I really like the K&S variator , its just a little harder to tune in . this variator is much more sensitive and has to be tuned with the main clutch spring also. The first koso I ever bought was pretty good , but the others were almost impossible to tune and get good belt climb. I was running 9.5 gram weights in the last couple Koso's and that was with a 2000 main clutch spring. You did a great job tuning that thing up. I just did the 50mm BBK on my 50cc Jonway. I put in a 1500 clutch spring(those are a pain to get in the first time. The socket that fits it is the absolutely biggest socket I could find. The nut is a 38mm, but I couldn't find one in metric that big, so I found a 1-1/2" socket, which equals 38.1mm, and it worked!) Some 8g weights came with the BBK, but those kept me at about 5700 rpm, which is too low. The new variator I ordered came with 5g, but those hold me at about about 7300 rpm, which feels too high. I have some 7g ones coming in, and I think if I mix those with the 5's, I will be in the good. We shall see. I also got the 11 pole stator in. I hooked up the 7 wire reg/rect, and it has 3 DC outputs. I'm running everything off of DC, except the enricher, and the tail lights. I have 130 watts of lights hooked up in the front! It handles that no problem. I ride about 35 min in the morning in the dark. I have a little Tim Allen in me, too, because that is probably more than too much light, heh heh. Sounds like we have the same ride and BBK, I found 6.5g weights work the best. |

Sounds like we have the same ride and BBK, I found 6.5g weights work the best. Thanks. I had kind of narrowed it down to between 5.5-6.5g, you just made it much easier. Do you have the Jonway with the 12" wheels? If you look at JerryScript's pics at the bottom of his posts; the pic that says "my family's scooter collection", or something like that, the one on the far left, the red and black one, is exactly the one I have. Same colors and all. I love it. The big wheels, and the BBK is all I need. I teach school 1-1/2 miles from my house. I work at a clinic real early some mornings, too, and that is about a 35 min ride, but I enjoy the riding time, when it's not freezing or raining. I have no need for a car. I put earbuds in under my helmet, listen to some tunes, and I am good to go. I have enjoyed meeting all of you. I thought I was some kind of weirdo, scooter-dork. Good to know I'm not a complete social deviant, outcast.  |

I usually use a hammer and a flat head and knock the clutch nut loose . it can be a pain but it works. It would be nice to have a big socket , it would make it much quicker . These lights on the scoots are horrible ! I recently switched to an h4 bulb , my scoot has two headlight bulbs but I only have one h4 hooked up and it is perfect. |

If you don't have a compressor, and an impact wrench, get one! You can get a compressor that is fine for a backyard warrior for $100 or so. The 3 gallon pancake compressor works fine. It will run a paint gun, also
I don't know if the 150 clutch nut is the same size as the 50, but it probably is. I've seen it listed as both 38mm, and 39mm. The 1-1/2" socket from Autozone fits perfect on it. I think it costs around $20.
I had trouble trying to compress it, and get the nut back on. I held it on the ground with my feet to take it off, but the same method doesn't work to get it back on. I ended up having to get a buddy get it started while I held it compressed.

I have a craftsman 8 amp electric impact, I just don't have the socket. I also use my feet to take take the clutch apart , but I also do the same to get it back on. I even did it many times with the 2000 rpm main spring. I sit on the couch and make sure I'm sorta over top of the clutch a little more when compressing the spring. You also have to make sure the clutch pad center is turned right so it slides onto the shaft the right way . I've done it countless times over the past 4 years so I'm pretty good at it know, lol |

