[replyingto=tactics]tactics[/replyingto]Yeah, I highly doubt your bbk has anything to do with the wear on them, that's still rather strange. The variator nut tends to be ridiculously tight though. I've never heard of anyone lubing their variator, I think it can cause belt slippage and other issues. You can get a variator coated in teflon for nonstick purposes however. (though, I hear the teflon wears out kinda fast). My sliders looked pretty black after only 10-20 miles of driving with them, it could just be normal wear.  With chinese scooters you'll find that there are loads of parts that need replacing, loads of nuts overly loose, or overly tight, and all kind of mechanical "problems" that can be easily rectified by getting your hands dirty. You seem to be doing rather well for yourself in that respect  |

;D Well thank you, I used to do a lot of work on dirtbikes so once I hopped on here and read up a little I decided to go through everything the CVT and valves are a new concept to me. Everything I have worked with was chain driven and 2t. I was thinking with the BBK in I should be able to go up to 1.5 contra and shoe springs with no top end loss after reading up on the mechanics of the CVT a bit. I think I might lose out a bit on the 2k's. But I am not 100% on that. I would like to get all the acceleration and hill climb I can out of it. I use it mainly to get to work and I have a couple steep hills I tackle. It is doing a lot better with the bbk and the 8g rollers on the test drive but I lost acceleration with the heavier rollers.  But I don't want to try the 2k ad only be able to hit 30-35 mph either. I'm getting 50 top end right now. |

[replyingto=tactics]tactics[/replyingto]As far as I know, clutch springs don't effect your top end, just your bottom end (you won't be able to go slow speeds of 5mph anymore, etc.) I use 2k springs in my scooter and now the takeoff is great and I can still bury the needle going downhill. From what little I've read on torque springs, I believe those will effect your acceleration and such and needs to be balanced with your weight setup, however I could be wrong. Clutch springs are a great upgrade With 8g sliders you should be able to get better acceleration, but you may want to go down even more (8g sliders = 7g rollers) to 7g sliders. I don't have a bbk yet, but my slider weight is 6.5 and it seems to be a happy medium of good topend and good acceleration. |

I might just go with the 2k's then and check my variator/clutch ratio after. I have no idea how to balance it out and know what size contra to go with but I know for sure the stock 800 sucks and has got to go. After that bit of info I am getting the 2k clutch springs for sure though. Maybe the CVT guide here will help me out. I have the basic understanding on how it works. But no idea how to balance it out right. I'll remember that on the slider weight before I order them though thank for that bit of info. I'm hitting 50 on flat ground right now ( according to speedo ) just takes forever to get there starts creeping after 45 but that is plenty of top speed really, the only section of road I hit that is 50 is only about 3-4 blocks worth of road up a slight hill. |

[replyingto=tactics]tactics[/replyingto]It certainly is a balancing act, and it takes lots of practice. You may want to buy a variator tuning kit before you buy your dr. pulley sliders (dr. pulley is probably the best) this way you will know for sure what weight set is your favorite. Here's a link to one: www.scooterworks.com/prima-roller-weight-tuning-kit--16x13--3g-to-14g--products-1935.php#.Ua0poE1jjccThough, as Hank says, these are not meant to be every day weights they are made specifically to test the weight and then immediately be swapped with high quality weights. I think that even if you find yourself going too low in weight with the dr. pulley sliders, they push the variator out more by default so they should offer a higher top speed than even what you're getting now. If you'd like, you can mix your current weight setup for further testing, you probably have ~6 weights, and if you mix them (putting one every other weight) you'll get a whole new weight setup which might be preferable to the one you have now if acceleration is an issue. mixing 6 and 8 should give you similar to the takeoff of the stock weights, and similar to the top speed of the 8g weights, but not quite, somewhere inbetween. I love my 2k clutch springs. ;D |

So given the situation I did some research, checked my variator and clutch. I think 2k's should do just fine with the 8g rollers ( getting 6g sliders to try out too ) with the BBK. Combined Clutch/Contra / Powerlink belt / 6g sliders together on ebay and it's only $58.61 so friday I am just going to order it all slap it on when it gets here and see what happens.
