A few lives left. I've been thinking about v5 for a while, but no definite plans yet.
How about we just got to V.4.5.1?
Upgrade cooling, polish, knife edged and balance the crank, "hot" cams, re-route and clean up some of the spaghetti mess 'o cables up front....
Ok, maybe not the high $$$ upgrades, but the simple stuff.
