Im kind of running out of ideas.
Pistons and all are fine rings go in all the way when fully compressed.
I find it odd that only cylinder 4 did it this time.
Forst time it broke all 4 only top rings which make me think its detonation when this happened i had a weber down draught carburetor on it (34ADM)
Now i have cbr1100 38mm mikuni bike carbs and i have only broken number 4.
But I am starting to wajder if itsnrunning to lean. I will obviosly have to hook up a wide band to verify.
Also there is no damage to pistons at all and all look very good woth no signs of detonation.
