Those four screw go all the way in and stop when they don’t turn anymore.

Not's not how it was with my situation. My cage wouldn't even move. I had to back the screws out a little to get the spring action back.

Those screws are shoulder screws and have a torx head. T15 or 20. They stop when tight. There is a spring on each between the horn depress and a plastic collar. That is the only moving part in the horn. If the bottom copper piece isn’t seated the correct way it will make contact with the horn.

this is how my wheel was assembled when I swapped the wheel.

Took valve covers off. Broken exhaust valve spring. And broke the wire to inspect plugs. Just gonna replace wires and plugs while I’m at it. I’m guessing I have the outdated valve cover. What do you guys suggest on what valve springs to replace and plugs.

Also any suggestions on how to replace them. Gonna research YouTube and such. Any tools to make it better, whatever info you got is appreciated.

Oh shit! You just replacing the springs or what is the plan there?

How many miles on her?

Your plugs look pretty damn good compared to mine.



Yeah I hate that ******* piece that breaks off when you remove the spark plug wires. I just did mine and half of them broke like that.

Let's see a pic with the rim on dawg.

lol I just took the big wheels off for winter and put stock ppv wheels on with 33s.

So do those red calipers add 10hp or 40hp since there's four?

15hp each so 60hp.

Seems better than originally thought! Have you been able to endoscope the cylinder to make sure there's no debris?
