Polishing intake manifolds
in General Tech Discussion
6 years ago
I removed intake manifolds from ULS engine. Planning to replace old balancing tube with 1" line.
When I looked inside of them, found pretty rough surface. Normal for aluminum castings.
In my early motorcycles days, we used to polished intake on 2-stroke engines with pretty good results.
Will it be beneficial to do it on 912 engine?Do we know for sure that ports on intake manifolds lining up perfectly with head ports on Rotax 912? Did anybody ever checked that?
