I have a Malaguti Phantom F12 with a 70cc Athena cylinder kit already in pace. I replaced the stock exhaust with (what I thought) a good performance exhaust, and i purchased this one: www.cbxmanmotorcycles.com/Leovince-Sp3-Gas-Scooter-Exhaust-Malaguti-F-12-Phantom-Lc-Air-98-06.aspxNow - I just chatted with some guy at scootertronics.com, and he claimed that I most likely got the SP3 model that's for 50cc - and therefore in effect is "choking" the Athena kit. He instead said I should get something that is made for 70cc kits - like this one: www.scootertronics.com/hipetwostex.html... and that that pipe will make a world of difference in my acceleration. What's your people's take on this? Is he correct? Would it be worth it to replace the SP3? |

Plenty of people use the SP3 on 70cc scooters. No, it's not the best performance exhaust out there... but I don't think it's choking your scooter and needs to be replaced either.

Ok so the scootertronics guy maybe just was trying to push for a sale then? In your opinion - would upgrading to a better performance exhaust make a big difference? The main reason I got the SP3 was that it was supposed to be quieter than the others. But it's loud as hell anyways - so I might as well have a loud exhasut with better performance? Or should I focus on upgrading the clutch and variator first? |

You have a decent exhaust already, so I'd probably move to the transmission for now. Maybe you could lighten the stock clutch or just add stiffer springs before completely replacing it. You can pick up some rollers and contra springs pretty cheap too. If you wanna go with a whole new variator for a little more acceleration, you can get a decent one for $50 or less.

Cool... thanks for the tips. So when you say "transmission" - clutch and variator is included in that term, yes? Is clutch + variator = Transmission? Would this variator be a good replacement? How can one know if it's going to fit? www.scootertronics.com/schipeva16ve.htmlGood clutch? www.scootertronics.com/prclve.htmlSorry for the cluelessness! |

When I refer to the transmission, I mean the entire CVT... variator and it's components that make up the front pulley as well as the clutch, clutch bell, torque driver and their components that make up the rear pulley. That also includes the drive belt, springs, rollers, etc...
2strokd has that clutch and bell. Instead of paying $129 plus shipping from scootertronics, you might wanna get on eBay and get the clutch, clutch bell, variator kit, and rollers for $132 shipped.
Before you order anything though, you need to know what size variator you need. Minarelli engins have 13 and 16mm splined versions. You'd need to measure the diameter of the splines on the crankshaft where the variator slides on to see which you have.

Oh wow - I wouldn't know where to begin to figure out how to measure that  I'll do some Googling - hopefully it's specified somewhere what my model has. Thanks for all the thoughts and suggestions - this is SOOOO great! |

It should fit. Clutches and clutch bells do come in different sizes, such as 105mm, 107mm, and 112mm... but as long as you don't mix and match say a 105mm clutch with a 112mm bell, the splines etc... should be fine from one minarelli engine to the next. I did have to put a washer behind my Stage 6 107mm bell to make it fit properly when I replaced the stock 112mm clutch and bell, otherwise it was fine.

And buying that clutch & bell and installing it will increase performance, just by installing it, right? No tweaks or tunings needed? |

If nothing else, your clutch should stay cooler. You might need to put stiffer springs in it, not sure what comes in there.

Yup. Even includes one set of 6 gram roller weights. I've dealt with that seller and he's surprisingly quick from Taiwan.
