were does the larger of the 2 washers go? Im pretty sure i have them assembled correctly, im not sure where the larger washer goes? Im guessing at the base before the white base seal goes on but whats the point as the washer is the same size as the base flange.   | ||

Yea, pretty sure those drop in on top of the lifter guide, against the shoulder. Then the bottom seal rides against that. | ||

If this is a set of zippers then the big o rings fit in the base of the billet base against the motor to provide a seal between the motor and the base, then the white one fits in the base of the tube like you have pictured. I did a write-up on this when I installed these on my s3t and on my s 2 project. I used the kit from zippers and purchased through NRHS. | ||

Ooooh. those are like from the future. My ironhead uses cork washers. (In other words, I am of no use to you sorry.) | ||

lol- got them all together and installed. Ready to put the pushrods and rocker boxes back on. | ||

I too just did this job. Check out Jolly's write up on it. It is spot on. | ||

TELESCOPING PUSH ROD COVERS are a good PRODUCT IMPROVEMENT !!! "BUT" replacing the LIGHT OEM PUSH RODS with "HEAVER ADJUSTABLE PUSH RODS is "NOT" !!! | ||

If the telescopic covers are aluminum, I would expect them to be lighter than the stock steel ones, even if they look bigger and bulkier. I can't tell which these are though. | ||

I didn't approach it from a weight savings intent, I wanted a better base and cover that was easier to install and wouldn't leak. I used the zippers product sold through NRHS,...BUT KEPT STOCK PUSH RODS.. I've been extremely happy with it on two of my motors . Will do it to each of the remaining if/when they start to leak, or when I change out oil pump drive gears . | ||

Im with Jolly, i am keeping my stock pushrods, the factory design to me sucked. I replaced my oil pump drive gear and cut my cam cover. Didnt like how the factory was going back together so I went this route. | ||

I think Buellistic, does not mean weight saving of the bike, weight saving of valve train, when motor revving thats more weight going up and down, always better to have valve train light but strong, adjusters are a weak point. | ||

Purpony the male female rods the three or five piece crank with roller bearings is not the best design . but if you keep changing to improve the design you would not have much of the original left. i know they are not perfect & love them how they come. it would be boring with a perfect bike. | ||

What is the advantage of switching to these adjustable covers? Sorry if its obvious to everyone else. | ||

If you are running aftermarket adjustable pushrods, the one piece covers make it hard to set them right, since you have to disassemble everything to take them out. With factory pushrods - I don't know that there is a clear advantage. Maybe someone can chime in... | ||

Biggest advantage is that they seal better and are the easiest to install. The stock push rod covers tend to leak eventually, leaving you with a few options: replace stock pushrods tube seals, reuse the original covers & bases; install billet one piece base that seals better than stock and reuse original covers ; or install this set by zippers ( or other) which installs with ease and has four points to seal off leaks. There are more than likely many other options, but these are the top three that I came across in this fine forum. Also in this forum, and many others, the second option seems to be a bit of a pain to install as the seals tend to unseat as one slides the cover and base assembly in place, something I didn't want to deal with. With the telescoping tubes, you install the base first, so you can ensure a perfect fit before torquing them down, then pop in the tubes, install the retaining cover and you are good to go. Note; there is a $27 tool by motion pro that makes that last step a little easier, but a flat blade screwdriver can get the job done as well. And as others mentioned, use stock push rods for these, so just drop them in after installing the tubes. | ||

I was pretty shocked when I found out that evos have steel pushrods. My old crappy ironhead had aluminum rods so I just assumed that they would be aluminum too. I didn't bother to weigh each though. Perhaps it's not that big of a difference. | ||

The devil is in the details !!! | ||

I thought it was in my ex-wife. In fact, I am sure of it. |
