Does anyone have experience with using the Sumax pushrod tubes? Will they work with adjustable pushrods and any leaking concerns? Looking at trying a set on a Twin Cam.

Thanks,

They are very nice looking but in the past I have had issue with the threads galling. After speaking with them about it I can away with idea that they really where more for looks than use.

You're probably right. Somehow I just can't figure how people can make stuff like this when proper functioning is usually not many steps further.

I have used Sumax pushrod tubes on my bike for over 10 years and have never had a problem with them.

Of course that doesn't mean none of them don't have problems.

I had heard good things about them but after having issue with several sets we did I stopped using them. One thing is the theards are very fine and I did use anti- seize as they suggested but when I went back into the engine 6-7 months later to do a cam swap I could not get them apart, and when I did they stripped out. We did several custom TP engines for a shop and used them on all and all had issue's. But hey maybe just me and too much lizard juice and CRANKED them down to hard LOL

I agree, if all the products that didn't function properly were eliminated, the aftermarket would thin out considerably.

Listen... to each their own, but it is my belief that the lizard juice factor should figure into damn near anything designed for use on a HD. As a matter of fact, the ISO should include a manufacturing standard which compensates for the lizard effect.

Thanks for the comments - decided to spend the money on forged rocker arm supports.
