TBA , I probably should not knock the higher gearing , even with 13" wheels. I have never actually tried them . I only said this because it seems that many with the taller gears cannot reach the same speeds that i can . even with bigger bbk kits then what my scoot has , it seems as if im still reaching higher speeds. When it comes to the 10" wheels, I would not be worried at all going with 16:37 . I just wanted to clear that up , since I never actually tried anything other than 14:38. This is just my opinion so please don't hold me to it , lol.

It just may be that the lower gears will work better if you have less power,,I cruise at 50 mph 6k rpm barely crackin the throttle and pull big hills at over 40 mph,,and thats where I really spend alot of my time at,,if I had lower or stock gears I would be close to 7K at 50 mph,,I know my variator is not pushing my belt all the way too the top so I really have to get a better variator sooner or later,,especially now that I got the NCY clutch and all,,minus well do it right,,i bet a better variator will really help out,,my scoot will only do around 64 MPH at 7.5K rpm. Hey Geh,,I found a socket that fits the big clutch nut at Auto Zone for like $8 or so,,I think it was 1-1/4" I will look tomorrow,,I think its supposed to be metric but this one fits perfect  |

Yes I have the 10" wheels, I have the Hoca Race variator and my belt is climbing all the way up, Next time I open it up I'll take pics  Thanks for all the advise. I think I will eventually try the 15x38 gearing if I ever get the BBK. I am trying to convince my buddy and we will do it together, your video is helping convince him... haha |

There are many that think the 65-70 mph range is nearly impossible for a carb'd 150cc gy6 even with the upgrades. I'm glad its inspiring others ! |

I hit 50 pretty much right at 6k , 60 around 6800 rpms . then as I reach the 7k range my belt must raise up a little higher , because I've been maxim out around 7100 rpms on a straight run at 66 mph. The 1500 main spring should keep the belt from raising up the variator until closer to 7500 rpms . if I can get the extra horse power to kick in , I should be able to hold the 7500 rpms with the belt at full climb. Right now I do not have the horse power to crack the 7100 rpm mark on the straight run. So all I need to do is postpone the belt climb a little . the 2000 kept the clutch closed too long , and was not getting full climb until over 8k . I'll have to get one of those sockets , thanks for letting me know. |

Also the 1.5k will allow my belt to climb all the way up on the variator sooner giving me a lower rpm at a higher speed? Thats what I need.. |

Also the 1.5k will allow my belt to climb all the way up on the variator sooner giving me a lower rpm at a higher speed? Thats what I need.. I believe the stock main and stock clutch springs are 1000 rpm. I have all stock springs in right now , and my clutch engages around 2700 - 3000 rpms. My scoot will surge around 2700 to 3000 rpms like it wants to take off at warmup , because the clutch is beginning to engage. Some say they are 500 or 750 rpm but if that were true the clutch would engage much sooner. Usually when our scoots warm up the rpms are pretty close to 3000 , so I'm not sure why the main would be a 500 or 750 . for instance a 2000 main is rated to engag 2000 rpms above recommended idle " which is 1700 rpms ". If you are running a stock main the only way to run a higher mph at a lower rpm would be heavier weights , and that's if the scoot has the power to turn the heavier weights so that You can reach a higher speed at a lower rpm. I'd like to see what a 28mm carb does for your scoots performance. |

Yeah me too,,I bet it wouldn't hurt having a bigger carb,,my clutch starts engaging around 2700 like yours with the stock springs,,but Im not too sure about the contra spring,,dont know which way to go with it,,its a stock spring now and i dont know what size it is. |

I would expect the stock main spring to be rated the same a s the three clutch springs. But then again why would they have the clutch pulley opening right at takeoff ? I would expect the pulley should at least stay closed for a another 1000 or more Rpms. Since the clutch springs are rated to engage at a certain rpm after idle , I bet the main spring is rated to start opening at a certain rpm after the clutch engages. For instance the clutch pulley would open 1000 rpms after the clutch fully engages. Which would be closer to 4000 rpms " when the clutch pulley would begin to open " |

I'm thinking about doing another speed run video in the morning " if it doesn't rain  " if I do I'll try to get the video a little steadier . there is a hill I can more then likely hit over 80mph on ! , lol. I'll give it a shot ! Should be fun . |
