Chinese MS440, New west big bore.
Timed it at 103/120/64 without base gasket,
Squish at .016”.
Running in video with .020” gasket.
Definitely needs more intake.
Band is good and wide, compression feels stout.
There’s potential here for sure.
Going to come apart for porting after some run time.
Eggselent Dave.More intake, a lot more, only change.
It hasn’t been. China muffler is not very restrictive.Eggselent Dave.
This is the kinda thing we all learn from. I thought more intake created less low end grunt? Guess nawt.
I assume it’s been muff modded?
Did it come with the dp cover?
Well did you say yes sir or yeah sure?Yes sir yeah sure
