Default 103 Big Bore kit - Special tools???

Here's a question to whose who do their own wrenching. I want to install the 103 Big Bore kit on my 2008 Street Glide, and I'd take satisfaction in knowing I did it myself. I know that special tools are required (for removing the camshaft, for example), but how many? And are these readily available at the local HD dealer?

I'm assuming it's worthwhile running a different cam, and I heard good things about Andrews and the SE255 - does anyone have any thoughts on these. I'm looking for power above 2,500 rpm but without losing too much bottom end.

Any ideas and suggestions would be greatly appreciated. Thanks!

Hi,
Just thought i would let you know the book calls for a special toom to do the cams HOWEVER i did mine without this tool. The only thing it does is lines it up but you can do it with out the tool. the 255 cams do a great job hope you enjoy the power it is a night a day difference that you feel after the job is complete

I am having the dealer do my cams at the end of Janurary because they are having a sale and it's only $220 for the installation.
The cam's aren't a piece of cake to do and you do need several special tools to do it.
I figured it was worthwhile to have the dealer do the cams and in a couple of years I will put the 103 top end on, top ends are easy if you; once again a few specialty tools which I already own.

I JUST got done doing a 103 STG II on my 08 SG and did not have nor need any special tools for the install. The only "special" tool used was a torque wrench and a dryer vent hose clamp (Ring Compressor). Install took about 10hrs with some running around (needed loctite) and various other distractions.

I put on about 80 miles today without getting on it too hard but there is definitely more power there.

I did a 88" to 95". Heads, cams, pistons and jugs. The only special tool I used was a torque wrench and shop manual. I did improvise a couple of times, like a oak wedge to lock the cam gears when torquing and a jewelers screw driver to hold the adjusters away from the cam chain

Awesome answers so far! I especially like the "dryer vent hose clamp (Ring Compressor)" and "...a jewelers screw driver to hold the adjusters away from the cam chain" - that's true improvisation for you.

I've been doing a web search and it seems like there are a total of 5 or 6 special tools "officially needed", and they range in price upwards of $100. I'm all for improvising if it's possible.

UPDATE: I found this website for H-D dealers to order special tools. It's pretty useful as it has the tool part nos, illustration and description. I'm not sure if they'll sell to the general public of wrenchers, but it's worth a try if anyone needs that special tool.

I just did mine and the only special tools that are a must have are those green bills with old Bens picture on them. You won't regret it, and it's really not that hard, I have about 300 miles on mine so far and it's very strong and I know it's not tuned right yet.
