What kind of epoxy did you use?

The stock one are just as hard as the epoxy ones I made.

Motion Left Mopeds will be selling OEM pucks for the two speed by the end of March.

do you guys mean urethane resin? seems like that would be much closer to the stock.

this business of tuning how the bike shifts.. that has me intrigued. does it really make a difference? what changes? i dont see how it could affect the shift point, but it could definitely keep you from shredding clutches/cranks/etc.

I agree that epoxy seems too stiff for this application. That's why I asked what kind you were using. I thought you had discovered some new epoxy that isn't as hard as a a rock. Urethane resin, though, hmmm.......

hmm interesting. i like the hose idea, i was thinking of doing something like that with hard machined aluminum centers, seeing as i have a huge selection of various hoses at work.

stickin' to my E-50's for now though.

Rigid's

In fact the black set pictured in the image is of rubber matting. The set I’m currently using in my 76 is made of commercial spray-on truck bed lining (Rhino lining / Lava lining etc…..). My friend worked @ one of those shops and squirted some of that bad boy into a pie-pan to the needed thickness & cut it out later. It’s impervious to chemicals….. other than that it’s stiff and has held up to my kit.

I use other methods though- never ever weld the shaft & gear together in hopes of solidifying the shift.

I've been sucking all the Za info. lately

devin that's cool...you folks are manufacturing some. hopefully it holds up better than the OEM. normally the OEM dampers doesn't hold on kitted bikes and peeps who has clutch work done on their ZA's...OEM will hold for a little bit, but eventually the dampers would just get shredded. when the bike shifts, with higher stalled clutches + kitted, will produce some great amount of torque and the dampers absorbs that torque while it shifts to second...and without good solid stiffer dampers kitted bikes would shred those dampers. for over 15 years we've been making it out of different material that'll hold up, against faster bikes, and absorb the torque. hope others have other ideas on making stiffer dampers....i use hard rubber matting in my za's and those have lasted me quite some time now. IMO polyurethane material is best. www.urethane.net could probably make some not sure of their prices. i'm sure there are others than can manufacture these. or if anyone in MA can make these out of polyurethane, let us know.

the nickels are way too stiff, need something a little more flexible....something that'll absorb the impact of the torque and hold without falling apart...the nickels probably doesn't absorb that good at all...hence the shredding of the gear...

The new ZA50 pucks from Motion Left Mopeds will be available soon, please respond with your interest and how many sets(3 pucks) you will need so we can have enough for everybody.

anybody ever look in to lexan/polycarbonate. that stuff has a surprising amount of flex, yet is super stiff. you can buy rod, tube and sheet in all sizes pretty easy. maybe slices of tube, and you could dial it in using different tube i.d.'s (different wall thicknesses)

just throwing crazy ideas out there

Driving down the freeway, saw a recap by the side of the road and wondered: Would recap material (especially those large squarer areas on the edges of big truck tires, don't know the technical name) work for carving dampers? Hard rubber, but not too rigid, durable. Just wondering...

I'd be down for a set.
