Usually the 1/4" drive wrenches will be on the low end. Stay away from Harbor freight, their torque wrenches are not very accurate.

Thanks guys! I figured something was a little off. I'll definitely be looking into a new torque wrench. (My grampa mostly worked on Harley's and cars,so I guess this wrench worked well for that) moving down the spectrum lol
Edit: I found a new 3/8" wrench with 50-250 INCH POUND. Assuming the converter I used is right, that should be 4.16- 20.83 FOOT POUND, a good range for my 70cc cylinder torque settings.
With the 3/8" torque wrench, is it alright to use the little extender piece to fit the 1/4" sockets? Or does this affect the torque settings, and I should just find a 1/4"

Got the size of my MAIN JET today!  it is a 70. I also realize when comparing the jets on scootertuning to my main jet, it seems the top part without the threads is thicker than on my main jet. I've attached a pic of my jet, aswell as a jet from scootertuning. Are these jets the same or will the bigger top piece make a difference since it just sits on top?   |

Quoted by Niz76 , "with my 70cc setup and stock air box/snorkel removed I should look to getting 75-80-85-90-95". Should I consider getting in between sizes, with having my current main jet a 70?
Its very confusing some sites have sizes like 70,72,75,78,80,82,85,88,90etc. And some have going up in increments of 5, and others increments of 1!

It won't hurt if you're a little rich. Just make sure you check. If so go down to a 85 and try to tune the a/f. You don't wanna run lean. |

Yes definintrly don't wanna ruin my new engine 👍🏻 So I guess I'll look for 75-80-85-90. I know I have lots of question but these sizes are confusing me lol. Should I also grab any in between sizes? |

Well my air filter didn't exactly get "tuned" , just removal of the snorkel. What type of tuning did you mean just getting a new a/f that isn't stock? |

You don't need a new carb. Once you have a new jet in you adjust the a/f to allow the right amount of air and fuel into the carb. |

He means the Air/Fuel ratio adjustment screw on the carb. not the air filter. Hope this helps... Bill |

Well, just getting ready to order my parts... Brent recommended replacing my wrist pin bearing along with my new cylinder kit. I stumbled across 2 different 12mm size bearings on scootertuning; 12x16x13 and 12x16x16. Are these the same or are they different? They say there both for my Keeway. Does anyone have a post on which one I might get?  |

They are the same ID and OD, but different widths. 13mm would be the standard replacement for these.

I'm in a similar boat as you are, i have a 50cc 2 stroke scooter. I bought mine used, but mine didn't run so i already had to get some fixing done. Probably the biggest learning experience i got was taking it all apart slowly, looking at every piece, where it went and what it does, and comparing them side by side to all the pics and info on here. Plus just reading through the how it works and these super build scoots. If you get some time, read through the tech, the builds, and how carbs work (air flow, jet sizing) and how cvts work (variator rollers, clutch springs, and the contra springs) - that stuff will help you learn how to tune your ride to perfection. Glad to see you digging inside!

Glad to see you digging inside! Thanks Atari Guy! definitely end up doing lots of comparing to pics. But I am learning that the 2 strokes are fairly simple to understand if you are willing. I'm halfway there  it all started at my carb... why didn't I do this when I first go my scooter? Well it finally let me down this winter, and really, thank god for this forum otherwise I would paid lots of money for something I coulda done myself  After BBK installed, a CVT tune here I come ! |
