So did you put on one of Alex's ignitions? Did you use a stock base gasket or change the jug height? I'm assuming the squish was modified. Will you be running on race gas? What's the deck height?
yes he runs a MZB ignition. with the optional lighter flywheel.
Running 2 .020" cometic base gaskets for a total of .040" not to raise port time (by product) but because his stacking tolerances needed it for piston to head clearance reasons. (more info on that in his first motor build thread).
Head info is as follows.
13:1 ish compression (un corrected). 42cc head volume. .010 head gasket. .0145" piston in hole
Squish clearance: .044"
88mm width
.48mm head step
4deg cut for 4.89mm to 15deg for 9.66mm
total squish width (measured straight instead of cuts) 14mm from edge till you hit bowl edge
Motor will be run on 25% 100LL avgas and rest 91octane pump fuel. ONLY because our California fuel SUCKS. the bike would tolerate just 91 pump fuel (except for maby in the dunes)
