Let's see the sheet. Your TRQ and HP both peak at 4970 RPM? That's odd. Normally the HP will carry on closer to the rev limit. What kind of compression are you running?

Jerry from Dynotunes Said same thing when he had it on the dyno, He said he has seen some strange things happen when he has bikes dial out over 130hp..First pull only kicked out 121hp 132tq, But noticed back wheel was slippin on the roller, So he had to strap bottom of crashbars down .Compression ratio 10.5 :1..

Those are serious numbers! But they may not be peak, perhaps the engine was only revved to 4970rpm. It is possible they will get even bigger at higher rpm.....

146 Rwhp @ 4950rpm and 10.5:1 ratio?
I couldn't believe it myself until I looked up the specs.
I guess it's possible since 85ci (1400cc) motors are at the 180rwhp mark now. But that's at higher revs, 4 valves per cyl, and higher compression ratios.
