Re: machine new cylinder?
Actually, I've been waiting for someone to come up with this. There are lots of different kinds of billet cylinder heads, and i have been wondering why is it that nobody has ever thought of a steel sleeved cylinder for the HT. I guess my wait won't be long now. I'm really excited to see the results of this project. Most of my engine that failed, was because of this, and secondly the wrist pin bearings. Currently, i'm using needle bearings from a chainsaw and seems to be ok. Actually, in my engine i sanded down or polished the edges of my piston rings so that the wear on the cylinder lining would not be as great as it was. Seems to be working. I also think that the carbon build up also contributes a lot on wear of the lining. So decarbonizing is highly recommended.
Regardless if it's left or wrong, the opposite is always right.
