Hi all,

Long story short, I seized my top cylinder then rebuilt both top and bottom.
I screwed in the air screw on the top a 1/4 turn and left the bottom as the bottom is running fine. The spark plug on the top cylinder is a little reddish brown which tells me it is lean still.

I have a sticker on one of the fairings which is mostly in japanese except for the spark plug codes which is english. Now I was too busy stuffing around in japanese class to learn anything but at a guess it looks like it says to have a BR10ECM on top and a BR9ECM on the bottom. Am I even close on this?

I was just guessing that the top may be a little too hot of a spark plug.

I would send a photo of the sticker but I am a crane operator and the only computer I can competently use is the ones in cranes.

I am praying someone else has the same sticker.

Cheers all in advance.

Andy.
