I have a 2.0L motor sitting around that was water siexed (rusted) ao this weekend I pulled it apart.
Needs new pistons and cylinders so I was looking at this big bore (no machining needed) kit. Anyone have experience with this particular kit? http://aapistons.com/index.php?main_page=p...;products_id=58 |

One other thing I forgot to mention. Deck height was a bit high on these. With no base gaske or head gasket I got .068 of deck height. That was more than what I wanted but with the 50 CC heads and my 1911 cc displacement I ended with 8.6 compression ratio which is right where I wanted.
If I was building it again I would have had the base trimmed and targeted closer to a .040 deck height and had the heads worked to have a slightly larger chamber and kept the compression ratio about the same. But all that costs $$ and I have already said I'm a cheap bastard! The engine was not hard to tune but I can smell a very slightly rich mixture at idle. If I jet down the idles I get occasional lean pops just before transitioning to the mains. Stick with .050's and it transitions fine. Dial in the idle screws so I don't smell the exhaust and I get light popping on deceleration. So I just deal with a slightly rich mixture at idle possibly due to incomplete combustion from the larger deck height. Overall, plugs look great and overall the engine runs excellent! |
