Sounds crazy right... but that's what I got on this 96 blaster I just picked up... Fine if the bars are straight it has its normal power then as soon as you turn the bars it just chops it and puts it in a limp mode rev limiter. Doesn't matter if you're WOT and turn them or doing donuts holding the bars turned, it'll sit there and rev limit all day. And throttle position besides idle makes it do this, also only happens in the water. Yamahas are pretty new to me coming from my 750 X2, it all pretty much looks similar though. Maybe you guys know some problem areas with them though.. Only motor mods are Protec head and pipe.
First few things I checked was if the steering was pinching anything with the hood closed, it's not everything looks clear and nothing tight on the wires. (still suspect on the killswitch since it's the only thing related to bar movement through the wires...)
I pulled the carbs off and went through both of them, both are clean that appear to be rebuilt at some point so everything looks good there. Internal carb filters looked very clean as well.
Checked the pick up tubes in the gas tank and both ON and RES look good and I blew through them to check for air leaks, everything passed there. Check Valve works great too while I was there.
Next thing I did was open up the ebox to see if there was any obvious wire pinching. Clean ebox no obvious problems, I did remove the over temp sensor and unplugged it while I was in there as well. Haven't water tested it with the sensor deleted though. Just read that seems to be a common limp mode enabler.
My next test will be trying the temp sensor delete and then I'll be trying to disconnect the killswitch and see if it does anything.
After that I'll just be trying different electronic components.
Guess my question for you yamaha guys is, what are the common parts to put it into limp mode? We'll just pretend it does it with the bars straight too haha
