Hey guys,
Been working on a 78 cb400t for awhile no, resto mod. Getting a fresh top end tuned in with some VM30s, UNI pods, Stainless 2 into 1 exhaust.
I am getting close with the VM30's, current setup:
slow jet: 35
Needle: 64F 2nd from top
Slide: 3.0
Main: 140
Air: 1.75 out
Slightly lean up top, rich at idle. Have 145s on order.
However, while I was doing plug chops I noticed some wet plugs coming out. This happened after I adjusted valves. They were bad. I adjusted during motor assembly per FSM but this is the first time after really riding the motor. So I am assuming this boosted the chamber pressure to the point that is is starting to really test the rings. Here is my plan to trouble shoot and I would like some input from the forum on anything to look out for.
compression test.
oil in chamber compression test.
Leak Down test.
I will report back this afternoon with results.
Here are some pics. Trying to do a scrambler type build. I was humbled in my my first stainless exhaust attempt, love it but can't wait to do another to make it better. See ya in a few hours.
