My 2013 skyteam flashback z50 clone

[BLACK DEATH]

My 2nd post here, I have a 2013 skyteam flashback 125 4 spd clutch.
When it was all stock, around 45 mph was top speed.
What I found the issues were...
Stock exhaust has a catalytic converter which chokes it.
Stock carb is junk or was with mine as it isn't adjustable.
I added a free flowing exhaust & a 22/24mm mikuni clone carb.
It rips now and the speedometer says 65mph on flat ground.
This is with stock 15/29 gearing & 3.50-8" tires.
I put a 17 tooth front sprocket and still go 65mph with lower rpms on flat ground. I run out of room to see if it will go faster as the engine may not have enough power.

I just bought the piranha 150 e start for it.
Why I don't know as its good with the 125 but we all love more power & torque.

Wow! Plan on adding an oil cooler, as conventional wisdom indicates an oil cooler is wise above 140cc.

We're gonna need pics of the process!

[BLACK DEATH]

Yeah ill probably add one soon after I get it running good and then make sure the lighting output is working correctly. It can run without an oil cooler but for longevity an oil cooler is a must.

These guys have been getting some good power out of their bikes

Curious to hear what the 150 does.

[BLACK DEATH]

Engine arrived I just don't know when I'll start working on it.
I also need to decide if I want to run a true mikuni vm 24 or 26 carb with it.
26 for more top end for sure
Also change out the exhaust with a larger diameter one.

Plug and play? Please document the swap out.
Mind posting the site where you bought the 150?
What size/make carb is on the 125?

[BLACK DEATH]

plug and play it should be other than the wiring. i just got to make sure which wire goes from engine harnes to body harness so it runs & charges the battery properly.
The engine will drop right into the bike and bolt up.
I bought it from wholesale cycle but tbolt sells it also.
It was on sale at $100 off so I bought it.
The two websites below have all kinds of go fast parts for our bikes.

The stock locin engine has that pos one that doesnt adjust much so i put a mikuni 22mm carb like this one. You can find it cheaper on eBay or other sites for around $35. They should all be the same

BD,
Thanks for the info.Awaiting your install and results.

X2! Please take pics of the process.

[BLACK DEATH]

I will do that.
I just need to decide if I want to put it in this one or my other 2013 skyteam that's in black.
I mean I love my maroon one and it runs perfect, so why mess up a good running bike.
The black one is brand new and hasn't been started up yet. Just put together.
I also have a few other 50s, two Jincheng panda fun riders 50cc 3 spds. Years 99 & 00 6volts.
All titled in my name... I need to liquidate as I have too many mini bikes...
I also have a few honda z50r bikes

The black one is the dummy pic as I haven't taken any pics of it yet.
Since its black & chrome I'm either going to black it out or leave it chrome with more chrome or aluminum

[culcune]

Why not throw the engine in one of the Jinchengs? I don't think they are worth anything as a collector's item, and like you said, both your Skyteams run fine in 125 form, so why not hotrod one of the weak links to your collection--one of the Jinchengs?

[BLACK DEATH]

I have thought about that but a few things conflict.
The frame length is shorter so the head may hit the tire when the forks compress.
It's better to use a smaller engine for length purposes as I don't want to upgrade the pandas suspension at this time or even ever since I have the others.

I do have a semi auto lifan 125cc engine to swap into one of the pandas. i also have a semi auto 4spd 50cc with an e22 head that rips for a 50cc & a manual 4 spd 110cc.

Did a mph GPS test with my phone.
Darn site won't let me upload from my phone a screen shot.
Against the light wind we had it was 58mph.
With the wind it was 60mph.
I need to put my rpm gauge on the engine also to see what rpms I am turning the 125
The 17/29 might be too much gear for top speed as the 125 might not have enough in it.
The 15/29 gearing got me the same or close to same mph per the gauge.
I should try a 16/29 but I don't do a lot of top speed runs all the time.
17/29 does keep,the rpms low through out the entire rpm range.
Also the speedometer gauge said about 65mph on it, but at the angle we ride it may be higher and I'd rather look forward than down most of the time.
Either way I'm happy with 60mph.... For now... Haha

Now I need to swap in the 150 engine and add/buy a bigger carb.
May also upgrade the exhaust to the side like a big bike.

Photos of the swap.
Thanks

[BLACK DEATH]

I will post up when I start the swap.
I honestly do not know when I'll start it but maybe soon... I hope.

[BLACK DEATH]

I also GPS the red panda with everything stock except the exhaust it did 34mph.
It may go 35 mph or maybe a little more but I ran out of room on the residential streets.
The big gun exhaust sounds deep and throaty.

I'll be watching for that!
