also remember that the 5K motor will need intake, throttle body, injectors, race clutch, clutch plates, tuner, exhaust, gaskets, fluids. still a good deal if you install yourself and sell your 103

 

RC Component wheels carry a 7 year chrome warranty.

120R man!! it does add up fast, for best power, you really need a big pipe like the D&D Borezilla or something similar, about 500.00 for the TB/injectors/ACR harness and a tuner, please, please dont use the factory stage whatever map, good tune from a really good HD shop better yet a independent that knows his/her stuff. Im in the process of doing a 120R plus build, Tman cams (662-1), roller rockers, head work, HPI 62mm TB. Shooting for high 140's hp/tq. Out of the box, these motors are wicked. There are a few threads over on some other boards detailing our build. Motors are tight and appear to be very well put together (from what we have seen after taking them apart)
Oh, dont forget to add in a clutch, stock WILL NOT hold the power the motor puts out
Check out V-Twinforum for more 120R details (under twin cam engine mods)
There are a few dealer selling these motors at 20%, pm me if you need any more info.

 

Just my $.02. If your already close to them sounds like it would take little to keep up with them. 3G's on wheels, 2G's left over for engine mods. I'd bet you'd be right there.

 

Wheelies look better than wheels, go for the power!

 

if you have the need for speed...then you already know the choice

 

Whitedogg the guy at the dealer said unbolt and bolt new one throttle body spacer and that was it clutch stuff starts getting a whole lot more than just the 5gs

 

I tried but cant seem to get my eyes off of the avatar pic.

 

WHAT ELSE MIGHT YOU HAVE TO DO WITH THE BIGGER ENGINE is your clutch and tranny heavy enaugh to with stand the xtra hp you possibly could get close to the same hp with your 103 for less $ just my 2 cents worth keep the change i dont like pennys

 

the 120 puts out 135 hp. you would have to throw mega bucks at a 103 to get over 125hp. dollar for horsepower the 120 cant be beat. tranny is fine, pick one of many race clutches
