Insane ZA50 gearing

Wesley Ambrosini /

TCCD 50cc no transfer porting

Hi comp head

Techno circuit pipe

15 Bing

Had 18x37 on it and it had insane low end (for a moped)

Grinded and slapped a 20 up front, still has great bottom end and actually pulls it.

Is there an end to this madness?

Will it shorten clutch life to have this tall of gearing?

If it takes off it's good right?

I run 20 x36 on mild kitted bikes and 21-22x35 on hi powered kitted bikes like Gila Athena and polini reed kits, stock clutches are asbestos lined and last forever/very long if they don’t become delaminated, (aftermarket clutches do not last like stock)

So run synthetic motor oil 5w20-30 not type F oil fluid, make sure you have brand new pucks/shift dampeners and flip second gear clutch, if stock crank run good synthetic 2t oil and don’t go more than 50 to 1

Thanks boss

I'm gonna throw some 5w30 in it tomorrow and check it out

Re: Insane ZA50 gearing

Yup, trust the roffman, 5w-20 is the way to go on puchs.

Started running Mobil 1 synthetic 5w-20

Honestly the shift RPM was very similar maybe 200 rpm higher, but the shift is much more controllable. Also it the shifts stay consistent as the motor warms up

Honestly the powerband is so shit after the shift that I went back to a 18 in the front, ordered a 19

Did you go any faster?

Re: Insane ZA50 gearing

I'm running 21/37 in my Polini za50, no issues so far and I'm running a stock crank.

Re: Insane ZA50 gearing

20x40 on my Magnum MK....it eats hills for breakfast and is hella fast at that. I did notice a difference when I switched from an 18t to 20t. Stock crank...running type f still :)

Top speed was faster, just took all day to get there

Re: Insane ZA50 gearing

I am rebuilding a MAGNUM II and have been reading your write up on using synthetic motor oil in yours. Did you use regular Mobil 1 or the Motorcycle Mobil 1 that is made for wet clutches? Thanks for your time.

regular ass car oil 5w-30 synthetic

10w-30 seemed to put the shift point too high, but it my be on my head

Re: Insane ZA50 gearing

I think Rodney ran 22x24 gearing on his 74 mph speed run

The hard part is finding a snowflake sprocket

It was something close to that so I thought my ZA could pull 22x36.......it could not

Re: Insane ZA50 gearing

Wesley Ambrosini /

Just kitted up to 70cc, my za now easily pulls a 21x37

No replacement for displacement

Re: Insane ZA50 gearing

It all depends what you consider pulling....

My ZA50 was just a simple ported kstar/vm20/gigantour chamber, and it pulled very well with 22/36, rocked dubs uphill steadily and would cruise around 50 with 300+ pounds of combined human meat on top.

Man I I’d not get that. I have basically the same setup but a 21phbg and mini rotor with a 70cc Athena PP kit and it crushes 18x36 but I go bigger and fucking Tomos beat me off the line......I can’t live like that.

Re: Insane ZA50 gearing

I don’t know how you can get a 22 on a Za I barely got a 21 on mine. Grinding the case and there is barely an 1/8” space left.

Re: Insane ZA50 gearing

Za clutches are weird man, They’re all so different feeling! Year to year, model to model it doesn’t seem to matter, no two are alike. You can blow through the case it’s no big deal, just gotta keep that chain clean. I’ve seen tomos sprockets on za before, Idk how it performed though.

This is the biggest thing. ZA's seem to have so many minute manufacturing variations that account for every one being different depending on the model and year bike it came on.
