Hey everybody im new here to the forum and I recently bought a ROMA HORNET 150CC motorcycle from Supersportz.com....Its a 2011 scooter but had the frame and body of a motorcyle.
My question is: When riding around 40mph and I release the throttle to slow down, the engine makes a metal on metal rubbing noise as if something is loose right below my crotch area and right above my fee where the pegs are at. I can feel the rattle and vibration on my feet thru the pegs but it just seems to lead to the engine. I tried checking for any loose parts or metal scrapping but couldnt find any. Any help??

Check the motor mounts they may have left out a bushing.

Another thing to consider is the centerstand. There is supposed to be a little rubber wheel on it that lets the engine move forward and back as the suspension works. Those often fall off and then it'll rattle just like you described. Rich

So does anyone think this might be an internal engine problem ? like inside the motor itself?

I think this is a normal Leike Hornet noise, mine has made it for over 1000 miles and no problems so far.

Check your vacuum line to the de-accelerator (ACV) on the carb... it could be burning VERY lean when you let off on the throttle...

Good call Sprocket, I thought he was referring to the rattle it makes accelerating. Guess I need my glasses. Definitely check the vacuum line to the decel, if you didn't replace it during PDI it will rot within 2 weeks.

Thanks for the tip Sprocket, but yea (no you dont need your glasses my motobravo friend) cuz it does it when I accelerate and de-accelerate....I figured if i ride it more a little harder it will either break or go away, lol.....its so annoying, i got a 6 month warranty on it, and its barely been a month.....so hopefully supersportz.com will replace it or figure out the problemo. But the rattle sound seemed to get a little more worse, as in more vibration and shaky around my feet thru the pegs...
Also a buddy of mind recommended that I ride the bike and maybe hit the kill switch or turn it off while im riding and cruz it to see if the noise is still persistant or only happens when the bike is on....he said this would determine if it is an internal problem or external/frame problem....

Good call from your buddy.. sounds to me like engine mounts as Alley mentioned.. check your bolts there too.. they could be loose...
Heck .. I spent two months looking for a weird rattle and finally found it was the foot peg on the kick starter!!!
It only did it between 35 and 37 mph...
