T5 very noisy when change flywheel...HELp...

Postby NRS » Sat Jan 28, 2012 2:20 pm

please help me, I have replaced my T5 with a racing flywheel, weighing around 850gr, but now my machine is very noisy when idle, when I pull the clutch, the noise is gone ... I was quite surprised with this case .., i use the stock clutch, I also use stock crank with 20mm cut, ball bearing also all good .. i dont know what it is ..... :cry: :cry:

If its a T5 engine put it back to standard flywheel.
Finest engine ever made for a Vespa.

let me guess... Its a different taper. So flywheel is knocking shit out of stator. When you pull clutch in the bit of crank float all t5's have keeps flywheel away from stator windings...

As previously stated its a t5 leave it alone.

Use OEM parts, or parts made for your damn scooter.

You want to be macgyver? Go the fuck ahead and fuck off about shit breaking.

I think what Travis was really trying to say was... When you're trying to go Fast... you have to step back, and ask yourself: "What would MacGyver do?"
Well, in this case, you need to reference Season 3 / Episode 6 "Blue Smoke, Brown Water" in which Mac had to improvise, build a scooter and win the race in order to save his friend from the evil :vamp: drug lord: Slo Lam :-o
He had some investigating to do :sherlock:
He used the husks from the Coochioo-Nut plant(similar to our Native American corn :usa ) (ground up with water, made into a paste and then sun-dried) to form perfect high performance clutch plates... No slip or drag, much better than cork :P
:idea: of course a hollowed out coconut halve served as the clutch cover. Local indigenous vines proved far stronger, and smoother operating than even the most expensive clutch, brake and gear cables :thumbsup A section of large, mature bamboo was an able piston, and fit perfectly into the bored out center of a faux-jade Buddha statuette. The Buddha had to be turned and cut so his bulbous belly would become the head to this truly "enlightened" barrel :angel2: bit and pieces out of a refuse bin behind the Nike factory did most of the heavy lifting in terms of his fuel delivery system :-D and 16 empty Fanta cans (assorted flavors), patchworked together made one mean exhaust :onfire:
Needless to say, Macgyver won the race :imperial , his friend was saved and Slo Lam was captured :cop and sent BACK to the repair shop...
So, when you want to make your scooter go Fast... just think: What would MacGyver do :?: and remember.. Correct parts, and stock components don't mean anything :!:
Correct Parts= :cry:
MacGyver/do it yourself Parts= :rocker
In these times of contention it's not my intention to make things plain

light flyweels are not always noisy and don't always need hi idle... I've addapted Vespatronic ignitions for my T5s and the results are impressive : more torque, more top speed, less fuel, more fun... with still the same idle.
(light Vespatronic = 1050g)

I have tried that with original carb (with fuel pump), original exhaust, original crank, with Malossi kit a bit re-worked (120*/180*) and personal designed head (primary gearing 21/68) :
more than 16HP on the dyno and 19HP with an old SIP perf exhaust.

:roll:
