My buddy is a MESS St Tropaz 150cc

My St Tropaz has the following problems

Whistling noise while accelerating hard ( prob cracked exaust)
Multiple backfires when decelerating
When I decelerate my buddy revs really high, it wont seem to just coast it is like having a car in 2nd gear going 50mph. It just revs high and makes a loud whining noise. Just had the oil changed and idle adjusted as well as gear oil added. Dealer said i need a new exhaust. The scooter despite all the noises performs great. I use seafoam every couple tanks.

Can't really determine what might be wrong with the scooter if you have an issue as serious as a cracked exhaust. That alone could be the cause of all the symptoms you describe.

Or it may not be. But first things first.

this is a funny post, op. are you posting just to tell us Buddy is a MESS and still runs well enough so its a Super Buddy, or are you looking for help?

seems you have a dealer around that has looked at the scoot and they say you need a new exhaust. what else do they say about the scoot and its troubles? how many miles on the 'Bud?

My buddy is a mess in terms of all of the sounds that its making! Shes a 09 and has about 1400 miles on her. Im just sayin despite all the sounds the girl runs too notch. Im mostly concerned about the deceleration not sure whats causing that! so yes i do need help lol. I dont like my dealer that much btw.

As Eric said, backfiring on deceleration is not a surprise with a broken exhaust. I would add especially before the muffler. Check the two nuts that hold the pipe to the head - they might be loose.

Take a little friendly advice here. Fix the exhaust first, really. If the noise's and other problems your having go away...Success!
If not, then let the troubleshooting begin. When you have one issue glaring you in the face, it doesn't make any sense to ignore it and expect some type of magical cure all from advice you get here. Start with the problem at hand and progress from there. And as far as the exhaust goes, it is something you can do yourself. Since you stated you don't really like your shop guy, it will save you a few bucks and give you some satisfaction at having done a good deed for you Buddy

.

also it sounds like you shop may have set your idle too high

Thanks for the help guys. I will buy a tool lot and see what I can do. The shop said they put a new exaust on and the backfiring went away. I didnt buy it however. I am most concerned about my buddys difficulty decelerating. It doesnt want to slow down when i let of the throttle. It will only coast freely when I am around 15mph

I'd say that's normal for most all CVT scoots and wouldn't worry about it. In fact I wish my BV350 would coast at about that speed. Its clutch doesn't release until about 5mph.
