We offer #428 sprockets as well which is what is shown in the pictures above. We have had extensive contact with you in the past over facebook messages and direct messages on this website. We let you know that we would provide you with updates for when and if we would have 1" prototypes...

Yes, thats entirely possible, and what some customers have done. Keep in mind that you would also need to come up with a mount for the clutch cable and a mount for the anti-rotation bracket that is used to hold the actuator stationary. Normally those two items mount off the clutch guard that is...

You can put the clutch on a standard 3/4" jackshaft with a couple small modifications. A few customers have done so with good results. The 1 inch version will come, its just hard to pinpoint when at this point in time.

He built a pretty nice jackshaft set up to hold the clutch. The motor is a 2012 Yamaha Phazer 500cc. http://i.imgur.com/n2Cg3u8.jpg http://i.imgur.com/2NxMq4Z.jpg http://i.imgur.com/KQSFEuL.jpg http://i.imgur.com/KQSFEuL.jpg

Many of you know that I am the owner of 3D Motorsport- we build manual clutches for small engines. I recently worked with a customer to adapt the 3D clutch onto a 500cc yamaha sled engine advertised at 80 horsepower/11,500 RPM. Knowing that this kart is out there and winning races with a...

I would love to see this working simply because i've never seen it done before. Send us an email at sales@3dmotorsport.net and we'll send you a $50 discount coupon if you purchase 2 clutches needed to make this happen.

The original launch price was $229.99. We dropped the price to 169 in order to attract a wider market and have sold a few hundred clutches so far at that price point. We have customers using this clutch on everything from 50cc motorized bicycles to built CR 500's. One guy is even winning races...

If i were set on building a 2 speed kart, instead of using 2 manual clutches, i would use a centrifugal clutch, a one way sprocket, and one manual clutch. The centrifugal clutch would be installed on the engine shaft. It would be chained to a direct drive sprocket on the jackshaft. First gear...

Karts and mini bikes that have high top speeds all have one thing in common: they turn a lot of RPM. Those drag bikes you see doing 80+ mph on Youtube are turning 9000 rpm minimum. They dont get to those high speeds with tall ratios and governed motors. My advice to you would be to modify that...

A simplifiied version of what you are after would be a 2 speed manually shiftable jackshaft... the jackshaft would have three sprockets on it. One sprocket would be keyed to the shaft and connected to the engine's clutch via chain. The other two sprockets on the jackshaft would not be keyed...

That issue was observed in two known cases on our 12 tooth sprockets althought was not revealed during prototype and production acceptance testing unfortunately. The root cause was determined to be inadequate press fit between the sprocket bearing and the sprocket. We issued a recall on those...

As the owner of 3D Motorsport, I felt that it would be best to not post on any public forums regarding the 3D manual clutch. I find that posts by company owners hurts online forums more than it helps. I'm posting now, not to promote this clutch or my company, but rather to shed some light on a...

Hi Scout, thanks for the input. We actually ended up contacting an industrial supplier of liners and adhesives and they recommended a system that would work with our application. The resin we are using is the same high temp thermosetting resins that clutch and brake manufactures use to adhere...

:wai::wai::wai: Video for our website please!
