I bought a tri-z side case off e-bay and i noticed it had a big hole in the case from the tranny to the kick start
the guy wrote this back
"The case is good. The hole was to oil the kick start gear better. We raced these in the day and figured this out. We use to driil them but figured out it was easyer to just punch a hole in them. The zss were notorious for not getting enough oil to the kicker."
The more I look at it, it looks like it was punched in the only place it could be and it kinda makes sense.
Anyone know if this really was a common mod done to the Z's?
