++Athena 290 KIT INSTALLED

I can be most easily found at :

or

Here's the kit I got : it will work on 08-11' 250R and X : http://amzn.to/LLZq4y <--- It includes everything you need for the upgrade. Have fun with your extra braaaap!



So my friend Jason and I just put Athena's in both our 2008WR's yesterday ( video of install coming soon ).

I used the MAP off dyojets site as I'm using the USBIII fuel management instead of the Athena's + - the gray wire thingy : )

I'm looking to get the best map installed for the following configuration. Any insight into this would be greatly appreciated as I feel the bike could definitely be refined. As is she's got some pretty nice braaaaapability!

Current config:
2008 WR250R
-Athena 290cc kit
-Yoshimura RS2 Exhaust
-FMF Megabomb header
-Flapper removed
-Dynojet USBIII fuel management
-other farkle goes here.

Much love in advance for your insights ; )

Outstanding!

Love the videos by the way. Particularly the one where your slogging through those massive mud puddles.
I subscribed shortly thereafter.

It's fantastic!

My Problem: The more I read, the more I want. So I'm considering the Athena kit now.
My Experience: I've rebuilt the top end of an inline-4 motor before, but that was when everything was OEM.
My Question: Is the Big Bore kit something that can be installed without any specialized tools? Or does it require odd machinery to install (ie piston ring compression sleeve, honing tools, etc.)

You will need a torque wrench. While you're in there, you might as well check the valve clearance, so a decent feeler gauge set will be necessary, as well as access to the shims you might need.

I installed the piston/rings and cylinder on mine, by myself, without the use of a ring compressor. It wasn't hard. Getting the wrist pin circlips on was a bitch, however. The cam chain tensioner can be equally frustrating.

if you're not mechanically inclined, don't have the room or want the peace of mind, get it done by a reputable shop....they would be on the hook if anything happened...I did one with all the tools and a motorcycle lift in 4 hours.....cams/chain were a bitch...

I'm pretty sure I wouldn't pull it off in 4 hours but I'm confident that I could do it. I guess my question was more to clarify if specialty tools were needed relating to our specific bike, or if not using them caused serious headache. Now to find a way to funnel $1000 without the wife noticing. Is there a forum topic for that? Because if there is, I HIGHLY recommend it be stuck to the top!

I started a separate account and have certain % of my paycheck deposited directly to that account. She knows the account is there but doesn't know how much is in it or what I spend it on.

She has a similar account.

Before these accounts, we were constantly at each other about spending on stupid shit.

That said, just dropped nearly $600 on a new Lynx fairing and she's not pissed :)

Unfortunately that isn't going to work in my situation. Cash is the easiest to make dissapear but is also problematic as I can't use it when ordering online. Anyways, we're really getting off-topic now.

So how 'bout that Athena kit?!?!

I have a bunch of video footage of the swap, it's not a highly detailed step-by-step but does capture one of the most important parts of the workflow ( The cam chain tensioner ).

Perhaps I should post it : )

Next farkle needs to be a turbo. All else is pretending.

Yeah you should post the video of the little WRR's engine rebirth in all it's glory!

Do it now or there will be more of these

How did the piston compare to the stocker? is the skirt shorter? I might look at either this or the 280 kit in a few years when I need to do a top end. The 280 kit wouldn't be much more expensive than replating.

Finish putting mine in last night.

The Mod is well worth it.

The torque that the BB kit gives you its what the WR really needed.

Tips:

-Make sure to check your valve clearances (one of the exhaust shims was seated at a angle and the bike wouldn't start. Would have saved me hours of troubleshooting)

-Compressing Chain Tensioner ( The best way to get it down and locked and ready is to get a piece of sand paper fold in half on a table and place the tensioner on top of it and with a back of a screwdriver handle push down on the tensioner and spin the tensioner with your other hand)

-Releasing Chain Tensioner (once everything is lined up use your hands to press firmly on top of your chain in the center of the cam gears with your index finger and pinky finger spread out (reverse Spock hand sign) and rotate slowly counterclockwise. Make sure to focus and keeping that pressure down than rotating. Rotate twice before releasing your hand off the chain and when you feel the tensioner release DON'T remove your hands keep rotating. Also use a latex glove, it helps with chain slip through your hands while you rotate.

I'm getting an Athena kit in today.
Pulled the bike down last night.
Lots of stuff in the way of the head/cylinder, wire loom, tubes, cables.
Those aren't a problem.

Do you remove the airbox, and if not, how do you get the throttle body out?
Just disconnect the rubbers and pull it up through the frame.
Doesn't seem to be much room in there...

You don't remove the throttle body or the airbox.

You just need to loosen the hose clamp on the engine side of the intake and when you pull the engine you tilt it forward.

...egads, didn't know you had to pull the motor.
For real?...

You don't have to pull the motor out but its alot easier with it out. Just to loosen the motor enough to work on it isn't too far from pulling the motor out completely.

...easier to unbolt the front down tubes then?

-Remove all plastics
-gas tank
-igntion coil & wires
-remove brake lever
-vent tube for valve cover
-left side wire harness (next to coolant bottle)
-remove front tube bolts
-remove exhaust
-remove starter
-remove clutch cable
-coolant hose
-loosen (to work on bike) or remove (to work on bench) swing arm bolt
-remove engine
-have a beer


i'm sure i'm forgetting somethings but thats basically it.

I would not remove the engine. It's not needed.. Tilting the engine forward however, is.

Took 3hrs with two guys, start to finish.
