Project CBR600F: Code Name LOL (Lots of Leaks)

Armed with jugs of oil, coolant, fresh gasoline and an inexpensive gel battery from Amazon, I was excited and slightly nervous about pressing the go button.

Battery installed!  Key turned!  Rear brake light check, good!  Front brake light check, uh-oh.  Right, we'll fix that later.  I pulled the tank, popped the radiator cap and started filling it with tasty coolant.  When I went to give the hoses a squeeze to help burp the system, I heard *drip* *drip* *drip*.  Oh no.  I spotted 3 coolant leaks.

That's one crunchy o-ring in there.

Ok, well, I was expecting leaks just not from those places.  While I was out there, I might as well fill the oil.  The K&N filter looks new and the existing oil not too shabby, so I topped it off. I returned to the house for some snacks and to track down the o-rings and hoses. 

I returned later to tackle that brake light issue.  I removed the switch and disassembled it.  It looked good and tested fine.  The wires were good, I completed the circuit and the brake light came on.  Hmmm.  I cleaned up the contacts and reinstalled the switch.  Much success!  

But wait.... why is that bowl I'm using to catch coolant so dark?  

That almost looks like...oil.  Oh no. Immediately my brain goes into panic mode!  Oil in the coolant! The end is near! But wait...that's not possible.  I didn't test start the bike, it has to be leaking from somewhere.  

Yup. Another leak.

This time, it was from the pulse generator cover.  That gasket is made from unobtainium, so I'll be rocking the ULTRA BLACK RTV gasket.  Whatever works.  

So, a few steps forward, a few back.  More reasons why I prefer air-cooled bikes.  The o-rings are on order and I'll have to figure out a universal application for the rad hose, thankfully it's not to fancy with bends. 

Stay tuned! We'll get to that magical first start eventually.
