okey well try to bare with me on this one. I got my bike back together finally and am now able to ride it (broken wrist), any ways. I had it ported/milled by mr.gorr and am having a few problems. This happened before i got my head back and still occours, oil leakes out from where the spark plug goes into the head...outta the threads,is this normal? And my jetting is way outta whack but thats another story :D. And in my manual it says to use a NGK R6918b-8 (<--- Say what?)...well i just use a B9ES...are these two the same thing? Thxs to those who help! :thumb:
