Hi,<br /><br />I bought a spark tester today to help start the diagnosis of this beast.So far tonight I have found that the top two cylinders have no spark at all. I doubted the problem was coil, but i moved a known good one to one of the top cylinders and it was still dead. Where is a good place to start here ? switchbox, stator , trigger ....? are any of these divided in two with respect to supporting a pair of cylinders ? Just seems funny that its the top two. The other two have good strong spark.<br /><br />thanks in advance,<br /><br />Paul
