Evo build start up..
Hey guys, been a real help here lately so might as well ask my last question.
went to fire up the pig today, all excited and happy.. then nothing but whooshing coming from the bike.
Has to be valves opening, so I thought it was timing, but not wanting to hurt anything as I didn’t hear any metal contact on startup. I went back into the adjustable pushrods.
I set them as usual, but remembered that this pig has compression releases. I recall hearing of a different method to install rods with releases, but don’t remember exactly how?
any truth to this? I readjusted the front using the flyweel peep hole and made sure it was Tdc compression and made sure the rear is tdc. I possibly was off tdc a bit first go around, but that never was an issue before.
also, I’m running a wood 8 hi lift cam and was also wondering if the ss rods still require 4 full turns?
so really it comes down to compression releases, pushrod turns or timing.
any help is appreciated gentlemen!

I take it the wooosh your hearing is lack of compression... Timing and compression releases ain't gonna do it. Most likely the valves didn't bleed down or you set them to deep... ALWAYS TURN THE MOTOR OVER BY HAND AFTER ADJUSTING THE PRELOAD ON THE VALVES... ALWAYS.... Set to .140"...

Compression releases have nothing to do with your pushrod adjustment. Two different animals. That only comes into play on a Twincam when using S&s cams with built in compression releases
