Hey folks, I need to replace the temp gauge on the NC29 race bike I've just sold (the sensor on the HRC unit I have doesn't fit the stock radiator on it now), but with the bike and Haynes manual in Aus, and me in Amsterdam, it's a little difficult to measure or look it up! Can anyone help me out with the thread size I need for a replacement temp gauge into a stock NC29 radiator?

For the faithful, fear not, I'll be back on an NC29. There's a frame, swingarm, subframe, and half an engine waiting for me when I eventually head back home.

Cheers,

David
