2013 EC250R - 65Hr Report/Review

[Jakobi]

Haha Steve! I'm flat out getting a hall pass to go riding at the moment. Don't like the chance of an international holdiay (Thats the reason I'm working, and playing, stretching this out, and not just riding it like I had been).

[Jakobi]

Got a bit more time into it this afternoon.

Cleaned powervalves and assembled




New seals went into the stator side, and counter shaft as well.


Wossner A Piston went on. Rings ends set at .35mm and .38mm.


And a single 0.5mm base gasket. Same as stock.


Also did a few other misc jobs. Cleaning gasket surfaces, nuts and bolts, and that kind of mundane stuff.

Next weeks adventures will include a squish test, and making sure the chasis is nice and clean ready to take the engine.

[Jakobi]

Shock is looking nice and clean ready to roll with its 5.4 rate spring also.

[Moto7man]

Very nice work.

[Jakobi]

No pics today. Didn't do much.

Ripped a quick squish sample to make sure all was well - and it was! Then slipped the head back on with 2 x fresh o-rings. Water jacket housing on. Nice gapped BR8ES plug on the ready.

Also pulled the brake pedal and disassembled. Both inner bearings are rooted and the seals aren't real good lookin either. Will be chasing some replacement at the local store next time I'm in - along with a load of other various bearings, seals and o-rings to add to the spares kit.

Nice Jake - this should be stickied as there might be more saps like me who are completely terrified of pulling that much of the engine apart and doing those maintenance bits.

I definitely appreciate all the pictures, even if it's tough to know what I'm looking at sometimes (lol).

Thanks again for taking the time to outline and detail the steps you're going through; it'll be a great reference for when I need to start in on all those things myself

[Jakobi]

In the engine section there are some similar threads I put together when setting the engine up from a 300 to 250, and again when I did my first bottom end rebuild.

When I started out here I didn't know a whole lot myself. Its good to give a little back.

[Jakobi]

Head and coolant housing back on.


Frame cleaned up ready for reinstall




Engine back in the frame


Note: Engine mounts installed but not tightened up. Will torque them up starting with the swingarm and moving my way forward.

[Jakobi]

Swimgarm back in place. New OEM chain slider installed.




Stator moved back into place and clutch area cleaned to be put back on.


Sprocket back on. I'll keep running the stock chain until this front is toast and then fit a fresh front sprocket and chain at the same time. The supersprox rear is still in great condition.




Note: still need to torque mounts and also the stator. Flywheel will go on too. threads on crank need a quick clean up.

[Jakobi]

Another quick note to self: stator, flywheel, and clutch piston all installed and torqued to spec.

Engine mounts still need to be snugged down.

Also ground down a new M6 bolt for the water pump housing. The old allen head got rounded out in a big way during removal. Gone to a traditional hex head. All cleaned up and ready for install.

Powervalve covers still need a small clean up before going back on, along with the stator cover.

This bike's starting to look good enough to sell!
