Cam/Lifters etc. Upgrade
Dropped my bike off at the shop yesterday. I originally wanted to have the lifters replaced with the newer style with the better bearing design, as it's an '89 with the original lifters, and replace the original cam bearing with a Torrington. That led to the idea of replacing the cam with an EV27 or the Woods equivalent. I had put it off until now, as the riding season is pretty much coming to a close here in New England, so I won't mind if the bike is in the shop for a couple of weeks.
When I got to the shop yesterday, the mechanic inspected the cylinder base gaskets with a flashlight, and pointed out that the rear cylinder is just beginning to leak. So while the bike is already torn down to do the cam/lifters, he's going to pull the jugs and replace the studs and cylinder base gaskets as well. I may have the heads milled while they're off as well.Should be rockin' come Spring.

RE: Cam/Lifters etc. Upgrade
Did the complete topend a couple of months ago on mine. I went with the VthunderEV5005 cam and lifters, adj.pushrods, 9.5to1 KB pistons and larger intake valves. I had the bottom of the jugs trued up to be sure I got a good base gasket seal. This combination make awesome torque. The cam is bigger than the EVL27 and a little noiser but I really like it.(569lift with236 duration) The intake timing makes a lot of cylinder preasure but I don't have any detonation problems. Last year I put aVThunderEV 3000 in whichhas very simular numbers as the EVL27 but I like this 5005 cam alot better.Put 2000 miles on before heading to Daytona for biketoberfest. Ran great, no problems.

You should always use new cylinder studs when taking apart the top end. The studs are stretched when properly torqued down and there's no guarantee they will retain the ability to be stretched properly when re-used.
As for new style lifters, I assume it's something like JIM'S big axle lifters?
