45 Tooth is standard equipment on stock 2hp Puch E50's.

Re: Rear sprocket

Not that you are asking about ratios , but , in the big bike world , we usually figure dropping one tooth in the front is very close to adding 4 teeth in the rear .

Maybe you're asking if there would be any chain clearance issues ?

Re: Rear sprocket

I have 2 speed puchs with 5 stars and they are 40

Yep, Stock gearing fo ZA50 1.5/2HP is 40 rear.

Re: Rear sprocket

If I put the 45 and change the chain would it make that much of a difference

Never seen a Puch with anything different than 45 in the Rear.

Better take off and slower top end most of the time

Acceleration would increase quite a bit, but your top speed would decrease. Typically, I go the other way with ZA's, especially with flipped second speed clutches

Re: Rear sprocket

Yea, your za50/polini should be running 20x35 gears or so.

I run 21x35 on polini kit 4 pedal reed cage and derestricted estroil pipe flipped second gear clutch on za50 and go 55-60 mph all day long and that’s with static points ignition and around 14° BTDC timing!

Ken you don't quote someone then add words to their statement. It makes it not a quote anymore when you do that.

Maybe you should read his post again .

Seems to me he's stating what he runs as a comparison .

Re: Rear sprocket

Its not that big of a deal, but he did add a words to my statement in the quotations from my original post.

Dude the chain is going to count the teeth. 16x45 & 11x40 are the same.

Actually, the 16/45 is closer to a 14/40 or so.

Yea I know if you look at the spreed sheet rpms I posted it says that.

Math

45/5=9

40/5=8

16/5=3.2

11/5=2.2

Does anyone know why this happens?

It's simple math : Division .

And , the chain doesn't matter . It gets adjusted to the sprockets that are chosen .

I wasn't sure exactly what the OP was asking , so I offered ...
