When you pulled the exhaust servo flap doo hickey did it require the ECM be re-tuned ? Some how I got the idea that it would run lean and possibly burn valves .. yes ... no ? This is my first fuel injected bike. I can tune a normally aspirated engine but this is over my head. The ECM tool (looks like a cell phone) is like $600. I’d have to read the manual from cover to cover just to turn it on.For starters, my 2nd car back in the day was a 1968 GTO, so shout out to your name :-D
I got a Pure, and for exhaust, I tried a bunch of iterations with the single Pure exhaust, the double classic euro4 exhaust (fixed baffles) ,the double classic euro3 exhaust, with and without baffles.
One of the things that made it sound "healthier" was git rid of the servo flap doo hickey.
Then adjust exhausts to taste.
Gotta get the tone right.
I'm about to upgrade the rear shock, but pondering the Bilstein below.
If nothing else, it looks cool as all heck
Bilstein-RAISCH suspension strut for the BMW R nine T series. With adjustable rebound and compression damping, adjustable preload incl. height…www.classicbike-raisch.de
In 1968 I had a canary yellow Chevelle 396 with Hurst 4 linelock
almost killed myself a few times but what fun that was ! GTO’s were my biggest competition in 1/4 mile and whipped me many times.
