When talking about shims, it is always reffered to the total amount of head clearance.
Running 25% Tornado Fuel with Ninja Pipe. Currently running 0.4mm shim thickness and have a head clearance of 0.95mm.I used a solder lead and turn the flywheel over to get the 0.95mm clearance after measuring the squeeze solder lead.Am I doing it right?
0.95 is to much, your engine probably doesn't have a lot of bottom power.....
Run the engine with an head clearance between 0.6 - 0.7mm
Measuring with solder is a possibility, I always do it this way. (if possible due to the engine's pinch)
Take out your plug, rotate the flywheel until your piston is in TDC.
Unscrew the engines head and burnroom.
Measure the distance between top of piston and top of liner.
Make the same measurement for your burnroom (without any shim)
Now you know the headclearance your engine has, without any shims installed.
(should be 0.55mm, concluded from your story)
