Dyno despite my starter woes
My bike is stock accept for stage one and a S&S 510 gear driven cam. My numbers after stage one were 72.5 horse power and 83.5 ft-lbs of torque. After the cam install I never got the bike dynoed. I also went from Samson slip ons to supertrapps just the other day so I thought I would dial things in.
New numbers are 83.14 hp and 86.22 ft-lbs - not bad for a bike with almost 45K on it.... or what do you guys say???
Here is the graph

The only thing I am not sxure about is why there is a rich condition (see the air/fuel mix) at around or btwn 2700-2800 rpm.....?

That's not a rich condition, it's lean between 2500 and 3100, but it looks to me like that was caused by rolling back on the throttle, because usually when it goes lean without a throttle rollback the HP or Torque will make a small momentary climb then settle out.

RE: Dyno despite my starter woes
JohnK/Pa you are correct - when I looked at again I saw that it was lean. I went back to the guy and asked. He said since my bike is carburated that I would get that glitch at those rpms .... not so sure about that, but I saw a similar bump in a previous run when I frist got the bike and changed to stage 1. Otherwise the run looks very good to me steep rises in both torque and hp and they maintain, also the air fuel seems fairly flat other than the one bump I asked about. These numbers are with diffferent pipes and the S&S 510 cams. I took a long ride today and have to say the bike is running very nice. I almost do not believe the numbers... but like I said I like how the bike runs so I guess it really does not matter..
