Hey guys, does anybody have any experience with them exhaust valves and when they don't work what happens? I have tried searching and haven't come up with much. does the sled ever cut out/fall on its face after starting a pull? I had that happen a few times. I stumbled across this video, exact sound at 3:56 https://youtu.be/C6U2KPGbmpA?t=3m50s same as the sound my sled made last ride however it still pulled rpm ~8k or so, probably due to the turbo helping it. I also noticed my air fuel fluctuated oddly between 12:1-15 ish really fast while the bog/stutter happened.
I have checked my valves and the diaphragm and the ports, all is clean and no blockages/ issues I can see.
any way to test the solenoid that controls the valves? when the sled is off should the solenoid be closed off or open? Do they stick? I read on the older 900cfi sled some guys were drilling out that small hole under the diaphragm. (although mines not plugged but while im at it?)
Thanks!
