PUSH ROD ISSUES
99 80 inch softail,,,
started with an oil leak on the front cylinder at the base of the rocker box on valve side,,,, removed rocker box,,, gasket blown on front edge right off front bolt of valve chamber,,, bolt broken,, extracted bolt no problem no damage,,,, replaced gaskets, pushrods checked (not bent and have proper play when lifters bleed down)and back into proper place,(bike ran fine before take off),, didnt remove jug,,, didnt remove carb,, did all in the bike,,, I have a velocity stack with joker breathers,,, after install,,, no idle,, but starts right up and dies,, pushing air out of breather on that cylinder and puffs out carb,,, got fuel,,, nothing changed, valves seem to open and close with no problems,,,,, i have gone back three times and rechecked and even replaced with different gaskets, proper torque specs any ideas as to what the hell is going on here,,,, any help would be greatly appreciated... I have installed new plugs,wires,coil before this repair,,, checked plugs they are good,,,,, an after thought tells me that possibly someone has been here before and the pushrods color coded yellow to intake and green to exhaust might have been switched at some point and time,, does any know whether the longer of the two push rods goes to exhaust or intake?[/align]

rear exhaust: purple
rear intake: blue
front intake: yellow
front exhaust: green
Whan all else fails cut them out with bolt cutters so you dont have to take the heads offand install a set of aftermafket rods that can be adjusted.

RE: PUSH ROD ISSUES
Any popping when you rev it up? I would take a good look at the head, do you have a burned valve or a cracked head? how is all that compression getting back in to the head ask your self? what seals the compression in the head?, only a couple parts could have failed..
The head could have cracked into the bolt hole?
Did you check the mating surfaces with a straight edgeto make sure they are straight?
Wish I lived close I love digging in to engines...

From the front exhaust that the nose of the bike is the longest push rod and then it goes to the intake intake exhaust which is the back of the bike is the shortest push rod so it goes from long to Short front to back if they're factory push rods and

Front exhaust longest rod then it goes to intake intake in rear exhaust shortest rod hopefully that helps this is for factory unadjustable push rods

Good thing this is a thread that has been dormant for 16 years, because your explanation makes no sense.

For anyone who came here looking for the correct positions of Evo pushrods:
Longest pushrod, front exhaust.
Next longest pushrod, rear exhaust.
Nest longest, front intake.
Shortest pushrod, rear intake
Longest pushrod, front exhaust.
Next longest pushrod, rear exhaust.
Nest longest, front intake.
Shortest pushrod, rear intake
