What's this?
« on: January 21, 2009, 08:30:53 am »
It's not GYT kit (alloy liner), is it YZ250A? Did the YZa come with a spares kit?

YZ-A has reed valve.

The lack of liner AND piston port is really weird - I didn't think that such a combo existed.

The good thing about telling the truth is that you don't have to remember what you said.

Nathan, When I was restoring my DT1 I was told by Col Iskov, the parts manager at Yamaha Australia that they made piston port GYT barrels in both steel liner and chrome bore guise. I wrote the numbers down somewhere but in my disorganised world I've lost them. That information surprised me as I thought they only made chrome bore reed GYT DT1 barrels. Graeme, the 214 prefix is DT1. I found a NOS GYT cylinder listed for $250us........  http://www.boats.net/parts/detail/yamaha/Y-214-11311-70-00.html I've never dealt with this crowd and have no idea of their reliability or accuracy.
For what its worth, my RT1 GYT piston port barrel is chrome bore.
