You don't want to run a heavier torque spring unless you've got belt slipping. You don't have the horse power waste on excessive belt tension Just use liter than stock veriator sliders It does the same thing but with more power to the wheel Try to get your clutch to grab just before or the same RPM as the veriator starts to climb and that should be at a about 6000 RPM for best launch Using light weight sliders does NOT reduce top speed. But worn out belts and veriators do Light weight sliders do however use more gas until the variator maxed out but then it's all the same You know when your veriator is maxed out as RPM will start to climb  Chewy's right on the $$$$ here. Mine is set up to launch at around 6,200....... |

Best the Gringos learn to ride at home.
Brainless thing to do is never been on two wheels before then got to a foreign country usually in party form to give it a try.
Anywhere I've been out of country with Scooters the Travel agents and Pod people (Cruise ship) adamantly warn there Gringos Not to rent the Scooters.
Its got to the point its Afternoon entertainment after a half day of Diving to pop a cold one and watch the Pod people crash Scooters...

I might your ancer I have a 2008 Short wheel base engine it had 13 inch wheels on it it had 400 miles on it. It does not have any extra parts on it the motor has never been open up.no stator,no brakes I baught the scooter and the wire harness shorted out so I used the parts off it for my other scooter. With my back I needed a longer frame. I live in Middlefield Ohio 44062. 40 miles south east of Cleveland Ohio If you can use it let me know. Oh wow Middlefield. close to were grew up. And I can't miss "The Great Geauga County Fair" in a week. |

Oh --- I just learned something (I think) --- again, I mainly know 4T's. But, now I've read 2T's need a vacuum below the piston. So - a seal would screw that up. My mech. will probably know this, just did not put it together yet. Am I thinking right? Other ideas? Again .. we have to cover the intake to start. It will idle a few seconds, then the rpms will start increasing. In 10 seconds it's like full throttle. Have to cover intake to stop it, kill switch, key will not work (they do at idle). Yes a 2-T Crankcase Is Pressurized, A Runaway Throttle on 2-T is Classic Massive Air Leak. If Not the Intake Spigot even the Case halves themselves maybe leaking around the Crank Area. #1 If it Smokes its Sucking Transmission Oil. (white smoke). #2 If the Throttle Runs Away its a Massive Air Leak. Good luck |

Not Just the Crank or Crank Seals but the Intake Boot or Spigot itself or anywhere there is Air Available to leak.If ya can get it running Spray with some WD-40 and the when she sucks that it should slightly bogg or some use Contact cleaner or Sketchy but I like Starting fluid, the rpm will jump when the engine smells the Ether Starting fluid. Be careful....

True I guess I could start the dyno once it goes into high gear. If I start it low I get a quick rise on the chart then it starts dropping as it goes in to high gear. I got the variator, clutch, bell and torque spring put on last night. I used the 13g sliders, yellow torque spring and blue clutch springs. Acceleration on the road improved but I'm having an issue with top speed because it don't want to rev much over 7000 rpm. It doesn't matter if I'm on a long straight or going down hill. I have a couple guesses on this but not sure any of them make sense. 1) I didn't get the exhaust done so would the stock muffler be so restrictive it's stopping the engine from revving any higher? 2) is it running to lean and not letting it rev out? Haven't checked it on the dyno but plug looks lean 3) are 13g sliders to heavy to let it rev? The stock weights were 14g 4) would the stock zuma cdi be limited to around 7000? It's an 02 50cc cdi Also I thought the stock belt would be 842 since it is the long case but it has an 835. Do you think that would be to short to let the variator close all the way? There is a decent size gap between the top and where the belt is going to. I'm not sure if I should keep testing or not. I'm afraid of taking the clutch apart again because the threads on the big nut didn't look good when I took it apart. It went back together fine and tightened up good but I don't have an extra if it strips. Stock Headpipe Pics. www.dansgaragetalk.com/topic/81-150cc-stock-head-pipe-woes/This was my Headpipe. They Welded the Flange on incorrect then left the Flashing and a Goober of Weld behind. The Stock Headpipe is Smaller than your Exhaust Port. The First mod I would recommend would be a Proper Pipe then Uni Filter, and jet the Stock Carb. Also Check your Belt Climb, Draw a line with a Sharpie and see if our using al the Vari face available. |
