Engine Upgrade Advice
I ride a 2007 Road King with approx.52,000 on it,last Winter I upgraded cams (andrews 48h) which improved the power and torque.Now,I am wanting to add 103 cylinders,and possibly more cam such as cyclerama 575,or something similiar.
My question is is the miles on my engine too many for these upgrades? Engine is very sound,and runs well,already have s&s aircleaner,brocks 2 into 1 exhaust,and I run an FP3 tuner...thanks in advance!

If it was my money I would start fresh with a complete build bottom up. 50k ain't really that many miles if you have taken care of your bike . I would also call some of the companies that provide excellent products( theres a few on this forum) . I wish I would have built my bottom end to withstand any future builds.

Personally, if you are messing around with 103 and more cam/heads, I'd want my runout checked to make sure the foundation is okay. Granted, this comes from someone who had their crank prepped with doing a build.
Just a warning, chit gets spendy real fast.

You might as well go to 107" if you are going to be buying pistons and paying to bore a set of stock seasoned cylinders. I agree without doing headwork the cam change wouldn't give much return. I would use the cam money toward a GOOD tuner and dyno tune...

Thanks for all the replies,and advice,I failed to mention that I am on a tight budget,and cant afford a bunch of $$$ for big bore kits.A friend has offered me his takeoff 103 cylinders,and pistons that have low miles ,and have considered installing them along with the.030 head gaskets to bump up the compression a bit,followed by the 575 cam.
No,I did not check the run out of the crank when I installed the cams-it never crossed my mind to.

Exactly. Or just keep his 48 cam as it's right in the same ballpark as the 570. I wouldn't waste the $ on a cam that you'll barely notice the difference if all things are equal.

Again check your run out first.
