HELP : How to adjust Carbs 2000 R1 : Yamaha R1 Forum

Daedalus · 09-04-2007, 03:34 PM

First off let me apologize for being a noob. I am having trouble with idle on my r1. Cold start its perfect runs great just a tiny bit over 1k rpm at idle. 5 Mins of riding and my idle sits at 2500. I have tried adjusting the carbs a few times now, but I must be an idiot. To reach the screws, I have the bike off, gas tank flipped up, air box off, and i have to twist the throttle to reach them right. I know I'm retarded, but how can you adjust idel without the bike running? Is there a trick to it I am missing.

PLEASE if anyone could give me a couple pics and a write up on proper stock carb adjustment I'd be forever in your debt.

Thanks in advance,
Desperate Noob

There is an idle adjustment knob on the left side that you can reach without having to remove anything.

you are talking about the synching screws between the carbs! that is not the idle adjuster. do a search it's been discussed here plenty.

As already said, there's a small black knob on the side of the bike located somewhere under the tank. I had an 02 but can't remember exactly where it is. If you turned the screws on the carbs you'll have to take your bike to a professional to re-adjust each individual carb.

you are correct, except the knob is cad/zinc colored.
