Thanks again for the info. I think I'll keep it the way it is for now.:thumbsup:

Thanks. I see what your saying. What about an air fliter? What one works now?:banghead:

If cutting the airbox to the size of the air filter is the small airbox mod than whats the large airbox mod? Can any one give me some clarity on the subject? Maybe some pics? ???

Thanks for the info. One other thing my bike is mapped ,would the map need to be tweeked with all 4 short stacks. I was told that each cylinder has been mapped.

Got a '06 Busa looking for info on Factory Pro velocity stacks and their ignition advancer. Has anyone done these mods. If so what do you think, are they worth doing?

What do you think about it jumping a tooth in cam timing?

I changed the plugs about 5 months ago w/ngk ir's. I own a body shop, thats where the bike is keeped so I clean the filter alot. When I got the bike back the first time it was awesome ,it pulled hard. Again we switched bikes and he felt it was faster, he was clutching wheeles in 3rd.

I rode with friends '07 busa stock and his will walk away form mine.I've got about 80lbs. pn him so we switched and the same result .

It was done at Joe's cycle in Mechanicville,NY.He has already ruled out loss of map,compression loss,fuel management.

Both figures were done on the same dyno. The shop where the work was done has a wall with dyno figures with similar mods ranging from 168 to 175 whp.

I've got an '06 busa with a tre, fullsystem, large air box mod, bmc race filter and a custom map.Dynoed at 171.5 whp and 101.3 ft-lbs. Now for seemingly no reason it is down 20+ hp, but still runs smooth. Does any one have any ideas of what could be wrong?
