This is the performance exhaust I installed on the Roadrunner, purchased from partsforscooters.com , It is advertised for the Retro scooters.  Before  After   And now for my review of the product and issues.  I had two problems, one was that the VIN tag of this scooter was on a welded plate, this was too close to my pipe which hit whenever I hit a bump. At the risk of cracking my engine from the impact, and scratched the heck out of my shiny metal.  I removed the tag and cut off the bracket that was welded there.  Much better. The other problem was the screws and spacers were not the correct size. The threads in the holes started in about 1/4 inch, and the bolt for the top worked, but fell out on the road, and the spacer needed to be 1/4 inch wider, and the bolts an inch longer...I still don't know what the heck those longer bolts are for  I went with 2 x 3 inch bolts I found around here, and found the right spacer at the hardware store....  I like the look much better, though I now really need to find a chrome cover for this little short case engine of mine ;D The sound, it's like a little baby harley, a nice low toned ...br, br, br, br, br br....sweet :riding: I have a different model from scrappy to try out on the baron, not enough play time yet this summer... |

Looks great Goosey! If you use long bolts through the exhaust bracket that go through the engine a 1/2 inch then you can put nuts on them with a flat washer and a split washer and they will never fall out. I don't think you need any more chrome on there. If anything maybe the floor plates and/or the metal trim pieces that go on either side of the fuel cap door would add some more pizazz but you're looking at $100 with the shipping at Scooters Georgia for four little trim pieces.  Maybe just the floor plates.   |

LOL, well I do still have the chrome air filter to try yet. Not sure yet if it'll fit. It's a uni filter that comes out on the side. Next fun day project to try. No more yearly paint job on the exhaust though  I can't tell you how many times I had those 4 trim pieces in my shopping cart and then when I saw the cost, decided not today  The other thing I didn't like about this exhaust , the lack of connectors from the exhaust to the pipe. Usually they have springs or something. My first test ride fail, nearly lost the exhaust when the bolts went down the road. I was lucky it expanded from the heat enough to hang in there. I have enough bolt coming through the top bolt to put the nut, flat and split washer on there, I'll do that before the next ride. |

Thanks for the detailed review. Nice job. The pipe looks good on there. Modifying brackets, adding spacers, replacing bolts, etc... is unfortunately the norm when dealing with exhausts for Chinese scooters from my experience so far. The only exhausts I've ever bolted up without needing modifications of some sort are stock and the one's that 190mech has built for 2Ts.

I also got to experiment with the new dremel tool The first exhaust I bought is still in the box. Just nothing about it would fit the Retro body. Too much back panel for the placement of it, and the bracket was a joke. This one was pretty easy. Though I couldn't actually use any of the spacers or bolts that came with it, LOL, at least the bracket went on nicely and matched up to the engine, and the exhaust itself fits. I have another stainless from scrappy that I'll be fitting into the Baron, that shall be #2. I also have a chrome clutch bell in the Roadrunner, and a spare CVT cover to play with, hmmm...maybe that will satisfy my shiny craving next. I should really try to get a sound clip of this thing. It makes me smile  REVEEEN: Rat bikes, nice You could so do that with Chinese scooters  We have long cold winters here, so about Feb the urge to shop for something new for the scooters hits. |

I have a good candidate here that I'm just trying to get running. Because most of the plastics are trashed it wouldn't take much for it to become a rat (or maybe it already is?).

Rat, seems all you need is some flat paint, for what you intend to use, and some creativity with the nuts bolts , clamps and whatever to rig it as road legal. Be sure to keep us all informed on your progress. Then of course I would have to ad this one shiny thing to the fender...  |

Problem with suspension? I thought it was bottoming out somewhere yet when I hit a bigger bump, but after looking it over for any scrapes, and finding nothing I noticed some minor dents in the underside of the back chrome.  It has 3.25 " between the chrome bit and the end of the exhaust, yet it hits when I go over anything like railroad tracks at a normal speed. So is it time to look at a stiffer spring? I'm not a big girl, so that 3.25 " shouldn't be a problem I'd think. I could cut away part of the chrome piece, but I don't like the idea, and if you guys think the suspension should have more to it I'll go that way. |

I think it might be time for a new shock. That seems like a lot of movement for the average rider or light rider. The adjustable ones are nice and sometimes you can catch a good deal on eBay. Measure the shock from center to center, eye to eye. Usually I get more results searching for the mm length I need.

Maybe a slightly longer one.

13.8" probably wouldn't be too much. It shoudl work OK, it's more of a taste thing if it'll bug you to be .8" higher in the rear of the scoot. The bright side to a little longer rear shock is that it puts a little more load on the front which tends to help handling.

If I go too long I'm thinking it may be too tite within the frame, and the spot where the pipe was hitting will be too close? So I need to find something the right size that can be adjusted for proper tension? Argh, no time to take it apart today, have to go to work  |

I went with 2 x 3 inch bolts I found around here, and found the right spacer at the hardware store....
Maybe just the floor plates.
