That looks cool........Chrome translated the page for me quite well actually!

That little plate is to hold the seal(s) from blowing out from the increase in case pressure?

Comes out to a little over $190 USD, seems like a good price to me considering the features.Edited 1 time(s). Last edit at 12/13/17 11:42AM by mopedallday.

Tempting, but too much $$$.

Re: So yeah there's this crank for Puchs you might want to check out

I never had a seal blow out problem.

Is this a big problem on E 50s ?

Re: So yeah there's this crank for Puchs you might want to check out

yeah we were talking about that yesterday. maybe they think higher primary compression of a stuffed crank + longer stroke would blow out the seal?

i always stick them in with a dab of case sealant just to be sure, but i've never heard of one puching out.

eitherway that crank is sikkk, i still want +2 mm for 45x45 and to make the split transfer AJH athena clone kit work correctly. If anyone starts making that i'll sell half my mopeds and build that setup.

Looks like a seal making machine

ask and you shall receive. Knowing who makes it, it's gonna cost you though.

How about one free year access to my members-only moped tuning blog?

I have no idea what your selling here, but I as just saying Mw tecnik isn't cheap.

Re: So yeah there's this crank for Puchs you might want to check out

Damn it should have waited.

I've looked at their web page & although it's in Swiss/german they have lot 'n' lots of Puch parts that i've not seen before they even have new gears for my Z50 !

Re: So yeah there's this crank for Puchs you might want to check out

Is this +1mm in stroke length?! Is the Con-rode lengthened or is the actual hub larger? Plz explain

Do I need to make extra room in the case for the larger hub?Edited 1 time(s). Last edit at 12/24/17 12:18AM by countryboy1.

Just bought a full 3 plate clutch from them I had a few of the parts from my other z50's, but I have a weird 22/66 internal gearing that the Euro's say is pretty hard to find from something called a 2k maxi. So I had to buy the 3 plate 22t bell and some new pads, yellow spring they make is heavier than the MK spring in my bike so I grabbed one of those and I got the new style throw out bearings they just started making too. If you haven't run a MK spring and blown up a throw out bearing then this might not seem like a worthwhile upgrade but it seems like it will be. Haven't had time to put it in yet but I'm hopeful I have less clutch slip, the bike has pretty high comp and starting it is when you really notice the clutch slipping.

It’s stroked. Longer conrods don’t make the stroke longer, just reach further. Crank lobes are the same, just the big end pin is out further 1mm adding 2mm of extra stroke. Look up stroker cranks.

I am still building my Z50 it's taken over 2yr's now. Other peoples e50's are getting in the way :( but i will be getting there clutch kit soon as i am aiming at 50-60mph, so the engine is a bit tuned high comp head , 50cc 6port full crank, 19mm phgb carb, H4pipe & Hpi :)

Re: So yeah there's this crank for Puchs you might want to check out

Any one got this yet? I was looking and it mentioned a 16mm conrod bearing, and it wasn't clear if that was a bigger pin on the big end of the conrod or a larger outer diameter for the small end needle bearing...bigger outer diameter of small end would open it up to running piston with a 13mm wrist pin

Re: So yeah there's this crank for Puchs you might want to check out

Weiseco makes a really nice 16 o.d. x 12 I.d. wrist pin bearing. I think treats has something as well.

Run a reed induction kit , Athena makes a 50cc one if you need 50 cc

Yea I saw the one on treats! I do like the idea of a thicker more robust needle bearing, but I've also found a few 16od 13id bearings that means I could use a piston from a scooter kit with a 13mm pin without getting a new rod pressed into the crank... planning out my first case induction :P

Re: So yeah there's this crank for Puchs you might want to check out

Don't go for a scooter kit, the am6 stuff is a million times better. There's the Airsal extreme kit for sale on treats right now for like 170 bucks.

Re: So yeah there's this crank for Puchs you might want to check out

Ok rad, is the timing generally more conservative with the shifty cylinders? I've been looking on some of the euro suppliers sites and it looks like a lot of the more prevalent cylinders have versions for different motors, like I've seen those airsal Xtreme cylinders for am6, derbi euro3, minarelli horizontal. I figure I'm probably getting the cases cut down and a block welded on with new stud holes to match whatever, and probably moving over that case bolt that's real close to the transfers.

I am strongly considering that airsal xtreme kit, that looks super rad for as cheap as it is. The whole 13mm pin idea was from looking at the bidalot rf-wr cylinders, the ports on those look super sickkk but that's $$$.

I still needa crunch the numbers on spacer block thickness vs conrod length and stroke and cylinder height yada yada for getting the port timing right. I mean yea ideally the same stroke as the crankshaft but spacing up a 40mm stroke cylinder or milling down a 45mm stroker isn't unreasonable and could probably still get some usable power enough to make it worth it... probably just pick something as close to what I end up with and making it work

The Rod is the same, the Stroke ist 44mm instead of 43mm.

Thank for that ken. i've already got one and all the other parts to go with it, i'm just too slow in getting it on the road. if it was my only bike then i'd pull my finger out and get it done but it's a long term thing, When i do get it going i'll post a right up on it, this is the bike as it is at the present
