1 st off welcome to the forums!! We hope you enjoy it.

2nd, going from your "Little" amount of info you have given I felt this problem had nothing to do with the thread you posted it in. So I seperated it into it's own thread. This should help you get input from other members.

I do want to give you credit for using the search feature of the forums to find the thread you had posted it in. Too bad everyone don't use it!!

Now too the problem: The noise you hear is while giving it gas? With the limited info given this: To me this sounds like a air leak in either the exhaust or intake assembly.

More info will better help finding the problem. Where does the noise sound like it's coming from? Front? back?, right side?, left side? Internal? ect. Did it start making the noise suddenly? or slowly over time?
More questions may get ask and may be needed to find the problem.
Thanks
Howdy

it starts when you give it gas getting on it hard.it sounds like its coming out the end of the exhaust.it dont do it when you drive it around in 1st or 2 gear only when you romp on it.it sounds like a whistling sound coming out of the exhaust.and when you just let it idle you can rev it up and it dont do it then either.thanks for the welcome also.

I would look for a hole / leak in the exhaust. Probably near the front of the muffler or at the connection to the head pipe.

Could either be a rusty exhaust pipe, or maybe a leaky air filter, but I'm leaning more toward what Howdy said, probably an exhaust leak. It's not abnormally loud, is it?

really its a very quite bike.

That's one of those rare hondaline options... It's a game whistle to keep wildlife off the trails so you don't hit them.

sorry... I couldn't resist!

to the forums! post up some pics of your ride!

I had a problem like that with my 250sx,it was the headpipe,it's a double wall tube and the inner tube was broke and sound like a timming chain noise.Maybe this can help.

so in all it shouldnt hurt anything then.
