**** Hold on!! Stock Ambo 29VBH's come with 145 mains and 45 idle
jets. You probably only need to worry about the idle jets. The mains
only work at 3/4 throttle+. I find I rarely use more than 1/4 throttle
and that's at 4000 rpms @ 60mph in 3rd gear (mark your throttle at idle
and remark at your favorite cruising speed).
To go smaller on idle jets you're going to be looking at 42's or lower
if your's are the stock 45's
