Alright so I've finally gotten a handle on carb tuning, next on my list would be to start upgrading the cvt so wound it be better to just save up and get something like this www.partsforscooters.com/169-159-GY6-Transmission-Kit?sc=31&category=132543Or should i go one part at a time? Two things I'm trying to improve. First my scooter doesn't really coast until under 2500ish rpm, it always feels like it's pulling to slow down. Second i would like to improve acceleration it's ok if i have to trade off a few mph i max out at about 56mph.at 7900rpm, the road i take to work is stop and go 45mph And I'm always the fasted,but not when it comes to starting from stopped. I don't really know what parts would be good to start out with or if I'll benefit from a package deal. Also i plan on replacing my belt with a gates still have the original on 6000km from when i bought it new. not sure if i should but exact same size or if there is different belt variations with different benefits. |

I was going to say , go with the ncy CVT kit , but man the price on it really shot up! I remember I paid around 150 or so for the clutch assembly . now its over $200 !
Actually that coasting probably won't get any better with a performance clutch. It all depends on the main spring . if you go with a stronger main spring then stock , the pulleynwill pull the belt back down the variator sooner causing a downshift feeling. But that's what you want for takeoff speed. I'd go with all 1500rpm springs . that will give you the takeoff you want without too much tension on the CVT. You'll have to tune the CVT with roller weights to your liking. If you can afford the full ncy kit for $299 , get it. If not then go with the hoca.

You will find almost everyone has their own opinion on this, but mine is this.... If you're going to upgrade the CVT and don't know alot about how the clutch spring, torque spring, slider vs roller, it may be best to select a kit... To further along with this, I suggest a kit of components that match.... Get an NCY Kit, Hoca Kit, Dr pulley, just don't mix dr pulley with NCY or NCY with KOSO, etc etc... Doesn't matter what you select, just what ever you go with, get matching components. I purchased this Kit from Ebay... It's a Taiwan seller but I had my item 5 days. After installing it, I ordered 2 more. At only $170.00 It is a great deal IMO!  |

I also agree ! , remember ncy is also. Taiwan made. You sometimes have to be careful buying a cheaper taiwan made part. More then likely its just a no name brand that says made in taiwan. Don't get me wrong , there are many good parts that are cheaper and made in taiwan. Just do a little research on the parts to see if u can find more out about the seller and the parts. If martin says he has it and its a quality part then that is a very good start. But if I had the extra cash , I'd go with a brand name taiwan part like ncy .

That's true , if u use the 1500 rpm clutch springs , they will disengane sooner allowing the scoot to coast a little earlier. |

What did you have backwards ? well, i deleted it so not to cause confusion but if you must know... said he could reduce his weights by a gram thinking it would reduce his rpms to 7,3000 but it would actually increase them to about 8500. anyhow, disregard this post to avoid confusion. |
