got a little over 1000 miles under my belt and love my 05 F4i. Rebuilt it over the winter. The only issue im having now is a spongy brake lever. Its always when i first get on the bike. Once she has warmed up and i have ridden for a bit the lever gets pretty tight. It sometimes sticks and i dont notice till i pull in the clutch and feel it slightly grabbing. I am constantly pushing it out. I have some pretty cheap carbon fiber levers off of ebay on her right now. I have already blead the brakes and am pretty sure i did it right. it just seems like for the bike, i have to warm up the brakes as you would warm up your tires. any ideas?

 

You'll probably need to overhaul your calipers as they might be sticking due to the acumulated crap. Mine did...

Bleeding only willl not solve your sticking problem.
