up.
Only for pre-2001 Yamaha ZUMAs in the USA and the BW in Canada. These featured Vertical Minarelli Air Cooled 2T engines. In the USA 2002-2011 Zuma versions use the Minarelli Horizontal 2T AC Engine. 2012 and later Zuma are called the Zuma 50f (which replaced the 2-stroke version), both 4-stroke fuel-injected models. We call this the Minarelli 4T on the Racing Planet USA website.
