I have a whistle that comes from i think the exhaust. I only hear the whistle sound when i go above 60% throttle. It will happen at any speed as long as i give it enough throttle. The 150cc has 900 miles on it and is a 2009. It runs in top shape I am just curious as to what this whistle sound could be coming from? I dont see any visible cracks in the exhaust. Please help.

Refer back to your original post, please. A forum member has already suggested a starting point:

If it's exhaust, it could leak from a crack or a gasket. If it was a gasket, you'd probably get a small pop on deceleration (backfire). If the pipe is cracked, make the acquaintance of someone who welds; a new pipe could be expensive.

Start with the intake, as recommended. If an intake boot or manifold is loose, air can get sucked in where it shouldn't be sucked in and whistle too.

I'm going to lock this thread to ensure all replies stay with the original thread. If you must "bump" a thread, simply comment in the original thread, Starting a new thread doesn't bump the original thread, and creates confusion. The link to the original thread is in the comment above. Thanks!
