Clutching on the cheap

[yamamarc]

You cannot run washers under helix. The 3 sliders will quickly be ruined.

I have washers under my helix and my slide are still okay so far 800kms

Is that not what they mean by "shimming the helix?" To prevent coil bind? I have three .060" washer s under the posts and seems to be fine after 2200 miles.

Get them out. They are just for testing.

How's this hurting anything? I've done this for years. Stock Yamaha springs will bind otherwise.

not sure Cannondale please explain

Some aftermarket helix's are short on tower height, that would be the only way it would hurt anything. The shorter tower top could clip the button....but the one in the above pic has long enough towers...

 

[sparky72]

Yep, that's how mine look.

 

[cannondale27]

I have the same one as in pic. It is not long enough

this is after 800km of hard riding pics taken today!

I don't see any issue unless I'm missing something

thanks Cannondale is making me paranoid!!lol These are slides he is taking about right? They haven't changed in shape what so ever since adding shims!
Cannondale are you sure you have the same helix I do? 45/39

Lightweight primary spring (stock) or heavy secondary spring are much more apt to slip the belt.

Think ya got that backwards. Just sayin

You see how the corner of the helix is on the pad. Thats the problem. Maybe its just how I ride or maybe my setup but that corner dug into the pads and cracked them. Guess once again I am just "special" but really just something to watch for. Mine lasted probably 3000mi with washers. Dont shoot the messenger please
