1270 DYNO
This Saturday I dyno my bike with a sniffer.The last time I did was at Road America but we didnt have time to play with the injection.It has a Muzzy exh,1270,cams at105/100,+3 deg timing,k&n's.Like Cliff Randall I am hoping for 200 hp but will probably only see the mid 190's.(it was 185 at RA)Has anyone made over 200 w/the same mods?

I would be interested to see your dyno sheet on that 1270. I will be installing the same kit in ZX12Girl's bike with the same mods execpt it has an Acropovic(spelling) pipe. I think you will be hard pressed to see 200hp from what I have heard!?

Well I didnt make 200hp, but it did make 190.7hp and 105.6
ft lbs of torque.I probably should have drained the gas since it was from late November.The HD dealership wasnt set up to blow air directly into the ram-air but he said that would be good for another 5 hp or so.Has anyone ever experimented with this?

Good #! Ram air would have an affect if air was blown into the ram air. Did the tuner have a fan blowing towards the front of the bike while being dynoed?

There were two fixed fans blowing into the radiator but they were mounted low,they are a Harley/Buell dealer.I asked if they had some flex hose to direct some air towards the intake but they didnt have any.My air/fuel ratio is a straight line at 13.4:1, he said that he could richen that up for more dyno HP,but on the street it would make less HP.Any thoughts on this?

Last year the same place did a friends 12r with a pipe(Muzzy) and power commander and they ended up with 169.9 hp and 97.1 ft lbs torque.That was about 3 hours of dyno time.The final air/fuel ratio they ended up with is identical to mine at around 13.5:1.(I am using the Muzzy 1270 map)

It's funny you ask that questions, because I have asked it several times. What I was told that in drag racing you need to richen the mixture at the track to make more power. Mine makes 168.3 with a mix of 14.1. When I set it for 13.5 to 1 I make like 166.4 somewhere around that. I was trying different settings, just to see how the bike would respond. I am going to keep it at 14.1 until I reach state side. What was your hp before your modes and what did you have the a/f set to?

Sorry I cant answer that since I never dynoed it before the mods.

Semi-quote from my dyno guy...
"I can lean it out (14ish to 1) and give you more HP on paper but for real world power/speed...13.2ish is best"...
