Dylan Rithamel says:

Alright so this all worked almost perfect the first 3 gears are good but i feel like 4th and 5th gear dont have the full power like before and wnt rev really high, is this because i need to re adjust the throttle or should i try to resolder it or what do you think? I felt like when i changed into higher gears it would rev all the way high for a second an then wouldnt go past 11rpm. I got it to 140 mph but not 160mph like i normally can. Its like theres not alot of power in the higher gears

2008 Suzuki Bergman 400 code 28. You want to fix mines ? Anyone ?

Kenneth Ford says:

James, the circuit board went bad on mine. No resistance. I ended up running solder wire externally. Runs better not using motherboard. I have 7.8ohms resistance at each pair of connectors.

Nice vid bro, very helpful!

Rehan Sardar says:

Dear James,
I recently subscribed to yr channel and find your videos extremely helpful. I own a Suzuki boulevard M50 which also employs STVA. Can you pls advise if this component on the throttle body is also responsible for controlling the idle speed since the throttle body on the boulevard does not seem to hv a separate idle speed control valve like most cars or some bikes also hv. I ask because someone I know is having erratic idle speed issues. Already told him to check the TPS, STVA and vaccum lines. Many thanks.

Just remove the butterflies. Doesn’t hurt anything. Just a little more low end torque

Vistian says:

Thank you James

Robert Sanchez says:

What's up bro. Hope all is well. I have the same exact problem, but what happened is I live on a hill, it rained pretty heavy last week, and the water filled the bottom part of my bike cover and the weight of the water took my bike out. So basically my bike was sitting in water for a few minutes until I picked it up. Yesterday I rode to work, and noticed the c28 code. I took the stva off and shook it and water came out of it. It's the same one in your video. But my bike is a 2016 gsxs1000. Should I open it as you did and check the parts inside, to see if the water messed it up? Im gonna check the butterflies too, but if they're not functioning properly, could it be the stva or you think it might be a different problem?

Austin Nonya says:

Bad ass tutorial dude. I have mine torn apart. Nothing looks burnt or broken but I’m going to resolder it anyways and see if that takes care of it.

Myles Bennett Dyson says:

2002 gsxr 600 the same procedure?
