Topic: CycleX Primary Tensioners vs Stock

[Greggo]

Primary chain tensioners: Go with stock NOS (can be found), or get the new Cyclex piece with its heat resistant material?  They're both the same price, and the Honda parts have been proven to deteriorate over time.  What do you guys think?  I'm rebuilding a sandcast motor.



"Introducing remanufactured OEM tensioners with our special material for the wheels unaffected by heat and will never wear. This is the same material used on our cam chain tensioners and manual primary chain tensioners. Guaranteed for life."

Just noticed the notches. No rotation?!

Correct.  So, all the wear would be on one spot, versus being distributed on the entire roller of the honda part.  Would the harder slider surface wear out stock primary chains faster than a softer rubber roller?  I'm thinking I should find a NOS piece for a sandcast motor, and maybe try this one for a higher HP build (next bike).

So the rollers on the chain do the rolling not the end piece? Hmm.

I eventually used a piece of Delrin for a drive chain guide and on it the side links wore into the material until the rollers made contact, then the wear was very minimal. I imagine the same would happen on this piece.

I don't mean to be a doubting Thomas and am not saying this wouldn't work, but I'd like to see one inspected after 10,000 miles.

+1 I'd like to see one after actual use.

Prototype. The production pieces are rollers. Kenny needs to update his pictures.

That would be good.  This info is why I pose this type of question here, thank you kmb!  I think my mind is made up now
