Just put a 120R in my 2007 FLHX, Crate engine with HPI 58mm throttle body and rinehart 2 into 1 exhaust. Bike was tuned with a SE pro tuner, and on a factory pro dyno. Here are the numbers 130 HP, 123 TQ. Once I hit 1000 miles will re tune once engine loosens up.

 

new to this forum guys but have been reading it for several months, that being said and being from maine and in the 120r club up here the tuner that you speak of that has the 4 gas system is he from the augusta area? I am going to get my 2012 120r street glide tuned in the next upcoming month after mud season he uses a factory pro dyno , L.A harley uses a dynojet and they have seen a realistic 120-127 out of these 120r engines stock with supermeg and would belive them its about where it should be ,I have gone a different route because I like the look of duals I have altered mine a bit from its original form with roller rockers and 662-2 from t man along with a head mill and 0.30 head gasket. last year the power was smooth all up threw the powerband and it did't stop pulling at 6k with just a se pro tune map so who would you have dyno tune it ? 4 gas or afr tuning ,I have been working on cars for 30 years dealer trained and some harley stuff, seems to me that if cars meet emmissions standards by tuning with afr and o2 sensors then 4 gas might be a little on the overkill side with different camshaft profiles as wild as the 266 is ,or t mans 662-2 or 3
by the way the dealer that I speak of did not sell me the engine or any parts to promote inflated numbers

 

If it is different dealers/dynos numbers don't mean ****. 1 can say 150 and 1 can say 130. The 130 may beat the 150 in a race. What matters is the 2 bikes done on the same dyno under the same conditions. 85 degrees, 1000 feet below/above sea level etc.

 

Well not to pee in any pudding did you ever run a bike with 150 to the rear wheel you best be hangin on and as for the 130 beating the 150 any thing is poss. But same type of rider torque wins the race ask any of the top dogs out there.JMHO.

 

Just had mine dynoed at the dealer 124hp 119trq. Other than the valve train noise (The nature of the beast) I couldnt be happier

 

2013 RG, 120R, 1100 miles, Screamin Eagle AC, D&D Borzilla, PCV, Dynoed By SPP, at Rossmeyers
Biketoberfest 2013. 128 squared @ 5500 on a dynojet.

 

You might as well go with an S&S 124 .................585 cam

 

I was talking to Jason, and Jamie. They were going to do some research as to a comparable cam to what I have in a gear drive. Looking at the upgrade in the spring at Daytona again. Brooklyn B. What do you see as the advantage with the cam you mention? Have you seen it done? If so any numbers?

 

totally agree - for the same price with a warranty

 

Any updates to this thread?? New exhaust options etc? New numbers???

What will a street-able 120R do??

120/120 or 130/130??
