Throttle blade whistle on a promax/ laser injected motor?

[silverbullet02]

I've heard throttle blade whistles on 260s and 225x motors with the one big throttle blade, but haven't heard it on a laser motor before. I got my injectors cleaned and went out for the first time tonight and she was whistling under part throttle and at idle. I pulled the cowl and started it up and it was whistling, and before I had a chance to turn the idle ajustment on the upper throttle blades it quit. It whistled once or twice more and that was it. Took a look when I got home and didn't see anything obvious. I'll look at it this weekend, but has anybody heard one of these motors whistle before?

My old pro max did it at idle sometimes. Never figured out why.

That means your motor is sealed up good and has good vacuum pressure if you have access to a ddt check it out your motor should hit like an animal now
