depends on if your on a 600 or 1200, the 12 should come up pretty easily regardless, the 6 is a little trickier, one down in the front may do it...but whatever you do, if your looking to do wheelies, youll wanna go UP in the rear, not down.....also a piece of advice...on a B6, powering a 6 up on throttle is next to impossible, but heres a couple of little tricks to it
1 is you can clutch it up, by bringing your rpm's up in 1st gear the dumping your clutch you can bring it up, but be careful, too much rpm and youll be laying flat on your back, start in first rolling at about 4 mph get the rpms up to about 1800 then dump the clutch, see what it does...adjust the rpm to come up smoothly, and remember your bodyweight can affect this greatly.
the other way is get the bike rolling (4-14 mph) then blip the throttle <let off the gas quickly) as soon as the forks attempt to start expanding (coming back up , they should do this fast) give it some gas, this is the way i stand mine up and it works pretty well, B6's are hard to keep up stock, you have to work on your body balance to keep it up, once its up.. the wheelie is going to depend on YOUR balance more than throttle positioning.
Above everything else remember, 12 o'clocks are something that take a lot of time, patience and nuts to pull off, don't rush it, be cautious and persistant, respect your bike or find disrespect from the asphalt.
