I am thinking about more power for my springer. Has anyone got any constructive feedback about the 120r motor? would my current bolt ons be reused if I purchase a 120r? How much will it cost me for the motor supplied?

Any info would be helpful.  Cheers

 

The 120R needs a fair bit more compression to work well with the cam it comes with. The 120ST would be the better donk to start with, or even the S&S 124 engine. Seeing as you already have a 113, which use same barrels as the 120, you could re-use your existing parts, & just add the 120 crank & pistons. - Rob

Correctly set up you should have around 120/120 now.
You will get around 125-130 with a crate 120r.
Cost will be around $8-10k installed and tuned .... is it worth it ?

would not make for a good touring , only short distance work , need a oil cooler etc ,i raced a 120R for Frasers Sydney  that i ported Polished & set up da Comp Ratio etc , Dyna W/Glide  stock tyres etc no wheelie bars  street trim 10.1 sec 1/4 E.T. @ 145 mph,  no bullshit

Thanks for the replies. Was just thinking what the next step to take was to produce more power/torque FUN!!! I was thinking if the price was right I could offload my engine minus HD clutch, throttlebody, injectors and throw these on the 120R and have myself a new motor with more potential. Not something im jumping into right away just looking towards the future.
