1) Check out these pics of my engine internals:
http://chas.servehttp.com/bike
Is the black stuff on the top of the cylinder head normal? This was still when I was running <20:1, so I know the oil was building up. I am now running 40:1. Could the black stuff hurt performance? The engine seems a little less powerful than everyone here on the boards is talking, and I haven't noticed all that much of a performance improvement since I leaned out the oil.
2) I read somewhere about mixing r/c fuel (5-30% nitro in the r/c fuel) to the gas/oil fuel. Anyone tried this? Any info on that?
3) It seems that the choke can change a/f ratio a bit. if I am going up a hill at mid rpms, sometimes adding a bit of choke seems to richen up the bike and give it a little more grunt. But at wide open throttle, any choke hurts performance (i'm sure because of breathing issues). I HAVE played around with changing the a/f pin. When I set it for a good mixture at high rpm, it STILL seems like a little choke helps the engine in the midrange under heavy load. Any thoughts?
4) I read about getting a thicker ignition wire. Can I get any >7mm wire and screw it on? What about the coil pack? anything worth upgrading there? Or how about the spark plug boot? I have heard the type of spark plug doesn't really matter, so I'm not even going to open up that can of worms.
5) I have also heard there is a brand of oil that is formulated to be run at 100:1 in all engines. Does anyone know where to find this? I imagine as long as it lubricates like it should, that might help performance of the engine a bit.
My bike just seems to be a bit underpowered, so I'm trying to track down any possible source.
thanks in advance!
