New setup way off.

[brock42]

Just went back over everything I reinstalled the 27.5 and she's idling ok now but I have my air screws 1/8-1/4 turn out from seated and it is bogging a Lil off idle and the idle hangs just a fuzz.air box is not installed yet

You cannot fine tune the motor without everything assembled.

If the idle hangs, it's likely a little lean. Installing the box and filter will make it richer.

Ok. That's what I was wondering I'll try that thank you.

Have you tried it with complete air cleaner set-up on ? Have to tune the way it will be run. Did I read that you installed new reeds? Leak test after? Double check boots like Tricked suggested. While running spray with starting fluid or such, or unlit propane torch.

[brock42]

I didn't install new reeds just replaced the pipes and added airbox. I tried it with the full air filter setup on and at 2.5 turns out on the air screw it boggs out. If I start to turn the air screw back closed the throttle response starts to sharpen up but once I get closed it dies out.

I reinstalled the 30 pilots and at 2 turns out it boggs off idle. If I run the needle in until seated and barley crack the needle back open the rev gets better and the off idle bog is almost gone. The pipes seem to have somewhat of a pop to them. Don't know if this matters or not. If I back the air screw way out the pop starts to go away. I took it on a ride and it pulls hard from about 1/4 to full throttle  but seems like it's loading up and wants so foul out at low rpm.

Pilot is too big. Go back to the 27.5 and tune more on it.

[brock42]

27.5 seemed to act the exact same should I go back to the stock 25 pilot 

[locogato11283]

It can't hurt to try it, but typically pipes with an air filter requires 27.5 pilot.

[brock42]

It seems that adjusting the air screw doesn't change the idle any to be able to tell what I'm doing. 

[brock42]

I adjusted my float height to 21mm. Could float height cause it to act up. My clip is on the middle setting of the stock needle also.

You need to change one thing at a time and see how it reacts.

The air screw shouldn't affect the idle, but how clean it revs from an idle.

It sounds like with 30 pilots and .5 turn open you were pretty close.

[locogato11283]

The needle will be your last adjustment for fine tuning.

I think I would put the 27.5 pilot in and get it close. Then start adjusting the needle.

[brock42]

So does screwing the air screw in lean or richen the mixture. It comes off idle best when the needle is almost closed.

Air Screw in richens, it is an air screw, it adds air, if it is best almost closed your pilot is to big. Remember to wait at least 30 seconds every time you turn the screw for the motor to normalize. don't turn more than 1/2 a turn at a time and do both the same.
