So I went to yamaha dealer and told them to check my valves again. I said to myself that this time i will watch the guy do it. So he unscrew the valve covers and the two little cap. Then he started fiddling around the valves with a spanner. When I asked him if he needed a feeler gauge he laughed and said that he doesnt need it. He explained why but my Chinese isnt good enough to catch everything and the result is that i have no idea why he didnt need that gauge. 15min later the job was done and he said its all good.
Im a bit confused, is there a way of adjusting the valves without a gauge? My YBR ia a 2012 model so maybe on the newer bikes this problem is solved some other way? I realy have no idea...
