bike has 28,000 miles on it, and sat for an unknown time when purchased ("not running")
Now here is where the fun begins, ive never been able to figure out why the bike runs just fine at rpm above 4k but it cant idle correctly....
Anyways ill go through how i figured this out...
Cleaned the carb (got high end perforance back)
Changed spark plugs(more high end)
Checked grounds (actually got it to idle for a time, probably not related)
Random symptom bike burns oil when coming to a stop at a light from the cylinder with 0 compression
After i ran out of things to check i pulled out my compression tester, cylinder 1 has 120psi compressoin and cylinder 2 has 0 psi compression
Anyways ill cut to the chase, what are the common causes of 0 compression in these bikes?
My guesses so far
Burnt Valve, Valve not closing or not sealing properly
Burnt Piston, or warped cylinder
And also what does a rebuild cost if i were to do it myself over a weekend? And what should i buy and lookout for
Edit: On the cylinder with 0 compression i can feel air rushing out of the spark plug hole, however with the compression tester on it i go to 0, (i can conclude the air is going elsewhere but not sure where)
