I have A 150 & a 70 I had bought for my 5 y/o son and my wife. So far I have been very pleased with the bikes. If anybody has a 150 yamato could you please tell me where the tube (looks like a vent tube) that one side is plugged into the valve cover (or front of the motor) and the other side is not connected to anything. The hose does have a small spring clamp on the other side like it would go somewhere. Also, I here about a restrictor plate for the 150. Is there one in the air box? I know my sons 70 had one but his air cleaner was under the grill at the front of the bike (easy to get to). The 150 air box doesn't look easy to check. If anybody has first hand knowledge of removing a restrictor plate out of a 150 please let me know and i will make a attempt to get to it. Thanks[img]i/expressions/face-icon-small-smile.gif[/img]

 

There is no restricter plate on the 150, at least not on mine,and I have looked. As for that hose coming off the valve cover I have not found a place for it either. I would assume that it should connect to the carb. or air filter box. I just zip tied it out of the way.

 

I did the same thing with the hose on mine. It seems it should go somewhere though. Thanks for the info in the restrictor plate.
