A few weeks ago I upgraded to a 4.2. With my previous 4.1 I ran the out of the box setup no mods or upgrades and was happy with it. I built the 4.2 to the stock setup and it is waaaaaay to twitchy. Basicly the only difference between the two are the big bores and the alum steering rack. The 4.1 was over a yr old but well maintained with regular parts replaced so it had very little slop. Does anyone prefer the plastic steering\savor over the alum?
