ZS190 Swappers!

[PhildoScaggins]

Anybody want to sell me their old motor? I've tried replacing the jug on mine, but after having problems with things fitting, I just want a new motor. I live in Maine, would be willing to pay plus packing and shipping fees.

[Whisky]

I will be doing the swap but won't happen for several months. U can get new engines for a little over 200.

Really? I've only seen them priced around $350 not including shipping. I've considered doing the zs190 swap myself, but I'm about to take on a mortgage :yay: I'll keep you in the back of my mind come springtime when I pull all of my broken bikes out!

I have a 125cc motor off my 2017 SSR Razkull I'm looking to part ways with now... has about 2,000 miles on it. Broken in properly, oil changed every 300-400 miles with Mobil 1 Racing 4T 10W-40 motorcycle oil. Oil filter screen pulled and cleaned every other oil change. Will throw in an extra brand new clutch cover gasket from tbolt usa.

It's a three bolt pattern design just as a Honda grom has, may want to double check but you will probably need engine brackets to use this in a clone (Boom, Venom, Vader, etc.) Shift pattern is 1 down, 3 up. 16T sprocket on it. PM me if you're interested!

Thanks! about two weeks too late though. I bought the zs190!! When I saw I could get it for $640 I just had to make the purchase. hopefully I will have it in by may.

Nice.

@loganlex - I told ya about pulling trigger on that coupon on your "Looking for thoughts and ideas" post yesterday haha. Not sure how much longer Gary at Pitsterpro is going to be running that dirtcheap bargain...
if that coupon code stops working you can always use "miked" at check out...comes out to $743 w/ shipping

[Whisky]

Would highly suggest changing the swingarm with something stronger if swapping to the 190. I put a Grom swingarm on mine and replaced the rubber bushings with the brass ones from mnnthbx.com

I know you've kinda just gotten started on your swap, but have you had to tune the carb that came with it at all, or just running it stock?

[scoot newb]

I opened up the Tao Tao motor and found this inside.

You should upgrade to the 32 oz. Bud Light big bore kit. :lmao:

[scoot newb]

For real! Tallboy stroker kit.

[RKG83]

Man I’m tempted to go with the 190, 125 isn’t really cutting it and I don’t wanna buy a new bike cause I’m pretty happy with it. Just want some more power.

I ordered one yesterday. I'm looking forward to having real chain adjusters lol. Any real need to change the bushings if they are in decent shape? Mine is coming with bushings, chain adjusters, and chain guard for $119.

[loganlexow]

What's it take to do a swingarm swap? Does the grom arm bolt right on??

[PhildoScaggins]

So I'm told. Pretty much all the grom parts bolt right on with a few exceptions. I don't know if the grom swingarm is necessary with these swaps, but it cant hurt. Plus the stock chain adjusters are crappy. I suppose one could pull them out and put measurements on them with a grinder.

I can tell you from my experience that not all grom parts bolt on. I bought grom chain adjusters that just barely don't fit in the Vader swingarm. I also bought rearsets that all align with our bikes but I had to do a reverse shift and make a new swingarm bolt from hardened all-thread. Maybe I'll take a $75 chance on a grom swingarm though.

I'm glad I didnt shell out for just chain adjusters then. They all seemed to be 60 bucks or so anyways. I figure $75 bucks is worth it just to ditch those chain adjusters.

[Whisky]

You need to grind on the frame where the swingarm mounts a tiny bit. As for the rubber bushings. They wear out sooner and I myself didnt want to take arm off again plus they make the bike feel much more solid. I wanted better adjusters without modding the adjuster some they won't fit in the clone arm and being $180. + For the arm extension w/adjusters I wasn't about to do any grinding on them.

[scoot newb]

I found an example of the (Hellcat) wiring. Should be easy but how do I know which yellow wire is which (coming out of the 190)?

https://imgur.com/hMFpVAi.jpg

[Whisky]

Doesn't matter. Both yellow are lights

[scoot newb]

Oh cool. So after more reading it looks like there isn't any way to make the cluster display which gear it is in but it will light up neutral?

