Cam replacement
I am thinking of replacing my stock cams with gear drive.
My bike is stock with the carb jetted, K@N, Vance and Hines true duels and Hooker Tunable Slip-on exhaust.
Is this something I should attempt myself? I have a air lift and alot of tools and service manual for my bike. I am confident and have done alot of other service work like bars, wheels, brakes, carb jetting, but never anything like cam work.
Just want to know if I am setting myself up for disaster!!!!!!!
Any imput appreciated. [sm=patriot.gif]

RE: Cam replacement
The conversion is a detailed task. There is nothing that will jump out and bite you.
The factory service manual will help you get things apart and back together. S&S, Andrews and Crane cams all come with detailed instructions for installing the gear set. There are tools available to rent that will help you get the job done right. If you decide this is a project you want to tackle, there are folks here that can help you every step of the way.

RE: Cam replacement
Grover,
Thanks for the input.
I just got off the phone with my mechanic friend that recomends the S&S 510G kit and also S&S adjustable push rods.
Heard anything bad about them?
I had thought about Andrews before he mentioned the S&S.

RE: Cam replacement
As long as you have the svc manual (which you do), tools, and are fairly machanically inclined, it's pretty simply and straight forward.
510's are nice cams for generally stock motors. Do NOT exceed 9.7:1 CR, or your engine WILL ping. Stock is much lower so, you'll be fine. The 510's actually "like" just a bit more than stock compression (again, up to 9.7:1).
Andews 26G's are comperable, but they come on just a little earlier and do not like anything more than about 9.25:1 (some will tell ya 9.4:1, but you're flirting with pinging at that point).
A third option might be Kuryakyn 1G or possibly 2G cams. There have been some really impressive dyno charts posted using these on stock motors. One benefit to these is that they seem to like as much compression as you can throw at them and "supposedly" do not have starting and/or pinging problems.
In all cases, an engine needs to be "properly setup" (compression ratio, squish, etc.), and some cams are forgiving than others, so.... it probably depends most on your personal goals for the build - both now and down the road....
Good luck!

RE: Cam replacement
I'm in the same boat here - having worked at a dealership now for about 7 weeks and having seen a tear down, it really looks quite doable for the average backyard mechanic. I'd also like to do a gear drive setup, so, let's keep in touch and see what cam most of the members like. Remember, no other mods except the cam (and adj pushrods) at this stage will make a difference in what we select.

RE: Cam replacement
It's a very easy job, if you can read and have a decent set of tools. You will need to get the specialtity tools for the job. I rented them.
