And check/change those lifters.
Have one coming in Saturday, with a lifter failure.
Hope for the clients sake, that it isn't as fugly as we have seen before.

I had the same issues with my 98 FLSTC. Opened up the breather, rejetted, added some VH long shots, a programmable ignition and an Andrews EV27 cam. Woke her right up.

 

I was shocked how much power I picked up from simply adjusting my throttle/idle cables following the svc manual (instead of just snugging them both up.)

Can anyone tell me how to identify what's already been done to my motor? I bought the bike with 60k miles and wasn't able to speak to the original owner. It seems to have decent power but I would love to have more (as always.) How can I tell if its had a new cam, lifters, re-jet, etc....? It has some obvious upgrades that have been done. It has cycle shack slip-ons, K&N filter, and a few more minor upgrades. The Push Rod covers look as if they might be aftermarket but I just don't have an eye for what the originals look like. The ignition module looks stock

92' FLHTC w/ CV carb and VOES

 

It sounds as if the PO might have done some mods to the bike. 3000 RPM @ 50MPH? I am doing at lest 60 @ 3000 and in cool weather 2800. Just a though but if the motor seems to run fine I would look at the primary and final gearing, may have been changed.
Cheers

 

There are two things that I would check before doing anything, first make sure you are getting full throttle, next do a compression test and a leak down. No sense putting pearls on a swine. If your compression is down and/or your rings, valves aren't in good shape then the benefits of the cam, etc will be diminished. once you do this then the help can be much more focused. Hope this helps.

Thanks for the pointers.

I've put about 4k miles on it with only minor problems which I've resolved. I've caught up all the maintenance and verified my compression is good. Are there any ways to inspect for an aftermarket cam? More importantly....it sounds like I need to make sure my lifters have been replaced. Are there ways to check for these 2 upgrades? Thanks for the help

 

The only way to tell for sure is to open her up and look.

 

I was affraid somebody would say that.....

 

Not sure if this will help you but when mine had the stock cam I had no acceleration on 5th gear.

If you want to pay the money you can dyno it and kinda guess what you would have to have in order to get the numbers that come up on the dyno.

Unfortunately the best way is still to open her up.

 

Just be aware that putting a cam in a high-mileage bike can increase your oil consumption due to the gum and varnish on the valve stem eating the valve guide oil seals....now would be a good job to do that top end refresh if fitting a cam....plus lifters of course.
