Jake's site is down it seems, so I am going to ask this here.
I am about to set my pushrod geometry, but I am having a brain fart. Do I use the peak cam lift or the peak valve lift. I think that it has to be within 5% of peak valve lift, but I am just not sure, and I don't want to mess it up. Also, does anyone have a copy of Jakes article for setting geometry? I pretty much remember the procedure, but I'd like to re-read it before I continue to make sure I have it right. Zach |

That is a good picture. I think the adjuster in that picture could be straighter or more inline with the valve stem. Also the rocker could be moved to it's left a little. The idea is to only have the adjuster working across as close to center as possible. If the adjuster is all the way up in the rocker arm the rocker arm needs to be raised to get the adjuster straighter. Close isn't really part of the procedure it needs to be right. Don't get in a hurry there is no rush it isn't easy but once it's right the guides will last a long time.
