(coop427 @ Mar. 28 2007,05:40) I just did a tb sync on my busa yesterday and the manual and jinksters pics are not correct. The service manual shows the sync tool being hooked up to the ports that have rubbercaps on them, the only problem is the bike doesn't have these ports only the ports that the vac hoses for the map sensor hook to. Also in the pics jinkster posted he shows to hook the map sensor to the extra port on tb #4 while performing the sync, but if you do this it doesn't have enough vac to run right and idles rough or stalls. I had to put a tee in the map sensor hose so I could hook it up to #1 AND #4 so that the bike would stay running to perform the sync. I don't know what year they changed the TB but I have an 03 and it is different from the pics in the service manual. Like I said before it doesn't have the extra ports with a rubber cap on them.
