After sending frame i have found 2 problems.
I would like to clean and flush that part of frame wchich holds oil, what can i use fir that, normal engine cleaning stuff or may be there is some special cover inside and i should be carrefull with that?
2. I have found that the guy who did sending did not cover small holes in the frame where water shoud go out if needed. As a result i have some send on the frame, hiw can i remove that?
