Please notice that Yuminashi don't have a 175cc kit at this moment, so it's hard to sell something if it isn't available.Mgalutia88 wrote:To those that have good luck with yuminashi good for you. There are many people including on the grom forum that have had issues with yuminashi. Including some bore and piston sets that did not match and caused engine failures.
I requested information on a 175 cc yuminashi big bore kit from PCX racing in France. Keep in mind that PCX racing sells the 164 cc bore kit. I was told that PCX racing will not sell the 175 kit because of poor quality. What does that tell you when their distributors will not sell some of their parts...
Our new pistons for the 175cc will be available in something like 2 weeks.
Until then we will never have sold 1 kit 175cc for PCX.
Concerning the issue with the 5 pistons at the start from the 150cc cylinderkits for MSX/GROM125, all 5 pistons have been replaced in warranty and no issue have been reported so far.
Even better, Travis Butler who is one of the customers who ordered such a kit and showed all the details on internet have installed later on our 160 Ultimate Kit for MSX, and his experiences about this kit you can read over here http://www.hondagrom.net/forums/13-grom ... sults.html.
If a part isn't functioning correct, you will be replaced, and herewith we are the only company in the world with high performance parts for PCX, MSX or Monkey bikes who does this.
