forden - here is a link to the dohc carb cleaning thread I mentioned in the previous post:

Reading the whole thread will be beneficial, but here is the direct link to the MacGregor carb cleaning manual:

In the thread, there are two methods outlined on how to clean the carbs.  The first doesn't involve separating  bank apart, and the MacGregor one does involve separating the bank.

The MacGregor method is more time consuming, but you end up with cleaner carbs.  The method where you don't split the bank may be enough to get you running.

Both methods go into detail on how to bypass the air cutoff valves.
