Bike Runs, but Cyl. 2 seems dead

This will cause the high idle and reluctance to fire fully on that cylinder as it will be drawing in mostly air and not a full fuel mixture.

If the intake boots were removed from the head you probably have a air leak at the head. have you tried spraying wd40 around the boot while running to see if it picks up rpm? Might be worth a shot if the cleaning doesn't fix it.

I have tried this many times, and each time I have had no rise in RPM.

I have an ultrasonic cleaner at work, and I will clean the carb bodies ultrasonically this time. Should make them like new right? I really hope to get this thing going come riding season!

Wow, blizzard. Wow. Most of my family lives 1 hour from Chicago. They love that cold snowy weather. 'Lake effect snow', '25 degrees below zero', and so on.
California has its bad points (the state is broke, highest state income tax in the entire country at 13.5%, tree huggers, yada yada). However it was partly cloudy in the morning then sunny and mid-high 60s today. This is a dang good time to clean those carbs. Let us know when you get back to trying to run it!

Yea, last year at this time it was close to 70 degrees! Figure that one out.

I got carbs 1 and 2 disassembled and there is crud in both! Not much but enough. I am having the carb bodies ultrasonic cleaned. Should I had the bowls as well? Is there anything I need to remove from the body or bowl? There's some brass looking shaft in the bowl, will it be ok in the ultrasonic cleaner?

That brass tube is the overflow tube. Be gentle with it as they sometimes crack. If it cracks or breaks fuel will leak from your overflow hoses even when the fuel level is set at the correct height. I would clean the bowl using some carb cleaner and a flux brush. Ed

Ok I'll leave those out of the ultrasonic.
Everything is removed from the bodies that I can remove, so they should be ready to go right?

Ultrasonic is out of the question right now, so I picked up Berrymans Chem-Dip. I am very very pleased with the results! All of the carburetors were varnished and grimy, and the drain holes were all plugged solid. After a 30 min. soak, a small prick with a paper clip and the varnish clogging the drains turned to mush and washed away! They are starting to look like new.

Before, bad iphone pictures, but I think it gets the point across


After!


I just realized I didn't take any pictures of the float bowls, but theyre just as clean.

I think this will solve my misfiring issues.

Before you assemble the carbs make sure you spray carb cleaner through all the small passagways making sure they are all clear.

Did that on the 2 I have finished. All clear and spraying clear.
