Re: purple pain, full rigid maxi build

winning awards already! thanks mike! <3

btw, I never got out of mopeds, just slept a sec while in a shitty anti-moped town. :P

mike sent me the pedal chain tensioner, so hopefully i'll have some skid videos tomorrow! also got my gila to fit the cases, so maybe it'll be running soon?

Re: purple pain, full rigid maxi build

Pic of the tall bike?

Re: purple pain, full rigid maxi build

i can probably get tall bike pictures later if i remember

Re: purple pain, full rigid maxi build

keeping this one pretty mild since the kit's already had a hard life. my hope is to one day put a za50 on this thing, so I don't want to go too crazy with the e50.

port match roughed out, I may build the bottom end later today.

brandon called it! I did some up and down the street push bike style brake tests and under hard braking, it'll skip a tooth once in a while. if I slam the brake super hard, it'll do it almost every time.

I knew it was a possibility, I was just being super hopeful that it wouldn't. I used a pre-existing hole in the frame for the spring mount and was just hoping it would conveniently work out.

not a big deal, I can make a bracket and get better chain wrap and/or spring tension.

otherwise tho IT WORKS REALLY WELL!

Re: purple pain, full rigid maxi build

Maybe spring the chain end to the chain coming from the brake arm , with a bit of tension ?

That would provide as much a wrap as possible .

this was my original idea, but i didn't like the idea of constant pull on the brake arm that the end of the chain being sprung to it would cause, if that makes any sense.

current plan is to just build a little bracket that puts the spring lower and further back some, and possibly a bit stiffer spring, or some more tension on this spring.

i'm back in oregon for a week or so to gather some of my stuff/see family, but i'll get back on this once i'm back in fe

Maybe a bit more clear :

"spring the chain end all the way around the sprocket to the chain coming from the brake arm , with a bit of tension"

Maybe not .

Re: purple pain, full rigid maxi build

nah, i gotcha. kinda like this -

shit.png

at least i think i gotcha. the spring pulling on the chain going back to the arm is gonna be pulling a bit on the arm and i don't wanna deal with all that, moving the spring anchor spot lower should do it.

it's all experiments and trying things out, but i feel like a bracket either bolted or welded to the frame will geter done.

Yup . You illustrated what I meant .

I don't think there would be enough tension to effect the brake arm adversely .

Sure , there'll be some , but , probably not enough to make the brakes drag .

Agreed ... experiment . ;)

Y not a pushrod?

Re: purple pain, full rigid maxi build

I wonder if you used a hose clamp around the sprocket and chain, or drill a hole in the sprocket and push the last link of the chain pin through the sprocket.

Re: purple pain, full rigid maxi build

nah, the end of the chain needs to be secured to something via a spring to keep the end from going too slack when the brake is in use.

a bracket lowering the end of the chain should do nicely.

Re: purple pain, full rigid maxi build

so I'm back in oregon for thanksgiving and to collect some of my stuff (tools, moped shit, my jeep, my cat) before heading back to santa fe. digging through my moped shit I found a solid, stock za50 bottom end.

I'm gonna move forward with the e50 build for this bike for now, but I'mma rebuild this za and it's probably gonna end up on this bike eventually!
