Default 103" cam swap

Just put some cams in my bike. Engine starts up sounds good then once it warms up and I turn it off start it again it doesn't wanna run just sputters and dies. The bike has a screamin eagle computer already and was tuned when it was just pipe and intake I'm assuming it just needs a tune but wanna make sure that's what it is. Iined up all the timing marks good and it starts right up doesn't pop or anything like that. What you guys think? Thanks

Lol how much more info do you need? What do you want all the cam specs step by step install notes, it's a simple question besides cam timing and tune what else could cause it? I'm assuming nothing because no electrical components were removed besides plug wires one piece pushrods were used to eliminate the adjustable junk failing or not being set to the right length. There's not much else it's not like cam swaps are a hard venture. It's the computer crap I'm not familiar with

Once you swap cams, you must do a tune preferably on the dyno for best results. Just did the same & my bike runs like a Patek-Phillipe watch.

What cams did you use? Sounds like a timing issue to me....

I'm no expert. But there are some on this forum who are. And I know they can only help when there's enough information given. Like what year and model bike. Which SE tuner. What maps are loaded. What pipes/cleaner. Which cam. And anything else pertinent.

After making a cam change you definitely have to re-map the bike. Not doing so can damage the motor if you're running to lean.

interesting , that the adjustable pushrods are "junk"
and the computer is "crap"


how do you compensate for the cam grind with solid pushrods? I believe you need to adjust the pushrods to the cam/lifters
sounds to me like the lifters are pumping up and now wont run when hot .
After it "cools down ,and the lifters collapse then it runs ?


the fuel map that was in the "Crap" computer will run the bike .
It may not be the right mixture for the new "cams", but it will be consistent , not run some times ,sometimes not


Who did the cam swap?
