Budget Mods so far....
The things I've installed that increase the performance of the StradaVariator to date, costing me $ are:
-$21.00-12 gram siding rollers
-$7.00-an iridium plug
-$28.00-a hotter coil
-$8.00-an International Cub tractor fuel filter
-$4.00-bigger main jet
-$2.00-hose clamps to reinforce and open up air intake hose
Maintenance Items that may affect performance
-$20-Gates CVT Belt, 835 20 30
-synthetic oils in both engine and tranny(after breakin)
-balanced my front tire which had a shake between 43-47mph
Things I've done that cost nothing:
-Open up the stock airbox
-Rerouted and shortened fuel lines to prevent getting kinked or pinched
-Cut the sharp 90 degree bend off of the muffler outlet
-drilled holes in endplate of muffler
-used a dremel to clean up(grind and polish) inside both ends of header pipe
-adjusted fuel mixture screw on carb
-used a dremel to polish intake manifold and spacer
-removed rubber snorkel from the CVT inlet and put a piece of window screen over it for better cooling
Cost of performance items planned for spring
-$15.00 Clutch springs
-$10.00 Crankcase cooling fins
-$4.00 Shim for clutch torque spring
The other thing that affects performance, but which I already had, and would get for personal comfort regardless of performance is the Puig touring windshield.
$119.00-Total cost so far of optional and planned performance items
After comparing my results so far to performance results from people who have done extensive bolt-ons, when finished there will be only a little difference between the performance of the StradaVariator and similiar 150cc GY6 scoots with bolt-on mods costing many $$ more. Certainly not enough for me to want to spend that much money for such small additional gains.
carborator jets
Why didn't you replace the idle jet when you replaced the main jet. wouldn't that make it run better?
Carb Idle jet
At the time I did the order that included jets, only the stock idle jet was in stock. It would have been better to replace it at the same time, but the places that had the jet I needed, would have charged $9.00 shipping for just a couple of jets. I didn't want to try to drill the idle jet either because the only bits I have that size are for a dremel and break too easily.

I dont know if anyone out there knows this But I have just found something out about my variator. You have to make sure at Wide Open Throttle your belt is going all the way to the top of the (variator) pulley. If not you will be turning A LOT of RPMs. Heres what to do, Take it apart and file off the center (rear side) of the front half of pulley The one with the fan blades on it. After filing awhile hold the two halves together and lay the belt in it. See how far up the belt will be riding. Keep filing till you get the belt up to the top of pulley. Reassemble and test run. I am running 14g weights. I weigh 190lbs. The scoot had tremendous pull with 14s. I went from running about 55 top speed turning 8K rpms to running about 63 mph turning only 6K rpms Hope this helps out thanks neil
I hadn't thought of doing
I hadn't thought of doing that, but will be getting into my CVT for a bit of work on the clutch(springs) sometime soon, and will check that out. Thanks.
