I am the proud owner of a 1999 m2. I have recently purchased a set of zippers billet push rod bases and adjustable tubes. Can I use these bases with stock push rod tubes? It seems the kit i purchased didn't come with all the o'rings I required. thanks for all your help in the past. sportycraig | ||

"YES", but the only way to reuse the OEM stock push rod covers is to remove the heads ... This is where the adjustable tubes save you take apart time ... You still are going to have to take off the rocker arms, then cut the OEM push rod covers to get them out ... Before adjustable push rods come up, "WELL" IMHO the valve train is heavy enough already and "i" would never put them in my engine !!! | ||

thanks Buellistic. I have the heads and barrels off, but the bottom of the tube seems to sit about 1/2 an inch higher up due to the thickness of the billet bases compared to where to tubes sit on the stock parts. will I have to cut the original tubes to fit? | ||

You still are going to have to take off the rocker arms, then cut the OEM push rod covers to get them out ... WHAT!?!?!?! The tubes are the cylindrical covers You do not need to remove the heads to remove the push rod tubes! You only need to remove the rocker boxes to remove the push rods to remove the tubes. I am not sure if you can use the stock tubes with Zippers bases, call up zippers I am sure some one there will be glad to answer that for you. | ||

I've never dealt with the Zipper's bases but if they're anything like the NRHS bases you'll need plenty of lube and patience. At first you'll swear they'll NEVER fit especially with the gaskets installed much less with the gaskets installed flush in the base but alas they will. And if it's a one piece base you'll get one in (finally) and knock it off wrestling with the other, this is where the patience comes in. Good luck. | ||

What Spidey said, no need to cut the tubes. | ||

I think what NRHS sells is the Zippers stuff. I'm pretty sure they say that on their site. | ||

The DIFFERENCE between NRHS and ZIPPERS is the ZIPPERS push rod bases have a "O" ring for better sealing on the bottom of the push rod bases where the HRHS bases does not ... The collapsible push rod covers will take care of added clearance in thickness of push rod bases ... Nice to know you have the heads off ... (Message edited by buellistic on July 16, 2010) | ||

Then which do I have? It has NRHS engraved into the top but also has, not an o-ring, but a tapered round rubber gasket that goes in the bottom of the base.  | ||

Those are the NRHS/American Sport Bike hold downs. They use stock or after market gaskets. Make sure the hold downs and gaskets are squeaky clean then use 4 SMALL drops (use a toothpick) of super glue spaced equally around the gasket. Press them into the holders and let set. Then use a THIN film of oil on the tubes and press the holder down onto the tubes. This has been gone over a bunch of times in the KV and Old School threads. Search it out and check it out. Brad | ||

Let me say I took that picture from NHRS's website before something gets started. I used their pic because that is where I purchased mine from. I may have had more problems because I used the black pushrod covers from a 2002 and others have said they are a tad thicker, my measurements didn't say so but oh well. So just to be clear that isn't my pic. I do have a pretty pic of a blacked out motor if anyone wants it. I'm sure it's on here somewhere. | ||

Those can be a little frustrating. One piece of advice: Throwing things doesn't help, you still will have to take it all apart again. | ||

My advice is to grab a beer and let someone else put them on while you watch WSB  . | ||

This is what worked for me when I installed new push-rod base seals into my NRHS billet base-plates. While looking at a side view of the baseplate with the cone shaped push-rod seal seated in the baseplate cutout. Correct method: The cone shaped seal sticks out of the bottom of the base about 1/16" Incorrect : The cone shaped seal is shoved up into the base and the bottom of the seal is glued flush with the bottom of the base If the incorrect method is chosen the top of the seal will be too tight to accept the push-rod tube. I found the four small drops of super-glue worked great along with some syl-glide or oil to lube the pushrod tube/base seal. | ||

+1 to that great info jim2 Those one piece seals can be a bastard to get on.....But once you do it should not leak for a long time. When i first got my bike and it dropped an exhaust valve and i repaired and reassembled the top end. I had pulled the tubes out and i didn't know any better and i had no manual (yet). I didn't change the seals. When they popped and oil went everywhere (1000 miles) I looked at them and i was amazed that they even held up the way i just shoved the tubes down with the head. | ||

Jim2, That's the way I've done it for years. Took a few tires to figure it out but now it's a snap. I keep a package of cheap super glue in the tool chest. You know, the kind you buy at the dollar store for 4 tubes for a buck. Use a tube, and chuck it.. The trick is to use a SMALL amount. To much or in the wrong spot and like you said, you can't get the tube inserted. Don't ask how I know... Brad | ||

Ok... so does anybody know how to get the Zippers Adjustable covers off? Their Website doesn't seem to have installation instruction. These are on my '98 S3T. One of the pushrods sounds like it came loose so need to pull the covers and before I start reefing around on them I figured I'd ask |
