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, ....
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?
