2002 Malaguti F12 Phantom LC Parts Suggestions

[coral]

Hello All!

I have recently been researching what I need to do to my scooter to get it to run properly and how to make it run smoothly, last week my scooter started leaking fuel really bad (petcock on tank leaking), I opened the cvt case and discovered the crankshaft to be damaged, pitting and burn marks on the variator and my exhaust was also having issues, as well as top speed being reduced by 20 mph and bogging on takeoff, so I have been deciding what to replace all of these parts with and given that I have never done any work on a small engine I would like some feedback on these parts:

Crankshaft: www.ebay.com/itm/Crank-Shaft-Stage6-R-T-10MM-Minarell-No-Reserve-/151589713576?hash=item234b7376a8:g:99QAAOSw1~JZSpuu&vxp=mtr
$230

Bearings/Seals: www.scooter-attack.com/crankshaft-bearings-stage6-r-t-s6-80366c4-rt-39.html?___store=sa_en
$95

Exaust: www.scooter-attack.com/exhaust-stage6-pro-replica-street-legal-s6-9116603-39.html
$175

Variator: www.scooter-attack.com/malossi-mhr-variator-aluminium-mbk-booster-nitro-m5115823-39.html
$115

Are these parts ok or am I going overkill/not enough - I am in the US so its hard to find these parts locally. Anything else I should be aware of to buy for my scoot? Also, it has a 70cc Stage6 MKII Sport on it. Finally, any belt recommendations? My main goal for this scooter is to be able to get up to 50mph like it did before I started having all these problems.

I would look here for some of this e parts Scooterpartsco.com. He has great prices on everything Malossi and is a very knowledgable scooter guy. I would call and see what he has and he will know what fits your scoot.

What problems are you having? My F12 did 55-60 with a pipe and street 70cc kit.

The pro replica is one of the hardest pipes to set up. I'd advise against it and suggest a Yasuni R, which has a powerband similar to the old Leo Vince ZX R. That was one of the easiest pipes to set up and worked really well on a variety of cylinders.
Don't forget to get some tuning weights for whatever pipe you end up buying.

Well first of all I accidentally stripped the crankshaft so then the variatior was wobbling and giving me issues like losing 20 mph off my top speed, bogging on take off, the splines in the crankshaft are also really messed up and it is hard to work on the bike now. Then my fuel tank started leaking and now I need a new air filter, new trim pieces, and new brake pads. Basically the bike needs to be rebuilt and cleaned. Before all of this happened I was maxing out at 48 MPH and my takeoff had so much torque I could do a wheelie without trying.

Oh, you also shouldn't buy that crank in a 10mm. Get it in a 12mm and use a reducer bearing. This way you have a good crank for a stronger build later.

scootertuning.ca/en/crankshafts/25012-small-end-bearing-stage6-12mm-12x16x13mm.html?search_query=reduction+bearing&results=7

There was another one on there but it said for original crankshafts only. Im doing a crank swap with an upgraded crank.

That's the one it says cant be used with stage 6 cranks, or is it fine?

[spaz12]

They must have just started saying that. As a matter of fact, other sites do not say that.

Maxiscoot doesn't say it either.

Call scooter tuning tomorrow on the 800 number and ask them about it.
