An update on my 620


Recommended Posts

I decided to really tear into my dcnf and get the jets it has been needing. I bought a air cleaner that is solid aluminum. I am now running a 165 air corrector, down from a 185, and a 190 main, down from a 230. Wow is it quick. It pulls much harder at 5800 than before. I cannot wait until I can advance a bit more timing. Right now I am running around 22 deg full advance. I should be able to get away with 28 to 30. I had to learn the hard way what too much timing does to a LZ22, so I will have to be careful. Last time I broke a piston skirt.
