3 blue clutch springs in the kit only. 1000rpm. You will need the main 1000 rpm clutch spring also. The big one that keeps the pulley closed. If u use the three without at least 1000 rpm main spring then the pulley will begin to open before the clutch engages. U don't have to match the springs , you can go with the 3 1000 rpm clutch springs and a stiffer 1500 rpm main spring , but u cannot go the other way , stiffer clutch springs then the main spring . |

I checked it out and the kit came with "1000" rpm springs. Blue ones. Sorry about that , I kept saying 1500 rpm springs. So u have the three clutch springs and the 1 main spring ? |

So in my best interest... Put the blue "1500" springs in and go from there. If it were me , I'd def give it a shot and see how I liked it. Do in have a 1500 main spring also ? |

Gates belts are now made in China, and the quality is not that great. If you want a really good belt, go to Scrappydogscooters.com, who commented in this thread, and get a kevlar(aramid) belt. The aramid belts from Scrappy's is 100X the quality of any Gates you can get these days. Trust me on this. Gates belts have been made in China for years and are still the best. Just because its made in China does not mean its junk . its the fake stuff made in China that's junk . many real companies are based in China " I don't like it " but they still use quality rubber and fibers and have great QC. |

Stiffer springs help with better takeoff and you should still have the same top speed as long as the CVT is tuned correctly .

I was just wondering if it was worth taking my clutch apart to swap the springs? I have watched the how to videos. Just wanted to save myself some "unnecessary" work. Its all up to you . just remember if you use stiffer clutch springs , you must use a stiffer main spring. If not , the clutch pulley will begin to open before the clutch engages. |

And that's why you up the final drive gears! Yeah, that's why the first thing done was to gear up to 16/36 - not the lowest ratio commercially available, but pretty close to it. All of this variator tuning is AFTER putting in taller gears. These scoots are made with parts that are meant to be ran at a certain rpm range. Meaning the CVT will perform the best running at such and such rpm with such and such weights . so let's all of a sudden jump up to 10k !! Well first we need to drop the variator weights significantly to even reach 10k , now at 10k the variator is not spinning the weights fast enough to push the belt up as high as it was running before . No matter what we do we already know the power the engine is putting out. I'm guessing with stock gears , the engine will have enough power to spin 15 gram rollers at 7500-8000 rpms and get full belt climb . but in order to reach 10k you will now need to drop to around 10 gram weights . now will this setup " stock gears and full belt climb " give u a better top speed ? Not sure since full belt climb is not being achieved at this time. But when it comes to hitting 10k with this setup , the top speed may still end up being the same as with the 15 gram weights at 8k . it seems the ratio of rm to weight needed goes up and up as the roller weight drops. This is more then likely due to the way the CVT parts are made. I'm sure they are made considering the redline on these scoots are 8k. It just seems like when we try to push these scoots as fast as we can , we always run into the 8k roadblock . when we use lighter weights for more rpms we tend to loose mph . no matter what a variator is built so it takes a certain roller weight at a certain rpm to push the belt up the variator face fully" at some point u need more power to gain more mph" Yes you can use a lighter weight and a higher rpm , but like I said , after dropping even one gram and gaining a good 500 rpm , my belt travel dropped and I was unable to reach full belt climb. Just maybe one can tune the CVT to reach 10k and possibly gain a few mph , but for what ? higher engine temps ? And wondering how long she'll hold up ? |

And that's why you up the final drive gears! But what happens when u up the gears even more then already done ? U need even lighter weights to get up to 10k. Or go with gears closer to stock , but then you would have to do the comparison all over again , and it would be pretty much the same outcome. Using taller gears puts more stress on the engine therefore you need lighter weights to hit a certain rpm. Even with stock gears you may reach 10k with 10 ram weights , but now the gearing is too low and you still probably only running at the same mph !! |

Is your scoot ac or DC ?

This is why everything was not adding up . I didn't want him to replace the top end if he didn't have to. Its usually something simple that's why I mentioned a possible weak battery . I had this issue many times over the years. These batteries tend to die pretty easy . I'd still buy a new plug , but it may just fire up without it. I'm just not sure why the scoot shut down while it was running?

That's exactly why I mentioned it!! Your battery is very weak . you can see it doesn't even turn over most of the time.
So everyone was giving advice but was unable to watch the video ? And I was the first to mention the video not working ? Wow
Take my advice and jump the scoot with a car . it does not matter if the car is running , it will not hurt the scoot . Ive done it many times, just don't rev the cars engine just to be safe.
I just can't believe that everyone was giving advice but never was able to watch the video . if someone was able to watch the video , how did they miss the weak battery or possibly starter clutch issue.

You do know the plug boot , wire and coil all screw into each other right? That is one of the more common issues . while riding the vibration causes the wire or boot to vibrate loose , and the scoot dies. If you didn't check to make sure they are all screwed together good , I'd def do that also.

What really bothers me is that it sounds as if your rings are ok " no smoke and compression " , and when u bypass the carb and squirt fuel into the engine there is no ignition . that points more to a plug , or ignition issue.

Just for the heck of it , I'd buy a new plug remove the air filter and jump the scoot from a car . this way you can rule out a weak ignition. Try first with the filter in and then with the filter out. This will also cover any scenario where your scoot is for some reason running either too rich or too lean .

Was it a nice strong spark ? It would suck to tear it apart and it ends up being something simple. No smoking exhaust ? I would expect to see some smoke if the rings were bad . no noise while trying to start the scoot ? I tried to watch the video but it won't play for me . does the battery seem strong ? Also is the scoot ac or DC " when it comes to the cdi" a DC scoot will do exactly what yours is doing if the battery is really weak. Just trying to cover everything. I'd like to be able to hear the scoot turn over so I can hear if the battery is weak or not.
