I hear the non-variated class needs some more competition 😉

But I'll have 2 engines at the end of the day, same A55 setup and this.

Re: Ye old 50/50 build

Thirty five years ago I switched the rear sprocket on my stock V1 Motron from a 44 to a 36 and could do 40 mph. I learned graphing on Microsoft Excel today and entered speeds vs gear ratio for 9, 10, and 11 with a 44 assuming 20, 25, and 30 mph along with my 11 & 36 going 40.

I have a 17 inch rear wheel from a Franco-Morini bike with a 26 sprocket and the trend line function predicts that the sprocket change alone ought to get me 50.9 mph. Since the 17 inch tire is 6.025 percent larger than a 16, I'm thinking I ought to make 54 mph.

Yeah, it will take a while to get there and it won't climb hills. And of course it's all B.S. until I actually try it.

So would I still make the 50/50 club if it's not the original/correct rear wheel for the bike?

Sure why not?

I figured I wanted to build something that could rip off the line til 50 so it's more practical for city riding, so rather than gear it out I just tried to produce more rpm.

I guess also the bike has to produce enough power to get you to that rpm too, you could theoretically gear to hit 100mph but the engine won't be able to get there. So in theory any speed is possible. (edited)

Re: Ye old 50/50 build

So I slapped the A55/E50 on the bike and have been messing with this Peugeot Artek ignition.

My timing light cuts out so I don't know what kind of curve is in the box/coil. I'd imagine it's somewhat aggressive if it's for a Pug tho.

60W of power too!!

Still playing with the tune, but it certainly has higher compression with the lathed head.

Re: Ye old 50/50 build

Got 48mph with the 15mm polini and stock bell and starter plate. 16x45 gearing. Gonna throw a 40 on the rear and see what I can hit.

Tuning the low end so I can pull start and Mr. Cool ice with confidence. Ditch starter plate and put in a lightened clutch bell. I tried to tune it with a pull start (string on the ninja start thing) but with high comp and new rings it was a pain in the ass to get going.

BTW, I set the Artek ignition to about 2mm btdc firing with a timing light and it works well. At first I just set it up how I would an MVT but it was firing near 4mm btdc 😬 hot hot hot..

Trick tip if ya don't know, small pug taper is same as E50. Which is why I'm running this ignition (cheaper than an hpi).

Pro tip 💕. Going down in the rear you will hit 50 easy.

Easy peasy! A55 to 55mph???

I think it will be close for sure!

Re: Ye old 50/50 build

Same taper but the stator bolts line up too? Or did you get creative with that as well? Does it have a lighting coil?

Bolts will line up. Peugeot bolts are M5 vs puch M4 tho. Pic shows how they line up.

So you can run long M4 bolts and center it.

I ended up tapping mine out for M5. Lined up close but ended up taking a smol amount of material off to get the whole thing centered.

Has lighting coil. 2 wires for power actually.

Re: Ye old 50/50 build

Welp. You let the cat out the bag. New fad.

I’ve actually been wanting a better cdi but refuse to get a shitty hpi. They always break. Where did you find it? Treats is out of stock on most pug cdis

Re: Ye old 50/50 build

Meow!

There are only 2 left but this is what I am using. Only have 50 miles on it so far, but seems decent. So I didn't use the base plate, I literally just took the outer ring thing and bolted it on, just gotta mess around to get it concentric cause there is no centering ridge for it to slip into.

Re: Ye old 50/50 build

do you know what the tuned length of that pipe is?

You could calculate the length using Graham Bells book. But I feel like there was a general table with lengths and rpms just to compare.

I had a pipe that was similar in length and I was hitting a wall at 10k. I cut out an inch of the header and then could get to 11k

I prefer Art Bell's book

Shortening your hog is definitely the secret to untapped top speed

Re: Ye old 50/50 build

I am curious. I have a 3 shoe clutch (bought it from treats like 10 years ago) 18/40 (I think 40) gearing, Dellorto sha, and a tecno bullet. I previously had a 12 tooth front sprocket. It ripped off the line to about 28. Changed the front gear over to the 18 and it’s a dog off the line. (I think I need to turn the screws in on the clutch shoes, I think it was the “break in” period) it was getting later to where the clutch grabbed. Now I have to hold the starter lever after I take off. But I hit 32 mph. I can let off the lever around 18 mph (roughly) I do want to open up the intake and exhaust ports, probably after I tighten the clutch up a bit.

I’m not trying to hijack your thread. I am just looking for some input.

Yo, yea so yer gearing went from a 12 front to an 18 front yer low end is gonna change. You shouldnt have to hold the starter clutch in to get to 18mph tho??

Turning in the clutch screws with increase the rpm at which the clutch engages, so that will help with take off. Shoot me a PM if ya want!

Dude you have some major issues, never should be using the starter clutch for driving!

Start a new thread in repair or performance and we'll figure it out.
