Hey All,
I have a 2021 with a couple of mods that has degraded over the last couple weeks to the point of not starting. No fault codes.
I have about an hour on the SxS, got the GYTR turbo kit and a DLP pully-style alternator kit installed, and ran it at 200ft for about 15 minutes, and it ran great! Gobs of power, just jabbing at the throttle past 5k rpms and twisting the wheel is instant brodie. Love it!
I head for the hills for 4th of July weekend, and at 5000 feet it's not running great. Unload from the trailer and as it warms up past about 140f it wont idle. Exhaust smells like unburnt gas.
Go to load it back on the trailer 4 days later and it's barely running, wont idle cold, wont throttle up, smells like a serious rolling fire hazard. Barely get it loaded up under it's own power and get back to 200ft elevation.
I assumed it was some messed up map in the GYTR ECU at elevation, but it won't even start now at 200ft. Will fire every couple of revs, and will try and catch if I pump the gas pedal as I try to start it. Oil stinks like gas too, and I'll have to change it once fixed.
Here's a video for audio of trying to start it cold/sitting for a couple days, first two cranks is no throttle, third crank is jabbing at throttle. When it does catch partially, it feels like a violent, out of time catch, shaking the whole machine and almost sounding like a gunshot/backfire. I am in an enclosed shop area, so I could be playing that part up: 2021 Yamaha YXZ1000R SS with GYTR turbo no-start
I checked the Crank Position Sensor thinking that might be it, but it checked out at 520 ohms. I double checked as many electrical connections as my hands could reach with all the turbo crap still in the way. The no-codes thing on a fancy digital, ecu controlled CARB compliant system that wont start is irritiating me more than it probably should
My only mods that could affect this are the GYTR v1 kit and the DLP alternator(side eying it, as i guess it could have a failed voltage regulator and zapped the ECU, though I'd think the primary voltage regulator on the YXZ would cover any overvoltages of an additional alternator?)
Any thoughts? I'm hoping to gather ideas before I start the process of removing all the things I just installed 15 riding minutes ago.
Thanks!
