    Default Winter build CRF450 TSG

    Hey guys,

    I have a crf450 for 5 years now. I thought, why not check the engine and rebuild some stuff while I'm at it..

    First I ran the bike on a dynorun to see the power. Then I pulled the engine out and started inspecting it. Most stuff was still very good, it just needed some valve maintenance.

    I changed the clutch a year ago so that one was also good.

    I have some parts at the powdercoater, went for high gloss black, I hope they turn out nice!
    Some parts I'm repainting myself at home in my 'homemade' paintingshop..

    All linkbearing and steeringhead bearings will be replaced since the old ones aren't changed for like 10years or so..

    In short (the plans):

    - powdercoat some parts
    - paint some parts
    - check engine/ rebuild engine
    - some small new parts
    - replace link/steering bearings
    - rebuild rear shock
    - new tires
    - adjust carburation settings
    - maybe workout the airbox and put some fancy airfilter
    - new plastics
    - put my vapor in my handlebar mouse
    - maintenance the bike
    - led front light stuff

    That's about it.. now the photos: then, during build, still building, ....

    Your "homeade" painting shop looks like a CalEPA mandated booth for us Krylon warriors here in California. Hope they don't see this thread or I'll need one.

    Started rebuilding the engine. When I opened it, I was surprised. The engine was pretty good! Only needed some valve shimming, some new gasket. I replaced the head gasket, cil/piston gasket, reshimmed the intake valves, cleaned the valvehead, new spark plug and closed her up. This is where I'm now with the engine. Gone wait installing the clutch covers / ign covers untill the engine is back in the frame.

    I also sprayed the frame high gloss black and left some parts polished. It's a try out, what do yo guys think?

    Got the engine in this week. Installed some of the blacked-out parts.

    The rear shock is rebuild and got the spring powdercoated black. I also changend the rear link bearings, they were a pain in the ass

    Checked the carbu, set it up a bit more rich, since I'm planning to cut some of the airfilterbox out... But at the end I'll check the setup on the dyno.

    Went for new tires as well. Conti-attack SM.. I think they look great, any of you guys got some feedback on the tires?

    Next up is the wiring and front fork rebuild.

    I finished the bike, but waiting on some good weather to make some new shots
    Been running great, but a bit to lean because of the oversize air

    I see I'm not the only one with a super long obnoxious Leo Vince exhaust.

    One day I'll shorten it and move the can forward a bit... hopefully.

    Hehe, if you want to move the exhaust, you have to reweld it because the mountingpoint is fixed. Shortening is the only option that isn't to hard :(

    I got the bike finished. Been riding it a lot. Love how the suspension worked out. Which setups (compr/rebound) do you other CRF drivers use?
