Sorry to hear that you've not had any help.
This site is for anyone to help anyone.. Given their own experience or skill set.
Perhaps you should specify the particular model with the problem
.
You might also find more
pertinent help if you could find a forum on the internet.
There are many forums on the internet for almost anything you can think of.
In
google search, (
www.google.com) type the make model and the words "help" or "forum" and see what come up.
From the very brief details you did include, not clear what "intake boot" is exactly, but have you tried a clean air filter?
Otherwise I'd look at the timing advance mechanism. The timing might be perfect at idle, but if it does not advance correctly it will bog down in acceleration. If the timing advance is operated by a controlled
vacuum, then the intake will affect it directly. Note I have NO
experience with Suzuki bikes.
