Figured out why the carb just dumped fuel like it did. Someone put the fuel supply line on the vent nipple! lol.

That's how the morini intake is smack dab in the middle of the engine bar,it makes you wanna not even screw with it cause of its location,wonder its possible to run one of those stage 6 r/t engine mounts that leave the middle open so a better designed intake can be made or bought??  |

Make your own when it comes to these unless one is specific to your bike. Scootertuning has one of these in the Zuma section and it does not fit the Zuma. It will fit the motor, but has to be altered to fit the frame. |

I've been doing some work on the exhaust today so I figured I'd see how a mina exhaust fits up on this Rattler engine...  Pretty darn close fit and very doable! Here's the flange that needs to be rotated...  Here's a few exhausts laid side-by-side. Top is Minarelli, middle is TGB , and bottom is Rattler...  They all have different flange angles...  The TGB exhaust isn't a close fit at all but still doable with cutting and welding...  Back to the Rattler exhaust- I cleaned the pair stuff off the engine and now to remove it from the exhaust as well...  Cut, cut, grind, grind, weld, weld...  This scoot is missing the heat shield for the exhaust and I thought it'd look kinda bare without it so I dug out an old one meant for an Adly exhaust and started re-situating the mounts to fit it...  More cutting and grinding and welding and painting and here's the final product. Reminds me of a Zuma 125 exhaust!  |

I thought I'd be out test riding this scoot today but unfortunately I've hit a wall... After getting the engine cleaned up and mounted back in I tried and tried to get it started- the good news is I've had great luck with adding water to the cells and bringing these "dead" scoot batteries back to life. Saved another one!- only to find it's not getting fuel and would only fire with a spritz of carb cleaner. I tracked the issue down to a bad float in the carb- a really bad float. Check this out!  Lol. I'm assuming whomever did this is the same guy who put the fuel line on the vent tube haha. A for effort anyways! I tried and tried to repair it with solder but the metal-whatever it is- refuses to be soldered. It also seems that these stock 16mm carbs w/flange on these Rattlers are hard to come by and the few who are selling "Rattler 110cc carbs" are asking $100+! Shoot the best price I could find just to replace the float was $40+... So I finally tracked down a 19mm carb (which should be a nice little improvement over the stock 16mm btw) with the correct flange (42mm center to center bolt holes) on ebay. Most sold have the 48mm bolt holes but it seems the Dio's/Sym's/Kymco's use the same flange so I picked up this ebay cheapy for 26 bux shipped. Should be here Thurs...  Take THAT Rattler carb sellers!! |

That is one fine hack job they did on the float! LoL! I have a couple Kymco carbs laying around, dont know the size but let me know if you end up needing one. Do this flip up nice, I may have to make a trip to FL.  |

I ended up using heli-coils to fix mine. The only place I found pilot jets for this were from jetsrus. Main Jets / Pilot/slow jets The only running issue I have with mine is when the engine is cold it stalls unless I peg the throttle to wide open. One warmed up it runs fine. I'm sure its probably jetting(low), but I am looking for do a different intake/carb setup for this scoot. One more note, its advertised as a 19mm(outlet end) but Iv measured the inside and it averages out to be about a 16mm(opening in is an oval) |

It sounds like I'm getting the exact same thing that's on there then- 16mm. I thought it looked exactly the same- probably is. Well I guess in that case I can just use the float to repair the stock carb and keep this cheapy for parts... |

Some parts getting their satin black treatment...  I've been thinking about changing this Rattler from silver/black to all flat black. I've seen a few of the flat black Roughhouses and Rattlers and I think it looks badass! Hmm. Decisions decisions. I'm also considering doing it in flat black plasti-dip so that it could just be simply peeled off and not necessarily so permanent- although there are a few pretty deep scratches on the front silver panel that I think I'd like to at least fill a little with primer and sand. Now that I look at it more closely they're actually deep enough that could probably use some bondo filler. Crap. I don't think I have I have any leftover bondo so I'd have to go buy some. Oh well- something I should have in my garage anyway...  |

Id would do a bit of tuning to fix the problem, but I just can't justify buying a few pilot jets for it when my goal is to get a true 19mm carb. |

Hey hey carb came a day early! Wow that was fast! Time to go leave some positive feedb.... wait wha?- this carb seems awfully small for a 19mm... shoot, this aint even close to 19mm! Sure, the i.d. of the flange measures 19mm but the throat/venturi of the carb actually squeezes down to a mere 11mm x 13mm oval. Dang. The stock carb on this Rattler- which has been called a choke point on this engine elsewhere on the web- is actually a bit larger having an oval throat that measures about 12mm x 17mm. Still not quite 19mm, but much better. Here's a shot of the two carbs side-by-side. Stock Rattler carb on the left. Cheapy Ebay "19mm" carb on the right...  Luckily, the main thing I needed- the float- is identical so I swapped it into the Rattler carb and installed it in the scoot. Regarding the Ebay seller; I won't leave negative feedback, I'll still leave positive feedback considering the shipping was lightning fast and they probably have no idea about these carbs anyway. They probably just go by the description that the Chinese suppliers label these with. Dang you China parts suppliers! Duped us Yankees again!  So with all the carb mumbo jumbo out of the way- the good news is we have a running scoot now! 2 stroke smoke!  I couldn't help myself and threw the front fairing back on with the headlight and strapped the battery to the frame and went for a ride. I took it easy for the first couple hundred yards haha. After that I goosed it and oh yeah this baby wants to buck you right off the back! When I was turning around I goosed it again and it shot me about 3 feet in the wrong direction as the front tire came off the ground during the turn. True to rumor the Rattler will wheelie! I didn't get into it super hard as it was just a short little test ride but the speed seemed pretty decent. I'd guess I probably got it up to about 50 or so just through my neighborhood. Dang I'd really like to see what this engine is capable of all uncorked. From what little info there is about this scoot on the web, the general consensus is that it's really bottlenecked up to meet stringent EPA requirements... Oh yes, I have been taking some measurements and specs as I go along. I checked and double checked the mounting system and it's a match to a Minarelli. Direct Swap Capable! Here's some of the other specs I've gathered. Besides the typical manufacturers specs that are available for this bike, detailed info seems real hard to come by on the interwebs.  |

Way cool that she's running! I'd like to take one of those 90/110's for a ride one of these days and see what all the hype's about.
