the airbox MUST be on if you want to get it to run.Too much air and it will not even start!Put your box on and see what happens!

Hair dryer works great for heating things up also.

I always put a little wd-40 around the boot flanges and they slide right on.I think from what you described in your other post everything will be fine once you get the airbox on.Be sure to oil your air filter also and make sure your airbox has no leaks.i have to sync my carbs but it's to darn cold out today to worry about it.Sunday looks a little better and there is days of rain coming so i need to sync and ride!Did you replace your intake boots and 0-rings?If not check for air leaks if it happens to high idle after warming up. PM me if you have any problems.

If you just want to check to see if it is running reasonably well, you can do it without installing the airbox.

You need a decent-size shop rag and two zip-ties about 8-10" long. Fold the rag in half, drape it over the carb inlets. Zip-tie the rag around the throat of #1 and #4 carbs to hold it in place. If the rag is stretched across #2 and #3, it is close enough for this test. Start the bike, see if you can get any better than idle speed out of it.

This provides just enough restriction to smooth the airflow to get it to run, but I would not run it this way to do any readings for jetting purposes.
