2017 GSX-R1K S2B: Episode 4 - Exhaust Installation and Theory (Part 2) Standard vs. 'R' Version - Brock continues the discussion on OEM exhaust systems and their function and analyzes restrictions as well as potential cures. He enlists the help of 650ib’s buddy, Luke, slip-on clad GSX-R1000 ‘R’ to help answer some of the questions posted in Part 1 as well as putting to bed the question, “Is the R version more powerful than the standard version?” Once again, he gets down and dirty to make the discussion as fun and enjoyable as possible. 2017 GSX-R1K S2B: Episode 1 - Parts Introduction & Overview:    • 2017 GSX-R1000 S2B: Episode 1 - Parts Intr...   2017 GSX-R1K S2B: Episode 2 - Initial Dyno Break-In with Chart:    • 2017 GSX-R1000 S2B: Episode 2 -  Initial D...   2017 GSX-R1K S2B: Episode 3 - Throttle Blade Derestriction:    • 2017 GSX-R1000 S2B: Episode 3 - Throttle B...   2017 GSX-R1000 Stock to Brock - SPECIAL EDITION (Q&A) from Episode 3 :    • 2017 GSX-R1000 S2B: SPECIAL EDITION (Q&A) ...   2017 GSX-R1K S2B: Episode 4 - Exhaust Installation and Theory (Part 1):    • 2017 GSX-R1000 S2B: Episode 4 - Exhaust In...   The details : Brock’s Performance 2017 GSX-R1000L7 Standard model (not the ‘R’ version) Traction control – Motion Track Traction Control Standard (TC=OFF during testing) Suzuki Drive Mode Selector (S-DMS) Power Mode=A (max power selected during testing) Fuel used during test: Shell 89 Octane (choices available at our local Shell are 87, 89, 93 octane – we selected mid-grade for our tests) Rear tire: Stock Bridgestone Battlax RS10 190/55/ZR17 – 35 PSI Nitrogen Motor oil: As delivered (unknown) Air filter: OEM PAIR: Blocked Power Commander: On bike with ZERO map installed (equivalent to no Power Commander at all) ECU: Stock 5th gear pulls Luke’s (GixxerGuy’s) 2017 GSX-R1000R Traction control – Motion Track Traction Control Standard (TC=OFF during testing) Suzuki Drive Mode Selector (S-DMS) Power Mode=A (max power selected during testing) Fuel used during test: Premium from Sheetz Convenience Store (Akron, OH area) Rear tire: Stock Bridgestone Battlax RS10 190/55/ZR17 – 35 PSI Nitrogen Motor oil: Suzuki ECSTAR 10W40 Air filter: OEM PAIR: Blocked Power Commander: None ECU: Stock 5th Gear Pulls Dynojet Model 250I dyno using DynoWare RT and WinPep 8 dyno control - displaying the SAE scale (unless noted otherwise in video) Video Introduction – Thanks to our GOOD BUDDY, 650Ib, and our new friend, Luke (GixxerGuy,) we have a 2017 GSX-R1000R with a beautiful Yosh slip-on exhaust to test/compare to our standard version 2017 Gixxer. Let’s find out WHICH ONE IS FASTER!! 2:00 Standard mode base runs (ALWAYS same time/day to test the power output for the days atmospheric conditions) 2:25 R model base runs. Quick shifter and auto blipper are incredibly smooth and seamless! 3:30 Standard vs. R model base run discussion 5:55 What did we just learn? The R model has MANY advantages over the standard… additional power just isn’t one of them  7:30 Does the damn EXUP valve actually make more low end power?! Check out this trickness we set up in Dynojet’s WinPep 8 software to help figure it out. 8:45 More base runs. We can’t get enough. 9:10 Disconnect EXUP (Suzuki SET) cables and run again 10:25 EXUP run discussion 12:40 Real time horsepower and torque tests of the EXUP valve (Suzuki SET). Is it there for low end gains or noise control? 15:50 Results discussion. WHY does the OEM exhaust work the way it does?
