Is there any HARM in mixing three 14 gram Dr Pulley sliders with three 10 gram sliders so that I'm essentially running 12 gram sliders?

You can try it but I have tried mixing and I always lost top end.

Don't want that. I do like the quicker pick up with the lighter weights. I've read your post on clutch and contra springs. Can we get a little more top end with the right selection of those two. I had a hard time fully understanding your post, about springs, but it wasn't you.

When it comes to mixing sliders you must be careful not to mix two weights that are that far apart . it will more than likely make it easier for a slider to fill out of place on you . |

I had a hard time fully understanding your post, about springs, but it wasn't you. No you will not get more top end changing springs: If you change the Clutch pad springs to stronger springs all that is going to do is require more higher rpms before enough centrifugal force is created to throw out the arm pads and graba the bell to turn your rear wheel. Putting in a stronger Contra spring all that is doing is putting more pressure on the belt in other words it wants to close and keep the belt up high on the pulley. By doing so it also requires more rpms so that the Belt in the Variator climbs up and puts enough force on the clutch pulley to open up and allow the belt to drop for more top end speed. In addition it wears out your belts more due to the extra pressure and more heat it creates. I like the lightest in both sections, that way you don't require the motor to rev up so much to get the scoot to move. You can then cruise around with low rpms and low mph and not be throttling to keep the rpms up to keep the clutch from disengaging at a lower speed. Think of it as a manual car, when you push the clutch in and rev the motor and then release the clutch. My trike is 350lbs and I am 180lbs and I have it setup so that it starts to move all that weight at 2300 rpms . Alleyoop |

I always wondered that . some say they are 1000 rpm rated . that's if u use a stock springs. The rpm rating is based on how many rpms above preferred idle the clutch begins to engage. I am using a 2000 rpm main with 1500 rpm clutch springs. Since I'm using a 2000 main my clutch is beginning to engage near 3500 rpms. U would think it should engage closer to 3200 rpms but the 2000 rpm main is actually holding the engagement back slightly because it causes the pulley to stay closed longer . if I were to use a 1500 main spring the pulley would begin to open sooner speeding up the clutch engagement. |

Alleyoop I slightly disagree about gaining top end from changing springs . you will not gain top end from changing the three clutch springs however you may gain top end from installing a stronger main spring . how is this possible ? While the stronger main spring will allow for higher rpms through out low and mid range , it usually allows the engine to reach a higher top rpm easier therefore you should reach a higher rpm before the clutch fully opens allowing the engine to possibly reach a higher top rpm with the same size variator weights causing a higher top speed . That is because when the clutch pulley open fully it is now at a higher rpm . |