Just to confirm, for the Hellcat nothing else is needed besides the motor? No special wiring harness, replacing the gas tank, weld a nipple to the bottom of the gas tank, special throttle body, oil catch, oil pump, oil cooler... etc etc. Just the motor, 2 bolts, 5 wires?

That's correct. Engine itself only has a neutral gear position indicator...no way to get gear indication through your stock display cluster.

If you really need a gear indicator there's an aftermarket/universal one that I bought (yet to install or test it though): https://www.amazon.com/dp/B07H7F8DKY/ref=cm_sw_em_r_mt_dp_U_VjaTCbP1VFX3C

No special wiring harness is needed. Nothing involving the gas tank needs to be done, no throttle body and no oil pump.

You do need an oil cooler, but the PitsterPro zs190 comes with one! Most places include it with the engine along with a Keihin PE28 carb knock-off. Highly recommend you run an oil cooler one since these are air cooled engines, not running one is very risky. You can find a spot to mount it on a bracket where your old airbox used to be attached to the frame.

Oil catch can is also highly recommended at least while you are breaking the engine in. You'll get a lot of spit back coming out the crankcase breather tube...best to have it directed into a receptacle rather than all over your tires/chain/roads.

[Whisky]

I've been reading that you can pull the gear sensor off of your 125 and put it on the 190. I'm still looking into that so I'm not 100% sure as of now. Yeah an oil catch can is a must during break in forsure.

You can cut, solder and use the stock harness to plug in direct to the zs190's neutral wire...but the zs190 engine itself does not have any wiring or sensors to read out gear position besides N...

I'm 95% sure on this. (I've read just about every post in the zs190 Swap Shop on Facebook lolol) If you connect the neutral wires via the harness connectors, it just makes it easier to disconnect everything should decides to go back to your old 125 engine. I think thats the only benefit. But hey I could be wrong on all of this!

Here's a great video on wiring the zs190 -

Thanks for the heads up! I think my swingarm is coming today. Where on the frame will I need to grind? Probably will make sense when I try to bolt it up?

Yeah u will know, where it bolts to the frame, some ground the swingarm but since I have the brass bushings I did the frame.

[Whisky]

I did find out that u can swap the gear sensor from the 125 to the 190 and it will show at least N 1 2 3 4 maybe 5th

Looking at pictures of one, it looks like a very simple swap! two screws and thats it?

How do you connect a gear indicator from the 190 to the cluster? I didn't notice any wires for it coming from the engine (pictures only).

You install the sensor from the 125 to the 190

Finally got my old swingarm off last night. Take about a blade length off of the right side of the frame?

[Whisky]

Yep. Easy money.....

[PhildoScaggins]

Yep. Easy money.....
sweet. I figure with everything torn apart I might as well replace my rear sprocket as well. Is the grom sprocket a direct fit do you know?

[Whisky]

Yes bolts right on. Also a good time to put grom wheel bearings in if u ever have plans to swap in a 190cc. I also changed the rear hub and the rubber pucks to Grom in preparation for the 190. I am amazed by the difference in quality, huge improvement.

Heres the sprocket I got-this is a 32t I currently have a 34t on the bike.

[PhildoScaggins]

Awesome. I'm probably gonna get everything together and running before I get new sprockets and a chain. I'll probably upgrade the hub and bearings at a later date. Tonight I grind the frame. Kinda nervous lol.

[Whisky]

I'm sure it all went fine.

[PhildoScaggins]

I'm sure it all went fine.

It did! Luckily I had some friends to hold the bike up, and hold a flashlight for me. Have you done your motor swap yet? I'm curious if the carby needs tuning or if its good to go right out the box. Still have not really looked into how to mount the oil cooler either.

[Whisky]

No not yet. I have a few more things I want to do first. I heard a re-jet is to be expected on the carb and the oil cooler mounts on the bracket where the horn is and then just mount the horn somewhere else. I'm guessing it's probably going to be a mid to late summer project. I already have the motor but I just have to many other things to do first.

[Whisky]

If your somewhat mechanically inclined it should be just a couple hours job, I know forsure it won't take long. I think changing the swingarm is probably more involved than swapping the motor.
