Lectrons tuning

[grantevans713]

Recently put 38mm lectrons on my 421 with assassin cylinders. Took the bike out to the dunes, put fresh plugs in it and went to ride to get a feel for where it was. It seemed to be running good, no hanging on idle, snappy response, decent sound. I was headed back to check plugs after about 5mins of riding and bike died. Something fucked up and cylinders fucked on one side.

 

What are y'all running your lectrons at? They sent me 4-2 metering rods, but their tuning website says up to 330cc with it. Should I grab like a 6-3 metering rod or just adjust the one they sent? I didn't get a chance to really inspect plugs, the one side had the dreaded concrete color. Can't tune with the engine out and cylinders shipped off for a resleave, just trying to get everything together so I can ride and time when it's back together.