I should probably mention that I weight 211 lbs right now . I could imagine if someone who weighed about 170 lbs or lighter would ride my scoot . it would run a lot better ! Or maybe I should just loose the extra 40 lbs and find out for myself , lol. That's what I should weigh anyway. 40 lbs is a lot of extra weight for these small cc engines. I was up to about 225 ! About 15 years ago I thought of a great invention . I called it a weight vest! It was a vest that had a number of pockets which would each fit a rectangular 2.5 lbs weight. Every time you lost 2.5 lbs , you would add a 2.5 lbs weight to the vest." There would be pockets on the front and back so the weight was distributed evenly " . this would be great for athletes or even mma fighters " which are also athletes" . your legs and body would still feel as if you weighed 30-40 lbs more , and if you only took it off right before a game started , man you would feel as light as a feather. When I was in 10th grade I ran a 4.5 sec in the 40. This would have been very useful then . But of course my genius idea fell flat on its face when I looked up weight vest on the internet and saw my invention already for sale !! I understand about great ideas already being produced... I had one: "The BI-POLAR BEAR"... A cuddly, stuffed Teddy with smiling face. Turn the head around and it would grow fangs, drip blood and sport wolverine-claws... LOL! Already out there.
And you're right about the weight making a difference in performance! Back in 1962 I weighed 375 pounds, and my chopper would turn around 11.5 sec. at 130 mph in the quarter-mile. My biker-fanatic gal-friend was a diminutive 4' 6" and 76 pounds. With HER aboard, "Old Blue" would turn a scorching 10.5 or so @ over 130 mph... Of course, with "Janice the Flying Squirrel" at the controls, Old Blue was 300 pounds lighter than with the old chopper guy... And, the old Harley weighed only 350 pounds to begin with... I outweighed my own Hog... LOL!
I'm AMAZED at the torque of these scooters. Neither my old Chinese Xingyue 150 or the Kymco 250 lose much performance with a passenger aboard. Thinking back fifty years, it's hard to remember weighing 375... I wasn't all THAT fat! Kinda "large" though... LOL... Those are 24" ape-hangers I'm leaning on... See below... That's the only picture taken of me at 16, on Old Blue...
Today, I weigh 235... Wait! Since I got diabetes this year, and have been eating REALLY right, I'm down to 230... Woo-HOO! See... There's a good side to everything...
As for scooters, my all-round favorite class is the Chinese-style GY6 150, even if they're usually a couple of ponies short of a full team... LOL... I see a trend lately toward the Japanese, Taiwanese and other scoots opening a new class of 160 to 200 cc scoots, both simple, carbureted air-cooled, and complex fuel-injected water-cooled models. These in essence, are what we "tuners" of 150's would like to achieve, but seldom do... as in good acceleration AND 70+ mph speed.
While a little "pricey" these may be the "150 of the future". They only cost a little more than heavily-modding a new GY6, and bone-stock, they can run the freeways... About the same performance as my old Kymco 250. Pretty SWEET for a small, nimble scoot!
Even for an old-school, hard-core big-bike guy, these scooters are a hoot!
Ride safe,
Leo in Texas

I've been pretty bummed I could not watch the videos (except the one w/o the mph tracker - which, like you said, is not as fun). Then I thought - "I wonder if it's because of this crappy "Opera" browser Is witched to after mozilla did what they did to Brendan Eich" ...........
Sure enough - opened the page in Chrome and there it was! Fun to watch --- but you are one sick dude going at those speeds on a 2-lane road at 6am !!!!!!! no one has nad their coffee yet ..... odds of someone rolling over your butt are at least 2-to-1!
Tried the app but it does not work on an iphone. But you got me curious - has to be something similar. Will find it at some point. Thx!
Slow down! Kids. Wifey. Dad.

Honestly I usually don't ride that fast on back roads " usually " , even on the main road I usually don't , I have been more careful after the deer incident. Of course it only takes 1 time to really screw up. I'll def be more careful . Hey buddy , did you ever install the 2000 main spring ? It should get those rpms up for you . |

Of course it only takes 1 time to really screw up. I'll def be more careful . Hey buddy , did you ever install the 2000 main spring ? It should get those rpms up for you . Not yet. I have this Honda Goldwing that overheated about 2 months ago (liquid cooled) because of a stuck thermostat. Replaced a bunch of stuff in a major, pain in the project, then found one of the head gaskets was gone (because of the overheating). Just because I'm an idiot, took both heads off and replaced both. That was 2 months ago. Since then i have taken one head back off 5 times - including buying another used head. Why? Simply because the valves are clacking, and no matter what I do to adjust the valve clearance it will not fix it. To top it off - the side giving me an ulcer is the side that I did not need to mess with anyway. Yesterday I took the damned thing off again, ordered new gaskets and seals (about $80 each time), and am going to take it to a place and have it rebuilt. And if that does not work push the damned thing into a field and toast marshmellows with it. I've taken the heads off this thing about 6 times in the past. There has never, ever been any problem. Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr Anyway - if I never see another wrench again it will be too soon. So probably will not get to the clutch on the scoot until I go stupid again in a few weeks, presuming the place solves the clacking issue on the Goldwing.... |

WOW that is some impressive MPH bro!!!!
sign me up!!!
I am going to copy your set up but with NCY 61mm BBK and heads, maybe use 15x28 gearing if you think that would not be too high.

I am going to copy your set up but with NCY 61mm BBK and heads, maybe use 15x28 gearing if you think that would not be too high. 15:38 is good . if you go with the K&S variator , just remember you will more then likely need to purchase heavier variator weights. After I get a 1500 rpm main spring , I'll prob be using either. 15.5 or 16 gram weights. The nice thing about the k&s is that you will get full belt climb and should pick up a little more top end. With the 1500 rpm main I should have the CVT maxed out and I'm expecting close to the 70mph top end " on a straight run that is " . I'm at 7100 rpm on the straight runs , so if I can get my rpms up to 7500 then that's an extra 400 rpms , and if I can get the same belt climb , then that equals a higher top end. |

I forgot , you don't have 13" wheels do you ? If you have smaller 10" wheels ,then you may actually want to go with a taller gearing. I mentioned that I don't really like the taller gears for these scoots .I should have said I don't really like them for the 13" wheeled scoots. |
