    The filter oil in an applicator bottle is a good idea I may steal that.
    The grease you put around the airbox flange I would also put on the air boot where it meets the carb and on the boot from reeds to carb.

    HAPPY HAPPY!! That first fire up after a full rebuild is typical (more than a few kicks) for some reason. The bike will start after one or two kicks here on out. An added advantage is you actually know this bike and will be able to diagnose trailside repairs if something goes wrong.I really enjoyed your build on this machine. The bike is really looking good.

    Love it Rado!!! Been watching and following you for quite awhile since I've been trying to recover from an injury in 2018 that exacerbated medical problems from accidents and deployments in military service...love your appreciation for our creator and the many blessings like dirt bikes in our life. :) Would love to ride with you one day, however, I live in northern washington just 2 hours shy from the Canadian border in the Cascade Mountain range. God is still helping me get stronger to ride and function in daily life better, and dirt bikes help me excel mentally and physically in my recovery from things like liver disease from years of hard meds, ortho probs, seizures, and even my trauma induced type II Narcolepsy among others that I don't feel like listing. God bless you and your work, and may more prosperity and health come to you and your family! You are an encouragement to not be shy of your beliefs. You are welcome to borrow my new TM EN300ES ANYTIME brother! ;)

      @@dirtniron My first bikes were always Husqvarnas so I was real handy with my left leg.....all the Husky's were left-hand start in those days.......now all you primadonnas have a push-button starter. I'm just giving you some grief, Rado. I should get rid of the bikes I have and get a button start if I get a new bike. Both of my knees and shoulders are shot, as well as my back. I've got organ donor on my driver's license but I can just see them if I croak......they'd probably roll me over and say that there was nothing left on me that the medics could use! Ha.

    Why do people call it a "build", when all they're doing is assembling parts already built by the manufacturer's ?
