Unfortunately Builder, I've already done that here...it won't change his opinion.
I took both of our bikes at the time to DuneToyz in Muskogee, Oklahoma and before thst, to HRI PowerSports in Texarkana,Tx.
Results: 4mm serval (box stock) 74-75hp after tune st HRI. I then boxed it up and sent it to Redline. He dynod it and came up with 73-74hp. Then he called me back (because I didn't tell him what it made before sending it to him) wondering why it didn't make the purported 80hp they were supposed to. He was somewhat relieved that I too only got 74ish hp. After porting he got it to 90hp and sent it back.
Fast forward to a season later and I have the same serval and now a 10cub. We want to tune everything before the HQ ride and go to DuneToyz in Muskogee. Brently dynos the serval and gets,,,guess what? 90hp.. surprise! The dynos were within 1/4-1/2 hp. Brently even said there was more in it but we left it on the safer side. Actually quite rich. Brently mentioned how impressive the TQ&HP curves were on the motor,but there was obviously more left.
So here's the cliff notes:
Anyone who THINKS they know what's up with Cams dyno,is FOS.
I've INDEPENDENTLY checked it ( without knowing I was) before AND after cylinders have been modded.
Cold, hard, data. Not assumptions, not looking at pictures on the internet,not hearsay,, hard data .
