Yet another carb question
I'm having a hard time getting my stock 2008 KLR 650 up and running again. It sat for about 6 months. I figured all I needed to do was clean the carb. Either I'm missing some dirt, or there's another issue. I've cleaned a number of single barrel carbs before this and have always had success.
I've poured through the forums, but I'm just getting a little overwhelmed with all the info. Was hoping I could post my specific symptoms and get some input from you guys.
Here's my process so far:
Cleaned the carbs manually with carb cleaner and compressed air. Re-assembled. Installed.
Bike started right up. Seemed ok then started to falter at idle. Gave it gas and it smoothed out around 3-4K rpm. Still a little rough, but ran.
Choke (enricher) didn't seem to make much of a difference.
Pulled, cleaned, reassembled with a stock rebuild kit from All Balls (both jets, float needle, fuel mixture screw, spring, washer and o-ring), reinstalled. Same thing.
Pulled, cleaned in my (newly purchased just for this) Harbor Freight ultrasonic cleaner with 50/50 pinesol and water. Followed up with clean water to rinse pinesol solution and blew out with compressed air.
Installed newly purchased brass enricher nut.
Capped 1 vacuum nipple and left the other open so I could cap with my finger.
Attached a hanging auxiliary gas tank so I could work on it without messing with the regular gas tank and associated petcock/vacuum issues.
Installed new air filter.
Exact same condition.
Manufactured and installed an adjustable idle mixture screw.
Ran exactly the same. Even adjusting the idle mixture screw while running from 1 turn out to 2.75 turns out.
Once again, 3-4K rpm seemed smooth. Closer to idle, rougher it got. Barely any throttle runs really rough. With no throttle it dies.
Last two bit of info-
1. I've run a lot of bikes in garages. Even with the garage door open my eyes stung more than usual. Seems like it was using a lot of gas, but I don't know how to quantify that.
2. Brand new gas from a brand new 2 gallon gas tank with a little seafoam added.
Any input you guys have would be greatly appreciated. Thanks in advance.
