just finished my cam swap, my thoughts..
First and foremost a HUGE THANK YOU to Atrain68 and iclick. The cam swap threads you both did are what gave me the confidence to try this. Both of them also helped throughout the process through PM.
I'm not a mechanic, this is the first time I've done anything to the inside of ANY engine. I have changed the occasional water pump or alternator over the years,but that's it.
A couple of note... and DUH moments..
I decided, for financial reasons, to re-use the stock push rods. I've got an '08 RKC. The fuel tank quick disconnect is already there. Taking the tank off was SIMPLE.
I got lucky I guess. My exhaust was NOT the PITA most people say it is. My bike only has 8500 miles on it. (I bought it 4 months ago with 5k on it).
The biggest PITA to me was the PR covers. WHAT A PAIN!
There are several special tools involved in the process. All the ones I bought made that particular job MUCH easier.
I finally broke down and bought the long swivel socket to re-install the exhaust. I had to buy it on the internet, nobody local had one.
If you're going to go through the rocker boxes you'll need a small wrench called a "1/2 inch flank drive "dog bone" torque adapter. It's made by SNAP-ON and they REALLY think a lot of these litte wrenches. They wanted $30 each for them and you need two different sizes. I made my own by welding a old 3/8" drive socket to the middle of an old box end wrench. You don't need them for removal but in order to torque the bolts back down, you will.
The lifter holding magnets were great, I spent 30 minutes trying to bend the clip like they show in the manual and finally gave up.
I went with the auto zone loan a tool program to remove the bearings then used the old cams to install the new bearings. I used the SE bearings. They are much better than the stock ones.
I was really confused about the entire TDC thing. Turns out I didn't need to be. I ended up just watching the lifters as I rotated the rear wheel. I noted what they looked like at their lowest, set them there and installed the pr's. It was really that easy. As someone told me, as long as you can put the rocker plate back on and tighten down, they are at their lowest. (I may be simplifying this, if you're a mechanic, don't flame me too much)
The DUH moment was forgetting that I had to wait for the lifters to bleed down before they would "spin freely" as the service manual said.
Two scary moments. I finally got up the nerve to push the start button and it fired right up, then I see oil on the front cylinder pr cover. I thought it was leaking. Turns out it wasn't, I just hadn't wiped everything down well before firing it up.
The second, i thought I had an major exhaust leak where the rear header pipe connects to the rear exhaust. Turns out I put too much anti sieze on the connection and it was burning off.
I have a SEPRT. I downloaded the basic stage 1, 103 map. It seems to be doing fine, I'm going to probably mess with the "smart tune" over the next few days. I'm not worried about the numbers. The only tuning oddity is at idle. It seems to go back and forth from a very slow, lope to a fast warm up idle. I'm sure I'll figure it out.
Anyway, it sounds GREAT and in the very short test ride I got in, it is performing how I thought it would. Hopefully these thunderstorms will stop soon and I'll be able to get some serious riding in to make a better judgement. So far, I'd say it definately has more torque. (seat of the pants dyno;-)

You don't need to buy a torque adaptor if you have a set of box end wrenches and allen sockets in the size you need. Put the allen socket on your torque wrench, then your box end wrench goes on the allen socket. Keep it perpendicular and the torque values don't change. If you can't keep it at 90*, extend it in a straight line, and you'll have to use a formula to adjust the torque values.
