Pushrod issues bent or incorrectly placed - damage?
Hi, can anyone help? I replaced my rocker cover gaskets recently and once all was closed the motor runs extremely rough. Carburation is great and timing seems good.
It is a 2002 883 XL Sportster.
If I got the inlet and exhaust pushrods swopped would this cause damage and rough running?
Can I correct my mistake and just swop them back?
Due to not putting the rear cylinder at TDC would this lead to a bent pushrod or valve?? The exhaust valve was full open when I replaced the rocker assembly. There is no compression in the rocker cover so the valves areclosing fine. There isn't any smoking either.
Remember that the timing etc.. was not touched. Only the gaskets replaced.
I had to remove the pushrods to remove the rocker assembly.
I am after some real replies folks. I am in South Africa and the parts are hard to come by here. (can wait up to 2 months for parts.)
The motor still runs well but the sound is off. Fires first time etc.... just sounds slightly wrong.
Any help would be appreciated!

Well doggone Hex.
You are just going to have to set this thing down and, "with a manual or proper directions,"redo what needs to be done. I don't know with an XL but proper is proper and must be done right. There are issues with the proper way to set and adjust pushrods on most all engines. Find out and do this again.
Breaking things cost you money and also you might break down somewhere inapproiately. Like anywhere except your place.
AlPlenty of sites have things like how to adjust set and adjust pushrods. Check out NRHS Preformance. They work with a lot of XL's
Good Luck

RE: Pushrod issues bent or incorrectly placed - damage?
If your engine has the non-adjustable pushrods you could have mixed them up. I'm not sure if the Sporty's are like this, but sometimes the exhaust and intake pushrods are of different lengths. Doc1 or ShovelheadBob might be able to help with this. I'm not sure if it would bend a valve or cause a valve to crash on top of the piston. I don't think the length difference would be that great.

Thank you to the guys who answered!
I had the guys from NRHS racing give me some info as well and it appears as meticulous as I was I may have gotten the pushrods turned around anyway.
I will open the motor this weekend and do the checks and swop around if that is the mistake.
These motors are tough and I hope the pushrods being swopped around won't cause damage.
I will post my findings on Monday.
Thanks for your support.
