(silverfreak @ Apr. 21 2007,05:12) sounds like you have a hairline crack in the #2 cylinder wall.it leaks when it heats up and.i had this happen on a 2005 gsxr 1000.went in and put higher compression pistons in and it had coolant in the #3 cyl when i pulled it apart.thought it just got in when i pulled the head off.put the engine back together and 20 miles and had a leak.the crack was very hard to see.had to have a magnifying glass to find it.might try that. good luck
