POWERHOUSE has them in stock, we always do. We sell the ones made by RCC. The ones sold by Orient are junk.

Sometimes it happens backfire, and the withdrawal of gas, the butterflies are bent!
Do you use stainless steel butterflies and whether you have similar problems?

Thanks

Stainless steel throttle plates are used as replacements when the stock plates become damaged - usually from a lean misfire.

Yes, I noticed in the log data to the mixture before the poor (about AFR = 14:1)
I repaired the fuel map, the AFR is now about 11.5: 1 (on the pressure).

If you install both cables and adjust them properly - with the correct freeplay - there will be no "stiffness" in the feel of the throttle. What are you attempting - having one cable to open the blades - is dangerous, especially with a turbo. When the bike is up on boost you run the risk of those blades staying wide open . . .

Are your throttle plates bending in - towards the motor - or out - away from the motor?

Are you closing the throttle after a boosted run? Do you have a blow off valve (working properly!) on this bike?
Are the blades bending IN or are they bending OUT -away from the motor?

 

[busabiker888888]

It happens when on boost,the blades bending out from the engine.Blow off valve working fine.

You are at full throttle at around 7500 rpm, A/F at 11.8:1 when this happens? What is your boost level, what octane fuel are you running, and how much timing do you have pulled?
