STVA Remove Help!

Hi All. The 3D print works! Smooth like butter. I can't upload the video here. But it exactly 100% replica to the keihin Stva... I am out of time today but definitely will try to clear the C28 by testing further...

Great find!
And good luck, hooefully that solves it.

My problematic slot became a hour glass.

By the way may I confirm that when 3.9V for the stps the butterfly plates must be 90degree to the throttle body. But for the 0.5v or full close. Which position should it be?

I meddle too much with the stva til I lost confidence. The butterfly valve spring forward to the dash board to form a 90 degree close to the throttle body. By using finger push backward close, I only manage to get about 85 deg to the throttle body.

When close the buttfly valve should move forward to the dash or backward to the brake light? Please advise.

I cannot remember, but I think the rear of the secondary plates raises up toward the back of the bike when they close?
I will check this afternoon when I get home from work, as the airbox is off my Gsx1k, and all they all work basically the same.

Hi Sixpack577,

Thank you for the help. I watch some YouTube video on the stva. They move backward to the bike and then center straight up 90 degree for full open. I guess that's correct.

OK I got too happy too early.

Was going thru something about the STVA and I realize something...

Hayabusa STVA

Gsxr 1k Stva

Notice the slot angel and the depth are a few mm different...

I will bring the original for a 3D scan then repair. Wasted the time.

In the post the 1k guy did mention he purposely tune 5 degree of because of the limit of very easy get C28. I will try to tune again to confirm the setting on the gear.

 

[Dafeimao85]

I think will print 2 wheels to confirm I dunno which degree should the slot be like

Wish me luck...

It's official.

Like what Sixpack577 said.

Alot of parts looks the same but not interchangeable.

The 1st 3d print fail.

Will be sending mine to scan
