Was there any damage anywhere else in the engine?

doesnt appear to be, pulled the rest of it all apart last night. everything appears to be in order... and if the rod didnt swing around and smash the skirt on bottom of the piston i would only need another rod...

pitty as motor still had abit of compression, not that it ever had the 'nip' at the top of a nova motor even when brand new out of the box.

now i need a new p/l & rod set, cranks fine bearings are all fine and shrapnell now removed.

Default Murnan Mega/Picco 12

Just some shots of my Murnan Mega/Picco 12. I'm still breaking it in. I've got 10 tanks though it and it is already screaming. It idles very smooth and it seems to be strong throughout the powerband. I highly recommend a Murnan to all seeking exceptional performance. Enjoy

thanks,
tabushi, a friend of mine got the same problem, he found out that the conrod bushing was tearing apart and that is why he burned plugs as hell, too bad he realized that when the engine began to make an awful noise. the lower bushing in the conrod gave up and the pl was scratched, runnin time one gallon, running in per manua, stiil the conrod gave up
check engine!

Managed to finally run my MEGA after a thorough check on the carbs and internals. During the break in period i found the spring on the idle screw to be loose and tightens itself when you rev it. Easy fix by pulling the tension on the small spring to make it stiffer and a drop of thread lock on the needle to leave some residue so it's not so loose. What i found surprising was the difference in tuning compared to a NovaRossi based engine which we're used to running here in Asia. I had to richen the low end needle to a point where the screw was jutting out almost 2mm. This beast has got loads of torque. I run a 710 and had to screw the Centax tension to 2mm(Centax2 spring) from the normal 1mm i'm used to. Boy, what a difference it made. The car came alive almost immedietly.

Most of you must've had the o ring problems with the low end needle. I had a local modder remove them and sand the gap for the o ring a little bigger and replaced it with NovaRossi o-rings. No more issues there.
