    Don't do it. The new electric bikes just aren't there yet.

    Heavy, with an extremely short range.


    -Kyle, if you do go with a new reed cage, I recommend Boyesen as well. Threw one on my YZ with 1 step leaner jetting and the bike is running crisper as ever!

    Brand new boyesen rad valve in last night. Fucking nothing.

    Tried starter fluid today (I know it's not the best). Nothing.

    Tried fuel straight down the plug hole. Nothing. Probably bringing it to Manchester ktm this week.

    I quit

    welp. i have 100% determined the problem.

    Woodruff key that is supposed to index the flywheel to the crank sheered in half. Flywheel was almost a half turn advanced for timing, or more than a half turn retarded, depending how you look at it.

    I cleaned out a pilot jet with a guitar string today. after a few kicks i got a stumble, like it wanted to go but wasn't. figured the cylinder was finally filling with fuel and after a few kicks of filling, the off time spark was enough to ignite that fuel.

    Stator cover off, stator off, flywheel off, no key at all. cleaned it and saw that there was infact a groove on each piece, but the key was sheared off flush. Tapped it out and it was clear.

    So now i either order one for $0.95, pay like $10 to ship and wait a week. or i go to an autoparts store, buy a generic one and file it till it fits?

    They sell keyways in different sizes. We have several sizes here at work that we cut to length. If you can't find one in a timely manner so be it. If not measure the width and I'll see what we have here. I'm in NH Sun-Tues 3-11pm or we can figure out another time later in the week.

    thanks. I believe its 3mm thick. not very large, about dime sized.

    Problem is that its in pieces, so getting height and length isn't really an option.

    If you can find dimensions from a source I can have. Machinist at work cut one for you

    OEM Key came in. its identical to the YZ250 one that i got and installed to test. i'm leaving it and buttoning everything back up.

    Only remaining problem is that i replaced the Shift shaft seal with brand new OEM, and now it leaks worse....

    There is a collar/spacer and an o-ring in/around that seal. Make sure you replace those as well.

    EDIT - If any of those are out of round, oil will get by and a new seal isn't going to make a difference. All balls racing makes a kit for like $17 I think.

    Yup, this one. https://www.allballsracing.com/25-4003.html


    Whoops. I thought you meant the countershaft seal. Disregard.
