Seconded. It sounded ok to me in the vid, should have left it at the same tickover and tried it out afloat before changing idle speed.

Going into gear tends to sound a bit agricultural, but that's normal too. It's better if you don't hesitate, just drop it straight in. There's quite a nice, positive change in resistance between selecting a gear and picking up the throttle at least on ours so it's quite easy to do. The couple of Yamaha and Honda throttle units I've used had a narrower idle 'detent', which was a bit harder to use.

Thanks James

I don't know how they compare to the RIBnet favourite Yamaha two-strokes, but I like them.

if I remember correctly yours is the two cyl, single carb. If you set it up at eight hundred rpm or slightly higher in fwd gear, and the idle air mixture one and a half turns out from lightly seated , you wont be far out on your settings, when set up correctly there should be about a two hundred rpm differance between in gear and nutrual .
