Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Changing the vari belt to the inside and rear pulley to the outside of the double sheave pulley

Have to make a thinner inner pulley swinging arm to be able to space the whole assembly inward towards the swingarm more, or to have to the option to if testing shows I need it

Think I came up with the final mockup late today. Hopefully tomorrow I can test.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Boom.

Works great so far.

Rode it around and it works as planned

Only prob is that I need a diff length belt, rear belt hits the pedal shaft housing at full variation.

Using 2x 4L280 now (30in outside)

Will probably do a 31 inch front and a 29 rear. That should do it.

I have video If someone wants to post it somewhere, it's on my FB

Want to see the video now!

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

New belts, no rubbing now.

Now I gotta refine it.

Outer top support to allow it to run looser and swing easier,

Probably will look for the dayco top cog in these sizes, they're a lil over 1/2 in, or maybe try a wider rear belt if I can find one.

But fuck it, it works.

You should try to make one, but you won't...

Maybe make one then?

Took me about $20 and some scrap steel.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

2 different sizes pulleys could change your gearing as well?

Exactly. How cool is that????

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

f you wanna try this on a hobbit, I already did the hard work for ya., Front belt is a 4L290 (31in outside circumference) and rear is a 4L270 (29in outside circumference)

Pulley is a gates 36103 3inch double sheave tensioner pulley

God luck and good speed!

That is inexpensive.

Cant wait to see the video jbot is gonna post today, standing by ready to view.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

So inexpensive.

Any poor dummy should be able to do this.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

The only drag about this is the variation with a half inch belt.

Just don't get enough.

But!

I've got some ideas.

1. Machine the hobbit pulleys to be more steep, so a 1/2in belt can ride all the way up.

2. Change the rear side of the tensioner pulley to be smaller as to raise the ratio. In theory you could increase gearing to extremes never before dreamed of on hobbits.

I'm so surprised that I've never seen this built before. it's so dumb and amazing.

Now for tuning.

I'm going to first lighten the weights and spring as much as possible.

I gotta add that Variator brake but that's going to require some weed and some pondering and Cy Thoth in the garage. Maybe today.

Do I have any more brake calipers tho? Idk.

And my motomatic pulley is fucked, all bent up. Those gy6 pulleys are such fucking garbage. I gotta either bend it true or pop out the center taper plug and press it into a jog or Zuma rear pulley.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Last day to work on it for a bit.

I boxed in the pulley, and moved the lever arm to the center bottom of the assembly because I was flexing the assembly when the mount was on the side.

I learned something funny.

Can't press the lever upon takeoff because the rear belt and pulley will slack, creating a crazy belt slip.

But otherwise it's all pretty great.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Would a driven pulley with different shaped guide slots fix that? Have never looked at a Hobbit but the ones I've handled are designed so the pull of the belt makes it want to open. Or maybe just a really heavy contra spring?

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

It's not a big deal.

Hobbit don't need a launch lever at takeoff anyways.

It was just funny about the slip due to the front belt stretching when pulled.

And if I wanted to Fix this the answer is to do a roller tensioner pulley on the back belt somewhere.

That would keep tension on it all the time, even if slacked a bit

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Ok, today was the last day.

Yesterday was so hectic, just needed another day to refine this enough to be able to ride a lot.

I changed the lever to arm positions to allow less travel on the footy guyee during variation.

Sticks out a touch, but it'll do til I get more time to fancy it up.

I'm very impressed how much this really kicks ass. Almost no belt wear so far, much better than the PATbutter.

Dying to do the variation lock, but that's for another day. Maybe after I get some fucking work done, stupid ass mopeds make me not wanna do my job.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

And just to shit on everything above...

The Hobbit driven pulley is exposed, not hidden behind a clutch like on scooter stuff. Would you have been able to achieve the same ends using an arrangement like the throw out bearing on a car's clutch to press the sheaves together when desired?

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Maybe, but it's apples and oranges.

Rodney's derbi has something like that, but this is so easy, so cheap.

Works so well.

Lots of ideas have been thrown out there, this is what I chose to build.

Not a huge fan of pushing on spinning weak ass thin stamped steel. So yeah, maybe it would work but that's for someone else to try.

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Your ass is DUSTED BROOOO

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

Vid is choice homz!

Re: New dual variated launch lever, brought to you by Crazy Wayne and Jbot

That is impressive! Not familiar with hobbits, where's the centrifugal clutch?
