it's kinda frustrating to have a 750 that is slower then an average 350, trust me i know the feeling and like someone else indicated, i'm amazed that you were able to hit 105. Honda really screwed the pooch with the 2nd generation VT750's, the original shadow 750 was barely adequate with 70hp and it was considerably lighter, the 2nd gen shadow 750's at 600lbs and only 45hp are total gutless pigs and sadly as amazing as this sounds, there seems to be 0 aftermarket performance parts available for the vt750's. there is an older post in the forum where somebody switch out the cams with cams from a certain 650 which he claimed really livened up his vt750 performance but for me the post lacks some critical details to make me comfortable about attempting the switch. the things i have done to make my VT750 at least safe for highway riding is opened up both the intake and exhaust so they flow more air and switched my gearing to 18/38 however. in order to install an 18 tooth counter sprocket you have to make a few modifications but for me it has been well worth it. the 38T rear sprocket you can get anywhere online but these are the mods needed and and a link for the 18T gear:
first the teeth on the PBI 18T need to be cut from their pointed 10.5 mm height down to match the non-pointed 7 mm height of the stock 17T counter sprocket and secondly the shifter shaft still has to be notched by a few mm for the sprocket to clear. The whole job took me only a few hours to do and that was with me going extra slow while figuring out what all needed to be done.
