    3 turns bro. Turn it all the way in, loosely because these are delicate springs and screws. Grip the screwdriver with your fingers only
    Then go 3 full rotations out. If its still a bit rich at idle when you get it going again go another 1/2 turn in.

    Carbs all cleaned up. B4 I started I noticed when I pushed the rubber runners they got stuck up there. But after the clean it is now smoothly coming back to start position .

    Wondering if this was the primary cause of the reving problem.

    Should I do the valves check ( which means radiator out etc) or i put this back on and test it out before I move further?

    Hmm thinking about just checking valves since its all open. Keen to do it but need an opinion on whether to test the carb first

    Do the valves man, hard work has already been done stripping it down. Won't hurt to change your coolant either

    Blue RTV Silcone. You won't find new ones anymore. Unless you dont mind waiting a year for Yamaha to order you one...

    Your manual should show you where all the timing marks are.
    Is it still bogging down at 8000?

    Dont have a fzr250 manual (no english version) so using a fzr400 manual. Still haven't put the bike back together since I opened it up. Will do some research tomorrow and measure the valves.
