Thanks to RFM I got some new shiny parts in the mail today. In preparation for the final putting together ceremony I thought I would do a few things first while I have the bike torn down.

Service the airbox
Make sure the spark plugs were new
Finish the carbon canister removal process
Lubricate the throttle body linkage
Clean up around the engine and frame
And just check things out in general

And it's a good thing I did.

Step 1: Remove airbox and CAREFULLY remove the airfilter making sure nothing drops in the throttle body.

Clean up the Evo Velocity Stacks that RFm kicked down and install them in the bottom airbox housing thing.

I can feel the power already.

Now to clean up around the throttle bodies and spray some silicone lubricant on the linkage to make it feel like new. The throttle definitely feels better now. You can't have a 20K mile bike and not do this stuff.

I also plugged off the last of the nipples that fed air into the charcoal canister emissions circuit. Safety wire will do a great job in this case.

While I had the airbox off I went ahead and cleaned things up around the engine. Then I took the sparkplugs out just to make sure they were in top condition. Things look good so back together everything went. NOTICE THE TAPE OVER THE THROTTLE BODIES - HIGHLY RECOMMENDED YOU PUT TAKE ON THEM WHILE YOU WORK.

Time to button things up now. Velocity stacks looking good too. Like my modified oil catcher? It should hold 3x the oil overflow as the stock. Plus it's a lot easier to see now.
