I have a '93 FLHS with 60 K miles. The top end was done about 16 K ago and bored .030" and currently the cam seals are leaking as well as the bottom of one of the jugs. None of the oil ends up on the floor though. The exhaust puffs smoke and I go through about a quart of oil in about 1500 to 2000 miles. I am thinking of putting an S&S 96" kit in it which has 10.2:1 compression. The guy that works on my bike says he won't do it because the bottom end won't hold up to the bigger cubes and more power. I have read that by increasing the stroke as with one of these kits it caused the piston to hit the cylinder at a sharper angle which causes a more frequent rebuild. I read it's about 35 K miles instead of 50 K miles. Does anyone have experience with this conversion and what are your thoughts about it? Thanks.:unsure
