gitsum 16 Posted June 27, 2013 Share Posted June 27, 2013 Some of the bigger more complex scooters have an electronically controlled CVT, or something other than a simple CVT. The simple CVT simpy uses centrifugal force to open and close ramped pulleys to alter the gear ratios. It's kind of like a constant velocity carburetor, it's really old technology, but it still works very well and is extremely reliable and efficient, even when compared to modern electronically controlled versions. That being said, Kymco has a 300cc scooter engine that produces 29+ horsepower and still uses the good 'ole mechanical CVT design. Link to post Share on other sites
Classing 6 Posted June 27, 2013 Share Posted June 27, 2013 Personally I think CVT's should left be where they belong.. On scooters. I used to be into quads and all my riding buddies with the 4x4s would get into the heavy mud and every one of the cvts would slip and burn up belts. Give me gears and a clutch! The only thing that will ever go bad (in most cases) is a clutch,pressure plate and throwout bearing every now and then and on rare occasions a synchronizer or 2 (automotive applications). Cvt is a simple design and works very well for light duty applications. I cant even imagine having a cvt in anything automotive and towing with it. Link to post Share on other sites
Hobo1 8 Posted June 30, 2013 Share Posted June 30, 2013 Six speed multi clutch auto would have been a better choice. Yes! I would love to have a 6-speed manual too though :/ Link to post Share on other sites
brillo 4 Posted July 20, 2013 Share Posted July 20, 2013 Anyone know where the CVT is built (in the US I hope but don't know) Link to post Share on other sites
FelixTheSpark 0 Posted July 24, 2013 Share Posted July 24, 2013 Jalapeño is still in the catalogue... They dropped Techno Pink and replaced it with Grape Ice... I guess girls (and some guys) will be disappointed... Another big update they introduced in 2014 (apart from the CVT) is the bigger side mirrors... Which is something I always disliked about my 2013 Spark, how small they are. They create a lot of blind spots, especially when changing lanes... And I don't know why Chevy USA made them smaller like that, just for the US market, since all around the world the Sparks have big mirrors, like the Cruze. And of course, there is the issue with the illumination of the steering wheel buttons (for MyLink equipped units). Which leads me to wonder if the power window controls on the driver side door are supposed to illuminate too... Cause mine don't. Link to post Share on other sites
malibuguy 14 Posted July 24, 2013 Share Posted July 24, 2013 ^ i agree about the mirrors...once i get them set right...they are ok...but damn i really cant see shit out of them Link to post Share on other sites
WaltK 305 Posted July 24, 2013 Share Posted July 24, 2013 The mirrors are a little on the small side, what makes it worse is the way they taper down, on the outer edges. I am using a couple of those stick on 'blind spot' mirrors, but they aren't much help. Link to post Share on other sites
bluer101 241 Posted July 24, 2013 Share Posted July 24, 2013 I have the stick on blind spot mirrors too, I put them on all our vehicles. At first with the Spark was hard but now I'm used to the small mirrors. Link to post Share on other sites
FelixTheSpark 0 Posted July 24, 2013 Share Posted July 24, 2013 I just checked the Chevy website and the new bigger mirrors are only available for the 2LT Link to post Share on other sites
brillo 4 Posted July 24, 2013 Share Posted July 24, 2013 Had not heard no can make CVT's work, everyone I know (including me) love theirs, smooth as a warm knife thru butter & trouble free - question, is GM using CVT's by Jatco ? Link to post Share on other sites
