Okay, so I sold my '99 Jog and opted for an ‘08 Zuma. The bigger tires, better parts availability, larger fuel tank, and hydraulic front disc brake were my main motivators, aside from the fact that the Jog was much more worn out and more of a project than I wanted at this point in my life. So I picked this guy up for $950 off of FB the other day...     It's in pretty decent shape, looks like it spent most of its life in a garage and was never derestricted, so hasn't been ridden very hard I'm assuming. It's going to need some plastic eventually because some of the tabs are broken, but I'm not too worried about that now. I probably could've found a little better deal, maybe saved $100 or so, but I wanted something quick and this was sufficient for my needs. Needless to say, I'll be derestricting it and as soon as I do, a bunch of parts will be getting slapped on. I don't even plan on riding it after derestricting it, but I did test ride it around a bit prior to buying it and it did the standard 31mph haha. I plan on making this a streetable daily driver (Michigan weather permitting) that can get up and go. Here's most of the parts I've ordered so far: - Crankshaft Polini Evolution 12mm, 80mm Conrod Minarelli Horizontal - Crankshaft Bearing Polini HQ Minarelli - Carburettor Polini CP 19mm (Cable Choke) - Choke Lever Polini Black (65cm) - Main Jet Set Polini CP 80-98 - Air Filter Adaptor Polini CP (47mm to 34mm) - Throttle Cable Adjuster Polini (90 degree) - Reed valve Stage6 VFORCE3 Minarelli Horizontal - Exhaust Yasuni R Minarelli Horizontal Black - Polini Corsa 70cc cylinder - 12mm - NGK waterproof spark plug boot - Set of gears coming soon - Other misc. odds and ends Am I missing anything? The guys at Scooter Tuning (where I bought most of it) have been super friggin cool. Had a couple hiccups with ordering and they've been more than accommodating. So I've spent way too much money already, but hopefully this turns out to be a screamin scoot. I'm sure I'll be making plenty of mistakes soon, so stay tuned! |

Sounds like a great setup. Should be a lot of fun.
What sort of variator and clutch set you going for?

Sounds like a great setup. Should be a lot of fun. What sort of variator and clutch set you going for? I’m really hoping the fun factor outweighs the frustration factor with the build lol. Never done a crank before, but I have a case splitter and installer tool on the way. As for the CVT, I already own a Polini For Race 3 clutch and Polini evolution bell, so in keeping with the theme of highly priced blue stuff, I’ll probably go with the Polini Hi-Speed variator, since I’ve heard good things. Anyone know if that’s considered over range and if I can keep my electric start with it? I may start tuning with a Hoca variator I have if I’m still waiting for gears to arrive. For the rear pulley I have this guy m.aliexpress.com/item/32829405186.html?pid=808_0000_0101&spm=a2g0n.search-amp.list.32829405186&aff_trace_key=&aff_platform=msite&m_page_id=5101amp-PnKLD1j0wpdmakUhT1VeMg1571741411027 from Aliexpress. After watching @90gtvert ‘s videos, I’m curious to try and see how a stock clutch compares as well. |

Nice part list
I like your Go big or Go home That Corsa withe the Yasuni and Gears will have you screaming at 60 plus .
Polini High Speed is a standard sport variator, you do keep the electric start it is a upgrade over stock as far as size and ramp angle .
I picked up a couple miles over stock.

Maybe I will go with an OR setup... who else makes them aside from Malossi?

Never mind, looks like there’s lots of options on ST. Anyone have any experience with any of them? So pricey... what makes them worth it?

They mostly make it easy to bypass the low end robbing pipes we put on scoots.

i can attest for the malossi overrange i wont buy anything else mine has lasted a very long time and continues to treat me well unlike most of the other variators i broke in the past. the smoothness is what makes them amazing. when you get weights dialed in it will hold rpms pretty much from take off till belt travel is maxed out. also has a good drop in rpms for cruising and nice and responsive when you decide to hit it again. i dont miss my electric start one bit as a healthy motor will start fast anyways. 1-2 kicks usually.

If you get the larger variator too, set up properly it can. The e-start goes bye-bye though.

I think I’m going to have to get one, but that’ll be down the road a bit. Should probably make sure it gets assembled and runs before I toss more money at it lol.

usually a good idea. one other thing i will recommend is a heat gun for installing and removing bearings when splitting the cases. even a cheapo 20 dollar one from harbor freight can make life easier. another thing that can make life even easier is sanding the crank and cases very slightly like very slightly. my old boss always did it on his race motors and convinced me to. alot of members cringed when i said i did but im 10k miles in at this point and still have no issue. it just allows the bearings to slide on and off crank easier and slide in and out of the case easier if you plan on repairing the engine later on or swapping parts from time to time.
with slightly scuffed crank using emery cloth u can freeze crank and heat bearings and they slide right on. or u can freeze bearings and heat case and drop them right in. freeze crank and heat bearing and case and it will slide right in and not get stuck halfway and leave you freaking out. once case is stuck back together give the crank a good spin and check for tightness there may be some. put the crank nuts on both ends of the crank and give a light tap with a small whammer or plastic one if you have a stiff one laying around. it will relieve some tension depending on how you installed crank. it should spin pretty freely after. its pretty common practice in the car world with pressed bearings and pinions. after the bearings are set you ping it from both sides and life is good.
also i didnt mention in previous post but i gained some top end with my overrange due to gears it was atleast 15mph with stock gears it was atleast 10 mph. my stock variator was larger than most though so its not a direct correlation. with a true stock variator my bike was limited to 40 mph. with the stock one it had it was around 55.

That's the basic procedure I was going to follow with a few extra tips. Much appreciated. I really hope everything goes together relatively smoothly since I don't have easy access to a press. Know of a cheapish DIY press solution that isn't prone to ruining expensive parts?
I have a heat gun, blind bearing hole puller, and the case splitter and installer on the way so I hope I'm well enough prepared. Scoot Tuning order is arriving tomorrow!!

Side note... what are these holes for on my stock air box? My Jog air box’s don’t have these holes...   |

I assume the one on the inlet side is just a drain in case fuel spills in, but what about the other one on the outlet side?
