I have a magnum that's practically bone stock the clutch has been flipped and it has a 15bing with MLM intake and exhaust I have a extra 19 phbg I'm really itching to use so my question is would I see any big changes in either torque or mph from just the carb, bigger intake and a higher flo filter would it be worth the change?
Also isn't the stock intake port a circle ? (edited)
Of the bike isn't kitted I'm not sure, and without porting i don't know if the stock cyl will be able to take advantage of the bigger Venturi.... I can tell you that the setup your running now would be a ripper with a 70cc kit...
My old magnum hit 45 with a 14 bing, estoril and an airsal kit tho...and I was 250 then
Thanks and I want to kit it I'm just on the fence on the direction I wanna go I think I like the polini reed kit or the 65 Metrakit with the ESTORIL but up keep is key so I'd be learning on the fly
The 19mm will be to much for the stock Cylinder, ported it will probably work if you go big enough, for a Za50 you should probably take it apart and look out so that everything is exactly right, because if it's not you will probably blow your Transmission faster than you would think it is Possible.

Thanks for the heads up definitely dont need to do that
Bigger carb will not help a stock setup, if you're tuned and timed right on that 15 bing then you're probably getting as much as you can out of that setup. Since correct timing on 2 speeds can require notching of the the stator plate slots to achieve, I'd start there if you're looking for gains on your current setup.
You could also get a cheap used aluminum stock maxi-style 2HP cylinder and piston and open up the ports and pop that on with that same setup. There's some good info on porting stock cylinders in the Wiki. That would wake it up some and it's a fun learning experience before getting into expensive kits.

Thanks I've thought about just taking the za50 off and placing in a time capsule lol and putting a e50 on it so I can tune tune tune the engine I have on it now is sweet and is perfect and I really dont wanna ruin it
Stock ported za is a great setup for sure, I've never run a phbg 19 on one but low 40 is pretty easy with just the 15 Bing. Going to the bigger carb will take a lot more tuning.
As others said replace the shift pucks!

You may not believe it but it may already be ruined or damaged if you have the old shift dampeners/pucks in your engine,
I’ve already took it apart a low mileage engine and found first gear needle bearing installed incorrectly from the factory that was just dragging on the main 2nd gear shaft scoring it,
Without taking a za50 apart and inspecting it It’s a guess how perfect it is
Shes been gone through new pucks,gaskets,seals the bing and the mlm exhaust are new to her and new chain and tires I've GPS'd her at about 32 flat out should I be seeing more? I also mix 32:1 not sure if that makes a difference and also will the e50 jammer clutch work on the za50?
i wanna say you should be faster.....do you know which stock cyl your bike has?
also, the za is a great engine. opinions vary, but i dont see any reason to change the engine if the pucks were done....
if i were you id just get a selection of jets and an airsal...cheap, fun, and your 80% there already....but dont listen to me

Did you flip the clutch too?
> will the e50 jammer clutch work on the za50?
No, the clutches are totally different for e50 vs za50. Why do you want a new clutch? Are your clutches worn out? Kind of sounds like you're just looking for ways to throw money at the bike...
It feels like the bike could be faster but its limited some how and I'm just trying g to do process of elimination on why it could be missing a few mph
32 is real good for one of them. biggering your carb wont make it any faster, stock high torque unported is pretty much maxed out at a 14
you might need to do some more tuning wth that MLM pipe, needle position, etc.
that bike is really clean. If it were mine I would leave the bing on just for the side covers alone. Not every bike needs to rip.

I'm fine with leaving well enough alone I dont need it to RIP per se I just need it to tear a lil bit lol if I could get like 40 with out having to mess with it I'd be happy originally I only wanted 50 I'm still new to the tuning aspect so I'm learning wats actually do able and will last vs the ladder
I dont like the mlm pipe as much as thr stock magnum pipe
The next pipe will be the ESTORIL pipe or the technigas I paired with a polini 65cc Reed kit or the metrakit65 still up in the air I might just buy another magnum to experiment with or a cobra
just buy one of each
if you make the bike too fast it will look like this.
Keep the bing, keep that MLM pipe , and get a 65 polini. I basically have the same setup on my e50 and i'm getting 50mph+ with awesome snappy low end. Prob rip even better on a za. (edited)

Yesss^^^^^^
yup yup, polini bing and done.
i dunno if that ZA is the one with the lower final gearing or the taller final gearing? I stick to the 2hp maxi ZA's. If it has the low final gears you might end up needing to grind for a 20 tooth front sprocket which is a bummer.
