x2. Looks like cams will get you where you were on performance. Throw in some headwork and you'll be real happy.

It doesn't matter. No dyno is going to lie that much. let's say we have the hang around put them on the same dyno on the same day and get back to us.

it's not about the dyno lying, they are just different run conditions and different ways of measuring. to accurately compare 2 graphs they would have to be from the same dyno on the same day no? i am certainly willing to be educated tho i can't imagine anyone has that much time.....

A cam change would do wonders for the 110 as well.

Knock off about 3 & 3 from the std numbers and you can still use them for comparison. Both bikes seemed in dire need for a cam.

It was nice to see a comparison in the stock form. Thanks for posting them.

that is a fact.

The 103 is notoriously lazy in stock form, and the SE motors do considerably better with better cams.

This "hang around" only posted the thread because so many local riders have been asking for a comparision. Harley tuner I am concerned about the wavy curve as well. X Rider thank you for your comments.... To answer your question I see a big difference in throttle response between the 110 and 103.

The C/F is a unit of measure, think of it like standard and metric tools. in the U.S. S.A.E. is the unit of measure we use on the dyno. STD gives higher results, around 4% or so. The smoothing factor is usually set at 5, if the smotthing factor is 5 and you still have the choppy lines, your timing could be off. Your 103 was run in horrible conditions, so that didn't help you any either. Just remember, the dyno is just a tool, used to tune your bike. Other than that it isn't worth anything except to give a guy bar stool bragging rights. Somebody mentioned here that the 103 wouldn't do anything but look at the 110's taillights. Depends, if the 110 was in an Ultra and the 103 was in a dyna i'd beg to differ.

Anyways, welcome to the forums. I remember when my status was "hang around", heck, everybody here was hang around once to, right?
