    I’m using a CRF 230 lever. It’s 4” long center to center. It fits the shaft nicely but takes a little tweaking to clear the cases.

    I ground out the back to make it softer with these reports of bent shafts. Stock, it’s a little stiffer than I’d like. EDC63020-FD85-4061-9DFA-D3A4D333C82A.jpeg EB4D71D8-8FA4-4E6E-A2D8-7C21946FB0CC.jpeg

    Props to Navin for hooking me up with a shorter shifter. A little closer to the engine but works fine. Good option for normal size feet.

    Awesome! It wasn't good for my feet on the older E but if anyone else wants to find it, here is the Ebay listing.

    Was this bike getting fuel injection this year, and 6 speed? And across to the "S" small wheel bike? Thanks for any info.

    Carbs for now and the S is still the "old" E 5 speed as I understand it. The E has a 6.

    Has anyone used and have feedback on the 4 degree offset flywheel key to advance the timing?

    Recently installed the 4 degree key on my first gen 250E. This has helped with low end grunt and I can more easily lift the front wheel. I would do this mod again. To date the best improvement for low end grunt was setting the mixture/jetting correctly and this 4 degree key from Joe Kenner has further improved grunt.

    From your July 9 th post, are you still running the 45 pilot and 130 main? Have you played with the needle?

    Aceribix X-factory handguards were an easy fit. Only had drill out handlebar ends to 5/8.

    On a side note, one of the threaded holes in my front hub came stripped from the factory. Not sure best way to fix?

    Did you run a tap thru it? Id contact GPX for that but if you wanted to avoid shipping and waiting a timesert/helicoil is a permanent and better thread than bare aluminum threads.

    Bolt slides in and out of hole. Definitely not wanting to ship anything back - will try helicoil pending Gary's response. Thanks

    I happen to be eating lunch next to my E so I gave it a look... you can probably slip a nut on the other side and use a longer 6mm bolt to get by for now. The KTM hubs used to be that way in the older days.

    That worked but had to go with smaller dia hdwr due to spoke interference. May leave it this way rather than risk weakening the hub with a drilling larger hole for helicoil?

    Id call that a temp fix, (though Im sure its fine). I think a thread sert would be better than new but see what Gary has to say if its a brand new bike. I guess the wheel guy in the plant got a bit over zealous with an impact driver. :lol3

    Yes. Keep in mind that my first gen 250E has the Keihin style carb and I've heard that newer 250E's are using a different carb so my mixture settings may not work on a different carb. Since making this jetting change I've been operating from sea level to 5000 feet elevation but mostly 2000' - 4000' and the plug is clean although slightly darker than before. I have not changed the needle height or anything else about the needle - maybe there's some additional tuning opportunity with this. My goal is better low end grunt.

    I have the first generation as well. I will try the larger jets. And the 4 degree flywheel key. Thanks!

    58 miles of mostly sand trails in Ocala and the bike did great.
