120R realistic hp/tq numbers
#12
If you want realistic dyno numbers then run it on a dyno that actually gives real numbers. You put it on a "happy" Dynojet and you'll get "happy" numbers. Will that make you feel good? I don't know.
Personally, I'd rather know what the motor is really making and tune for best power across the RPM range. I just had my 107 tuned on a Factory Pro dyno and it made 97hp/107tq. Do I feel good about that? Damn right. The bike runs great and has tons of power. Would I have been happier if I went to a Dynojet and got a lesser tune but numbers in the 112hp/123tq range? No.
If you can wait a few weeks we're putting a 120r in my buddies 2010 Dyna right now. It will get tuned on a Factory Pro dyno in a few weeks and I'll give you the real numbers.

Yes, I totally agree with you. Sorry missed where you said you dyno'ed on a Factory Pro. Went back and still don't see it... but doesn't matter. I was going to go as far as to say a similar 120R build (TB, pipes, intake, injectors, etc.) on a similar bike with riders of equal capability - The 120R tuned to 120 hp/tq on the Factory Pro will spank the crap out of one tuned on a "happy" Dynojet to an inflated 135 hp/tq under all real world conditions: ridability, roll on acceleration, 1/4 mile. Take your pick.
I'll be damn happy if this 120R motor cracks 120 real hp/tq. The guy who tuned my 107 said that pretty much ALL 106's (107 is really 106.6ci) make between 103 and 106 lb/ft of torque. Cam choice can get you more hp. He should know as he's tuned plenty of them. But if tuner A gets you 106 lb/ft and tuner B with his "happy" Dynojet says he got you 125 lb/ft... and you don't know any better... who would you think is the better tuner? There are some guys out there using some pretty stupid correction factors on DJ's.
Edit: Duh... should have seen you're from Maine. I think we have the same tuner. ;-)

My Stock 120r made 134 uncorrected hp. Fuel mileage adveraged 38 in touring mode.That was tuned at jd's cycle works in Penn. I have since changed the cams to the tman 662-1 cams. I can tell you already with just a vtune on the street its making more torque. I will be posting numbers when I get It dyno tuned.
I can also tell you mine does get very hot when in traffic. I do have a hd oil cooler on it.

I will be keeping an eye out for those numbers.
Hey, is it true that the 120R doesnt have roller rockers?
