Last year I had to adjust mine out 1/4 turn and it ran well at 1/8 throttle. This year so far I have them out 1/2 turn and it chugs 1/8 throttle until about 20 minutes later when the engine is warm enough to heat the intake air enough to richen the mix. How far out have you guys had to turn the pilots past the standard 2 1/4 turns out when it gets cold where you are to get it to run right at 1/8 throttle? I have no mods. I verified the carb sync and it's right on.

Thanks.

 

3 turn's out work's on mine, maybe 3 1/2 in the winter........

 

anyone else?

 

Mine are at 3 1/2 turns front and 3 3/4 rear.

 

How did you make the determination to set them differently from front to back?
Thanks.

 

I made the rear a little richer because the main jet is bigger on the back cylinder and it tends to run leaner. Don't know if it really makes a difference, though.

 

do all the stock 650's come with the carbs set at 2 1/4 or does it vary? I think mine may still be a bit lean, as it still requires a slight slight bit of throttle to start, even with the improvement of turning up the idle. I checked my back carb, and it was only around 2 turns out, maybe even a little less. I'm annoyed because as i was turning it the screwdriver slipped as did the light and I may have lost a bit of the count on the screw turns [img]i/expressions/face-icon-small-blush.gif[/img] Anyway, I screwed the back one in all the way and then backed it out 2 1/4. Hope this is ok.

How many turns out do you guys run on your stock p650's?

 

NovaKaw650,

Where did you get your Tiny Tach and do you like it? What was it like to install?

Mine are set at 3 turns out. Starts w/o giving any throttle, wouldn't do that w/stock settings.

 

I found that both of my screws were only about 1 3/4 turns out , either from the factory, or the dealership when they built it. Surprising. I set them both to 2 1/4, and am going riding tomorrow. We'll see how she runs and starts. At first I thought i'd set them both at 2 1/2 or 3, but since they were so low to start with, I figure I'll experiment incrementally...
