How long does it stay bogged down? Does it gradually pick up rpm's? Does it sound like you have a "dead" miss at the 2000rpm mark? Please, more info would help us help you.

I would verify sync and linc. You may have excessive advance before the high speed jets start feeding enough fuel. One or more jets may be fouled as well causing a similar problem. When were the carbs overhauled last? When was sync and linc verified last?

dont really know about the last time this was done linc & sync but is this tough to do by yourself i have the manual and why would the link & sync just go bad ?

It is more likely that fouled carbs are the issue. Sync and linc needs to be checked periodically as linkage wear points cause slop over time. If you don't remember last time carbs were rebuilt or if they were never done, I would start there. Has your WOT remained the same or have you lost some over time? Has fuel pump ever been touched?
